PHYSIOLOGICAL CHEMISTRY. Physiological Chemistry. 867 Carbon Monoxide in Normal Blood. RAPHAEL L~PINE and BOULUD (Contpt. rend. 1906 143 374-375).-Carbon monoxide occurs in the blood of normal dogs (Nicloux) and in cases of anzmia. The view that oxalic acid is its source is supported by the fact that intravenous injection of sodiuni oxalate in dogs increases the amount present eight- or ten-fold. I n asphyxia however the formation of the gas is prevented. Dextrose or lsevulose similarly administered has n similar result ; this is attributed t o increitsed oxalic acid formation. Tartaric acid produces the same effect but less rapidly whereas lactic acid does not. W. D. H. Hydroxyl-ions of Foetal (Placental) Blood. ALEXANDER SZILI (P'iiyer'g Archiv 1906 115 72-81).-The placental blood has the same amount of titratable alkali as that of the mother. The two are in osmotic equilibrium.I n both cases the smallest'amount of hydroxyl- ions does not correspond with the lowest amount of titratable alkali. W. D. H. Alcohol in Normal Blood and Tissues.

These were obtained originally in 1558. The facts are believed to be important in view of the calorific value of alcohol. W. D. H. Glycerol of the Blood and its Investigation by Zeisel’s Iodide Method. FRANZ TAR’GL and STEPHAN WEISER (P’uger’s Archiv 1906 115 152-174).-The blood contains free glycerol ; glycerylphosphoric acid could not be found.Glycerol is present in the plasma not in the corpuscles. Horses’ blood contains 0.076 horses’ plasma 0.095 and ox-biood 0.07 gram of glycerol per 1000 grams. W. D. H. The Sugar of the Blood. RAPHAEL LBPINE and BOULUD (Compt. rend. 1506 143 500-504 539-542).-The sugar of the blood is mainly in combination and this ‘‘ masked sugar” is liberated with comparative ease. The total sugar obtained from the blood is increased by the action of phloridzin and by the enzymes emulsin and invertin and also to nearly as great an extent by merely keeping the blood at 60° a temperature sufficiently high to prevent glycolysis but not high enough to inhibit the ferment which presumably disengages the sugar. The amount of increase in the sugar is not constant.The sugar of noriiial serum does not dialyse but when the masked sugar has been liberated it passes through. This favours the sup- position that the sugar is not free in the blood but that it is com- bined loosely with albuminous material. If this is so the fact that i t does pass readily into the urine is intelligible. W. D. H. Amino-acids in Blood and Lymph. WILLIAM H. HOWELL (Amer. J. Physiol. 1906 17 273-279).-Sy means of dialysis through collodion membranes amino-acids may be separated from both blood and lymph by means of P-naphthalenesulphonic chloride. I n the blood a positive reaction is obtained even after fifty hours’ abstin- ence from food but much more of these substances are obtained in well-fed animals especially in the portal blood.The membrane used is permeable to proteoses and peptone but none mas found. The portal blood (owing probably to a higher percentage of proteid) has a permanent greater osmotic pressure than that collected from other parts. W. D. H. Non-coagulable Proteid in Blood. WILLIAM H. HOWELL (Arne?.. J. Physiol. 1906 17 250-296).-After the principal proteids of blood have been removed by heating in feebly acid reaction (acetic acid) to 50-85” a proteid (ChabriB’s albumon) remains in solution ; it is however precipitated partially by prolonged boiling if the re- action is made strongly acid. It is not a peptone or proteose; it con- tains iron and a considerable amount of lecithin which can be com- pletely removed by boiling with alcohol. If serum-albumin is isolated and dialysed it is not coagulable by heat in the presence of sodium potassium or lithium salts but it is in the presence of ammonium barium calcium or magnesium salts.Globulins treated in the same way are heat-coagulable in the presence of both sets of salts,ABSTRACTS OF CHEMICAL PAPERS. 869 Fractional precipitation with salts is an unsatisfactory method of obtaining pure products. After a proteid has been salted out by ammonium sulphate i t is more susceptible to precipitation by heat or by dialysis. It is suggested that the term serum-globulin should be restricted to euglobulin. The proteid left in solution after dialysis shows the essential properties of an albumin modified by combination with lecithin or a lecithin-containing complex. W. D.H. Composition of Body- fluids in Marine Animals. SILVESTRO BAGLIONI (Beitr. chenz. PhgsioZ. Path. 1906 9 50-66).-The blood serum of the dog-fish shows great variations in its percentage of pro- teid ; the amount of non-proteid nitrogen is almost as great ; this is mainly due to urea as others have pointed out. During hunger the proteid nitrogen falls. The urea concentration in the blood is about three times greater than in the urine. I n other selachian fishes the same holds good but the actual amount of urea in the blood is smaller. I n the teleostean fishes on the other hand the conditions are similar to those in land animals. I n the body fluids of various invertebrates the amount of prcteid is very variable but is least in those lower forms which have not a closed vascular system ; in higher molluscs and arthro- pods the amount of proteid is important; the amount of extractive nitrogen per cent.is in the second or third decimal place; the amount in the urine is greater. Octopus’ urine contains proteid; this may be an ‘‘ alimentary albuminuria.” The statements are all illustrated by tables of analyses. W. D. H. Relative Concentration of Calcium Ions in reference to the Reversal of the Polar Effects of the Galvanic C u r r e n t in Paramcecium. FRANK W. BANCROFT (J. Phpsiol. 1906 34 444-463).-1f Para~naxia are washed in distilled water and then sub- jected to weak solutions of many salts they swim towards the anode and the behaviour of the cilia indicates that the anode is the stimu- lating electrode. Complete absence of galvanotropism is best produced by salts which diminish the concentration of free calcium ions.The character of the galvanotropism depends on the relative amount of these ions which are present. W. D. H. Relation of Ions t o Contractile Processes. I. Action of Salt Solutions on Ciliated Epithelium. RALPH S. LILLIE (Anzer. J. Physiol. 1906 17 89-142).-The toxicity of numerous salts on cilia is described with full detail and special attention is directed to antagonism o r antitoxic action; this is in general due to an approxi- mate equalisation of the opposite actions of anion and cation on the colloids of the tissue. Hence salts the toxicity of which is due to predomi- nant anion action require salts with active cations to counteract them and vice versd. W.D. H. The R61e of Elementary Nitrogen in Animal Metabolism. CARL OPPENHEIMER (Chem. Centr. 1906 ii 809-810 ; from Biocherm. Zeit. 1 177-182).-Experiments on healthy and diabetic dogs and also on VOL. xc. ii 59870 ABSTRACTS OF CREMICAL PAPERS. rabbits were made in order to ascertain whether atmospheric nitrogen plays any part in metabolism. The results were negative. W. D.H. Calcium and Magnesium Metabolism. S. GOITEEN (PfEGger’s Archiv 1906,115 118-151).-1f the diet is rich in calciuru and magnes- ium the body enriches itself with these substances whilstl it loses them if the food contains but little. These changes mainly affect bone and muscle ; the variations in other organs especially as regards ruagnesium are very small. Metabolism Experiments with Organic and Inorganic Phosphorus.J. A. LE CLERC and FRANK C. COOK (J. Biol. Chem. 1906 2 203-216).-The nitrogen retairied in rabbits and dogs is usually lowered (although the nitrogen balance is not necessarily negative) by the addition of inorganic phosphorus (phospbates) to the normal diet. If the food is poor in phosphorus the addition of inorganic phosphorus lessens the digestibility of the nitrogen and the nitrogen and phosphorus balances are generally negative. Organic phosphorus favours nitrogenous metabolism and increases the nitrogen and phosphorus retention. The phosphorus from wheat bran is specially valuable in this direction. The added phosphorus is never retained if the diet is normal. Organic phosphorus was never found in the urine. W. D. H. W. D. H.Digestibility and Utilisation of some Polysaccharides derived from Lichens and Marine Algix!. T. SAIKI (J. Biol. Chem. 1906 2 25 1-265).-Experiments with lichenin from Iceland moss Agar-agar and preparations from kombu makame and other Japanese fungi indicate that the polysaccharides present are not readily transformed into sugar by enzymes of animal or vegetable origin. W. D. H. Nitrogenous Metabolism as affected by Diet and by Alka- line Diuretics. H. D. HASKINS (2 Biol. Chem. 1906 2 217-229).-1n diets containing a t least 5 grams of nitrogen daily whether consisting of animal vegetable or mixed foods the ammonia excreted varies with the total nitrogen and the relative ammonia nitrogen to total nitrogen remains constant (not the abslJute amount of ammonia as Folin states).The administration of sodium hydrogen carbonate and sodium citrate reduces the ammonia to one-third of the normal and the urea increases correspondingly. I n this case the fixed alkali given takes the place of ammonia in neutralising acids formed in the body and this allows more ammonia to be converted into urea. The experiments were made on men. ERNST LAQUEUR (Chem. Centr. 1906 ii 10T4; from Arch. exp. Path. Pharm. 55 240-262).-0n the supposition that the elective action of quinine on metabolism is duo to elective action on enzymes the following six ferments were selected for experiment the autolylic ferment of the liver pepsin rennin gastric lipase and the catalase and oxydase of the blood. The tables given W. D. H. Action of Quinine on Ferments.PHYSIOLOGICAL CHEMISTRY.871 show that quinine influences their actions to varying degrees but the application of these results to metabolic processes is still for the future. W. D. H. Concentration of Hydrogen Ions in the Contents of the Fasting Human Stomach. FRANZ TANGL (PLfiiiyer’s Archiv 1906 115 64-71).-The hydrogen ions in the contents of the fasting stomach arise from hydrochloric acid t h a t being the only acid present ; the amount varied from 0.05 to 0.15 per cent. W. D. H. The Behaviour of Lecithin to the Lipolytic Ferments. C. .SCHUMOFF-SIMANOWSKI and NADINE SIEBER (Zeit. physiol. Chem. 1906,49,50-63).-Lecithin is decomposed by the steapsin of the gastric juice but much more energetically by that of the pancreatic secretion. Lipases from plants act similarly. The lipase of the blood and blood- serum has no such effect.W. D. H. Influence of Bile on Pancreatic Ferments. OTTO VON FURTH and JULIUS SCHUTZ (Beitr. chem. Physiol. Path. 1906 9 28-49).- Bile favours the lipolytic action of pancreatic steapsin ; a small quantity will raise the action fourteen-fold. Small changes in alkalinity have no effect and bile ash has no such action. The action is due to the bile salts especially to their cholic acid component; a few milligrams of a salt of this acid have a strong effect. Deoxy- cholic acid is nearly as active but oxidation products of cholic acid (cholanic bilianic and cilianic acids) are inactive. A. W. Hewlett’s statement that lecithin favours the action is confirmed but the action of bile is not due to its lecithin.The degree of activation produced by bile and its salts is very variable and so must be influenced by other factors. The favouring action of bile on trypsin is in- constant and its intensity much less than the similar action on the fat-splitting enzyme. W. D. H. The Cleavage of Food-proteid in the Intestine. OTTO COHNHEIM (Zeit. phpiol. Chem 1906 49 64-71).-The combined action of pepsin and erepsin is sufficient t o produce complete or almost complete cleavage of proteids. The experiments were made in uitro. W. D. H. Chemical Stimulation of Cerebrum. SAMUEL 5. MAXWELL (J. Biol.

Physiol. 1906 17 8-14).- Hypertonicity depresses the contractility and excitability of skeletal muscle. Hypotonicity increases these properties. The action is on the muscular fibres themselves because curare does not influence the above results. W. D. H. Influence of Temperature on Striped Muscle and its Relation to Chemical Reaction Velocity. THEO. C. BURNETT (J. Bid. Chem. 1906 2 195-201).-The processes underlying muscular contraction are chemical in nature.A rise of 10’ in temperature doubles or trebles the velocity of a reaction. The longth of the latent period was made the basis of calculation and the formula would be latent period a t tn latent period a t t n + 10= 2 or 3. The results show that the figure is usually near 2 or between 2 and 3. Extractives of Muscle. V. Carnitine. R. KRIMBERG (Zeit. physiol. Chena. 1906 49 89-95. Compare this vol. ii 781).-The substance in meat extracts described as carnitine is allied t o the betaine-choline group. It contains trimethyIamine. A nitrogenous acid was also separated as a barium salt but the composition of this second component of the carnitine molecule is not yet decided. W. D. H. W. D. H. The Relative Proportions of the Proteids of Muscle in Physiological and Pathological Conditions.PAUL SAXL (Beitr. chem. Physiol. Pccth. 1906 8 1-2?).-Investigations on the chemical composition of muscle made after rigor mortis has set in give an incorrect view of its proteid constituents. The three principal varieties of muscle (voluntary cardiac and smooth) differ in their proportion of soluble and insoluble proteids (Euscle-plasma and muscle-stroma). The porportion in the three kinds of muscle is respectively 7 1 1 3 and 1 4. The proportion between the soluble proteids paramyosinogen (von Furth’s myosin) and myosinogen (von Furth’s myogen) is 1 5. Muscular activity has no influence on such figures. I n fatty degeneration of the heart the total proteids are less and in hypertrophy greater than nor- mal.I n phosphorus poisoning the soluble proteids of the heart increase and the insoluble decrease. Rigor nzortis is due to proteid coagulation and the insoluble proteids therefore increase ; the phenomenon is most. marked in the voluntary muscles for they contain so much soluble pro- teid to undergo coagulation; in heart muscle it is less marked and in smooth muscle absent. I n fatty hearts it is more marked than in normal cardiac tissue. The phenomenon is irreversible. W. D. H. RUDOLF TURKEL (Beitr. chem. Physiol. Puth 1906 9 89-90).-Seegen states that the total carbohydrate of the liver j s greater than the sum of its sugar and glycogen and that after both are removed a material remains which is precipitable by alcohol and yields sugar by boiling with acids. In other organs he could not discover this substance.I n the present research no sugar-yielding substance was found in the liver after the removal of proteid glycogen and the sugar already present.

ARIMA (Zeit. plk~siol. Chem. 1906 49 108-1 12).-Magnus Levy states that in liver autolysis the lactic acid obtained is a mixture of the optically in- active with the dextrorotatory acid in aseptic autolysis the latter comprises 40 per cent of the whole whilst in antiseptic autolysis i t is only 10 per cent. The present research was carried out with bull’s testes ; during autolysis the lactic acid increases; the zinc salt was identical with that of the dextrorotatory lactate.The nature of the material which gives rise to the acid presumably by ferment activity is unknown. Other organs are being examined. W. D. H. Influence of Alkalinity on Liver Autolysis. ALEXIS VON DRJEWEZKI (Chern. Centr. 1906 ii 806; from Uiochsm. Zeit. 1 229-245).-1f t h e concentration of alkali is 0.2 to 0.3 per cent. autolysis r u n s its usual course except that proteid cleavage occurs more slowly. If the alkalinity is raised to 0.5 per cent. (in terms of sodium carbonate) autolysis ceases. I n ordinary liver autolysis proteoses are found abundantly. Among the mono-amino-acids glycine and leucine were identified ; leucine comprises the main amount of this fraction.W. D. H. Proteolytic Action of Animal Tissue Juices and of In- t e s t i n a l Juice. EmL ABDERIIALDEN and YUTAKA TERUUCHI (Zeit. physiol. Chem. 1906 49 1-14).-The authors have already shown that aqueous extracts of ox-liver contain active proteolytic ferments which split dl-leucylglycine and glycylglycine. The present paper is a continuation of the work with other organs and other peptides. As a rule the expressed juice was used instead of or as well as aqueous extracts. Bacterial action was excluded by toluene. Ox-liver juice splits dl-leucyl-glycine and glycyl-dl-alanine but not racemic leucyl- leucine nor glycine anhydride. Ox-muscle juice contains little or no proteolytic ferments and so contrasts with rabbit’s muscle ; i t decom- poses glycylglycine dl-leucylglycine and glycyl-dl-alanine but only to a slight extent.Dog’s kidney juice is also active but i t and intestinal juice from the same animal do not decom- pose hippuric acid. Dog’s liver juice is only active in the resolution of glycylglycine and glycyl-Z-tyrosine. The intestinal juice secreted by the dog and ox is also very active in resolving the same peptides. Not only the organ but the blood-serum of some animals is active in the same direction although here possibly trypsin absorbed from the intestine has in part to be dealt with. Dog’s muscle juice is more active. W. D. H. The Behaviour of Leucylphenylalanine Leucylglycyl- glycine and Alanylglycylglycine toward the Liver-juice of the Ox. EMIL ABDERHALDEN and PETER RONA (Zeit. physiol. Chem. 1906 49 31-40).-The three peptides mentioned are split to some extent by the juice expressed from ox-liver.The main object of these and similar experiments is to learn something of proteid cleavage and proteid-synthesis in the tissue-cells of the body. No reversible action874 ABSTRACTS OF CHEMICAL PAPERS. was ever observed ; various mixtures of amino-acids were never found altered by pancreatic juice or various tissue juices. No synthesis of peptides occurred. W. D. H. Phosphorus and Calcium of Human Milk. ALFRED W. SIKES (J. PAysioZ. 1906 34 464-480).-The average amount of phosphoric acid in human milk during the first fortnight after lacti-ltion starts is 0.029 per cent. The percentage of non-proteid phosphoric acid varies in primipara (0+026) and multipara (0.018) ; the percentages of proteid phosphoric acid are 0.01 3 and 0.01 1 respectively.I n primipara the total rises up to the ninth day; in multjpara the maximum is a little earlier. The variations are mainly due to the non-proteid phosphoric acid. The average amount of calcium for the same period is 0-03 per cent. and rather less in primipara. The greater part (84 per cent.) is combined with proteid. Variations from the average are small. The proportion of calcium to proteid is 1.06 100. W. D. H. Influence of Added Substances on the Rennin Coagulation of cows’ Milk. CHANA SlllELIANSKY (AT&. Rygiene 1906 59 187-215).-The longer milk is heated before the addition of rennin the longer i t takes to coagulate and the softer and in smaller pieces is the coagulate ; similarly on dilution with water the moment of coagulation is delayed but the nature of the precipitate does not seem to be altered.On the addition of mucilage prepared by heating starch with water and rubbing the pulp through a fine sieve the time required for coagulation is if anything lessened whilst the coagulate becomes softer and more loosely packed. Sodium carbonate delays coagulation and gives a softer coagulate; sodium chloride has the same influence when at least 4 per cent. of the salt is added ; calcium salts have a similar action. A slightly alkaline milk coagulates more slowly and in finer flakes than a neutral or faintly acid milk. Milk sugar dextrose gucrose or mannitol are without influence on the coagulation. E. F. A. Amino-acids in Normal Urine.JULIUS WOHLGEMUTH and CARL NEUBERG (Chem. Centr. 19U6 ii 895 ; from Med. Klin. 1906 No. 6). -From 8 litres of urine 0.2 gram of glycine (as barium naphthyl- carbimideglycine; compare Abstr. 1905 i 647) or a percentage of 0.0025 was obtained. The quantity is not of physiological importance. W. D. H. Endogenous Purine Excretion in Man. JOHN J. R. MACLEOD and H. D. HASKINS (J. Biol. Giiern. 1906 2 231-242).-The excre- tion of endogenous purine substances is not affected by very great variations in diet provided that this is purine-free. In different individuals the amount varies. Sodium citrate and sodium hydrogen carbonate if given in amount suEcient to make the urine alkaline increase the endogenous purine excretion ; this effect lasts for some days even after t h e reaction of the urine again becomes acid.W-.

Whether these are precursors or degradation products of creatinine will be discussed i n a future paper. The base described in the first paper of the series which is toxic was separated as a gold salt ; it is di-acid has the formula C13H2RN404 and the name kynosine is proposed for it. W. 1). H. Phosphorus Content of Faxes Fat. JOHN H. LONG and W. A.JOHNSON (J. Ante~. Ciiem. Soc. 1906 28 1499-1503. Compare this vol. ii 637).-The amount of fat in eight samples of faeces varied from 8.60 to 19.45 per cent. (calculated on the dry material) whilst the phosphoric acid (P20,) i n the fat varied from 0.20 to 3.66 per cent. It is probable that the phosphorus is present in the form of “ lecithans ” or “ phosphatides,” substances in which the phosphorus and nitrogen ratios are variable. The probable sources of these phosphorus com- pounds in faxes f a t are discussed. E. G. Ascitic Fluid containing Albumin Soluble in Acetic Acid. BRETET (Awn. C J h . CcnaZ. 1906 11 368-370).-An ascitic fluid examined by the author contained 33.7 grams per litre of albumin which was readily soluble in acetic acid. Heating the fluid alone or with the addition of a little nitric acid produced an abundant coagulum but the addition of acetic acid entirely prevented coagulation even at a boiling temperature.The albumin present in the urine of the patient was coagulable in the presence of acetic acid. w. P. s. Hydrochloric Acid in Cancer. S. MONCKTON COPEMAN and H. WILSON HAKE (Lancet 1906 ii 1276-1277).-From the examina- tion of the stomachs of 500 mice the conclusion is drawn that the hydrochloric acid is higher in those suffering from cancer than in normal mice. The analyses however were not made on the gastric conterits only as in the work of previous investigators but on the contents plus the gastric tissue. W n. H. Cancer. CARL NEUBERG (Chem. Centr. 1906 ii 902 ; from Zed. Krebsforsd. 2 171.Coinpare Abstr. 1905 ii 338).-A cancerous growth of the liver secondary to one in the stomach was examined two- thirds of its nitrogen was present in the form of mono- and one-third in di-amino-acids ; bases sulphur phosphorus arid ash were also esti- mated the net result being that the cleavage products are approximately in the same proportion as in normal cell-globulins. The statement of Blumenthal and Wolff that the fresh turnours resist peptic but not tryptic digestion was confirmed. The nucleo-proteid was prepared from an aqueous extract by precipitation with acetic acid and an elementary analysis made; the percentage of phosphorus was 3.97. It gives intense phloroglucinol and orcinol reactions. On hydrolysis it yields orthophosphoric acid pentose and purine bases,876 ABSTRACTS OF CHEMICAL PAPERS.Autolysis in carcinomatous tissue increases under the action of Rontgen rays and still more so under that of radium emanations. W. D. H. Hydroxyl-ion Concentration of Diabetic Blood. H. BENEDICT (Pfliiyer’sArchiv. 190G,115,106-11’1).-The coricentration of hydroxyl ions in diabetic blood does not differ from that in normal blood and even in diabetic coma a depression of the concentration is not con- stantly present. The observations do not support the view that the coma is produced by acids. W. D. H. Effect of Castration on Metabolism in Osteomalacia. FRANCIS H. MCCRUDDEN (Amer. J. Physiol. 1906 17 210-217. Com- pare Abstr. 1905 ii S45).-Castration is not a permanent cure. The present paper continues the history of the same patient.The course of nietaholism later was different from what it was before the opera- tion but so little is known of inorganic metabolism that further experi- ments on normal people are contemplated. The disease is attributed by some to disease of the ovai,ies but these are usually found to be normal on removal. An incapacity of the ground substance of bone t o fix inorganic salts or an insufficient supply of such salts in the blood do not seem to be the causes of the disease. There is however a specially active kata- bolism of the bony tissue and this occurs even in ordinary pregnancy when the developing embryo requires a large snpply of lime. An abnormal sulphur metabolism which occurs is secondary to this. Castration certainly prevents pregnancy but it has no influence in the ultimate and a t present unknown cause of the disease W.D. H. Behaviour of Bromides in the Body. H. VON WYSS (Chem. Centr. 1906 ii 1077-1078; From Arch. exp. Path. Pharm. 55 263-287).-Administration of bromides leads to their appearance in the urine and this goes on for a fortnight after the cessation of the administration. Large amounts are thus retained in the body for a considerable time. The brain liver and kidneys do not retain much ; most was found in the blood serum. It is partly excreted in gastric and intestinal juices. W. D. H. Effect of Saline Purgatives. JOHN AUER (Amer. J. PAysioZ. 1906 17 15-25).-Subcutaneous and intravenous injection of magnesium sulphate and chloride sodium sulphate phosphate and citrate does not produce purgation in rabbits; they however do produce a moderate increase of peristalsis except in the case of magnesium sulphate which produces no effect at all.W. D. EL Biochemical Studies on Chloroform. JOHANN FEIGL and HUGO MEIER (Chem. Centr. 1906 ii 1135; from Bioclhern.

Action of Chloral Hydrate on the Heart. A. J. CARLSON (Amer. J. Plu~siol. 1906 1’7 1--7).-ChloraI hydrate has a primary stimulating action on the heart ganglion of Linaulus but if the drug is dissolved in plasma o r sea-water surrounding the heart the muscular tissue is depressed without primary stimulation.If the solution is applied to the entire heart the tissues are paralysed in the following order ganglion nerves or nerve-endings muscle. These results are discussed in relation to similar experiments by Rohde and others in reference to the mechanism of cardiac excitability but no clear state- ment of the author’s views is made. W. D. El. Importance of Thio-compounds in the Body. ALBERT EDINGER and PAUL CLmIENs (Chem. Cent?.. 1906 ii 1076-1077; from Zeit. klin. Med. 59 2 lS-232).-The antiseptic action of quinoline bismuth thiocyanate is due to the setting free of hydrogen thiocyanate and this action is supported by the presence of quinoline thiocyanste.Such compounds increase the excretion of sulphur and nitrogen and lower the acidity of urine. Their toxic action is powerful and resembles that of hydrocyanic acid. By Rupp’s method very small quantities of thiocyanate were found and estimated in various normal organs even if none had been administered. W. D. H. Physiological Action of some Bases obtained from Ox- muscle. FRIEDRICH KUTSCHER and ALFRED LOHMANN (P’iiger’s Archiv 1906 114 553-568).-Particulars of lethal doses and physiological action on various animals are given in reference to novaine oblitine ignotine and neosine. Oblitine acts harmfully on the intestine and produces necrosis of the mucous membrane; it stimulates its muscular coat ; i t causes a lowering of arterial pressure and irregularity of the ventricle of the isolated frog’s heart; it stimulates salivary secretion.After subcutaneous injection none is found in the urine but after it is given by the mouth some passes as such through the body of the cat. Novaine has a very similar action and some passes unchanged into the urine after subcutaneous administration. Probably both substances belong to the choline group. Only a very few experiments are recorded with ignotine and neosine ; the former has a stimulating action and no effect on arterial pressure ; the latter lowers arterial pressure slightly. W. D. H. Subcutaneous Injection of Adrenaline. T. R. ELLIOTT and HERBERT E. DURHAM (J. Physiol.1906,34- 490-49S).-Subcutaneous injection of adrenaline in cats over prolonged periods did not as some have stated cause any production of anti-adrenaline. The muscles of the circulating system were unaffected. I n one animal the cervical sympathetic was unduly irritable but it is doubtful i f this was an effect of the drug.

D. H. Their primary action. Action of Ergot on the Alimentary Canal. SAMUEL J. MELTZER and JOHN AUER (Anzer. J. Plipiol. 1906 17 143-166).-Ergot in- creases the natural movements of the stomach and intestines and augments the motor effect of the vagus.I t s effect is antagonised t o a great extent by atropine. 157. D. H. Acid Intoxication. ALEXANDER SZILI (PfEiiger’s Archiv 1906 115 82-1 05).-Tmo questions were investigated namely the altera- tions in.the concentration of hydroxyl ions in the blood produced by intravenous injection of acid and the depression in tile same produced by lethal doses of acid. I t was shown that the alkalinity of the blood does not sink in proportion to the amount of acid given and that the cells only yield their alkali slowly to the blood to equalise the loss of alkalinity there. I n fatal cases in rabbits the concentration of hydroxyl ions sinks by 95 per cent. and of titratable alkali by 78 per cent. I n dogs the corresponding numbers are 96 and 75 respectively. The serum of all animals still reacted alkaline to lacmoid.In the experiments recorded the dogs died more quickly than the rabbits which is contrary to the generally accepted belief in the greater susceptibility of herbivora to acid poisoning. This point is discussed at length W. D. H. Phosphorus Poisoning. EMIL ABDERHALDEN and ALFRED SCHLT- TENHELM (Zeit. physiol. Chem. 1906 49 41-46).-1n normal dogs peptides given by the mouth or under the skin are broken down and the.nitrogen is discharged as urea. This is due to the presence of enzymes in the cells which act like trypsin. I t was of interest t o ascertain if the same happens when the animal is poisoned with phosphorus ; dl-leucylglycine was given but no altered dipeptide was found in the urine ; small quantities of leucine and glycine were found but i t is uncertain if these came from the peptide administered; so in another experiment the liver juice of a dog poisoned by phosphorus was examined hut it cannot be stated with any certainty that its power of splitting peptides was less than that of normal liver juice.W. D. H.VEGETABLE PHYSIOLOGY AND AGRICULTURE. 879 Can small amounts of Copper induce Chronic Poisoning? MASATO TOYONAGA (Bull. Coll. Agr. T6ky6 Imp.

No copper could be detected ill the faxes unt'il after five months the daily amount was increased t o 20 mg. The rabbits died soon after- wards probably of cold. A small amount of copper mas found i n the liver but none i n the brain. There were no symptoms of poisoning. Experiments were also made with manganese.. A rabbit received 37 grams of manganese chloride in eleven months without any effect. N. H. J. AX. Hydrocyanic Acid Poisoning. ANGELO DE DOMINICIS (Chena. Centr. 1906 ii 620-621 ; from Boll. Chirn. 3 c c ~ r n . 45 367-372. Compare Abstr. 1905 ii 746).-The elimination of hydrocyanic acid occurs through the lungs. Some of the poison unites with the blood pigment t o form cyanohaemoglobin. W. D. H. Lysol Poisoning. FERDINAND BLUMENTHAL (Chem. Centr. 1906 ii 620 ; from Biochem. Zeit. 1 135-152).-The capacit,y of the organism to burn cresol is very great. By giving lysol to dogs in non- toxic doses the cresol ethereal sulphates and glycuronic acid in the urine rise in amount proportional t o the dose given. The destruction of cresol does not occur in the blood but in the tissues probably of the liver; the removal of its poisonous characters is largely due to union with sulphuric and glycuronic acids. W.

VEGETABLE PHYSIOLOGY AND AGRICULTURE. 879 Chemistry of Vegetable Physiology and Agriculture. Vitality and Activity of Technical Lactic Acid Bacteria. I. CARL WEHMEH (Chem. Zeit. 1906 30 1033-1034).-Lactic acid bacteria kept on dry calcium lactate for six years were still able to set up lactic fermentation of sugar even though they,had not formed any spores; after ten years the bacteria had completely lost their activity. Rough calculations showed that the bacteria were able to produce about ten times their own weight of lactic acid; the yield which does not as a rule exceed 60 to 70 per cent. is considerably influenced by the purity of the culture but i t is not as yet possible to account for the wastage in sugar. P. H. Fermentation of Milk. FERDINAND BLUMENTHAL and WOLFF (Chem.Centr. 1906 ii 900 ; from Cha~it&Ann. 29 12-18).-Milk which has been kept for years may contain 50 per cent. of the lactose originally present. In the spontaneous acid fermentation of milk880 ABSTRACTS OF CHEMICAL PAPERS. there is no essential peptonisation of proteids; large amounts of amino-acids especially leucine are formed. The only aromatic com- pound found is tryptophan. The amounts of acids are increased by prolonged putrefaction the lactic acid more than succinic acid. N. H. J. M. Micro-organisms of Natto. SHIN SAWAMURA (Bull. COX Agr. T6ky6 Imp. Cniv. 1906 7 107-IlU).-Natto is vegetable cheese prepared by fermenting boiled soy-beans. The micro-organisms con- sist at first chiefly of bacilli but subsequently micrococci predominate. Two bacilli were isolated one of which produces the desired taste and aroma but insufficient viscosity ; whilst the second produces cheese of stronger viscosity but less desirable as regards taste.It is probable that both bacilli are necessary for the production of perfect cheese. Both bacilli produce diastatic enzymes. Action of Copper Salts on the Germination of Penicillium. LE RENARD (Compt. rend. 1906 143 607-60S).-Spores of Penicilliuna crustaceuna are not killed (compare Benecke Abst’r. 1 S9 6 ii 572) but rendered inactive by treatment with copper salts (acetate chloride nitrate or sulphate) even in such dilute solutions as 0.00005 gram per litre and can be stimulated to germination by subsequent treatment with solut,ions of potassium ammonium or magnesium succinate or acetate of strengths comprised between decinormal and centinormal.31. A. W. The Separation of the Life and Ferment-action of Yeast. THOMAS BOKORNY (Pjiiger’s Archiv 1906 114 535-544).-Sulphuric acid (0.05 per cent.) renders zymase inactive and also kills yeast cells. The strength of the acid can however be adjusted so that the cells are killed whereas the activity of zymase is hardly aifected. Similar results were obtained with formaldehyde and mercuric chloride. They are stated quantitatively. Formation of Fuse1 Oil in Fermentation by Means of (‘ Acetondauerhefe.” HANS PRINGSHETM (Ber. 1906 39 3713-3715. Compare Abstr. 1905 ii S48).-The author confirms the results of Buchnm and Meisenheimer (this vol. ii 790) who found t h a t only very small quantities of fuse1 oil are produced when sucrose is fermented by expressed yeast juice.In the fermentation of sucrose by “ Acetondauerhefe ” no fuse1 oil was detected when the fermentation was conducted either in the presence or in the absence of leucine.

Compare Abstr. 1905 ii 473).-A sample of turned sake (rice wine) yielded a new variety of yeast Mycoderma saprogenes sak& The mycoderma grows on Mayer’s and Nageli’s solution contain- ing 9 per cent. of alcohol whilst Hayduck’s solution with 2 and 4 per cent. of acetic acid is unfavourable. It assimilates dextrose laevulwe,VEGETABLE PHYSIOLOGY AND AGRICULTURE.881 and sucrose and also to a less extent maltose and galactose. It ferments dextrose and galactose very feebly but not lsvulose sucrose and maltose and it does not assimilate nitrates and nitrites. When cultivated in Hayduck's solution for seventeen days a t 27-30' a trace of volatile substance resembling altered vinegar in taste is produced. After five months' cultivation in saki with 13-85 per cent. of alcohol a trace of ethyl alcohol was found but no aldehyde methyl alcohol or acetone. The mycoderma is at once killed a t a temperature of 70° and in five minutes a t 55". N. H. J. M. R6le of Enzymes in the Conversion of Organic Phosphorus Compounds in Germinating Seeds. W. ZALESKI (Chew,. Centr. 1906 ii 893-894; from Ber. deut. hot. Ges. 24 285 -29 l).-Experiments with seedlings OF Lupinus angusti- folius showed that the proteids containing phosphorus and phosphatides (chiefly lecithin) are decomposed by enzymes with pro- duction of inorganic phosphates.It is probable that the separation of phosphorus from proteids and proteoljtic decomposition may take place independently of each other.

Compare this vol. ii 299).-Phytolytic decomposition of aqueous carbon dioxide into formaldehyde and hydrogen peroxide with production of formic acid as intermediate product can take place in presence of chlorophyll when the necessary physical and chemical conditions are present independently of vital or enzymic activity.The process of photosynthesis can be reconstructed outside the green plant as far as the production of formaldehyde and oxygen by introducing a suitable enzyme ; and as far as the production of oxygen and starch by introducing in addition certain kinds of non-chloro- phyllous living protoplasm. Formic acid is a product of the photolytic decomposition of carbon dioxide in presence of an inorganic uranium salt ; formaldehyde is probably an intermediate product. N. H. J. M.882 ABSTRACTS OF CHEMICAL PAPERS. Changes in the Nitrogenous Constituents of Green Plants in the Absence of Light. A. KIESEL (Zeit. physiol. Chem. 1906 49 72-80).-Ry keeping a green plant (T9*ifoZizcm pratense) in the dark theie is not only an increase in its asparagine as had been previously stated but also in other amino-acids especially leucine and also in the bases precipitable by phosphotungstic acid among which arginine was identified; histidine is probably present also but the amount obtained was too small to admit of a complete analysis.These bases cannot be obtained from healthy plants. W. D. H. Direct Action of Light on the Transformation of Sugars absorbed by the Young Plants of Pinus Pinea. W. LUBIMENKO (Compt. rend. 1906 143 516-519. Compare this vol. ii 624).-Experiments were conducted on embryos of Pinus Pinea placed in sterilised solutions of sucrose dextrose maltose lactose galactose or arabinose and exposed to light of varying intensity from full daylight to complete darkness.The young plants were weighed a t the beginning and the end of the experiment and it was found that whilst the light had no effect on the assimilation of maltose lactose l;evulose or galactose the absorption of sucrose dextrose or arabinose varies greatly with the intensity of the light. I n the original the results are represented in curve form the per- centage increase in weight as ordinates being plotted against the intensity of the light as abscissE; the maximum increase in weight corresponds with an intensity of light too feeble for the assimilation of carbon dioxide by the chlorophyll and as the intensity of the light increases the amount of sugar absorbed by the plant diminishes but a t the same time the plant increases in weight owing to the decom- position of carbon dioxide by the chlorophyll.M. A. W. Nature of the Cyanogenetic Glucoside in the Seeds of Eryobotyra Japonica. HENRI HI~RISSEY (J. Pharm. Chim. 1906 [ vi] 97 350-355).-Fresh seeds of Eryobotyrn contained 1-1 .lo per cent. of amygdalin. No other glucoside acted on by emulsin was found. The leaves contain no cyanogenetic glucoside. N. H.

The oil also contains certain colouring principles. Z. K. Formation and Physiological Role of Pentosans in Plants. GIUSEPPE A. CALABBIN (C'herrz. Centr. 1906 ii 964; from Staz. spev. agyav. ital. 39 69-96).-Pentosans seem to be formed in young plants the amount decreasing later on. I n different cereals the more resistant ones seem t o contain more pentosans than the others.The roots of sugar beet generally contain less sucrose when the amount of pento>ans is high. The amount of pentosans in plants is always greater when nutritive constituents are lorn. I. Canella Bark. JOSEF HANUS and PRANZ BIEN (Zeit. Nahr. Genussm. 1906 12 395 -407).-The quantity of pentosan contained in spices is fairly constant for one and the same kind the largest amount being found in the bark of Canella alba;; next in order of pentosan con- tent follow those spices which consist of the whole plant or leaves; then come barks fruits and seeds and lastly flowers. The quantity of crude fibre yielded by a spice is generally proportional t o the amount of pentosan present. Canella bark contains about 8 per cent.of mannitol together with smal; quantities of araban and galactan and traces of xylan. The residue obtained after extracting canella bark with water still contains polysaccharides which dissolve on treatment with 5 per cent. sulphuric acid and are afbparently xylan and dextro- san.

(2) A distinctly acid substance which separates from alcohol in white mammillary masses or a sticky powder melting a t 253-255'; it dissolves readily in benzene or chloroform and sparingly in ether or carbon disulphide and is possibly identical with the compound melting a t 250" described by Peano (Abstr.1903 ii 173). (3) A substance crystallising in tetrahedra with curved angles and melting a t about 236'. (4) A small quantity of an acid which crystallises in microscopic spherules (a octahedra) melts a t 165' and dissolves readily in alcohol or solutions of alkalis.

W. D. H. 60-2888 ABSTRACTS OF CHEMICAL PAPERS. Stimulating Action of Calcium Fluoride on Phmnogams. ICEIJIRO As0 (Bull. Coll. Agr. 7'6ky6 Imp. Univ. 1906 '7 85-89. Compare Abstr. 1903 ii 173).-The results of water and soil culture experiments indicated that precipitated calcium fluoride probably had some stimulating effect. I n water cultures of barley calcium fluoride exerted a moderate stimulating action. It is suggested that the more favourable results obtained with Wiborg phosphate as compared with superphosphate may be due to the presence of 1 per cent.of fluorine in the former. As regards Ampola's results (Bbstr. 1904 ii 767) it is pointed out that the beneficial effect of calcium fluoride cannot be due to liberation of hydrogen fluoride as carbon dioxide and weak acids have no action on it. N. H. J. M [Influence of Manganese and IronSulphatesand of Potassium and Sodium Silicates on Wheat and Barley]. JOHN A. VOELCKER (J. Roy. Agric. SOC. BngZ. 1905 66 206-211).-1n the case of wheat soaking the seed in solutions of manganese and iron sulphates (not more than 2 per cent.) is beneficial to ger,mination. Barley is also benefited by manganese sulphate and even 5 per cent. solutions are not injurious whilst iron sulphate has no effect on germination. Tho yield of wheat is increased by soaking the seed in solution of iron sulphate but not by manganese sulphate.Both salts when applied to the growing plant increase t'he yield of wheat a i d barley. Potassium and sodium silicates are beneficial to wheat and barley especially as regards the yield of straw. N. H. J. 1\1. Degree of Stimulating Action of Manganese and Iron Salts on Barley. TOMIO KATAYAMA (Bull. Coll. Agr. T6kyij Irnp Uniu. 1906 '7 91-93).-Whilet manganese sulphate (0,015 per cent.) gave with peas an increase of 50 per cent. of straw and 25 per cent. of seed the increase in the case of cereals was only about 10 per cent. Recent pot experiments with barley showed that 0.01 per cent. of manganese and iron sulphates produced moderately increased yields of straw and grain (6.2 and 7.2 respectively) whilst the application of larger amounts resulted in decreased yields.N. H. J. 31. Stimulating Action of Manganese on Rice. MUNESHIGI NAGAOKA (BuIZ. ColZ. Agr. T6ky6 Imp. Univ. 1906 7 '77-81. Compare ibid. 6 135)-Experiments on rice were repeated in 1904 under exceptionally favourable conditions of weather. The amounts of manganese sulphate applied varied from 30 to 170 kilos. per hectare and the greatest gain due to manganese was 15 per cent. with 77 and with 107 kilos. per hectare. The experiments mere continued in 1905 on the same soil now partially exhausted as regards minerals. Equivalent amounts of manganese sulphate chloride and carbonate (corresponding with Mn,Oa = 25 kilos per hectare) were compared. The carbonate produced a slightly increased yield of straw whilst with the sulphate and chloride the yield was reducid partly owing to acidityof the soil.N. H. J. M.VEGETABLE PHYSIOLOGY AND AGRICULTURE. 889 Stimulating Influence of Sodium Fluoride on Garden Plants. KEIJIR~ As6 (Bull. Coll. Agr. T&y6 Imp. [Yniv. 1906 7 83-84).- Pot experiments with HelicZirysum byacteaturn and Pedicellariu viscide showed that 0.02 gram of sodium fluoride in 8 kilos. of soil increased the yield of Pedicellarin but had very little effect on Helichrysum. With 0.2 gram of fluoride the result was almost the same as without fluoride. N. H. J. M. Condensed Vegetable Milk. Tomo KATAYAMA (Bull. Coll. Agr. (rcTkyb Imp. Univ. 1906,7,113-115).-The condensed milk is prepared by concentrating soy-bean milk (Inouye Abstr. 1896 ii 65) in a vacuum after adding sucrose (150 grams) and dipotassium phosphate (1 gram per litre). The product has aconsiderable nutritive value and can be used for preparing various foods.The presence of vegetable milk in ordinary condensed milk can he detected by adding sodium carbonate which produces a yellow coloration. Another means of detection is to add water (2 vols.) and a few drops of dilute sulphuric acid ; when distilled the characteristic odour of raw beans becomes noticeable. N. H. J. M. Vegetable Cheese from t h e Proteid of the Soy Bean. TOMIO KATAYAMA (Bull. Coll. Agr. I’dcy6 Imp. Univ. 1906 7 117-119).- Vegetable cheese was prepared by mixing pressed tofu (Abstr. 1896 ii 65) sodium chloride lactose and Swiss cheese (for the introduction of microbes). The mixture is kept moist for five months a t 15’.The product is grey and is free from holes even when a considerable amount of lactose is employed. The taste differs from that of Swiss cheese. N. H. J. M. In one experiment some casein was also added. Composition of Soils from French Guinea. ALEXANDRE HI~BERT (Bull. sbc. chim. 1906 [ iii] 35,1033-1038).-Sixty-three virgin and cultivated soils and subsoils collected by 31. Chevalier in various districts in French Guinea have been examined physically and chemi- cally and the results which are tabulated in detail in the original show that both the soils and subsoils are usually fairly rich in nitrogen and poor in phosphoric acid potash and lime. Agricultural Values of the Cacao Soils of S. Thome and the Gold Coast Colony. ALEXANDRE HBBERT (Bull. SOC.chim. 1906 [iii] 35,1039-104l).-Five samples of soil from cacao plantations in S. ThomB and three from plantations a t Aburi in the Gold Coast Colony have been examined physically and chemically and the results which are tabulated in detail in the original show that all the soils are deficient in lime and potash although comparatively rich in nitrogen and phosphoric acid. The deficiency in lime and potash is however less marked than in the case of the soils from French. Guinea (see preceding abstract). The composition of vegetable d56ris) obtained from a plantation a t Aburi is also given. SHIGEHIRA SUZUKI (Bull. Coll. dgr. T&y6 Imp. Uniu. 1906,7 95-99).-The amount of carbon dioxide liberated T. A. H. T. A. H. Formation of Humus,890 ABSTRACTS OF CHEMICAL PAPERS.from moistened leaves of Quemus serrata both alone and with addition of calcium and magnesium carbonates and dipotassium phosphate was determined every few days for about nine months. The results showed that magnesium carbonate promotes the libera- tion of carbon dioxide and that dipotassium phosphate has n very essential influence on the increase of carbon dioxide. Calcium car- bonate had the opposite effect. Leaves (with magnesium carbonate and dipotassium phosphate) which were first sterilised and then received the mycelium of a kind of Penicillium liberated only about a third as much carbon dioxide as in the control experiment. N. H. J. M. Influence of the Reaction of the Manure on the Yield. KEIJIR~ As6 acd RANA BAHADUR (Bull.Coll. Agr. Tijkyij Imp. Univ. 1906 7 41-46).-Pot experiments were made with peas and barley manured with disodium phosphate and with monosodium phosphate in conjunction with sodium nitrate and ammonium sulphate respectively. The results showed that the combination of acid manures or of alkaline manures is unfavourable the best results being obtained with mixtures of acid and alkaline salts. I n the case of rice sodium nitrate is unfavourable; ammonium sulphate with disodium phosphate gave the best result. I n experiments with onions ammonium sulphate gave far better results than sodium nitrate when applied in conjunction with disodium phosphate and p3tassium carbonate. The statement of Kruger and others that nitrification is unnecessary ammonia under suitable conditions being as efficacious as nitrate is confirmed.N. H. J. M. Application of Sodium N i t r a t e as Top-dressing for some Japanese Crops. KEIJIR~ As6 (Bull. Coll. Agr. T6ky6 Imp. Univ. 1906 7 75-76).-Upland rice Sesumum and Colocasicc antiquorum were manured with dung and superphosphate and with the same manures in conjunction with sodium nitrate as top-dressing. The nitrate increased the yield of Colocasicc but was almost without effect on rice and Sesurzzum. N. H. J. M. Manurial Value of Calcium Cyanamide. KEIJIR~ As6 (Bull. Coll. Agr. T d p 6 Inzp. Univ. 1906 7 47-52).-Experiments are described in which the effect of calcium cyanamide was compared with ammonium sulphate and with sodium nitrate. In the first series buckwheat Sesurnum and hemp were grown in soil unmanured for six years in large zinc cylinders sunk into the ground.Further experiments in pots were made with upland and paddyrice and hemp which were grown in alluvial sand and diluvial loam containing 1 and 10 per cent. of humus respectively. The results indicated that the manure is not inferior to ammonium sulphate and sodium nitrate. The only unsatisfactory result was that obtained with the paddy soil rich in humus. N. H. J. M.VEGETABLE PHYSIOLOGY AND AGRICULTURE. 891 Efficacy of Calcium Cyanamide under Different Conditions. 12. INAMURA (BUZZ. Coll Agr. T6Ly6 Imp. Urziv. 1906 7 53-55).- Calcium cyanamide acts more favourably in conjunction with super- phosphate than with disodium phosphate when applied to Brassica chinensis. N. H. J.

Compare Seelhorst and Nuther this vol. ii 47 ; Bartsch ibid. 481 ; Feilitzen ibid. 487; Wein ibid.).- Calcium cyanamidocarbonate is formed by passing a current of carbon dioxide through a solution of calcium cyanamide. The growth of seedlings of wheat and peas is not affected by the presence of 5 mg. of calcium or potassium cyanamidocarbonate per 100 grams of soil; but as the amounts of these salts are increased a toxic effect becomes apparent and with 20 or more mg. of the salts per 100 grams of soil the seedlings are rapidly destroyed. The rate of nitrification of the cyanamide compounds in the soil is shown t o decrease as the amounts of these are increased indicating a toxic action on the nitrifying organisms.G. Y. Manurial Value of Different Potassium Compounds for Barley and Rice. KEIJIR~ As6 (BuEZ. CoZZ. Agr. T6ky6 Imp. Univ. 1906 '7,67-72).-1n the case of barley potassium chloride accelerated flowering and increased grain production. With rice the yield was reduced. Potassium silicate gave the best results in several cases and martellin is a favourable potassium manure for graminaceous crops. Potassium sulphate is favourable to straw production whilst the carbonate was always less satisfactory when applied in conjunction with disodium phosphate. Effect of Various Potassium Manures on the Growth of Colocasia antiquorum. S. NAMIKAWA (Bull. CoZl. Agr. T6ky6 Imp. Univ. 1906 7 73-74).-The bulbs of Colocasia antiquorum (sugar- potato) are rich in starch and are extensively used as food.On a loamy soil (limed) kainite and 30 per cent. potassium salts gave equally good results somewhat better than wood-ash which is the principal potassium manure in Japan. N. He J. M. N. H. J. 35. Relation of Sodium to Potassium in Soil and Solution Cultures. JAMES F. BREAZEALE (J. Amer. Chenz. Xoc. 1906 28 1013-1025).-The plan of the experiments was to grow wheat plants for some days or weeks in a solution containing all the necessary food constituents and in similar solutions omitting sodium potassium both sodium and potassium calcium and phosphoric acid respectively. All the plants were then removed to solutions containing full nutrient and the amount of each constituent taken up from these solutions deter- mined by analysing the solutions at the end of the experiment.' The results showed that absence of any constituent in the solutions employed at the commencement resulted in an increased assimilation of the same constituent from the complete solution in which the plants892 ABSTRACTS OF CHEMICAL PAPERS. were afterwards grown. It was also found that the demand for potassium was greater when sodium was left out in the first period than when sodium was present all the time. Further experiments are described in which radishes and beet were grown first in soils which had received sodium and potassium salts respectively and then for three to six days in solutions containing full nutrient. The results obtained by analysing the solutions were similar to those in the previous experiments and showed a greater demand for potassium in the plants grown in soil which had received no potassium for some years and a diminished demand where sodium had been applied. N.H. J. M. Lime Factor for Flax and Spinach. S. NAMIKAWA (BuZZ. CoZZ. Agr. Y'ijJcyij Imp.

I n the case of spinach sand was employed with addition of the two carbonates the ratios being 1 2 1 1 2 1 and 3 1. I n both experiments the most favourable relation of calcium to magnesium was found to be 1 1. N. H. J. M. Direct Manuring of Cereals with Different Forms of Cal- cium. A. LAZZARI (Chem. Centr. 1906 ii 903-904; from Staz. sper. agmr. ital. 39 5-1 7)-Calcium hydroxide gave better results than calcium carbonate. N. H. J. ISI. Regeneration of Over-limed Soil. S. MAKI and 8. TANAKA (BuZZ. Coll. Agr. T6ky6 Imp. Univ. 1906 7 61-65).-Nakamura (this vol. ii 382) stated that a soil containing sufficient magnesium for crops but a great excess of calcium in addition is much benefited by manuring with magnesia so as to obtain a suitable ratio of CaO :&lgO. The yield of barley was increased by 60 per cent. Experiments with barley grown in sandy and loamy soils showed that over-liming may be remedied by adding magnesium sulphate and that 14 parts of the crystallised sulphato are agronomically equivalent t o 100 of magnesite.

892 ABSTRACTS OF CHEMICAL PAPERS. A n a l y t i c a l Chemistry. Measurement of Standard and Other Solutions by Means of Chemical Measures. W. SCHLOESSER and C. GRIMJI (Chenz. Zeit. 1906 30 107 1-1073).-The authors have studied the question as to whether pipettes graduated by means of water always deliver the same volume of liquid regardless of the nature of the liquid. The results obtained admit of no generalisntions. The original paper should there- fore be consulted for details. P. H,ANALYTICAL CHEMISTRY. 893 Acidimetry by Measurement of Hydrogen H. REBENSTORFF (Chem. Centr. 1906 ii 908 ; from Zeit. p/qs.-chena. Ohterr. 19 201-2 1 3).-1!tagnesium turnings are recommended for displacing hydrogen from acids the strength of which is to be determined by measurement of the volume of the displaceable hydrogen.P. H. Preparation of Sulphuric Acid of Known Strength by Specific Gravity Determinations. A. H. W. ATEN (Chem. Centr. 1906 ii 1139 ; from Clwm Jreekblad 1906 3 523-526).- The author has devised an easy method for preparing sulphuric acid of any desired strength in large quantity. For this purpose he prepares a stock solution B of such a strength that rn litres of it diluted to (6 litres give a solut.ion containing n grams of sulphuric acid per litre. The number of grams LC of water which must be added to any quantity p grams of sulphuric acid A of sp gr. 8 and per- centage strength 100a in order t o prepare the solution 3 may be calculated approximately by means of equation (i) mt.[pa/(p + x)] = a n (i) in which t is the sp. gr.of a mixture of p grams of sulphuric acid with x grams of water. Assuming that the sp. gr. of a sulphuric acid-water mixture is a linear function of its composition the equation (ii) will hold ( p + x)/t =p/S+ z (ii) ; by combining this with equation (i) the third equation nzpuS=an(p+xS) (iii) is obtained. From the latter the value of x may be calculated and hence also the percentage of sulphuric acid may be deduced. Reference t o the table gives the sp. gr. t corresponding with this strength of acid; on substituting this value of t in equation (i) x may be again determined. P. H. Variable Sensitiveness in Colorimetry. 111. DAVID W. HORN and SUE A. BLAKE (Amer. Chem. J. 1906 36 516-521. Compare this vol. ii 253 703).-Ammoniacal solutions of copper sulphate exhibit the same phenomena as those observed in the cases studied previously.The results of the investigation are tabulated and plotted as curves. The data so far obtained suggest the following generalisations. I. Equal weights of coloured solutes do not produce equal differences in colonr except when they are added to coloured solutions of equal con- centration. 11. The weight of coloured solute required to produce a perceptible difference in colour when added to a coloured solution varies greatly with the concentration of the solution and varies in an irregular manner but the general behaviour is the same in all cases and is independent of the colour under examination. I n the case of the most concentrated solutions which can be used in colorimetry the sensitiveness varies inversely as the concentration.A t a certain point of dilution this law ceases t o be valid and the weight of coloured solute required to produce a perceptible difference in colour rapidly becomes a smaller fraction of the total weight of coloured solute present attains and passes through a minimum limiting value and then rapidly becomes an increasingly larger fraction of the total solute present. All colorimetric aualyses should be made within this second range. 111. I n the case of very faintly coloured solutions the sensitiveness is much less and the percentage894 ABSTRACTS OF CHEMICAL PAPERS. error proportionately greater ; such solutions should therefore be avoided in colorimetric analysis. E. G. Analysis of Gases Rich in One or more Constituents.ALFRED STOCK and CARL NIELSEN (Ber. 1906 39 3389-3393).- Attention is drawn to the errors which may arise in the analysis of gases owing to the air contained in the absorbing liquids. This is particularly noticeable in the case of pure oxygen using either alkaline ferrotartrate or copper gauze in the presence of ammonia and ammonium carbonate. The latter reagent is better as it acts more quickly. When the freshly-prepared reagent is employed a residue of 1-03 C.C. of nitrogen is obtained from 100 c.e. of pure oxygen. If a series of determinations are conducted one after the other the amount of residue gradually decreases until after the seventh estimation it is as low as 0.11 C.C. and remains at practically this value in subsequent estimations. This value corresponds with the state of equilibrium between the air on the one side of the solution the solution and the oxygen on the other side.I n order to prevent the reagent from rapidly dissolving nitrogen the surface exposed t.0 the air may be covered with a layer of liquid paraffin. Experiments have shown that when water free from air is poured from one vessel into another by means of a funnel it rapidly absorbs gases thus 1360 C.C. of water exposed for two minutes to the air in this way absorbed 5.8 C.C. of gas. Analyses of pure oxygen made when the free side of the absorbing liquid was in contact with oxygen gave practically no residue but when this oxygen was replaced by nitrogen a residue of 0.74 per cent. of nitrogen was obtained after twenty-one hours.J. J. S. Volhard Method for the Estimation of Chlorine in Potable Waters. FRANK T. SHUTT and H. W. CHARLTON (Trans. Roy. SOC. Canada 1905 [ii] 11 (3) 67-71).-A comparison of the values of the chromate and Volhard’s methods for the estimation of chlorine in potable waters. The latter is by far the more trustworthy. G. Y. Separation of Chlorine and Bromine in Acid Solution by Hydrogen Peroxide. PAUL JANNASCH (Rer. 1906 39 3685-3659. Compare this vol. ii 194).-The solution of the mixture is placed in a glass flask fitted with a ground stopper through which pass a delivery tube a long inlet tube for passing in carbon dioxide and a dropping funnel. The delivery tube is attached to a series of four flasks each containing an ammoniacal solution of hydrazine sulphate.A mixture of concentrated sulphuric acid and water is run into the flask and then 30 C.C. of a 6 to 8 per cent. hydrogen peroxide solu- tion. Carbon dioxide is passed slowly throagh the flask which is heated by means of a water-bath quickly brought to the boil. The heating by nieans of the gently boiling water-bath is continued until the liquid in the Bask is colourless (0-5-0.75 hour). The contents of the receivers are mixed acidified with nitric acid and the hydro-ANALYTICAL CHEMISTRY. 895 bromic acid precipitated as silver bromide. The results obtained are good but usually slightly low. The most important factor appears t o be the concentration of the sulphuric acid as if this is too low only part of the bromine is driven over. J. J. S. Volumetric Estimation of Iodides in the presence of Chlorine and Bromine Ions.ERWIN RUPP and M. HORN (Arch. Pharm. 1906 244 405-411).-When the estimation is effected by adding a ferric salt and distilling 08 the iodine i t is important that ferric sulphate (iron alum) not chloride should be used. Iodides whether in the presence or in the absence of bromide or chloride or of both can be estimated without need for distillation. A weighed quantity of the sample (usually 0.2-0.5 gram) is dis- solved in about 50 c . ~ . of water in a stoppered glass bottle ; about 25 c . ~ . of dilute sulphuric acid are added then about 3 grams of solid oxalic acid and finally 1 per cent. potassium permanganate solution (usually about 10 c.c.). The mixture is allowed to remain for about three hours being shaken occasionally in order to promote the solution of the manganese peroxide that has separated; then about 1 gram of potassium iodide is added and the free iodine is titrated with N/10 thiosulphate.If an iodide is being titrated in the absence of bromide or chloride the permanganate can be added until a distinct violet colour is visible in the thin layer of liquid seen a t the top when the bottle is swung round. I n the presence of brom- ides or chlorides this guidance is not available; should decidedly less than 10 C.C. of the thiosulphate be used in the titration the result must be rejected and the estimation repeated either more of the substance or less of the permanganate solution being taken. C. F. B. The Etching Tests for Small Amounts of Fluorine.ALPHEUS G. WOODMAN and HENRY P. TALBOT (J. Arner. Chem. Xoc. 1906 28 1437-1443).-The solution is mixed with a little potassium sulphate and precipitated with barium acetate and the precipitate which con- tains also the barium fluoride is tested as usual by the well-known etching test. The authors have found that in the case of very minute quantities the method may be rendered somewhat quantitative by observing the temperature required to produce the -\-etch on the covering glass within an hour. A temperature of 79-82" dis- tinguishes between 1 25000 and 1 100000 ; of 113' between 1 100000 and 1 1000000; of 136Obetween 1 1000000 and 1 5000000; of 173-178' between 1 5000000 and 1 25000000; of 213-218O between 1 25000000 or less.

When cold the two solutions are united and the iodine liberated is titrated. One atom of iodine is liberated for every atom of fluorine present as hydro- fluoailicic or hydrofluoric acid. The results are approximately correct. L. DE K. [Fluorine in] Thermal Springs. JosB CASARES (Ber. 1906 39 Compare this VOI.ii SO),-A reply to Sahlbom and 3783-3784. Hinrichsen (this vol. ii 716 79s).

Aerxte. 1905 ii 76-77).-h sensitive reagent for oxygen is prepared by the action of phosphorus tribromide on solid copper nitrate or on a solution not con- taining more than 10 per cent. of the salt ; the mixture is then cooled and shaken with ether when it gradually becomes colourless; it can be preserved in sealed vessels. On shaking with oxygen the ether assumes a green colour and the lower layer becomes a reddish-purple; both colours however disappear after some minutes and the reagent can then be used again. The reagent can also be employed for the Gravimetric Estimation of Ozone ; Ozone Numbers of Oils.P. FENAROLI (Gazxetta 1906 36 ii 292-298).-When ozonised air or oxygen is passed through oleic acid or linseed oil contained in a simple absorption apparatus comprising five bulbs the absorption of the ozone is quantitative for wide limits of temperature (10-40”) and of velocity (up to 180 bubbles per minute) ; as the absorptive liquid loses slightly in weight a calcium chloride tube should be attached beyond the bulbs. The increase in weight of the absorption bulbs corresponds exactly with the addition of the molecule 0 for every double linking in or more exactly for every two atoms of iodine fixable by the compound employed. This absorption of ozone affords a convenient means of estimating it the results obtained being virtually identical with those yielded by the potassium iodide method.Determinations of the ozone numbers of olive maize linseed and castor oils the last two in solution in hexane from petroleum give values agreeing well with those calculated from the iodine numbers.

The funnel is filled up to a definite mark with acid which is then made to flow into the flask by turning the stopper and so creating a channel. The stopper is now put back into its original position and the funnel is filled with water which then serves as a cooling arrangement the condensed acid flowing back into the flask.

I n this manner the same quantity of sulphuric-chromic acid mixture may suffice for even six estimations. L. DE K. Sulphate and Sulphur Determinations. SALoaroN F. ACREE (J. Biol. Chern. 1906,2 135-143. Compare Folin this vol. ii 123). -Barium sulphate is readily reduced to the sulphide. If the filter paper is ignited with the sulphate the amount of sulphide is consider- able and several evaporations with concentrated sulphuric acid are necessary in order to convert the whole of the snlphide into sulphate. The strength of a solution of sulphuric or hydrochloric acid can be determined by neutralising a given weight of pure sodium hydrogen carbonate with the acid using methyl-orange as indicator evaporating the solution in a platinum vessel and weighing the sodium salt.I n titrating carbonates the acid should be run in until the pink colour corresponds with the shade of a similar volume of water saturated with carbon dioxide and containing the same amount of indicator. The strength of a solution containing pure sodium or potassium hydroxide or carbonate can be determined by adding an excess of hydrochloric acid to a known volume evaporating down and weighing the metallic chloride. Wildenstein’s volumetric method gives good results.Calcium or sulphates may be estimated by precipitation as calcium sulphate from aqueous-alcoholic solutions. J. J. S. Iodometric Estimation of Hydrazine Salts and their Use in Volumetric Analysis. ENRICO RIMINI (Atti R. Accud. Lincei 1906 Lv] 15 ii 320-325. Compare Abstr. 1904 ii 207).-The method previously given by the aiithor for estimatirg hydrazine (Zoc. cit.) may be simplified by carrying out the- reaction in an alkaline medium the change then being represented by the equation SN,H,,H,SO + 2KIO + 6KOH = 3N2 + SKI + SK,SO + 12 H20. Gssometric estima- tion by displacement of the air in a Lunge nitrometer shows that the evolution of nitrogen is rapid and complete when iodic acid is employed. I n estimating formaldehyde by Riegler’s method (Abstr. 1901,898 ABSTltACTS OF CHEMICAL PAPERS.ii 360) it is advisable to titrate the excess of hydrazine with iodate in alkaline solution since formalrzzine is not perfectly stable in an acid medium. The estimation of mercuric salts by means of hydrazine is best carried out as follows. A concentrated solution of hydrazine sulphate the strength of which need not be known is rendered neutral to methyl-orange. A known excess of seminormal sodium hydroxide is added and then the solution of the mercuric salt of which the strength is required. The solution is next heated and afterwards either made up to a certain volume and the alkalinity of an aliquot part deter- mined or filtered and the alkalinity of the filtrate and washings measured When mercuric chloride is used the reaction is expressed by N,H,,NaHSO + 2HgC1 + 5WaOH = 4NaCI + 2Hg + N + SH,O.The best method for estimating persulphates is to add to a solution of the persulphate neutral to methyl-orange first a solution of hydra- zine siilphate neutralised with potassium hydroxide and then a known volume of potassium hydroxide solution of definite titre. The liquid is then shaken and after five minutes the excess of alkali is deter- mined. The reaction is represented by the equation 2K,S20,+ N2H4,KHS0 + 5KOH = N + 5K,S04 + 5H,O. This method is sensi- tive and rapid and can be applied to ammonium salts i n the case of which Tarugi’s method (Alstr. 1903 ii 238) introduces complications. PAUL SOLTSIEN (Chem. Centr. 1906 ii 1020-1021 ; from Phavnz. Zeit. 51 765-766).-Both the di- phenylamine and the brucine reactions are interfered with by the presence of nitrous acid.When testing for nitric acid by reducing with zinc and then testing for nitrousacid the reduction should not be pushed too far as otherwise the formation of starch iodide may be prevented. I n the presence of such substances as ferric or manganic oxides the test with m-phenylenediamine should be applied. Attention is called to the presence of traces of nitrates in filter paper. T. H. P. Detection of Nitric Acid. L. DE K. Estimation of Nitrogen i n Saltpetre. W. VAN DAM (Rec. trav. chin&. 1906 [ii] 25 291-296).-D6bourdeaux’s method for the estimation of nitrogen in nitrates which is baaed on the oxidising action of nitric acid on oxalic acid in the presence of manganese sulphate (Abstr.1903 ii 573) invariably gives results which are too high owing to some of the oxalic acid undergoing oxidation by the atmospheric oxygen in the presence of the manganese sulphate ; the author finds that the method is quite satisfactory if the air of the apparatus is replaced by carbon dioxide; and that the addition of one drop of a very dilute solution of potassium nitrite to the mixture containing the nitrate accelerates the reaction which otherwise does not start for several hours when the nitrate under analysis in quite pure. M. A. W. Gravimetric Estimation of Potassium Nitrate in Meat. CARL PAAL and GUSTAV MEHRTENS (Zeit. Ncchr.

The extracts are made up to a volume of 500 c.c. of which 200 C.C. are evaporated to a volume of about 50 c.c. treated when cold with three drops of ammonia and an excess of normal lead acetate. After boiling the mixture is cooled and the precipitate collected on a filter and washed. The filtrate is acidified with acetic acid heated and the nitrate precipitated by the addition of “nitron” dissolved in acetic acid. One part of ‘‘ nitron ” nitrate is equivalent to 0.26933 part of potassium nitrate.w. P. s. Analysis of Sodium Nitrate (Chili Saltpetre). P. BECK (Zeit. and. Chem. 1906 45 669-686).-The quantity of sodium nitrate in Chili saltpetre is best estimated by Ulsch’s method (Abstr. 1891 ii 617). From the results of analyses given it is seen that the “ indirect ” method for determining the nitrate gives results which are too high; in some cases the figures are 1.5 per cent. higher than those obtained by Ulsch’s method. It is pointed out that as some samples of Chili saltpetre contain such quantities of perchlorate (compare Abstr. 1905 ii 115) as render them unfit for the manufacture of sodium nitrite the amount of sodium chloride in sodium nitrate intended for this purpose should not exceed 1 per cent. even after the sample has been fused with sodium carbonate or other substance capable of con- verting the perchlorate into chloride.w. P. s. Detection of Small Quantities of White Phosphorus in Presence of Large Quantities of Phosphorus Sesquisulphide. LOUIS ARONSTEIN (Chem. Centr. 1906 ii 977-978; from Chem. JVeekbZad 3,493-499. Compare this vol. ii 705).-Van Eyk’s lead acetate process (ibid. 358) is untrustworthy. The method of rubbing in the dark the carbon disulphide extract is sensitive up to 1.4 per cent. of phosphorus. Vignon’s method treating in a current of hydrogen and observing the green flame and also the brown coloration with silver solution may be recommended. L. DE K. Titration of Phosphoric Acid. LUDWIG SCITUCHT (Zeit. angew. Chem 1906 19 1708-1711. Compare this vol.ii 6lO).-Data are recorded which show that the estimation of free phosphoric acid in superphosphate solutions by titration with N/2 alkali and methyl- orange as indicator is considerably influenced by the dilution On addition of a large quantity of sodium chloride to a pure phosphoric acid solution the acid titre is increased. This increase is more marked if calcium dihydrogen phosphate is present in the solution and is still larger in the case of superphosphate solutions containing dissolved iron and aluminium. By taking into account the various ions in solution and applying900 ABSTRACTS OF CHEMICAL PAPERS. the law of mass action it is shown that the theoretical effect of the addition of sodium chloride is t o increase the H' dissociation of the phosphoric acid as a consequence of the diminution in the concentra- tion of H,PO,' ions.I n siiperphosphazte solutions the soluble phos- phates present diminish the I€* dissociation of the free acid and in consequence the eff'ect of the addition of sodiiim chloride is in this case more marked than in solutions of the pure acid. H. M. D. Platinum Gauze for Contact Action in Organic Ultimate Analysis. W. C. HERAEUS (Chenz. Centr. 1906 ii 907 ; from Zed. chem. Appwatenkunde 1 541-542).-The apparatus consists of a spiral coil of platinum gauze which is covered with finely-divided platinum and is encased for protection in a sheath of similar platinum gauze; i t just fills the combustion tube and exerts a powerful contact action at comparatively low temperatures.P. H. Determination of the Calorific Value of Lignite and Peat with the Lewis-Thomson Calorimeter. ROBERTO SALVA- DORI (Gccxzettcc 1906 36 ii 202-211).-The calorific value of lignite peat coke or anthracite cannot be accurately determined by the ordinary method of using the Lewis-Thomson calorimeter since these fuels are not completely burut by the mixture of potassium chlorate and nitrate employed. If however 1 part of ammonium nitrate is added t o t h e usual mixture of 3 parts of chlorate and 1 of nitrate of potassium these fuels undergo regular and ready combustion. When 2 kilos. of water are used its temperature is raised 0.54" by each gram of ammonium r i t r a t e employed. The latter salt should be fused powdered and kept for use in presence of calcium chloride.Comparative determinations were carried out with (1) the Thomson calorimeter using 1 gram of ammonium nitrate and 20 grams of the mixture of potassium chlorate and nitrate to 2 grams of the powdered fuel and (2) the calorimetric bomb of Mahler. The results obtained by the two methods were found to agree to within 5 per cent. The reaction between potassium chlorate and ammonium nitrate takes place at 123-124' according to the equation KC10,+ NH,NO = KNO + NH,ClO the ammonium chlorate formed then immediately decomposing into ammonium chloride chlorine a small proportion of oxygen nitrogen and oxides of nitrogen. To the activity of these products the ready combustion of the fuel is due. T. H. I?. Examination of Liquid Carbon Dioxide.WERDER (Chewz. Zeit. 1906 30 1021-1022).-Before taking a sample for analysis the steel cylinder containing the liquid carbon dioxide should be inverted in order to mix the contents as any air which may be contained in the cylinder would float on the carbon dioxide. A sufficiently large sample bhould be analysed so t h a t the residual gas remaining after absorption with potassium hydroxide measures at least 4 c.c.; this may require from 2 t o 4 litres. The gas should be measured out in successive portions of 200 c.c. each oneANALYTICAL CHEMISTRY. 901 being passed into the potassium hydroxide burette and absorbed before introducing the next. The following are suggested to be the require- ments of liquid carbon dioxide it should not have a pungent odour and should have a purely acid taste ; it should contain at least 98 per cent.of carbon dioxide but not more than 0.5 per cent. of carbon monoxide ; it should not contain any sulphurous or nitrous acids and should not decolorise acid permanganate when bubbled through this solution for a quarter of an hour nor should it produce a precipitate when bubbled through a solution of silver nitrate acidified with nitric acid. P. H. Estimation of Carbon Dioxide. H. REBENSTORFF (Chem. Zed. 1906,30 1114-1115).-The apparatus described by the author (this vol. ii 487) when filled with sodium nitrate solution of sp. gr. 1.35 can be employed for estimating carbon dioxide. The carbon dioxide in the generating apparatus is displaced by means of hydrogen produced by adding a known weight of magnesium to the acid; the volume of carbon dioxide is obtained by deducting the volume of hydrogen so evolved from the total volume of gas collected.P. H. Analysis of Hydrofluosilicic Acid. LUDWIG SCHUCHT and W. MOLLER (Bey. 1906 39; 3693-3696. Compare Sahlbom and Hinrichsen this vol. ii 798).-According to Offermann hydrofluosilicic acid may be titrated with cochineal as indicator according to the equation H,SiF + 6KOH = 6KF + H4Si04 + 2H,O and according to Weise with phenolphthalein as indicator according to the equation H,SiF + 2KOH = K,SiF + 2H,O. The reverse is however the case since the action with cochineal is represented by the latter equation and that with phenolphthalein by the former When cochineal is used the end point is not sharp. When Phenolphthalein is used the titration must be conducted with hot solutions. If an excess of neutral calcium chloride is added to the solution of hydrofluosilicic acid the end point is sharp when the titration is conducted with sodium hydroxide with methyl-orange as indicator.The action is represented by the equation H,SiF + 3CaC1 + 6NaOH = 3CaF + 6NaC1+ H,SiO + 2H,O.

BORIS GLASSMANN (Ber. 1906 39 3368-3369).-To a neutral or faintly acid solution of the glucinum salt a mixture of equal parts of 25 per cent.potassium iodide and saturated potassium iodate solution is added after five minutes the iodine which has separated is decolorised by 20 per cent. sodium thiosulphat e and a small quantity more of the iodine-iodate mixture added. The solution is then heated on the water-bath for half an hour and the colourless flocculent precipitate of glucinum hydroxide filtered washed with hot water dried and ignited. Volumetric Estimation of Mercury. ERWIN RUPP (Ber. 1906 39 3702-3704. Compare Rupp and Krauss Abstr. 1902 ii 475). -A modification of the author’s earlier method (Abstr. 1905 ii 484). The mercury solution (25-50 c.c. which should contain about 0.2 gram of the metal) is mixed with potassium iodide until the pre- cipitate first formed is redissolved; it is then made alkaline with an alkali hydroxide and shaken vigorously while 2-3 C.C.of pure formaldehyde and 10 C.C. of water are added ; after 30-60 seconds it is strongly acidified with acetic acid and the estimation carried out as described previously (Zoc. cit.). Mercurous salts must first be converted into mercuric salts by the addition either of bromine or of permanganate. A. McK. Insolubility of Ferric Hydroxide in Ammoniacal Solutions. GREGORY P.

The mass is dissolved in water and precipitated while boiling with excess of sodium carbonate. The Precipitate is freed from uranium by redissolving in sulphuric acid and reprecipitat ing with sodium carbonate. The combined filtrates are heated to boiling and after adding 0.5 gram of ammonium phos- phate a slight excess of ammonia is added. After boiling for a few minutes longer the precipitate is collected and washed with a weak solution of ammonium sulphate.The filtrate which contains the vanadium is acidified with sulphuric acid reduced with sulphur dioxide and after boiling off the excess of the latter titrated with permanganate.

Microscopic Examination of Starch and Detection of Rice Starch in Wheat Starch. EUGBNE COLLIN (J. Pharz. Chim. 1906 [ vi] 24 385-395).-~Iicroscopically wheat-starch is composed of small round or oval granules and large lenticular granules either isolated or aggregated in groups of granules of unequal size.The aluerone grains which do not stain blue are aggregated in granules of equal size. The irregular masses of gluten are also characteristic. Rice starch consists of simple granules hometimes showing a hilum of corn- plicated oval granules and of meal-like masses of cells. It contains rela- tively few aluerone granules and the gluten behaves differently to that of wheat. To detect rice-starch in wheat 33.33 grams of flour are made into a ball with 17 grams of water and worked between the fingers in a fine stream of water over a fine-meshed sieve. The starch and waste water are well shaken and set aside for twelve hours in a large conical flask when the starch separates in three well-marked layers which can be separated by decantation.The top layer contains most of the small starch granules and the bottom layer the largest grains whereas the middle layer is mainly composed of the cellulose and proteid element of the flour ; when rice starch is present it is almost entirely deposited in this layer and its presence can be detected in so small a proportion as 1 per cent. E. F. A. Estimation of Cellulose Lignin and Cutin in Crude Fibre. JOSEF K ~ N I G (Zed. Ncchr.

The residue remaining after this treatment is collected on an asbestos filter and washed. Both residue and filter are now subjected to the action of ammoniacal cupric oxide solution for two hours. The mixture is then gently warmed and the residue collected on an asbestos filter washed dried at llOo and weighed. The filter and its contents are next ignited and again weighed. The loss in weight gives the amount of cutin present. The ammoniacal filtrate from the cutin residue is mixed with 300 C.C. of 80 per cent. alcohol906 ABSTRACTS OF CHEMICAL PAPERS. and well stirred; the dissolved cellulose is reprecipitated and is collected on an asbestos filter dried at llOo weighed ignited and the filter reweighed.The difference between t,he total crude fibre and the sum of the‘cutin and the cellulose gives the quantity of lignin w.

The depth of colour increases with the amount of casein present. and is therefore not a trustworthy test for pectins. L. DE K. J. J. S. Presence of Formaldehyde in certain Food-Stuffs. GUSTAVE PERRIER (Compt. rend. 1906 143 600-602).-By means of the sensi tive colour reaction for formaldehyde described by Voisenet (this vol. ii 59) the author has found that the amount of this compound present in cider and various smoked foods varies from 0.04 mg. to 3.6 mg. per 100 grams. I n view of this fact and the facts that formaldehyde is present in air (Henriet Abstr.1904 i 648; ii 598) and in products of combustion (Trillat Abstr. 1905 ii 53 325 ; t h i s vol. i 234) it is urged that the present (French) laws and regulations inhibiting absolutely the use of formaldehyde as a food preservative should be revised. EDWARD MACKAY CHACE (J. Amer. Chem.

About 50 C.C. of fhe concentrated solution are cooled rendered slightly alkaline with potassium hydroxide and treated with a few drops of 20 per cent. solution of potassium acetate and about 10 C.C. of 30-40 per cent. solution of calcium chloride. The mixture is stirred rapidly for a minute or two and left a t the ordinary temperature for twelve to fifteen hours when if tartaric acid is present characteristic crystals of calcium tartrate are produced. A study has been made of the effect on this test of the presence of citric malic succinic oxalic and aconitic acids and it is found that in most cases the method is trustworthy.The presence of alum or excess of mineral acids however prevents the formation of the precipitate. The test is recommended especially for the detection of tartaric acid in wines ciders and fruit syrups. E. G. Determination of the Saponiflcation Number in Oils and Fats. J. DAVIDSOHN and G. WEBER ( C h e m . Centr 1906 ii 1141 ; from Xeifeensiedersxeit. 33 770-771).-0ne or two grams of the sample are dissolved in a little ether 10 C.C. of 3N-potassium hydroxide and 25 C.C. of absolute alcohol are added and the whole is boiled for fifteen minutes in a reflux apparatus. The solution is then titrated back with iV-hydrochloric acid using phenolphthalein as indicator.L DE K. A Method of Estimating Urea. H. D. HASKINS (J. Biol. Chem. 1906 2 243-249).-A modification of the Morner-Folin method. W. D. H. N. MONTI (Gaxxetta 1906 36 ii 477-480).-The greyish-violet coloration obtained by evaporating aconitine on the water-bath with sulphuric or phosphoric acid is due to the presence of impurities in the alkaloid and up to the present no reaction has been given for aconitine which is not obtained with other alkaloids. The following reaction detects 0.0001 gram of aconitine for which it is specific if applied to sufficiently pure products of an alkaloidal nature. A small portion of the alkaloid (0~0002-WOOl gram) is placed in a porcelain capsule and treated with 2 to 4 drops of sul- phuric acid of sp.gr. 1.75-1-76. If only aconitine is present either no change or a faint yellow coloration is produced on heating the capsule for five to six minutes on a water-bath ; but if a quantity of crystallised resorcinol about equal to that of the alkaloid taken is added and the heating continued the liquid assumes a reddish-yellow colour which gradually changes to a n intense reddish-violet ; this colour is very stable and persists for a long time if the capsule is kept in a desiccator. New Reaction of Aconitine. T. H. P,ANALYTICAL CHEMISTRY. 909 [Volumetric J Assay of Cinchona Barks. AUALBERT PANCHAUD (Chem. Cent?.. 1906 ii 1212 ; from Xchweix. JVoch. Phavna. 44 580-582).-The author observed that a chloroform solution of cin- chona alkaloids rapidly becomes neutralired owing probably to the following reaction taking place CHCl + 0 = COCI + HCI.If it is intecded to determine the alkaloids by titration the chloro- form should therefore a t once be evaporated off. L. DE K. Alkaloid Reactions [Codeine]. C. REICHARD (Chem. Centv. 1906 ii 1220-1221 ; from Pharm. Centr.-HcclZe 47 727-'733).- A colourless crystal of codeine gives no colour with strong sulphuric acid. I n contact with 30 per cent. nitric acid the latter turns yellow. Twenty-five per cent. hydrochloric acid is not affected. With bismuth chloride a dark yellow colour is produced ; on adding aqueous potass- ium hydroxide a reddish-brown precipitate is formed. A mixt.ure of codeine and sodium arsenate turns gradually dark grey a t the edges when heated with hydrochloric acid ; on further addition of sulphuric acid a yellow or greenish-yellow colour is generated.A mixture of codeine and ammonium molybdate with a drop of hydrochloric acid turns first yellow afterwards blue. A mixture of codeine and a-naphthol gives no reaction with aqueous patassium hydroxide or hydrochloric acid but on adding sulphuric acid a blue coloration is noticed which increases on warming. A mixture of codeine and sodium iodate turns yellow on adding 25 per cent hydrochloric acid. When a mixture of codeine and ammonium metavanadate is moistened with water and then dried it turns bright yellow round the edges. If a mixture of crystals of codeine and mercurous nitrate is moistened with water the codeine crystals turn dark grey and then turn reddish-brown on adding a drop of sulphuric acid. Several other reactions of less importance are given.L. DE K. Estimation of the Alkaloids in the Leaves and Stalks of Datura Arborea. HEINRICH BECKURTS (Chem. Centr. 1906 ii 916 ; from Apoth. Zeit. 21 662).-Ten grams of the dried and powdered leaves or stalks are shaken with 90 grams of ether and 30 grams of chloroform 10 C.C. of a 10 per cent. solution of sodium hydroxide are added and the whole set aside for three hours with frequent shaking. Sufficient water is then added to make the powder form a coherent mass and after the lapse of an hour 60 grams ( = 5 grams of sample) are poured off and filtered t'hrough a dry filter. Of the filtrabe one-half is distilled to expel any ammonia and the remaining liquid is shaken in a separating funnel with 10 C.C.of N/100 hydrochloric acid and then titrated back with N/100 potassium hydroxide using iodoeosin as an indicator. The leaves contain on an average 0.444 gnd the stalks 0.826 per cent. of scopolamine. L. DE K. Alkaloid Reactions (Thebaine). C. REICHARD (Chem. Centr. 1906 ii 915-916 ; from Phccrm. Centr.-HaZZe 1906 47 623-629).-A small quantity of thebaine when treated with one drop of concentrated sulphuric acid turns brownish-yellow and then pure yellow. When910 ABSTRACTS OF CHEMICAL PAPERS. moistened with 25 to 30 per cent. nitric acid thebaine slowly turns yellow and as the colour darkens streaks are developed through the liquid. Concentrated hydrochloric acid likewise produces a yellow colora- tion with green streaks.A mixture of thebaine with copper sulphate is turned permanently green by 25 per cent. hydrochloric acid whilst a mixture with mercuric chloride turns yellow and then grey. Thebaine may be distinguished from narcotine narceine or papaverine by the black coloration which is developed after half an hour on moistening a mixture of the alkaloid with mercurous nitrate. Thebaine when evaporated to dryness with stannous chloride and moistened with 40 per cent. potassium hydroxide turns black or greenish-black; when treated in the same way with antimony chloride aud potassium hydroxide it tourns yellow. When treated with a concen- trated hydrochloric acid solution of bismuth chloride it gives a yellow coloration which is changed to reddish-brown by the addition of potass- ium hydroxide.A few drops of concentrated cobalt nitrate solution when warmed with thebaine gives a brown residue. A mixture of thebaine with diphenylamine treated with one drop of concentrated sulphuric acid turns dark reddish-brown and after some time green whereas codeine under the same conditions remains colourless. A mixture of thebaine with a-nitroso-P-naphthol turns light green on addition of one drop of 25 per cent. hydrochloric acid ; on evaporating to dryness the colour changes to violet. P. H. Separation of Indole from Scatole and their Estimation. CHRISTIAN A. HEI~TER and M. LOUISE FOSTER (J Biol. Chern. 1906 2 267-271).-From a solution containing both substances the indole can be completely removed as a naphthaquinone compound and the scatole can then be distilled and recognised by Ehrlich’s dimethylsmino- benzaldehyde react ion.The estimations are colorimetric. W. D. H. Analysis of Indigo. EDMUND KNECHT ( J . Soc. Byem Colourists 1906 22 330-332 ; a reply to Bloxam. Compare this vol. ii 818 819 820).-l’he author records the results of experiments which show that his method of titrating indigo with titanous chloride (Abstr. 1905 ii 872) is quite trustworthy. The concentration of the indigo solution and the strength of the titanous chloride solution within reasonable l i m i t s have no influence on the results obtained. w. P. s. Detection of Indican in Urine by means of Alkali Per- sulphates. LUCIANO Rossr (Rend. Accad. Sci. Pis. Mut. Nupoli 1906 [iii] 12 309-311).-A solution of an alkali persulphate is a very sensitive reagent for indican in urine but i t must be used in small amount otherwise no coloration may be obtained when indican is present.The best method of carryiDg out the test is to add to 5 or 6 C.C. of the urine an equal volume of concentrated hydrochloric acid and one drop of 10 per cent. potassium (or sodium or ammonium) per- sulphate solution The formation of a violet-blue coloration which when ammonium persulphate is used appears immediately indicates the presence of indican. If 1 or 2 C.C. of chloroform are added to the tube and the latter closed with the thumb and gently inverted two orANALYTICAL CHEMISTRY. 911 three times the chloroform assumes a more or less intensely blue coloration according to the amount of indican present. This method may also be applied to the estimation of indican by Wang’s process.T. H. P. Behaviour of Nessler’s Reagent towards sonie Glucosides [ Saponin] and Carbohydrates. LEOPOLD ROSENTHALER (Che7n. C‘entr. 1906 ii 7174 ; from Phaivn. Centr.-l€uZZe 47 58l).-In the cold Nessler’s reagent gives no reddish-yellow precipitate with the saponin from sarsaparilla and but slowly a dirty green precipitate with that from guaiacum. The precipitates formed on heating are the same for all saponins except that of sarsaparilla which is but slowly acted on even on boiling. Salicin gives with Nessler’s reagent in the cold a yellow crystalline precipitate which scarcely changes its colour on warming. Amygdalin gives off ammonia which then colours the reagent whilst with other glucosicles the carbohydrate group gives a reaction.Dextrose lsvulose xylose maltose also lactose (slowly) reduce the solution and the yellowish-red precipitate soon becomes dark red and finally green and greyish. Sucrose also gives reduction on boiling. L. DE K. Qualitative Analysis of Tannins. ~IAXIMILIAX NIERENSTEIN (Chem. Zeit. 1906 30 86S).-The solution is mixed in the cold drop by drop with a one-half per cent. solution of diazobenzene chlllride. Tannins belonging to the catechol group a t once give a precipitate whilst those belonging to the pyrogallol group do not (compare this vol. i 446). L. DE K. Estiniation of Tannin. BOUDET (Bull. SOC. chiv2. 1906 [iii] 35 760-762).-This is a modification of the iodometric method devised by Jean (Abstr. 1900 ii 632).Four grams of iodine and 8 grams of potassium iodide are dissolved in water and the solution made up to 1 litre. The solution of sodium thiosulphate employed contains 7.81 grams of the salt per litre. Each gram of iodine used is eqniva- lent to 1.137 grams of tannin. I n carrying out the estimation 4-54 grams (4 x 1.1 37) of the tanning material are exhausted with boiling water and the extract after filtration is made up to 1 litre. To 10 C.C. of this solution a like quantity of the iodine solution is added and the mixture set aside for two hours. At the end of that time the excess of iodine is estimated by means of the sodium thioeulphate solution using starch mucilage as an indicator. The quantity of iodine used expressed in tenths of a c.c. is equal to the percentage of tannin in the tanning material.The method is applicable to the estimation of tannin in cutch the end of the reaction being marked in this case by the liquid under titration becoming transparent. Gallic acid may also be estimated by this process; 1 gram of iodine being equivalent to 0,467 gram of gallic acid so that in prepar- ing solutions for estimation 0.467 x 4 grams of the crude material should be taken. I n eatimatiug tannin and gallic acid in products containing both,912 ABSTKACTS OF CHEMICAL PAPERS. 10 C.C. of a solution prepared as for the estimation of tannin is titrated in the usual way and the number of tenths of a C.C. of iodine solution used (T+ G ) noted. To a second 10 c.c. 1 gram of hide powder is added the mixture is set aside for twelve hours filtered and the filtrate treated with iodine solution titrated and the number of tenths of a C.C. of iodine solution used (G,) noted.The percentage of tannin present is equal to T+ G - G and that of gallic acid is given by G x 0.041. T. A. H. Rapid Estimation of Albumin in Urine GEORG BUCHNER (Chem. Centr. 1906 ii 717 ; from Munc?b. med. Woch. 53 1019-1020).-The urine is boiled in a specially graduated tube a little brine is added and a few drops of nitric acid. After one hour the volume of the coagulated albumin is read off. L. DE K. Means for Distinguishing True Albumin I in Urine f'rom Mucinoid Substances. LEON GRIMBERT and EMILE DUFAU (J. Ylmrrn. China. 1906 [ vi] 24 193-199).-The usual Heller (nitric) ring test is applied and also a second test substituting syrupy citric acid for nitric acid. (1) If the urine contains mucinoids only a more or less decided ring is formed with citric acid a t the place of contact within one or two minutes and often the whole of the supernatant urine becomes turbid; with nitric acid however no ring is visible at the place of contact but a nebulous ring is formed a little above this. (2) If the urine contains pathological albumin only no ring whatever is obtained with citric acid but with nitric acid a ring is formed at the place of contact. (3) If the urine contains both mucinoids and albumin reactions are obtained with both citric and nitric acids. These preliminary tests render it impossible to mistake mucinoids for albumin. L. DE K. Estimation of Proteid-Nitrogen contained in Beet-Molmses. ALBERT STUTZER and J. E. TON WOLOSEWICZ (Zeit. anal. Chem. 1906 43 614-620).-Good approximate results may be obtained by dis- solving 50 grams of the molasses in 300 c . ~ . of water and diluting the filtrate to 500 c.c. 100 C.C. are faintly acidified with alumsolution and then mixed with 25 C.C. of Stutzer's cupric hydroxide emulsion and 100 C.C. of water. After five hours the deposit is collected and the nitrogen determiired by the Kjeldnhl process. There is as yet no satisfactory process for the separate determination of peptones and albumins in molasses. L. DE K. Estimation of Proteid in Human Milk. ALFRED W. SIKES (J. PI~ysioZ. 1906 34 481-489).-Hot alcohol precipitates the proteids of human milk completely and extracts the non-proteid con- stituents entirely. The addition of a small quantity of citric acid prevents any precipitation of salts. The precipitate is best washed by the use of the centrifuge; drying occurs rapidly and the proteid is weighed directly. The percentage of proteid varies from 1.66 to 2.68. W. D. H.

921 Organic Chemistry. Alkaline Aqueous Mercuri-iodide as a Reagent for Hydroxyl Groups. LEOPOLD ROSENTHALER (Arch. Pharm. 1906,244,373-375). -When boiled for one minute with Nessler's solution substances which contain a primary or a secondary alcohol group bring about a reduction of the solution (to metallic mercury). Substances containing a tertiary alcoholic group do not effect this reduction The action of substances containing phenolic groups is varied Sachsse's (alkaline mercuri-iodide) solution reacts in the same way but not Knapp's (alkaline mercuricyanide) solution. C. E. B. Preparation of Chemically Pure Methyl and Ethyl Alcohols ; their Specific Gravities. PETER KLASON and EVERT NORLIN (ArlEiv Kern. Mirz. Geol. 1906 2 No. 24 1-7).-Chemically pure methyl or ethyl alcohol may be prepared as follows 500 grams of pure potassium methyl (or ethyl) sulphate are dissolved in water and to the solution rather more than the calculated quantity of pure sulphuric acid is added the whole liquid measuring about 2 litres.The methyl (or ethyl) alcohol is distilled in a current of steam and concentrated by fractionation finally from ignited potassium hydroxide. To remove the last traces of moisture freshly ignited lime (from marble) and finally calcium are used. Distillation from calcium is continued until the specific gravity of the alcohol undergoes no further change. Pure methyl alcohol has the sp. gr. 0.796472 a t 15'/15' and between 0' and 30° the sp. gr. at t0/40 is expressed by 0.80999 -0*00093 t Pure ethyl alcohol has the sp.gr. 0.794130 at 15'/15O; the value 0.79429 on which Windisch's tables are calculated indicates that the alcohol used by this author contained 0.06 per cent. of water. Its sp. gr. a t O'j4" is 0,80628 ; at 1Oo/4O 0.79792 ; at 2Oo/4O 0.78938 ; at 30°/4' 0*78080. These values agree well with those obtained by Win kler . - 0.00000025 t2. T. H. P. sec.- and tert. -Pinacolyl Alcohols and their Separation MAURICE DELACRE (Bull. Xoc. chim. 1906 [iii] 35 811-816. Compare this vol. i 476 518 551 784).-tert.-Pinacolyl alcohol was obtained by the application of the Grignard reaction to isopropyl bromide. Its odour is similar to that of the alcohol prepared from pinacolin and after the removal of traces of impurity by shaking it with solid potassium hydroxide it boils at 118*4-119*2° under 748 mm.pressure and freezes about 10.5O. The chloride boils from 112-113*4° and solidifies a t 7'; the acetate obtained by warming the alcohol with acetic anhydride for several hours boils from 125-140". When the alcohol is heated with the anhydride in a closed tube for three days at 200". the principal product is tetramethylethylene VOL. xc. i. 3 r922 ABSTRACTS OF CHEMICAL PAPERS. (py-dimethyl-Ap-butylene). The tert.-pinacolyl alcohol (and also the alcohol regenerated from the acetate described above) is dehydrated by dilute sulphuric acid much more rapidly than the alcohol obtained from pinacolin and this method may be used for their separation. The synthetic tert.-pinacolyl alcohol and the alcohol obtained from pinacolin appear therefore to be distinct substances possessing different physical properties but yielding the same derivatives (chloride bromide acetate).The formation of the same derivatives from the two alcohols is similar to the transformation of the group CMe,'CH:CH into CMe,:CMe by the action of hydrogen bromide on yy-dimethyl- ha-butylene (this vol. i 477). T. A . H. Succinic Pinacone [&-Dimethylbexane-P~-diol] OH*CMe,*CH,*CH,*CMe,*OH. LOUIS HENRY (Compt. rend. 1906 143 496-50O).-P~-Dimethjl- hexane-pr-diol (compare Zelinsky Abstr. 1902 i 593 ; and Valeur BUZZ. Xoc. chim. 1903 27 1139) readily obtained by the action of magnesium methyl bromide on ethyl laevulate behaves like a tertiary alcohol (this vol. i 133 329) and reacts with fuming hydrochloric acid or acetyl chloride to form Pc-dichloro-/3c-dimethylhexane CMe,Cl*CH,*CH,*CMe,Cl which crystallises in plates or needles melting a t 66-67' boils and decomposes a t 180' and is identical with the compound obtained by the action of hydrochloric acid on diisocrotonyl or diisobutenyl (Pogorzelsky Abstr.1899 i 785). Pe-Dimethylhexane-&diol is readily dehydrated by the action of dilute sulphuric acid even in the cold to form s-tetramethyltetramethylene oxide yH2*CMe2>0 (corn- CH2*CMe2 pare Pogorielsky Abstr. 1899 i 785) which is a colourless mobile liquid with an agreeable odour boils at 116-117" and reacts even in the cold with fuming hydrochloric acid to form PE-dichloro-@-dimethyl- hexane. When /3r-dimethylhexane-Pediol is distilled it suffers partial dehydration and forms the unsaturated alcohol CMe,:CH*CH,*CMe,*OH [P~-dimethyZ-A~-hex~Zene-P-oZ] which is a colourless mobile liquid with an agreeable penetrating odour boils a t 165' combines readily with bromine and is converted into its chZoricZe by the action of acetyl chloride.31. A. W. Distillation of Ether. E. J. SWAAB (Chm. Centr. 1906 ii 841 ; from Pharm. WeekbZad 1906 43 817-818).-A glass attachment is described enabling a reflux condenser to be used the condensed ether passing down a vertical tube into the receiver the vapour entering by means of a side branch. P. H. Freezing and Melting Points of Glyceryl Nitrate. HERMANN KAST (Chem. Centr. 1906 ii 948 ; from Zeit. ges. Xcldess Sprengstof- wesen 1 225-228).-Glyceryl nitrate exists in two modifications. The labile form melts a t 2.8-2.9' and solidifies a t 2*0-2*2O whilst the stable form melts at 13*1-13*2' and solidifies a t 12.5'.The labileORGANIC CHEMISTRY. 923 form has a more glassy appearance than the other. It is very difficult to freeze small quantities but less so to freeze largequantities of glyceryl nitrate; in a mixture of ether and carbon dioxide it solidifies to an amorphous mass which however becomes liquid on warming to temperatures below the true freezing point; when once it has been frozen it is less difficult to freeze it a second time. The depression of the freezing point of glyceryl nitrate-by dinitrochlorohydrin agrees fairly closely with Kaoult's law. P. H. Origin of Optically Active Fatty Acids in Nature. CARL NEUBERG (Chem. Centr. 1906 ii 1133-1133 ; from Biochem.Zed. 1906 1 36S-379).-The author has obtained experimental evidence in support of his theory that mineral oil originates from the optically active decomposition products of proteids. The fatty acids isolated from a sample of putrid cheese yielded a fraction comprising from acetic to hexoic acid which had a + 1.3". The volatile acids obtained from putrid gelatin were similarly active but to a less degree. Further by the action of lipase from vegetable sources on the triglyceride of dibromostearic acid free dextrorotatory dibromostearic acid and a dextrorotatory glyceride were obtained showing that as a result of slow oxidation and asymmetric fission by living or unorganised ferments inactive fats may give rise to optically active substances.

Compme Abstr. 1901 i 63 ; Warburg and Fischer Abstr. 1905 i 698).-The resolution of the inactive acid can be effected withouc great loss of material by a method involving fractional crystallisation of the cinchonine salt and "freezing" out the inactive acid from the active acids so obtained. A supersaturated solution of the salt C,9H,,0N,,2C,H,0,Br is made by dissolving 153 grams of the acid and 148 grams of cinchonine in 3 litres of water a t 30-35' the last 25 per cent. of the acid being added slowly after the base has dissolved. After evaporating the solution at 27-30' in a vacuum to 2,300 c.c. the crystals (fraction I.) are removed and the mother liquor evaporated to about 1,400 C.C.and the second crop of crystals (fraction 11.) filtered off. The solution of these crystals is employed in dissolving a fresh quantity of cinchonine and of the racemic acid The acid from fraction I. (a - 11') and that from the mother liquor from fraction 11.

JULIUS MARCUSSON (Ber. 1906 39 3466-3474).-According to Lewkomitsch (Proc. 1899 15 190) incompletely hydrolysed fats should contain mono- and di-glycerides and the presence of these substances should be indicated by a high acetyl value ; but as other compounds such as hydroxy-acids lactones &c. are also indicated by the acetyl value the author has endeavoured to isolate the lower glycerides and thus obtain further support for the theory of successive hydrolysis. A quantity of incompletely saponified fat was divided into two equal parts. One was acidified and the precipitated neutral fat and free fatty acid acetylated directly; from the other portion after removing excess of alkali with acid the soaps were extracted and the residual neutral fat acetglated.Finally the fatty acids from the soaps of the second portion were acetylated. The anticipated increase in the acetyl value was never observed. The portion containing both neutral fat and free fatty acid usually gave a slightly higher acetyl value than that of the neutral fat and the acetyl value of the separated acids were sometimes as high as and sometimes higher than that of the neutral fat. These results do not point to the existence of the lower glycerides but seem to depend on certain changes which have occurred in the fatty acids. The saponification of olive oil by shaking with concentrated aqueous sodium hydroxide in stoppered vessels excludes the inter- ference of atmospheric oxygen and affords scope for the hydrolysis to occur in successive stages but no indication of the formation of the lower glycerides was obtained.Saponification of this oil in the cold with the enzyme of castor oil seeds gave no indication of successive hydrolysis The hydrolytic changes which occur in rancid fats do not give rise to the lower glycerides for although dierucein is found in old rape-seed oil,. yet it only occurs in the oil which has been refined with sulphuric acid and in all probability arises as a fission product of trierucein formed not by alkaline hydrolysis but by the action of the acid. The examination of rancid sheep's tallow and olive oil gave no indubitable evidence of the presence of mono- and di-glycerides.G. T. M. Beeswax from Annam. J. BELLIER (Ann.

With potassium carbonate the action proceeds further and in addition to the alcohol some pinacolin and diisopropenyl are formed.

When ethyl methylacrylate reacts with magnesium methyl iodide dimethylisopropenylcarbinol diisopropenyl and aa-met?~~lethylacetone [methyl a-methyZpropyZ ketone] are produced (compare Kohler Abstr.1904 i 595). aa-Methylethylacetone may also be prepared by treat- ing ethyl acetoacetate with ethyl and methyl iodides successively in presence of sodium and alcohol and hydrolysing the complex ester so formed. The ketone is liquid has a penetrating camphoraceous odonr and boils at 116" under atmospheric pressure ; the semicarbaxone crys- tallises from ether. and melts a t 95-96'; the oxime is a pungent smelling liquid and boils at 89' under 20 mm. pressure ; the phenyl- hydrazone is viscid and boils at 152' under 10 mm. pressure.

This ketone may be $-butylacetone CMe,=CH,*C@Me. Attempts to synthesise $-butylacetone by condens- ing tert.-butyl chloride with trioxymethylene in presence of magnesium yielded only Tissier's alcohol CMe,*CH,*OH. The iodide prepared from the latter by condensation with acetyl chloride in presence of zinc yielded only traces of the ketone sought and similarly attempts t o prepare the ketone from ethylacetoacetate were unsuccessful.Dimethylisobutenylcarbinol CMe,:CH*CMe,*OII is the principal product of the interaction of rnngnesium methyl iodide and ethyl methylacrylate. It ha5 a camphoraceous odour and boils at 138' under atmospheric pressure (compare von Fellenberg Abstr. 1904,ORGANIC CHEMISTRY. 927 i 961).

The foregoing results show that the fixation of magnesium alkyl haloids by the up-unsaturated esters of the aliphatic series is confined to magnesium methyl iodide and in this respect differ from those obtained by Kohler (Abstr. 1904 i 595) and by Kohler and Heritage (Abstr.1905 i 207) with unsaturated cornpounds of the cyclic series.

Chem. 1906 57 1-46).-When an alkaline solution of dextrose is kept at a temperature rather above the ordinary slow decomposition takes place and the solution assumes a yellow or brown colour.If hydrogen peroxide has been added t o the solution in suffivient quantity no coloration is observed even after the lapse of weeks; should there cease to be excess of hydrogen peroxide the brown colour appears but it can be destroyed if a little of the peroxide is added immediately after its appearance. It is shown that the brown colour is due to the action of alkali on acetaldehyde which is produced in the decomposition of the sugar and the preventive effect of the hydrogen peroxide consists in removing the acetaldehyde932 ABSTRACTS OF CHEMICAL PAPERS. by oxidation to acetic acid. This view is in harmony also with experi- ments by Framm (Abstr. 1897 i 5 ) and others by the author which show that the production of the brown colour may be prevented also by (1) working under diminished pressure and so removing the volatile aldehyde (2) passing a rapid current of oxygen hydrogen or nitrogen through the solution or (3) adding ammonia sodium hydrogen sulphite or potassium cyanide-substances which fix the aldehyde. When such means are used to prevent the formation of a brown colour the two products of the slow decomposition of the sugar (dextrose or laevulose) under the influence of alkali are formic acid and acet- aldehyde.Other substances for example lactic acid may be pro- duced but to an extent which is negligible so far as the main character of the decomposition is concerned. For every molecule of sugar decomposed two molecules of formic acid are produced and it has further been shown in a less direct manner that for every molecule of sugar decomposed two molecules of acetaldehyde are produced.Thus the decomposition may be repre- sented by the equation C6HlzO6 = 2CH,*CHO + 2H*CO,H. Galactose and mannose although but few experiments have been made with them appear to undergo a similar decomposition. The substances which were found to promote the sugar decomposition in question were potassium and sodium hydroxides potassium sodium and lithium carbonates and disodium hydrogen phosphate. The decomposition is thus a catalysis by the OH’ ion and the velocity of decomposition is proportional to the concentration of that ion. When a solution of sodium formate slightly acidified with acetic acid and containing some finely-divided rhodium (‘I rhodium black ”) in suspension is warmed under a reflux condenser decomposition into carbon dioxide and hydrogen readily takes place.If however an amount of acetaldehyde equivalent to the sodium formate is distilled into the sodium formate solution while the latter is being heated a yield of 60-70 per cent. of ethyl alcohol is obtained. That is acet- aldehyde and formic acid have reacted under the influence of a catalytic agent to form ethyl alcohol and carbon dioxide. Hence ethyl alcohol and carbon dioxide may be obtained from sugars by a purely chemical decomposition and the change involved in fermentation may be realised without the intervention of enzymes. The equation C,H,,06 = 2CH,*CHO + 2H*CO,H must not be regarded as excluding the possible Formation of intermediate products and in fact it is extremely probable that such are formed. Lactic acid is especially referred to in this connexion and it is pointed out that although only traces of this acid were found in the author’s experi- ments yet when the alkali concentration is high and the solutions are brown in colour considerable quantities are produced.It seems that the decomposition of the sugar (probably through some unknown intermediate product) takes place preferentially into aldehyde and formic acid but that when this mode of decomposition is checked possibly through accumulation of the decomposition products other reactions take place ; so for example in solutions containing a large quantity of hydroxyl ions lactic acid is one of the chief products,933 ORGANIC CHEMISTRY.The following scheme represents diagrammatically the various possible courses of the sugar decomposition Dextrose Fructose 2 Mannose Intermediate product I .c. c \ Lactic acid J.

An enzyme is in fact only a catalytic agent of a special kind. The Liquefaction of Starch Powder and Starch Grains. A. BOIDIN (Compt. rend. 1906 143 511-512).-Prior to Fernbach and Wolfe (this vol.i 804) the author has shown that potassium hydrogen phosphate prevents the liquefaction of starch paste (compare Abstr. 1904 ii 816) and in the present paper it is shown that whilst magnesium phosphate has a similar action calcium phosphate does not render starch viscous and if a solution of purified starch powder is heated in the presence of calcium sulphate or phosphate it is saccharified to the extent of 33 per cent. Further if the alkali hydrogen phosphates present in the starch granules are converted into calcium phosphate by the addition of calcium chloride or into the corresponding di-hydrogen phosphate by the addition of acid the solution obtained by boiling the starch grains is limpid and mobile and readily saccharified. J.C. P. M. A. W. Preparation of Methylamine from Ammonia and Methyl Sulphate. JAMES BURMANN (Bull. Xoc. chirn. 1906 [iii] 35 801-803).-Commercial methyl sulphate is added in small portions at a time to excess of a 10 per cent. aqueous solution of ammonia cooled to - 5'. The product is then added to excess of a 30 per cent. aqueous solution of sodium hydroxide and the mixture distilled the issuing gas being passed into hydrochloric acid (20 per cent.). On evaporating the ammonium chloride separates first and the methyl- amine hydrochloride ultimately obtained is purified by recrystallisation from boiling absolute alcohol The yield is about 35 per cent. of the theoretical. T. A. H. Liquid Methylamine as a Solvent and a Study of its Chemical Reactivity. HARRY D. GIBBS (J.Amer. Chern. Xoc. 1906 28 1395-1422).-Liquid methylamine is a very good solvent for934 ABSTRACTS OF CHEMICAL PAPERS. organic compounds being better than liquid ammonia and probably better than methyl alcohol. For inorganic compounds however it is not so good a solvent as liquid ammonia is far infdrior to water and seems to be approximately equal to methyl alcohol. The solubilities of various organic and inorganic substances have been studied as well as the reactions which sometimes take place. The hydrocarbons are generally very soluble and the solid members crystallise readily from the solutions The alcohols and phenols are also readily soluble. The following additive compounds are described. The phenol compound C6H,*OH,2NH,Me melts a t S*5-9*0". The a-naphthol compound C,,H7*OH,2NH,l\le melts a t about 37".Quinol yields the compounds C,H4(OH),,8NH2Me C6H,(OH),,2NH,Me and C,H,(OH),,NH,Me the last melting a t 105'. Resorcinol gives the compounds C,H,( OH),,5NH2Me C6H,(0H),,2NH,Me and C,H,(OH),,NH,Me the last of which melts a t 95". Pyrogallol furnishes the compounds C6H,(OH),,3NH,Me and C6HI,(OH),2NH2&1e. With phenolphthalein the compound C6H4:C202:(C,;H4*0 H),,3NH2Me is obtained and with alizarin the compound C,~,~C,O2~C,H,(~H),,2NH,Me is produced. On evaporating a solution of picric acid in liquid methyl- amine a substunce is obtained which decomposes without melting a t 195'. Acetaldehyde and benznldehyde are miscible with liquid methyl- amine. m-Nitrobenzaldehyde is readily soluble and gives the compounds N0,*C6H4*CH0,6NH,Me melting a t - 9" and N0,*C6H4* CHO,NH,&le which melts and decomposes a t 47".Acetone acetophenone and carbamide dissolve readily in liquid methylamine. Benzil is also very soluble and yields a substance COPh*COPh,2NH2Me which melts at about 23". Quinone reacts with methylamine with development of heat and formation of a liquid which becomes successively green purple and black. Ant hraqninone is only slightly soluble. The organic acids are generally very soluble but in some cases insoluble methylamine salts are produced. The methylamine salts of several organic acids are described. The acetate melts at about SO" the p a h i t a t e at 62" the szcccinate at 150" the turtrute a t 148" the benxoute at 110-112° and the o-niti*obenzoute at 128-129'.Phthslic anhydride reacts with methylamine with development of heat and formation of a crystalline substame which is probably metluJanzine methyZphthaZamute NHMe- CO*C,H,*CO,H,NH,Me.

Galactose and dextrose are soluble in liquid methylamine and furnish compounds of the composition C,Hl,0,,2NH,Me. Sucrose is also readily soluble. Acetamide phenylhydrazine amyl formate pyridine azobenzene m-nitrobenzenesulphonnmide and benzenesulphonimide are very soluble in liquid methylamine. Diphenyl ketoxirne dissolves readily and yields the compound CPh, N OH,NH,Ne which decomposes a iittle below 1 4oo. Gallein and ccerulein furnish the conzpounds C2,H1207 3NH,Me and C2,H,,0,,2NH2Me. Dichlorogallein and tetrachlorogallein yield products containing about 23 and 25 per cent.of methylamine respectively. Indigotin and rosaniline are readily soluble whilst methyl orange is only slightly so. The behaviour of a large number of inorganic salts with liquid methy lamine is described. The sulphates are usually insoluble whilst of the nitrates and haloids some are soluble and others insoluble. The following additive compou??,ds are described CdI 4NH,Me AgN0,,4NH2Me and AgN0,,2NH2Me. Bismuth chloride calcium chloride chromic chloride lithium chloride lithium nitrate lead nitrate mercury methyl chloride mercuric iodide and probably cuprous chloride cupric sulphate mercurous chloride and mercuric cyanide also form products containing methylamine of crystallisation. E. G. Compounds formed by the Action of Ammonia or Amines on Mercury Salts.DANIEL STR~MHOLM (Arkiv Ken2. Min. GeoZ. 1906 2 No. 23 1-25).-The author classifies the definite compounds formed by ammonia or amines with mercury salts as follows ( A ) Those in which Hg X = 1 2 ; these are regarded as ammonia compounds. ( B ) Those in which Hg X is greater than I 2 and which are of the types (1) with ammonia NH,*HgX Hg:N-HgX and Hg:N*HgX + H,O ; (2) with primary amines NHEtOHgX and Hg(NR*HgX),. Compounds of the last type have not previously been prepared although references have been made in the literature to ammonia derivatives of this type; the existence of the latter however the author was unable to confirm. Working under the same conditions as Kohler (Abstr. 1880 159 and Ber. 1879 12 232l) the author was unable to obtain any of the three compounds of et hylamine and mercuric chloride described by t h i s author.Instead he obtained the compound N,Et,Hg,Cl as a white amorphous mass. Other compounds prepared from amines are NHEt,,HgCl from diethylamine ; N,Pr,Hg,Cl from propylamine ; N,Me,Hg,Cl from methylamine. Cornpounds were also obtained from amylamine (Hg C1= 1.15 1) and benzylamine (Hg C1= 0.97 1).

ALESSANDRO CALLEGARI (Guzxetta 1906 36 ii 63-67. Compare Bruni and Fornara Abstr. 1904 i 855; 1905 i 263; Ley Abstr. 1905 i 1'75).-The copper salt of P-aminopropionic acid (p-alanine) prepared by warming the acid with freshly precipitated copper hydroxide has the properties of an ordinary copper salt and not those of a cupram- monium derivative (loc. cit.) ; the cuprammonium or nickelammonium salts appear to be formed only from a-amino-acids. Copper uminosul- phonate (~NH2*S0,*O),Cu,2H,0 prepared by dissolving copper car- bonate in an aqueous solution of aminosulphonic acid forms micro- scopic blue crystals and is an ordinary copper salt; the nickel salt (WH,~SOq),Ni,4H,0 is similar. The copper salt of hydrazinecarb- oxglic acid (Stoll6 and Hofmann Abstr.1905 i 28) is apparently a cuprammonium salt as it has the intense violet colour characteristic of such salts; it cannot be isolated as it rapidly decomposes giving metallic copper. The nickel salt (NH,*NH*CO,),Ni can be isolated and is a nickelammonium salt ; its solution is intensely blue and does not respond to the usual tests for nickel. G. T. M. W. A. D. Optically Active ap-Diaminopropionic a- and P-Thioglyceric Acids. CARL NEUBERG and ERJCH ASCHER (Chem. Centr. 1906 ii 11 19 ; from Biochem. Zeit. 1906 1 380-382).-The racemic variety of up-diaminopropionic acid can be split into its optically active con- stituents by the fractional crystallisation of its salt with d-camphor- sulphonic acid; in this way the dextro-variety can be obtained practically pure.The sulphate of the latter is converted by barium nitrite into I-glyceric acid from which it follows that dextrorotatory up-diaminopropionic acid is in reality a laevo form. The hydrochloride of I-diaminopropionic acid is dextrorotatory ; it forms a copper salt (C,H,02N,),C'u,H2~0. When proteincystin is treated in sulphuric acid solution with barium nitrite it is converted into up-thioglyceric acid which has [a] - 10.6" (approx.) ; its barium salt (C3H,0,S),Ba has [u]. - 19*08". A solution of the barium salt gives heavy precipitates with mercuric chloride lead or copper acetates. Zinc and hydrochloric acid reduce the disulphide to P-thioglyceric acid a substance which with lead copper,or iron salts gives colour reactions similar to those of cystein.In preparing the inactive up-diaminopropionic acid from ap-dibromo- propionic acid arid ammonia 10 per cent. of the dibromo-acid is VOL.

LOUIS BOUVEAULT and RENE LOCQUIN (Bull. h'oc. chim. 1906 f iii 1 35 965-969).-PtIost of the facts recorded in this paper have already been given (Abstr. 1905 i 636).-'CVhen ethyl a-oximino-p methylvalerate is reduced with sodium amalgam in st cold alcoholic solution only 35 per cent. of the theoretical yield of ethyl a-amino-P-methylvalerate is obtained but a 60 per cent.yield may be secured by effecting the reduction with zinc dust and alcohol saturated with hydrogen chloride. From this amino-ester the corresponding acid (Ehrlich's isoleucine Abstr. 1904 i 560) may be obtained by agitating its solution in ether with a dilute aqueous solution of sodium hydroxide. The acid yields a p-toluenesulphonate which melts at 139O and when warmed with formic acid (compare Fischer and Warburg Abstr. 1906 i 72) furnishes the formyl derivative CHMeEt*CH(NH*CHO)*C02H which crystal- lises from boiling water and melts at 121-1229 The amino-acid pre- pared in this way is racemic. With benzoyl chloride in cooled pyridirie solution ethyl a-xminoiso- hexoate forms a benxoyl derivative which crystallises from a mixture of alcohol and light petroleum melts a t 79" and boils a t 211' under 15 mm.pressure.

When isobutyl chloride is condensed with ciimene in presence of aliuninium chloride tert.-butylbenzene p-di-tert.-butylbenzene and propyl chloride are produced. An attempt to separate the constituents of this mixture by Radziewanowski's process (Abstr. 1895 i 129) gave only a tarry product which boiled above 300' and decomposed. When isoamyl chloride is condensed with tert.-butylbenzene in presence of aluminium chloride p-di-tert.-butylbenzene is produced and the isoamyl chloride can be recovered unaltered (compare Baur Abstr. 1894 i 445).

Y. Influence of the Position of the Ethylene Linking on the Electro-affinity and Characters of Unsaturated Allicyclic Acids. G ~ N O ABATI (Rend. Accad. Sci. Fis. M a t . Nupoli 1906 [iii] 12 220-226),-From a study of the affinity constants of the naphthoic and the hydronaphthoic acids benzoic acid phthalic and the hydrophtbalic acids it is seen that apart from the strongly negative character of the aromatic nucleus the presence and position of the double linking have no small influence on the energy of an acid. I n the aa- and py-positions the double linking produces a great increase in the value of the electrical conductivity whilst when i t is in the up- or y8-position the values of the conductivity are not much greater than those of the corresponding saturated acids.The explanation given by Fichter and Pfister (Abstr. 1904 i 965) of their results on the basis of Thiele's theory of partial valencies is fallacious. According to Thiele's theory the y8- &c. acids should be as unsaturated as the py-acids whilst the fact is that they are far weaker than these and have constants not differing greatly from those of the @acids. This contradiction of Thiele's theory is confirmed by the constants for acids having a double linking in the aa-position withORGANIC CHEMISTRY. 959 respect to the two carboxyl groups. For instance in the case of the four tetrahydrophthalic acids the A]-acid should according to Thiele's theory be the most saturated and should hence be the least energetic. Instead however the constant of this acid is the greatest of the four and is five times that of the A4-acid which has six partial valencies.Similar disagreement with this theory is offered by the constants for citraconic mesaconic and i taconic acids. When treated with alkali hydroxides unsaturated py-acids do not pass completely into the ap-isomerides the reaction being reversible. Further in the reduction of phthalic acid by means of sodium amalgam there is a marked tendency to the formation of acids with a double linking in the py-position alth'ough the temperature is kept at about 150' for some three hours and the proportion OF sodium hydroxide present in the liquid ultimately reaches 15 or 30 per cent. It is therefore unsafe to assign the &-constitution to acids on the sole ground that they undergo transformation with alkali hydroxides as has been done by Perkin and Pickles in the case of the tetrahydroiso- phthalic acids ('l'rans.1905 87 293).

Titration of aqueous solutions of the anhydrides with barium hydr- oxide solution using methyl-orange as indicator shows that although they cannot be obtained in the solid state in the form of acids they behave as acids when dissolved in water; this fact is also shown by the high value of the affinity constants which are in accord with the constitutions given previously (Zoc.cit.) as it has been repeatedly observed that a double bond in the py-position effects a marked increase in the energy of unsaturated acids.

HANS STOIIBE (Anncden 1906 349 333-37 l).-The author cites numerous examples to show that the colour of the fulgenic acids and of similarly constituted substances is to be explained not only by the number and the position of the chroinophoric phenpl ant3 carhoxyl groups i n the carbon chain but also by the influence of the con- jugated double linkings. The fact that a 8-diphenyl-AaY-biitadiene-6- carboxylic acid and a 8-diplienylfulgenic acid are colourlcss whereas a 8-diphenyl-Av-butadiene-y-carboxylic acid is yellow is ncconnted for on stereochemical grounds.

Sodium hyposulphite may be used in the reduction of compoimds other than those containing an azo-group. Nitrobenzene gives poor yields of aniline ; o-nitrophenol is reduced to o-aminophenol ; in these cases sodium sulphide is a better reducing agent than the hyposulphite. The quinones benzoquinone P-nnphthaquinone and phenanthra- quinone are readily reduced by sodium hyposulphite to the corres- ponding quinols ; oxanthranol is obtained more readily by reduction of anthraquinone in this manner than by Graebe and Liebermann's method (this Journal 1872 25 139).Benzil is reduced by sodium hyposulphite to benzoin.

On addition of water or alcohol to the acid solution the P-diazo- hydroxide C,,H,O,( OH);N,*OH is thrown down as a scarlet or orange-red precipitate ; this darkens on exposure to air decomposes at 1 3 5 O and detonates when heated. It is decomposed by boiling dilute acids aqueous a1 kali hydroxides or alcohol forming alizarin only after prolonged drying or contact with dilute sulphuric acid.With potassium iodide the diazo-derivatives of alizarin form iodo- alizarins which dye mordanted stuffs brown. Azo-dyes cmnot be obtained by coupling a-diazo-alizarin sulphate in alkaline or acid solution whilst only a small amount of an unstable dye is formed by coupling 9-diazoalizarin hydroxide with R-salt in alkaline solution. Experiments are quoted to show that the stability of the diazo- derivatives of benzene and naphthalene increases with the size of the nucleus ; it was to be expected as is found that the diazo-derivatives of anthracene would be still more stable. P-Diazoalizarin hydroxide resembles to some extent the diazonaphthalenes ; in the a-derivatives the characteristics of the diazo-compounds are still less prominent.When heated with sulphuric acid containing 20-40 per cent. of the anhydride and poured into water a-aminoalizarin yields a reddish- brown precipitate which when boiled with water is converted into a-uminoulixc~rin-3-sul~honic ucid (4-cmuino-I 2-dihydroxyc~nt7~ruquinone- 3-sulphonic acid) C,,H,0,(OH)2(NH,).S03H (J3.R.-P. 82938) ; this crystallises from alcohol in microscopic nodular aggregates is almost insoluble in ether and forms a dark violet insoluble barium salt and a silver salt crystallising in microscopic reddish-brown needles. Oxida- tion of the sulphonic acid leads to the formation of phthalic acid. When diazotised and heated in concentrated acid solution at 50-60° a-aminoalizarin- 3-sulphonic acid yields purpurin-3-sulplo~~c acid which is isolated in the form of its sparingly soluble potassium salt Cl,H70,SK and is probably identical with the acid obtained by sulphonation of purpurin or by oxidation of alizarinsulphonic acid with nitric acid (D,R.-I?.84774) together with alizarin-3-snlphonic acid which is considered to be identical with the acid formed by the action of fuming sulphuric acid on alizarin. Purpurin-3-sulyhonic and alizarin-3-sulphonic acids are formed also by boiling diazotised 4-aminoalizarin-3-sulphonic acid with aqueous sodium hydroxide. G. Y.

Dihydropinenecarbithionic acid obtained by adding carbon disulphide t o the ethereal solution of the magnesium compound of pinene hydro- chloride is a brown oil having a camphoraceous odour ; it is extremely decomposable but yields characteristic metallic salts.The interaction of sulphur and the magnesium compound of pinene hydrochloride leads to the production of thioborneol together with snialler quantities of dihydrodicamphene bornyl disulphide and other substances containing a larger proportion of sulphur. On oxidation with dilute chromic acid a t moderate temperatures thioborneol is converted almost quantitatively into bornyl disulphide ; at higher temperatures the latter decomposes into thioborneol and thiocamphor so that by working under these conditions all the sulphur compounds obtained from the magnesium compound of pinene hydro- chloride can be converted into thiocamphor. On exposure to the air or more rapidly by the action of oxygen thiocamphor evolves sulphur dioxide and becomes converted into a colourless odourless substance melting a t 168" which is probably bornyl sulphide.

When one commercial sample freed from these constituents was mixed with light petroleum a resin separated in amount equal t o about 30 per cent. of the oil ; this con- tained oxygen and when reduced in amyl-alcoholic solution with sodium yielded a sesqui terpene appai ently identical with cadinene. By fractional distillation of the. oils over metallic sodium pinene dipentene and limonene were isolated ; it is an open question whether the dipentene is present in the original oils.From one commercial sample a fourth terpene ClOHl6 also was isolated possibly a n intermediate stage between limonene and dipentene; it boils at 78-80' under 20 mm. pressure has a sp. gr. 0.847 at 20' and [ a]D + 80" at 20' ; it forms a tetrubromide melting a t 11 5' a monohydrochloride melting at 6" and an oily nitrosochloride.

The benxoyl derivative of santal oil prepared either by heating the oil with benzoic anhydride at 110' or by condensing i t with beiizoic chloride in the presence of pyridine has a sp. gr. 1.047 at 1 5 O and boils at 236-238" under 15 mm. pressure. This preparation is not volatile in steam and may thus be separated from the unbenzoylated santal oil. The salicyl derivative is made by heating snntal oil or pure santalol with salol and a small proportion of sodium hydroxide under diminished pressure until the elimination of phenol is complete ; the 8p.gr. is 1.07 and the salicylsantalol boils with partial decomposition at 250-260" under 20 mm. pressure.

Compare this vol. i 997).-Tbis paper contain9 the results of experiments devised to elucidate a curious case of isomer- ism among the azophenols. The p-azophenol obtained by reducing p-benzoquinoneazine differs from the substance prepared by the ordinary methods in its colour in the crystalline and powdered con- dition in its behaviour towards moist air and in its solubility in cold benzene.The new modification is denoted by the affix (a) and the older form by (@). It seems probable that these a- and @-compounds are geometrical isomerides. p-Azophenol (a) most conveniently pre- pared by fusing y-nitrophenol with pot&ssium hydroxide crystallises in a mono-hydrated form from ether or alcohol formiug pale brown or amber-yellow plates with blue reflex. The solubility of the hydrated form in benzene a t 17' is 1 in 10,800 ; the anhydrous form separates from this solvent in cruciform aggregates of greenish-brown crystals. The powdered a-compound assumes a dark yellow colour which *be- comes green on heating. Both hydrated and anhydrous forms melt and decompose a t 215".A glacial acetic acid solution of hydrogen bromide furnishes blue crystals of the hydrobromide C,,H,,N,,HBr. p-Azophenol (p) prepared by reducing y-benzoquinoneazioe with phenylhydrazine in benzene solution forms dark red and reddish-brown leaflets with a blue reflex; when powdered it is brownish-red with a blue tinge and a t 110-140" it assumes a brick-red colour. The solubility of the p-compound in benzene a t 17' is 1 in 1500. On heat- ing a portion of the @-compound under reduced pressure a small yield of the green pulverulent anhydrous a-modification is obtained. The a-compound is partially converted into the @-modification by heating with moist ether. The two isomerides behave similarly towards dry ammonia gas yielding anhydrous diammonium salts which completely dissociate in the air or in the desiccator ; they are oxidised with equal readiness by silver oxide and are equally stable towards phenylhydr- azine with which they each combine to form a crystallisable salt C12H1 oOP2 ,C,H*N,* o-Azophenol when prepared by the potash fusion method from o-nitrophenol is accompanied by a by-product triphenodioxazins The o-azo-compound takes up 1 mol.of ammonia to form a coffee- brown ammonium salt ; if however it has been previously melted or distilled in a vacuum i t does not show any tendency to combine with dry ammonia but regains the power on recrystallisation or exposure to an etmosphere of damp ammoilia. m-Azophenol which combines with a proportion varying between 1 and 2 mols. of ammonia does not react in ethereal solution with silver oxide.ClFY 1 *O,N,* G T.

Compare Abstr. 1905 i 492 this vol. i 774).-After reviewing the present state of knowledge of the hydroxyazo-compounds the properties of the f ol lowing azo-com pound s derived from eugenol are discussed a t some length. The principal con- clusions arrived at are as follows. All the azoeugenols are nearly insoluble i n col(1 0.5 per cent. aqneous sodium hydroxide but dissolve much more readily in the sttine liquid at 100". No change in the boiling point of the sodium hydroxide solution occurs on adding successive quantities of the azo-compound ; this behaviour which is also shown by phenol and a-naphthol is held t o prove tbat the azoeugenols yield ttue sodium salts which are dissociated to almost the same extent as sodium hydroxide.On cooling the solutions the sodium salts undergo hydrolysis to the extent of about 58-92 per cent depending on their structure the original azoeugeuol separating in crystals. No simple connexion can be traced between the degree of hydrolysis of the salts and their solubility. The hydrolysis is held to show that the azoeugenols are pseudo-acids giving salts only in virtue of a molecular change; they do not redden litmiis or com- bine with ammonia in dry beuzene. From their chemic;tl brhaviour the free azoeugenols appenr to be neither hydrazones nor carhonyl conipounds.When boiled with acids or alkalis they do not undergo hydrolysis t o form a corresponding quinone ; and all hough they interact vigorously with phenylhydrazine at 110' the product is never a dihydrazone but always aminoeugenol formed by reduction. Such a reducing action is not observed when ordinary aromatic phenyl- hydrazones are heated with phenylhydrazine. With hydroxylmiine the azoeugenols fail to interact. 'l'he behaviour of the azoeugenols when treated mil h sodium ethoxide and subsequently with ethyl iodide in alcoholic solution depends on the nature of the aromatic radicle attached to the azo-group. o-Toliiene- azoeugenol as-~m-xyleneazoeugeno1 a1 1 d p-xyleneii zoeu genol do not f orrn ethers ; these sub-tances coutain a methyl radicle i n the ortho-position relatively t o the azo-group.Benzeneazoeugenol rr~-tolueneitzoeugenol and p-bromobenzeneazoeugenol give unstable ethers which are a t once hydrolysed at the ordinary temperature by 0.5 per cent. aqueous sodium hydroxide. Azoeugenols containing negahive elements or radivles in any position (with the exception of p-broruobenzeneazoeupenol) give well-defined ethers which are hydrolysed only by warm sodium hydroxide. l'he ethers differ entirely from the pirent azoeugenols in their behaviour with phenylhydrazine ; nb action occurs at 110' and very little at 170-180°. I n no case is aminoeugenol ethyl ether formed. The ethyl ethers of the azoeugenols appear to hare the structure R*N:N*C<cP-u(C C( OEt)*C(OMe) ]>CH of true oxygen ethers.The acetyl derivatives of the azoeugenols are i n all cases easily prepared and are decoinposed only slowly by boiling aqueous sodium hydroxide. Like the parent azoeugenols they interact readily with phenylhydrazine at 1 10-1 20° undergoing reduction to aniinoeugenol ; acetylarninoengenol is never formed. The wetyl derivatives thus differ 3 5992 ABSTRACTS OF CHEMICAL PAPERS entirely from the ethyl ethers and cannot have an analogous structure ; the behaviour with phenylhydrazine is moreover held to exclude the structure NE1Ac.N C<CH c(c '(OMe)>CH.

Benzaldehyde and salicylaldehyde (X = H,OH) form both a hydrazone melting in the former case at 159-160° and a tri- molecular condensation product melting in the latter case at 130'; m- and p-nitrobenzaldehydes (X = NO,) form only hydraxones which melt at 177" and 160-161' respectively ; and cinnatmaldehyde forms only a termolecular condensation pi-odzcct melting a t 124'. m-Bromobenzaldehyde yields a b a d e melting at 137' of which the constitution has not yet been elucid;tted.

The first acid coudenses when suspended in glacial acetic acid and treated with aromatic aldehydes C,H,X*CHO to yellow or red Aydmxones C,H,*N:N*C,H;NH*N :CH*C',H,X ; these have the char- acter of mono-acid bases and unite with the sulphuric acid (pro- duced by the elimination of the sulphonic group) to form a blue or green sulphate which is decomposed 'more or less by hot water com- pletely by ammonia.No products were obtained t h a t proceeded from the condensation of two molecules of the hydrazinesulphonic acid with one of the aldehyde.

RICHARD WILLST~TTEB and LUDWIG KALB (Bey. 1906 39 3474-348%).-This investigation was undertaken with the object of ascertaining the nat.ure of a yellow crystalline oxidation product of benzidine obtained by oxidiaing the diamine with silver oxide or lead peroxide in inert solvents. This object has been attained by preparing the substance synthetically from 4-nit8ro-4'-aminodiphenyl the acetyl derivative of which crystallises in prisms and melts a t 240O.4 4-Diamino-4' 4'-azodiphenyl N,(C,H,*C,H,*NH,) obtained by reducing 4-nitro-4'-aminodiphenyl with zinc dust and alcoholic sodium hydroxide corresponds in every respect with the product of the oxida- tion of benzidine (Abstr. 1905 i 361) ; i t crystallises in microscopic yellowish-red needles melts at 2 8 7 O and develops a characteristic blood-red coloration with concentrated sulphuric acid. The salts of this base with the mineral acids are insoluble in water; the mono- hydrochloride C,,H2,,N4,HCl consists of small brown prisms ; the dihydyoclJoride C2?H2?N4.2 HCJ is amorphous. s-Diacetyl-4 4-daatrizno-4' 4'-axodiphenyl produced from the diamine by the action of acetic anhydride melts indefinitely and deconipoaes a t 3 7 3 O .Tetra-axo-axodiphe?zyl chloride N2(C,~H,*C,H4*N,C1),,2H20 is pro- duced most readily by diazotising the corresponding diamine with a large excess of hydrochloric acid (1 per cent.) and aqueous sodium nitrite (10 per cent.) when the salt is precipitated from the clear solution thus obtained by the addition of concentrated hydrochloric acid. The chloride which consists of prismatic crystals having a violet reflex gives a n orange-red streak; it is moderately stable in air and decomposes violently a t about 95". The tetra-azo sulphate and nitrate are both crystalline the latter being exceptionally insoluble ; the platinicldo~zde C,,HIGN,PtCI tl,O is an insoluble yellow floccu- lent precipitate.G. T.

Compare Nietzki and Guitermann Abstr. 1887 732; Reverdin and De la Harpe Abstr. 1893 i 478).-The action of diazobenzene chloride on 1-hydroxy-2-naphthoic acid in alkaline solution leads to the formation of dibenzeneazo-a-naphthol (Noelting and Grandmougin Abstr. 189 1 1076j which is formed also by th9 action of diazobenzene chloride on benzeneazo-1 -hydroxy-2-naphthoic acid. The reduction of benzeneazo-1-hydroxy-2-naphthoic acid by means of sodium hyposulphite in aqueous alcoholic solution (compare this vol. i 716) leads to the formation of aniline and 4-amino-1-hydroxy-2-naph- thoic acid (Nietzki and Guitermann loc.cit.) which crystallises in slender colourless needles forms a crystalline hydrocldoride and yields 4-amino-a-naphthol when heated in a current of hydrogen chloride or naphthaquinone when treated with nitrous acid.

By KICHARD WILLST~TTER and MAX BENZ (Ber. 1906 39 3482-3491).-4 4’-Dihydroxydiphenyl and 4 4’-dihydroxy- stilbene resemble catechol in being oxidised to quinonoid substances by silver oxide or lead peroxide but 4 4’-dihydroxydiphenylmethane does not exhibit this behaviour. Hence it appears that the ethylene linking *CH:CH* does not sever completely the quinonoid relationship between the two benzene nuclei whereas this connexion is quite annulled by the interposition of the methylene group.It is now shown that the azo-group is analogous to the ethylene group the p-azophenols under- going tbe characteristic oxidation. p-Beiaxoquinoneaxine O:C,H,:N*N :C,H,:O prepared by shaking an ethereal solution of p-azophenol with silver oxide and fused sodium sulphate crystallisee from organic solvents either in dark orange-red prisms or needles or in dark yellow rhombohedra1 leaflets or plates ; both modifications have a blue reflex. When treated in dry ethereal solution with concentrated sulphuric acid the quinoneazine yieldsp-azo- phenol and an easily decomposable base ; sulphurous acid or preferably phenylhpdrazine reduces the quinoneazine to an azophenol which is not identical with ordinary p-azophenol.The quinhydrone C H 1804N4 of y-benzoquinoneazine separates in bluish-black needles with a bronze reflex on mixing ethereal solutions of p-azophenol and the quinoneazine ; it melts at l8l-18Zo and under- goes dissociation in alcoholic solution. 4 4’-Dihydroxystilbene when oxidised with lead peroxide or potass- ium ferricysnide gives rise to stilbenequinone which is again reduced by phenylhydrazine t o the original dihydroxy-compound. p-AcetyZami~iodic~xoamino 3enzeibe C,H,*NH N,* C,H *NH Ac the in- termediate product of the interaction of diazoacetanilide and aniline crgstallises in orange-yellow aciciilar prisms and melts and decomposes at 150-152’. p-Amminodiaxoaminobenxene C,H,~NH*Nz*C,H,’NHzl obtained by hjdrolysing the foregoing compound with sodium ethoxide crystallises998 ABSTRACTS OF CHEMICAL PAPERS.from dilute alcohol in brownish-yellow needles decomposing a t 157". Azoaniline which is produced together with a preponderating amount of aminoazobenzene by warming the foregoing diazoamine with aniline and aniline hydrochloride does not undergo the quinonoid oxidation on treatment with silver oxide or lead peroxide. R. W. ROSENKRANTZ (J. Buss. Php. Chem. Soc. 1906 38 i 2-3).-Crystals of egg-albumin obtained by a modification of the Hofmeister-Krieger process are crystallised 6 to 10 times. They are then dissolved dialysed evaporated in a vacuum and again dialysed. Preparations so obtained give no ash on ignition and do not contain recognisable quantities of ammonium sulphate. 2.K. G. T. M. Ash-free Egg Albumin. Complexes of Pure Albumin. ANDRE MAYER (Compt. rend. 1906 143 515-516).-Pure ovalbumin obtained from white of egg by diluting with water filtering the precipitated globulins recovering the albumin by prolonged dialysis and repeating the processes several times has a specific electrolytic conductivity of 1-10 -5 is not coagulated by heat but forms soluble complexes with acids (HCI HNO H,SO,) bases (NaOH KOH) or salts [NaCl KCl MgC12 CiLCl (NH4&,S04 MgSO Na2S04 K,SO,]. The amount of electrolyte absorbed by a definite quantity of ovalbumin to raise the electrolytic conductivity from 1.10-5 to 1.10-4 varies with the nature of the electrolyte being greater in the case of the acids than the bases o r univalent salts and greater in the case of the univalent than the bivalent salts.Ovalbumin forms insoluble complexes with salts of the heavy metals or positive colloids which are soluble in dilute solutions of electro- lytes and for this purpose N/l60 HCl; N/140 NaOH; or ~V/30 NaCl are equivalent ; from the solution a precipitate is foimed lty dilution or by dialysis and the solution is coagulated by heating the temperature a t which coagulation occurs varying with the nature of the electrolyte used as the solvent. Thus a solution of an albumin- zinc salt coagulated at 56O 60° or 86" according as it had been dib- solved in hydrochloric acid sodium chloride or potassium hydroxide respectively. I n respect of all these properties the insoluble albumin complexes closely resemble tbe globulins which may be regarded as complexes of pure albumin.M. A. W. Distinction between Serum-albumin and Myo-albumin. 1030-1031. Compare Abstr. 190-1 i 837 ; 1905 i 72S).-Aqueous extracts of the muscle of the cow calf horse or turkey and of whiting evolve hydrogeri sulphide on addition of sulphur and this property is also exhibited by the coagulated albumins obtained by heating these extracts. The insoluble white residue left after repeatedly washing horse-muscle with water is almost inactive towards sulphur and appears to behave as an inactive reserve for the more active and soluble myo-albumin. The latter is rendered inactive by contact with sulphur for several days and the coagulum obtained from this is similarly inactive towards sulphur.

T. A. H. Philothionic Hydrogen. JOSEPH DE REY-PAILHADE (BUZZ. Xoc. chim. 1906 [iii] 35 1031-1033. Compare preceding abstract and Heffter and Hausmann Abstr. 1904 i 461).-The philothionic hydrogen of myo-albumin is not destroyed after 15 days' exposure to air at the atmospheric temperature whereas it is much more rapidly removed by sulphur (see preceding abstract). In this connexion it is pointed. out that hydrogen and sulphur combine a t 250° whereas hydrogen and oxygen do not unite below 350° and it is suggested that whilst philothion seems to be capable of effecting the same chemical change as is induced by an increase in temperature of about 250° its activity is insufficient to cause a combination which requires an increase of 350'.T. A. H. Monoamino-acids of the Crystalline Proteid from Pumpkin Seeds. EMIL ABDERHALDEN and OSCAR BERGHAUSEN (Zeit. physioZ. Chem. 1906,49,15-2O).-The substances obtained from the cleavage of edestin (vitellin) by means of dilute sulphiiric acid were glycine 0.08 ; alanine present ; aminovaleric acid 0.7 ; leucine 4.7 ; proline 1.7 ; glutamic acid 13.4 ; aspartic acid 4.5 ; phenylalariine 2.6 ; and tyroslue 1.4 per cent. .

Compare this vol. i 545).-The specific rotatory powers of solutions of gliadin in methyl ethyl propyl and benzyl alcohols phenol p-cresol and glacial acetic acid have been determined and the results are tabulated. The gliadin was prepared from wheat-flour and the experiments were made i n connexion with an investigation which is in progress with a view to the improvement of the methods of flour analj sis. E. G. Iodospongin. Preliminary Note. L. Scoiv (Chem. Cenls'. 1906 ii 1133 ; from Biochent. Zcit. 1906 1 367).--The non-digestible residue of sponge substance can be rendered soluble by treatmeit with concentrated sulphuric acid. The product is then digested with pancreatic juice until it no longer gives the biuret reaction. After separating the diamino-acids an organic compound rich in iodine is obtained which is purified from monoamino-acids by the fractional crystallisation of its copper salt. The Rendering Insoluble of Gelatin by Formaldehyde. AUGUSTE LUNI~RE LOUIS LUMI~RE and ALPHONSE SEYEWETZ (Bull. SOC. cliim. 1906 [iii] 35 873-4379 Compare this vol. i 614 915).- When gelatin is soaked in a solution of formaldehyde the insoluble product formed contains from 4 to 4.8 per cent. of the aldehyde. The rapidity with which the formaldehyde is absorbed under theee conditions increa>es with the concentration of the solution but is not P. H.1000 ABSTRACTS OF CHEMICAL PAPERS. sensibly influenced by increase of temperature. Gaseous formaldehyde is absorbed more slowly by gelatin but the product ultimately formed is similar to that obtained in the first case. The precipitate produced by mixing solutions of gelatin and formaldehyde contains unaltered gelatin. Gelatin rendered insoluble by formaldehyde is slowly decomposed by hot water and the formaldehyde may be completely eliminated by this means. The same decomposition is brought about by macerating the product in cold dilute hydrochloric acid and this method was used for the liberation and ultimate estimation of the formaldehyde by Seyewetz and Gibello’s process (Abstr. 1904 ii 521). The form- aldehyde is also gradually liberated from the insoluble product when the latter is heated a t 110’. From these results it is concluded that when gelatin is treated with formaldehyde an additive product rather than a true compound is formed. Intramolecular Absorption of Water in the Tryptic Digestion of Proteid. PAUL H ~ R I (P’iiger’s A?*chiv 1906 115 52-63).- Elementary analysis shows that the products (peptone) of the action of trypsin on proteids contain more oxygen and more hydrogen than the original material. This is attributed to the intramolecular absorp- tion of water T. A. 1%. W. D. H. Tryptophan. CARL NEUBERG (C‘hent. Centr. 1906 ii S92 ; from ChccritS Awn. 30).-The author suggests the following modification of Hopkins and Cole’s method of preparing tryptophan. I n the second precipitation with mercuric sulphate the first portions consisting almost entirely of cystine and mercury-cysteine should be rejected ; the filtrate is then treated with hydrogen sulphide and after boiling oE the excess of the latter an excess of lead carbonate is added (100 grams of lead carbonate per kilogram of casein). The whole is then warmed on a water-bath for half an hour ammonia is added until the solution smells faintly and the heating is continued for a quarter of an hour more. The dissolved lead is then precipitated by means of hydrogen sulphide and the solution is evaporated ; perfectly pure white tryptophan separates out in a yield of 7-8 grams per kilogram of well-digested casein. P. H. Myelin Bodies. J. G. ADAMI and L. ASCHOFF (Proc. Roy. Soc. 1906 78 B 359-368).-The term myelin was originally applied by Virchow to a constituent of the white substance cf nerves which swells up with water and develops curious forms with a double contour. Myelin bodies have since then been described in many situations in cell protoplasm under both physiological and pathological conditions. Many soaps exhibit the same phenomena. The globules formed are doubly refracting and the hypothesis is advanced that they are fluid sphaerocrystals. With regard to their chemical composition there is still much doubt but the evidence appears to point to two principal varieties namely cholesterol oleate and choline oleate. W. D. H.
