Compare Abstr. 1904 ii 45).-Three further samples of Louisiana petroleum have been exitmined but of these only one which was obtained from Bayou Bouillon near St. Martinsville was i n sufficient quantity for extended invostigation. The results of the examination of this specimen showed that the oil was composed mainly of hydro- carbons of the seriss CnH2n,2 and CnH2n-4 and no evidence was obtained of the presence of unsaturated compounds or of optical activity. E. G. Thorianite a New Mineral from Ceylon. JVYmHA&i R. DUNSTAN and GEORGE S. BLAKE (Proc. Boy. Xoc. 1905 A 70 253-265. Compare Dunstan Abstr.1904 ii 744).-The crystal- lographic character of thorianite is described and the results of analysis of another specimen of the mineral are communicated.

Thorianite possesses the advantage not shared by any known thorium mineral of containing uncombined thoria soluble in nitric acid with formation of thorium nitrate. The powdered mineral dissolves readily also in diluted sulphuric acid with evolution of a gas which is chiefly helium. Thorianite is scarcely attacked by hydro- chloric acid. The hardness of thorianite is nearly 7 and the density of different specimens varies from 8-9-7.So far as the investigation has gone it appears probable that thorianite is isornorphous with uraninite and that in the thorianite of Ceylon some of the thoria is replaced by the corresponding uranium oxide. The evidence however is not sufficient to show whether this is a case of isomorphous mixture as seems probable or of true chemical replacement. Thorianite is highly radioactive and measurements of the rate of decay of the emanation indicate the presence of radium in the mineral (compare also Hahn this vol. ii 432 789). J. C. P. Cry&allised Slag from Hettstedt Composition of Melilite. FERRUCCIO ZAMBONINI (Zeit. Krpt. Mitt. 1905 41 226-234).- Large cube-shaped crystals measuring 16 x 19 mm.in a blast-furnace slag from the Seigerhutte a t Hettstedt near Mansfeld in Prussian Saxony have been analysed (anal. I} by W. STAHL (Berg- und Hiittennnt. Zeit. 1904 63 273-274); he described the crystalline form as cubic and was unable to identify the material. A new examination proves the crystals to be melilite and of the form common in slags. The double refraction is very feeble and negative in sign but portions of some crystaJs are isotropic ; pleochroism is distinct The crystals enclose numerous impurities.

PHYSIOLOGICAL CHEMISTRY. Physiological Chemistry. 835 Action of Oxygen on the Sickness produced by Rarefaction of the Air. Experiments on an Orang-Outang. ALBEBTO 180-187).-The symptoms observed on the respiration of air a t great altitudes are not due alone to the diminished partial pressure of the oxygen. Air rich in oxygen has a beneficial action on the sickness produced by barometric depression and up to a certain point this beneficial action is proportional t o the percentage of oxygen in the inspired air; but with very great rarefactions the symptoms are observed whatever the content of oxygen in the air (compare Mosso Abstr. 1904 ii 577 and 622). If the amount of carbon dioxide in the inspired air is increased to a certain value more considerable dilution of the air can be withstood without; injurious effects and the greater the proportion of carbon dioxide the more can the air be diluted.Carbon dioxide does not exert this beneficial action unless its partial pressure in the air exceeds 18 mm. Simultaneous Action of Oxygen and Carbon Dioxide on the Sickness produced by Rarefaction of the Air. Experiments on an Orang-Outang. ALBERTO AGGAZZOTTI ( A t t i R. Accud. Lincei 1905 [v] 14 ii 256-264. Compare Abstr. 1904 ii 746 and pre- ceding abstract).-Only air which is rich in both carbon dioxide and oxygen can alleviate the ill-effects which are produced by lowering of the barometric pressure. Experiments on a Man breathing Carbon Dioxide and Oxygen together under a Barometric Pressure of 122 mm corresponding with an Altitude of 14,582 Metres.ALBEXTO AGGAZZOTTI (Atti R. Accccd. Lkcei 1905 [v] 14 ii 290-297. Compare preceding abstracts).-The remlts obtained with the orang- outang are confirmed by those given by similar experiments with a man. A t a height of 14,500 metres man suffers no discomfort if the air breathed contains 13 per cent. of carbon dioxide and 67 per cent. of oxygen AGG-4ZZOTTI (Atti R.

Physiol. 1905 14 433-451).-The conclusion is drawn from experi- ments on heart-strips that certain agents such as the constant current induction shocks and mechanical tension which have been considered capable of producing rhythmical activity owe their power to the solution of sodium chloride used with them which therefore cannot be looked on as an indifferent fluid W.D. H. Electric Conductivity of Blood during Coagulation. ROBERT T. FRANK (Amer. J. Physiol. 1905 14 466-468).-No appreciable change occurs in the conductivity of the blood during the coagulation836 ABSTRACTS OF CHEMICAL PAPEKS. process. Whether the amount of fibrinogen in the blood is too small t o show tangible changes or whether the numerous chemical and physical changes occurring in the complex process of coagulation exactly neutralise each other could not be determined. The latter explanation appears to be unlikely. W. D. H. Osmotic Pressure of Blood and Urine in Fishes. M. C. DEKHUYZEN (Chem. Centr. 1905 ii 1035-1036 ; from Arch. N6erZaiLd [ii] 10 121-136).-Certain fish such as the salmon and eel are able to pass without inconvenience from the sea where the pressure is great into fresh water where the pressure is much lower.Estimation of the freezing points of blood and urine shows that by the regulating action of the kidneys fishes like warm-blooded animals are able to maintain the osmotic pressure of their blood a t a constant level. The osmotic pressure of the blood of warm-blooded animals varies from 6.75 to 7.25 atmospheres that of different fresh water cold-blooded animals is about 6 atmospheres that of marine fishes 8.7 atmospheres. W. D. H. Effect of Intravenous Injections of Bile on Blood-pressure. S. J. MELTZER and WILLIAM SALANT (J. exper. Ned. New York 1905 '7 380-291).-Although as previous observers have shown the influence of bile salts on blood-pressure is slight that of the entire bile is very marked leading to a great depression of the arterial pressure.The rate of injection makes a considerable difference rapid injection producing the most marked or even fatal results. The effect like that of potassium salts is mainly cardiac. I n some experiments intravascular coagulation was noticed. W. D. H. Action of Potassium Salts on the Circulatory Organs. P. TETEUS HALD (Ckem. Centr. 1905 ii 1107 ; from Arch. exp. Path. Pharm. 53 227-26O).-In rabbits injection of hypertonic solutions of potassium chloride produces a slow pulse and fall of arterial pressure ; sometimes slow but high elevations of the pulse occur. If the dose is not large enough to be immediately fatal the salt get0 into the tissues.and. after about half an hour begins to be eliminated I by the kidneys ; thus the poison is removed fromuthe body. W. D. H. Resistance of the Corpuscles of Fatal Blood. ALB. 5. J. VANDEVELDE (Chem. Centr. 1905 ii 1035 ; from Ann. S'oc. Med. Gand 85 152).-Hamburger has pointed out that the corpuscles of f e t a l blood are more resistant to saline solutions than are those of the mother. The amount of resistance to 20 per cent. alcohol amyl alcohol and absinthe (haemolytic agents) is about 5 per cent. greater than that of the maternal blood corpuscles. W. D. H. Influence of Concentration of Blood-corpuscles and the Form of the Reagent Vessel on Haemolysis by Chemical Re- agents. ALB. J. J. VANDEVELDE (Chenz.Centr. 1905 ii 1035 ; from Ann. Xoc. Med. Gand 1905 May).-The rapidity of haemolysisPHYSIOLOGICAL CHEMISTRY. 837 increases with the diameter of the vessel employed. The number of blood-corpuscles in narrow tubes has only a small influence on the rapidity of the hzmolytic reaction. W. D. H. P. MORAWITZ (Beit?.. chenz. Plqsiol. Putlh. 1905 7 153-164).-Some recent researches appear to in- dicate that the albumin of the blood is in closer relationship to the proteid in the food than the globulin which some believe is formed at the expense of the albumin. I n the present experi- ments it is shown that after extensive loss of blood the organism has the power of again forming new proteid matter for the blood even during hunger and that the reappearance of the globulin is more rapid than that of the albumin; the latter is probably retained by the organism outside the circulatory system and during inanition re-enters the blood stream.The Proteids of the Blood. W. D. H. Behaviour of Salt Solutions in the Etomach. THEODORE PFE~FFER (Chem. Centr. 1905 ii 1108-1109; from Arch. exp. Path. Pharm. 53 261-279).-Solutioas of sodium sulphate were introduced into the stomachs of dogs with an esophageal fistula so that no saliva entered the stomach. After a time the solution was withdrawn and its freezing point determined. It was found t h a t the stomach wall does not absorb the salt from either hyper- tonic or hypotonic solutions but often water passes into the stomach. The exchange of salt between blood and stomach con- tents is due t o simple diffusion.W. D. H. Examination of Gastric Contents. WILLIAM H. WILLCOX (Trans. Path. SOC. London 1905 56 250-259).-A description of methods best available for clinical use in dealing with the gastric contents. The principal tests given are those for the hydrochloric acid and organic acids if present both qualitative and quantitative. Gunzberg’s and the dimethylaminoazobenzene reactions are the best for the detection of the former acid. I n gastric and duodenal ulcer the acidity is usually high but organic acids are absent. I n temporary dyspepsia nothing note- worthy was found. I n malignant grdwths of the cardiac portion of the stomach the total acidity is small often nil; free hydrochloric acid is always absent. I n similar growths of the pyloric portion the acidity is reduced to half the normal free hydrochloric acid is scarcely ever present and organic acids are abundant.W. D. H. Digestion in Dogs with Artificial Anus. GEORG MAETZKE (Inaug. Dissert. Breslccu Univ. 1905,1-59).-1n dogs with a fistula in the ileum the outflow from the orifice commences within an hour after feeding or if much food is given within half an hour. Foreign particles (pieces of cork) cause delay. The reaction of the contents of the small intestine to phenolphthalein and turmeric is usually acid but after flesh feeding alkaline. The reaction to lacmoid and methyl-orange is alkaline except possiblyin the upper part of the duodenum. The variations noted in different regions depend on the838 ABSTRACTS OF CHEMICAL PAPERS. amount and character of the food.Trypsin diastase and invertase are found in varying quantities in the ileum. Leucine and tyrosine are not found even after large quantities of proteid food. I f the food given is not excessive the absorption of proteid sucrose and starch is very complete in the small intestine. W. D. H. The Relationship of the Peptic Digestion Products of Plasteinlr to Liver Muscles and Other Organs. 11. JOSEPH GROSSMANN (Beitv. chem. Physiol. Path. 1905 7 165-174).-Experi- ments are recorded that show that solutions of plastein-albumoses are not only changed into coagulable proteids by the mucous membrane of the alimentary tract but also by other organs such as the liver large intestine muscles and brain. W. D. H. Gastric Digestion of Proteids. HANS LEO (Zeit.physiol. Chew,. 1905 46 286-292).-Experimer,ts with fibrin tend to show that to adopt Ehrlich's nomenclature pepsin plays the part of a thermolabile amboceptor and hydrochloric acid that of a thermost,able complement in gastric digestion. W. D. H. Pancreatic Secretion. H. G. CHAPMAN (Pvoc. Linn. sbc. N. 8. Wales 1905 92-1 00)-Secretin obtained from the echidna wallaby Australian water tortoise and ibis causes a flow of pancreatic juice in the dog but apparently not in the echidna. The flow produced by pilocarpine is and that produced by secretin is not inhibited by atro- pine. Stimulation of the vagus does not inhibit secretion due to secretin. The pressure of the fluid in the pancreatic duct is equivalent to nine inches of the juice. Pancreatic juice so far as its proteolytic property is concerned can be activated by leucocytes.W. D. H. Action of Pancreatic Juice on Edestin from Cotton Seeds. EMIL ABDERHALDEN and BELA REINBOLD (Zeit. pl~ysiol. Chem. 1905 46 159-175),-The various crystalline products obtained after the digestion of edestin (from cot ton seeds) were separated and identified in the usual way. The opinion is supported that the object of diges- tion is to break down a '' foreign proteid " into simple cleavage pro- ducts and that this is essential to enable an animal to synthesise the proteids specific to itself. W. D. H. Chemistry of Digestion in Animals. 11. Digestion of Pro- bids in the Alimentary Tract E. s. LONDON and A. TH. SULIMA (Zeit. physiol. Chem. 1905 46 209-235).-Fistulae were made in various positions of the alimentary tract in dogs and proteids of different kinds given as food.The examination of the contents of the canal in different situations and a t different intervals after digestion (for albumoses peptones crystalline cleavage products &c.) allows conclusions to be drawn regarding the site and time relationships of digestion and absorption in different parts of the gastro-intestinal traet. W. D. H.PHYSIOLOGICAL CHEMISTRY. 839 Proteid-katabolism. OTTO COHNHEIM (Zeit. physiol. Chem. 1905 46 9-l6).-The experiments were made on a dog with a Pawloff’s gastric fistula. For several days the animal was given nothing but salt and water ; on some days it underwent the process of ‘‘ sham feed- jng,” which Pawloff has shown causes an abundant flow of gastric juice.But the activity of the digestive organs in itself has no in- fluence on the amount of urinary nitrogen. Cage for Metabolism Experiments WILLIAM J. GIES (Amer. J. Physiol. 1905 14 403-410).-An illustrated description of an animal cage with various devices for collecting excreta &c. during metabolism experiments. W. D. H. Behaviour of Glycyl-Z-tyrosine in the Dog’s Organism after Subcutaneous Injection. EMIL ABDERHALDEN and PETER RONA (Zeit. physiol. Chem. 1905,46 176-178).-Uertain polypeptides are easily resolved by whilst others resist the action of pancreatic juice. It was therefore interesting to know what happens to them when introduced parenterally that is without the intervention of the digestive juices for instance by subcutaneous administration. Ac- cordingly glycyl-Z-tyrosine was prepared by Fischer’s method ; this is a dipeptide which is easily resolved by trypsin.It is also com- pletely split up after subcutaneous injection both glycine and tyrosine being noticeable in She urine. Behaviour of Cystine Dialanylcystine and Dileucylcystine in the Organism of the Dog. EMIL\ ABDERHALDEN and FRANZ SAMUELY (Zeit. physiol. Chem. 1905 46 187-192).-The cystine peptides are easily split up by pancreatic juice; the two mentioned were prepared by Fischer’s method and their behaviour compared with that of cystine from horse-hair. The administration mas in some cases with the food in others by subcutaneous injection. By either method cystine increases the amount of oxidised and neutral sulphur in the urine ; the dipeptides behave in exactly the same way.The increased amount of sulphur practically accounts for all the cystine given either alone or in combination. The rncernic peptides (leucyl- leucine leucylglycine &c.) are similarly broken up. WILLIAM H. THOMPSON (J. Phy&oZ. 1905 33 106-124. Compare this vol. ii 268).-1f dogs are fed on arginine the proportion of its nitrogen which reappears as urea varies from 37 to 77 per cent. Part of this is excreted at once part more slowly the latter being probably formed by deamidation of the ornith- ine moiety and subsequent synthesis of the ammonia into urea. If the arginine is given subcutaneously the yield of urea-nitrogen is larger. The effects cannot be explained as the result of the solvent (0.9 per cent.sodium chloride) used. The amount of nitrogen excreted as ammonia varies but aberages 10 per cent. of the arginine-nitrogen given. Ornithine putrescine or arginine do not appear as such in urine or fzeces. In some experiments alarge deficit of nitrogen (37 to 59 per cent.) is accounted for by retention in the body as protoplasm. W. D. H. W. D. H. W. D. H. Metabolism of Arginine. W. D. H.840 ABSTRACTS OF CHEMICAL PA I’ERY. Metabolism (Albuminous and Saline) in Man. GEORG YON WENDT (Chem. Centr. 1905 ii 1109; from Skand. Arch. Physiol. 17 211-289).-Among the many points raised in this paper are the following the excretion of sulphur is a better measure of proteid katabolism than that of nitrogen ; exogenous is distinguished from endogenous metabolism in relation to purine bases sulphur and other substances.The relative constancy of endogenous metabolism is established ; the sparing action of non-nitrogenous foods is illustrated ; the exishence of an “internal circulation ” in cell metabolism is suggested. W. D. H. Assimilation of Nitrogen Phosphorus Calcium and Mag- nesium in Man. E. GUMPERT (Chem. Centr. 1905 ii 1036 ; from Med. KZinik. 1 1037-104 I).-A metabolic comparison of the effects of feeding on “sanatogen” with other forms of diet; some small differences in detail are noticeable. W. D. H. Assimilation of Proteid in Animals. EMIL ABDERHALDEN and FRANZ SAMUELY (Zeit. physio2. Chem. 1905,46,193-200).-Recent re- search shows that the proteids peculiar to each animal are built up from the simple cleavage products of the proteid in the diet.The biological reaction shows the absence of any foreign proteid in the blood. A horse mas bled and after a hunger interval was fed on gliadin which yields 36.5 of gluhilmic acid and 2.37 o€ tyrosine per cent. These numbers are very different from those obtained from the normal proteids of serum. But in the serum proteids of the new blood the horse made the proportion of these products remained the same and was not influenced by the different proportion in the food-proteid. It is not improbable that the liver as well as the intestinal wall plays a part in proteid synthesis. IT7. D. H. Vegetarianism. WILHELM CASPARI (Psiiger’s Arcl~iv 1905 109 473-595). -A very complete study of the subject from several points of view. In the portion dealing with new researches several experi- ments were made on human beings and a complete record kept of their metabolic history. The most severe experiment lasted for ninety-six days on a man who weighed 53 kilos,; a t the end of the time he weighed 40 kilos.and in his photograph appears like a skeleton ; his main diet mas apples and grapes. A pure vegetarian diet is inappropriate because (1) it is bsdly absorbed especially so far as proteids are concerned ; (2) it is irritative t o the alimentary canal ; and (3) because of its large volume. These evils can t o a certain extent be overcome by the use of certain preparations but the small proteid intake appears t o be insuperable. W. D. H. Autolysis. 0. ScHvimi (Beitr. cherra. I’hysiol. Path. 1905 7 175-203).-Details are given of the products of autolysis in the tissues (especially spleen and bone marrow) of cases of leucaemia.In this disease a proteolyt ic ferment occurs in the blood which resembles trypsin in its activities not pepsin as in some cases of this disease. W. D. H.PHYSIOLOGICAL CHEMISTRY. 841 The Condition of Living Substance. HUGO FISCHER (Zeit. physiol. Chem. 1905 46 206-208).-Polemical against E. Buchner on the nature of the chemical processes OF life and as to how far the action of enzymes is to be considered a portion of the chemistry of life (compare Biicliner and Antoni this vol. ii 472). W. D. H. Cholesterol Esters in the Brain. R. BUNZ (Zeit. physiol. Chem. 1905 46 47-51).-Baumstark (Abstr. 1885 918) stated that the brain contains not only cholesterol but cholesterol esters as well.I n the present research this is not confirmed; the ethereal extract contains no esters of cholesterol with higher fatty acids or.any other compounds of cholesterol from which cholesterol is separated by saponification. W. D. H. The Ereptic Power of Tissues as a Measure of Functional Capacity. HORACE M. VERNON ( J . Physiol. 1905 33 81-loo).- The erepsin in the tissues of guinea-pig cat and rabbit increases in utero and for a few days after birth ; then it remains constant. The increase is 5- or even 10-fold in kidney and liver but slight in muscle. Feeding with meat in cats doubles the amount in spleen and liver but does not affect other tissues. The distribution of erepsinin the ali- mentary canal is unequal; on a mixed or meat diet in cats the duodenum is richest in the ferment ; on a bread and milk diet this falls and the amount in the large intestine rises. I n the herbivorous rabbit the alimentary canal is altogether poorer in erepsin especially in the duodenum.Hibernat,ion lessens the erepsin in spleen liver and kidney but not in brain or muscle. Disease if accompanied by wasting has the same effect. W. D. H. Mytolin a Proteid from Muscle. W. HEUBNER (Chem. Centr. 1905 ii 1106 ; from Awh. exp. Path. Phrm. 53 302-312).-From rigored horse-flesh ammonia or 10 per cent. sodium chloride solution extracts a proteid matter named mgtolin. When by dialysis the con- centration of the salt solution is reduced to 2-3 per cent. it is pre- cipitated in a comparatively insoluble form. By further dialysis a globulin is precipitated.By the action of carbon dioxide and repeated solution in very dilute sodium carbonate a part of the globulin is transformed into mytolin. Neutralisation of a saline extract of muscle precipitates mytolin but leaves the globulin in solution. W. D. H. Hexone Bases of Liver Tissue. ALFRED J. WAKEMAN (J. exper. Ned. New York 1905 7 292-307. Coinpare this vol. ii 467).-The results reported show that in degenerating liver tissue chemical changes in the cells lead to a diminution of the hexone bases but especially of arginine. How much arginine passes into the urine or is acted upon by arginase is uncertain. The changes during degeneration have the same general direction as in post-nsortena autolysis. W. D. H.842 ABSTRACTS OF CHEMICAL PAPERS.Grafting of the Thymus in Animals. LEONARD S. DUDGEON and A. E. RUSSELL (Trans. Path. SOC. London 1905 56 238-250).- T’he experiments were undertaken with the idea of observing whether grafting of the thymus gland would produce any alteration in the blood or any condition resembling lymphatism in which the thymus is known to play a part. Lanocerin. FRANZ ROHMANN (Zenty. Physiol. 1905 19 317-320).-Lanocerin is the name given to a new constituent of wool-fat from which it can be prepared by boiling with methyl alcohol and then eutractingithe residue with ether. It is precipitated from this solution by alcohol. By boiling with alcoholic potash the potassium salt of lanoceric acid (Darmstiidter and Lipschutz Abstr. 1896 i 522) is obtained.Lanocerin is an inner anhydride of this acid. The carnaubic acid of the same authors (Abstr. 1896 i 346; 1897 i 180) is probably an impure product. The sebaceous glands yield a substance named dermocevin the nature of which is uncertain. The anal glands do not secrete cholesterol but an ester of octadecyl alcohol named pennacerin. The relationship of such substances to cholesterol and oleic acid is discussed. The results were negative. W. D. H. W. D. H. Local Anesthesia produced by Alypin. E. IMPENS (P’iiger’s Archiu 1905 110 21-87).-The hydrochloride of alypin [tetra- methyldiaminoethyldimethylcarbinyl benzoate OBZ*CE~(CH,*NM~,)~] is recommended as a local anasthetic; it is at least as powerful as cocaine and much less toxic. It does not produce mydriasis or any interference with accommodation.W. D. H. Contractile Mechanism of the Gall-bladder. FRANCIS A. BAIN- BRIDGE and H. H. DALE (J. Physiol. 1905 33 138-155).-The rhythmic contractions of the gall-bladder are increased by section of the splanchnic nerves or by the intravenous injection of chrysotoxin. Stimulation of these nerves or injection of adrenaline causes relaxa- tion. The vagus contains motor fibres which are paralysed by atropine. Bile salts amyl nitrite and atropine cause relaxation ; pilocarpine and peptone cause an apparent contraction due to the mechanical effect of swelling of the liver. The anaemia caused by compression of the aorta produces a rapid fall in the tone of the muscle of the gall-bladder. A New Nitrogenous Constituent of Normal Human Urine.PAUL H ~ R I (Zeit. physiol. Chem. 1905 46 1-8).-The zinc silver and cadmium compounds of a new constituent of the urine precipit- able therefrom by a 10 per cent. solution of phosphotungstic acid were prepared and analysed. It contains carbon hydrogen nitrogen and oxygen but has not yet been isolated from its metallic compounds. It is not urobilin but appears to have a possible relationship to Garrod’s urochrome. W. D. H. W. D. H. Excretion of Sugar after Administration of Alanine in Dogs without a Pancreas. MARCO ALMAGIA and GUSTAV EMBEN (Beitr. chem. Physiol. Path. 1905 7 298-310).-After extirpation of thePHYSIOLOGICAL CHEMISTRY. 843 pancreas the sugar which appears in the urine is considered to originate solely from carbohydrate material which is newly formed in the body.Alanine produces such a new formation of carbohydrates. W. D. H. Precipitability of Carbohydrates in Urine by Lead Acetate. OSCAR ADLER and RUDOLF ADLER (PJtiiyeds Archiv 1905 110 99-103. Compare this vol. ii 337).-Proofs are adduced that hvulose may occur in the urine and is partially precipitated (like arabinose and dextrose) by lead acebate. W. D. H. A Non-dialysable Proteid-like Constituent of Human Urine. EMIL ABDERHALDEN and FRITZ PREGL (Zeit. physiol. Chem. 1905 46 19-23. Compare this vol. ii 467).-Urine contains a substance which yields glycine and phenylalsnine on decomposition and appears to belong to the polypeptides. W. D. H. The Globulin of Albuminous Urine. A. W. SIKES (J. Physiol. 1905 33 101-105).-1n albuminous urine the globulin increases somewhat on keeping at the expense of the albumin.The change occurs more readily in alkaline urine and is probably not due to bacterial action. Albumose added to globulin solutions does not increase the amount of the latter substance. Electrical currents passed through the urine increase the globulin probably by heating the urine. W. D. H. The Chromogen of so-called Scatole-red in Normal Human Urine. J. PH. STAAL (Zeit. physiol. Chem. 1905 46 236-262)- The chromogen of the so-called scatole-red in normal human urine is not a conjugated sulphate (for instance of glycuronic acid). It is not a derivative of scatole in the chemical sense of that term but is iden- tical with the urorosein of Nencki and Sieber. W. D. H. A Prehistoric Egyptian Calculus.SAMUEL G. SHATTOCK (Trans. Pat?h. Xoc. Lo?zdon 1905 56 275-290).-l'he examination of the calculus which was obtained from a tomb of date 4800 B.c. showed it t o consist of uric acid coated with phosphates; calcium oxalate was absent. A second calculus probably renal and 600 years later in date was found to consist of calcium carbonate phosphate and oxalate. The paper contains much of archzological interest especially with regard to the diseases and diet of the ancient Egyptians.

The second stone however contained numerous mould conidia but attempts to cultivate these mere fruitless. W. D. H. Virulence and Immunising Power of Micro-organisms.RICHARD P. STRONG (J. Exper. Ned. New York 1905 7 229-264). -From experiments on two strains of cholera vibrio differing in virulence it is shown that the number or the avidity of the bacterio-844 ABSTRACTS OF CIIEMICBL PAPERS. lytic receptors possessed by a bacterium is proportional to its virulence. The agglutinable receptors are not necessarily present in the same pro- portion. The virulent organism possesses more toxic haptophore groups than the avirulent. Immunity produced by injecting dead organisms is proportional to their original virulence but if the living organisms are used the proportion is not so di:ect. W. D. H. Stimulins. W. B. LEISHMAN (Trans. P&. S'oc. London 1905 56 344-355).-The favouring effect of the addition of immune serum on the phagocytic action of leucocytes was originally attributed by Metschnikoff to a stimulating effect on the leucocytes and the term stimulin was coined by him as a name for the substance in the serum t o which theeffect is due.I n the present experiments serum from cases of Malta fever and typhoid fever (but not normal serum) was found to possess the power of increasing the phagocytic activity of the leucocytes on the specific bacilli of those diseases. These substances are thermostable withstanding a temperature of 60" for fifteen minutes. The inc:eased phagocytosis may be in part due to the presence of agglutinins or of immune substance in the serum. The view is held that the main effect is a stimulating one on the leucocytes and not due to the addition of an opsonin to the bacilli.Wright's hitherto described opsonins are destroyed by a temperature of 60'. It is how- ever admitted that there may bea class of opsoiiins which are thermo- stable a view Metschnikoff appears now also inclined to accept. W. D. H [Glycosuria]. EDUARD PFLUGER (Pjiiyer's Archiv 1905,110,1-20). -Polemical against Minkowski. W. D. H. Experimental Glycosuria. FRANK P. UNDERHILL (J. Biol. CJAem. New York 1905 1 113-130. Compare this vol. ii lS7).- The glycsmia provoked by piperidine pyridine coniine curare nicotine morphine ether chloroform carbon monoxide pyrogallol &c. is not due to any specific action on any particular o r p n such as the pancreas but to their action in producing dysyncen. If oxygen is also administered it does not appear.Adrenaline diabetes cannot how- ever be explained in this way. I N . D. H. Opsonic Content of Blood Serum in Health and in Lupus. WILLIAM BULLOCK (Trans. Path. SOC. London 1905 56 334-344).- Films made from blood mixed with tubercle bacilli were prepared and examined according to Wright's technique. The bacilli are counted in the leucocytes and an average per leucocyte struck. If this is done after admixture with (1) an abnormal and (2) a normal serum the aver- age for leucocyte in the first case divided by that in the second is called the opsonic index. I n S6 healthy people the index was 0.97 the extremes being 0.8 and 1.2. I n tuberculosis of the skin (lupus) the average was 0.75 in 150 cases I n 75 per cent. of these the index was below the lowest normal limit 0.8 and in 27 cases below 0.5; in 3 cases as low as 0-2.If the index is well below the normal Finsen light treatment is of little or no benefit. The ultra-PHYSIOLOGICAL CHEMISTRY. 845 violet rays have but little penetrative power and probably exert no potent effect on tubercle bacilli. The healing properties in cases with high opsonic index are due to a reaction set up in the tissues and to the congestion and exudation that follow exposure to the rays. W. D. H. Behaviour of Leucocytes in Malignant Growths. J. E. FARMER J. E. S. MOORE and C. E. WALKER (Trans. Path. Xoc. London 1905,56 377-380).-1n the early stages of a cancerous growth there is marked activity among and increase of leucocytes and there is evidence that the new growth does not originate from a single cell or even from a few cells but is evolved by the direct conversion of normal cells into those of a malignant type.The tissue cells take up the leucocytes but neither are injuriously a.ffected or eventually destroyed and both continue to divide mitotically; both nuclei pass through the mitotic evoliition either on separate spindles or the spindle figures may become confused as occurs in the first cleavage of the ovum. The two sets of chromosomes are confusedly distributed between the daughter nuclei and the process may thus be compared to fertilisation. The reduction of chromosomes so characteristic of neoplastic cells must occur later. W. D. H. Metabolism in Osteomalacia. J. E. GOLDTHWAIT C. F. PAINTER R. B. OSGOOD and FRANCIS H.MCCRUDDEN (Amer. J. Phpiol. 1905 14 389-402).-Metabolism experiments on a girl aged sixteen suffer- ing from osteomalacia were carried out during tmo periods (1) before and (2) after castration. There is first a decalcification of the bony tissue; the calcium is replaced partly by magnesium but probably chiefly by an organic substance rich in sulphur,*but poor in phosphorus similar to but not exactly like the normal organic matrix. Castration checks the progress of the disease and the lost bony material is re- placed. W. D. H. The Opsonic Index in Phthisis. HAROLD MEAKIN and CHARLES E. WHEELER (Brit. Med. S. 1905 ii 1396-1397).-The observations show the great variations in opsonic index in cases of pulmonary tuberculosis and even in the same case especially during the early stages of the disease.When the case becomes chronic the opsonic index is fairly stationary; if it is then one or over prognosis is better than when it is below unity. Enzymes and Anti-enzymes of Exudates. EUGENE L. OPIE (J. Exper. Med. New York 1905 7 316-334).-The serum of an inflsmmary exudate inhibits the action of the proteolytic enzymes contained in the leucocytes ; the anti-enzyme doubtless Fasses from the blood into the exudation. I n late stages of inflammation this inhibit- ing action is lessened. The anti-enzyme is destroyed by heating at 75". The proteolytic enzymes of the leucocytes act in both an acid and alkaline medium but are more efficient in the latter. The action of the anti-enzyme is favoured by an alkaline and completely lost in an acid medium.W. D. H. W. D. H. VOL. LXXXVIII. ii. 58846 ABSTRACTS OF CHEMICAL PAPERS. [Physiological] Action of Barium Chloride and of Barutine. H. BRAT (Chem. Geyztis. 1905 ii 1189 ; from Bed. klirn. f%ch. 42 1229-1225).-“ Barutine ” is the double salt formed by the combina- tion of barium theobromine with sodium salicylate. It is a white crystalline powder and is soluble in water. Barium tlieobromine pre- pared by the action of barium chloride on sodium theobromine is insoluble in water. The preparation contains 9.5 per cent. of barium 25.5 of theobromine 50 of sodium salicylate and about 10 of water and sodium chloride; since it is faintly alkaline i t requires to be kept in an atmosphere free from carbon dioxide. Whilst a dose of 0.113 gram of barium chloride per kilogram of body-weight is fatal to dogs when administered either internally or eubcutaneousl y barutine is a t least nine times less poisonous.Experiments on t,he physiological action and therapeutic application of bariitine as a diuretic have also been made. E. W. W. Action of Adrenaline on Cerebral Vessels. CARL J. WIGGERS (Anzer. J. Physiol. 1905 14 452-465).-Perfusing the isolated brain under constant pressure and temperature and recording the venous outflow was the method adopted. Addition of adrenaline to the perfusion fluid lessens the outflow owing no doubt to constriction of the vessels which the drug produces here as elsewhere. The existence of vaso-motor nerves in the cerebral blood-vessels is thus proved experimentally. W. D. H.Action of Synthetical Substances allied to Adrenaline. OTTO LOEWI and HANS %%EYER (Chena. Ceilztr. 1905 ii 1111-1112; from Arch. exp. Pccth. Phama. 53 213-226) -Stolz’s methylamino- acetylcatechol probably the corresponding ketone to adrenaline has a similar but weaker physiological adion. Of Stolz’s other products the simple amino-ketones show the strongest action bhat of the ethyl being more marked than that of the methyl compound. Dialkylamino-ketones monoethanolamino-ketones and phen ylaminoacetylcatcchol are inactive ; piperidinoncetylcatechol has only a weak action Reduction of the amino- ketone produces an amino-alcohol not yet obtained pure but similar to adrenaline. The active products like adrenaline act on blood pressure respiration and the iris muscles and produce diabetes.Given sub- cutaneously they also cause the same results. Hydrochlorides of some of these bases were prepared in crystalline form. W. D. H. Hippuric Acid Synthesis. WILHELM WIECHOWSKI (Beitr. chem. Physiol. Patlb. 1905 7 204-272).-A study of the pharmacological action of benzoic acid given in various ways to rabbits. The amount given is not wholly excreted as hippuric or benzoic acids; the longer i t remains in the body the greater is the amount of hippuric acid synthetically formed. Glycine as an intermediate metabolic product is considered at some length. More than half the urea-nitrogen is believed to pass through the glycine stage. Descriptions of analytical methods and references to literature are given in full. W. D. H.VEGETABLE PHYSIOLOGY AND AGRICULTURE.847 Physiological Action of Physostigmine. W. HEUBNER (C'?benz. Centr. 1905 ii 1111 ; from Arch. exp. Pat?h. Yharz. 53 313-330). -Experiments on frogs mammals and man show that no immunity can be produced to physostigmine. I n a dog that received 60 mg. in 19 days only 2 mg. were recovered in the urine. Physostigmine- blue a derivative of physostigmine is not poisonous in small doses ; larger doses paralyse the heart and central nervous system in frogs. Another derivative rubreserin is inactive. The alkaloid itself has the constitution NHMe*CO*NH*C'!,H~,N.OH. It splits into eseroline and rubreserin; the latter in alkaline solution is changed into physo- stigmine-blue the composition of which is unknown. It forms brown amorphous products on drying and evaporation. W. D. H. Influence of Thyroid Feeding on Poisoning by Aceto- nitrile. REID HUNT (J. Biol. Chem. 1905 1 33-44).-Proteids increase the susceptibility of mice to acetonitrile whilst thyroid feeding (and potassium iodide to a slight extent) decreases it. Thyroid has no antagonistic action towards sodium nitroprusside or free hydro- cyanic acid. Feeding on parathyroids has the opposite effect to thyroid feeding. W. D. H. Action of Certain Poisons on the Isolated Small Intes- tine of Dogs and Rabbits. K. KRESS (P'iiger's Archiv 1905 109 608-620).-The work was carried on by Mngnus' method. Nicotine causes first inhibition then stimulation ; larger doses produce paralysis. Certain differences are noticeable in detail in different animals. Atropine in the cat but not in the dog or rabbit acts antagonistically to nicotine. There are also differences in the antagon- istic actions of physostigmine and atropine and of pilocarpino and atropine. The action of a number of other poisons (strophanthine apocodeine barium chloride adrenaline &c.) was also studied. W. D. H. Isoform a New Antiseptic. BERNIIARD HEILE ( TToZkrrmzds Sammlung klin.

Fusel oils produced from different materials are very similar and contain besides amyl alcohol considerable amounts of propyl and isobutyl alcohols and small amounts of other alcohols. Normal butyl alcohol is not present. All bacteria which produce higher alcohols produce normal butyl alcohol whilst arnyl alcohol has not been detected.Emmerling's potato bacteria produces prirpyl alcohol the potato bacillus isopropyl slcohol Grimbert's 13. orthobutyricus isobutyl alcohol whilst a number of bacteria produce norinal butyl alcohol together with butyric acid. Bacteria which produce alcohols (except Winogradski's Glostridium Pasteuriaizum) produce far more ba tyric acid than corresponds with the composit,ion of fusel oil. The view t h a t fusel oil is produced by bacteria is therefore incorrect ; the higher alcohols are probably formed by the decomposition of yeast- pro t eid. HANS H. PRINGSREIRZ (Centr. Bakt.

Spiritusind. 1905 No. 26-29).-The bacilli from mash cultures heated at 51' failed to grow both at higher and lower temperatures being weakened chiefly by the acid present.In presence of calcium carbonate no weakening was observed. Cultures heated a t 38' with- out calcium cnrbonate showed a good growth after four days although 1.2 per cent. of lactic acid mas present. The mash which had been heated at 51' contained 0.9 per cent. of acid. The weakening is therefore due both to acid and to the high temperature. The greater the number of cells sown the greater the development and the shorter the cells. The length of the cells is also affected by the temperature ; at 50' the cells are short at 40° much longer whilst at 30' the cells are extremely long. N. H. J. M. Influence of Temperature on the Assimilation of Carbon Dioxide. ARISTIDES KANITZ (Zeit. Elektrochem. 1905,11,689-690). -From the experiments of M.atthaei (Abstr.1904 ii 70) it is shown that the rate of assimilation of carbon dioxide by green leavesVEGETABLE PHYSIOLOGY AND AGRICULTURE. 849 increases with the temperature in the ratio commonly found for chemical reactions.

T. E. Physiological Processes of Green Leaves with Special Reference to the Interchange of Energy between the Leaf and its Surroundings HORACE T. BROWN and FERGUSSON ESCOMBE (Proc. Rog. Soc. 1905 B 78 29-111. Compare Abstr. 1909 ii 682).-The rate of carbohydrate formation (assimilation) in a leaf surrounded by an atmosphere containing about the normal proportion of carbon dioxide (0.03 per cent.) is determined by passing a known volume of air over the leaf and finding by analysis the proportion of carbon dioxide present before and after the experiment.Since one part by weight of carbon dioxide corresponds with about 0.64 part by weight of carbohydrate the amount of the latter produced in a given time can readily be calculated. The results obtained by this method are much lower than those deduced by Sachs' method (determination of the variations in dry weight of known areas of leaf lamina) and the authors from their experiments draw the conclusion that there are inherent errors in the latter method which render it unsuitable for determining the rate of assimilation. As an illustration of the results obtained it was found that a sun- flower leaf exposed to strong diffused light assimilated 0.00392 gram of carbohydrate per square decimetre per hour.The rate of assimila- tion under similar conditions is about 45 per cent. greater in detached than in attached leaves; this is due in all probability to the stomata being more widely open in the former case. The question of the energy relations of the leaf is fully discussed. For this purpose it is necessary to know the amount of solar energy incident on the leaf the amount absorbed and the amount of heat lost by radiation convection kc. in unit time as well as the energy changes associated with the more important physical and chemical changes going on in the leaf such as the evaporation of water carbohydrate formation and the process of respiration. The influence of the rate of motion of the air on some of these factors is taken into account.The incident solar energy is measured by a Callendar radiometer and recorder and the proportion absorbed determined with the same instruments by interposing the leaf and measuring the amount trans- mitted. The amount of heat developed in respiration is calculated from the amount of carbon dioxide given off on the assumption that carbohydrates are undergoing oxidation (Brown and Morris Trans.,850 ABSTRACTS OF CHEMlCAL PAPERS 1893 63 671). The energy absorbed in assimilation is calculated from the amount of carbon dioxide absorbed and the average heat of formation of the synthesised carbohydrates. The energy used up i n the vaporisation of water is calculated from the amount of vapour evolved in a given timo (determined directly) and the latent heat of yaporisation.The following results obtained with a sunflower leaf illustrate the relative magnitudes of these factors Energy usedfor assimilation . . . 0.66 vaporisation of water . . 48.39 Total energy expended in internal work 49.05 Solar radiant energy transmitted by leaf 3 1 -40 Energy lost by radiation convection &c . 19.55 Total incident energy . . . . . . 100.00 The leaf is therefore a very wasteful transformer of energy as in the example quoted only 0.66 per cent. is used for the production of formative material. When the solar energy absorbed is greater than the energy ex- pended in internal work the leaf comes to equilibrium a t a temperature higher than its surroundings. The temperature difference can be found by dividing the energy lost by radiation convection &c.by the ‘< thermal emissivity ” of the leaf (the energy lost by radiation con- vection &c. when the Iesf is a t a temperature loabove its surroundings) a special method for determining the latter factor having been devised. When owing to active transpiration the energy expended in internal work is greater than the solar energy absorbed the leaf takes up heat from the atmosphere and comes to equilibrium a t a temperature slightly lower than that of its surroundings. The solar energy can be reduced to a fraction of its value without seriously affecting the rate of assimilation so that even in diffused daylight the available energy is more than sufficient to give the maxi- mum effect ; assimilation is under ordinary conditions limited by tho small concentration of the carbon dioxide.Tables showing the distribution of the energy under varying con- ditions are given in the paper.

EUGBNE CHARABOT and ALEXANDRE H~BERT (Bull. SOC. chim. 1905 [ G I 33 1121-1128. Compare Abstr. 1904 ii 837).-The authors have iuvestigated the changes induced both in the amount and nature of the volatile oil produced by the sweet basil (Ocimum busilicum) as the result of systematically removing the flowers as these appear on the plant.The results are tabulated in the original and show that the removal of the inflorescence leads (1) to an increase in the size of the stem of the plant (2) to an increase inVEGETABLE PHYSIOLOGY AND AGRICULTURE. 851 the amount of oil produced per unit weight of plant substance and (3) that the processes of fertilisation and fructification lead to the consumption of some of tho odorous constituerits or of intermediate substances from which these are produced.

Porphyrcc from which the Japanese vegetable isinglass '' Nori " is prepared and Gelidium which yields agar-agar both give i-galactose and d-galactose these anhydrides being also found in the products nori and agar-agar. The authors have examined samples of edible birds' nests and find that they contain but small quantities of substances which yield reducing sugars only fructose being identified with certainty. The nests contained from 50 to 60 per cent.of nitrogenous substances resembling mucin and i t is perfectly legitimate to conclude that edible bird nests are produced from the vomit of sea-swallows. W. P. S. Constituents of the Fruits of Gopaifera Mopane. CARL MAI and C. RATH (Arch. Pha~m. 1905 243 426-430).-Chloroform extracts from the seeds a balsam with the acid number 57.4 and saponitication number 212. From this a small quantity of a substance crystallised which melts a t 96" is free from nitrogen and metals and contains C 74.7 H 11.5 per cent. From an ethereal solution of the residual balsam 5 per cent. aqueous sodium carbonate extracted acids of which the lead salts were in part soluble in ether; the acid corre- sponding to this portion was amorphous and formed a barium salt which contained Ba 36.1 per cent.The residual balsam was then hydrolysed with 5 per cent. potassium hydroxide solution and the acids liberated ; of these one fraction crystallised from 70 per cent. alcohol and melted at 77" biit was not homogeneous ; the residue was not homogeneous either. C. F. B. Root of Rheum Rhaponticum. ALEXANDER TSCHIRCH and U. CBISTOFOLETTI (Arch. Plmrm. 1905 243 443-457. Compare Hesse Abstr. 1900 i 41 and Gilson Bull. acad. voy. mSd. Belg. 1903).-The powdered root of Rheum rhaponticum of Austrian origin was extracted with 70 per cent. alcohol and the extract evaporated t o small bulk and then extracted with ether. During the last operation a substance separated identical with the substance described originally by Hornemann as riiaponticin (Hesse's rhapontin ; Gilson's ponticin).This melts'at 231° has the composition C,,H,,O = OMe*C,,H,,O,(OH) forms a diacetyll derivative melting at 138" gives an odour of oil of bitter almonds when it is warmed ou a watch-glass with diIute nitric852 ABSTRACTS OF CHEMICATi PAPERS. acid and is hydrolysed when heated cautiously with dilute sulphurio acid to dextrose and rhapontigenin (Gilson) ; it does not yield chrysamic acid when treated with nitric acid. Rhapontigenin has the composition C17H2,0 = OMe- C,,HI7(OH) ; its dibenxoyl and diacetyl derivatives melt a t 145-146' and 110-112' respectively. The ethereal extract was evaporated and the residue digested with cold 10 per cent. aqueous sodium carbonate. Chrysophanic acid remained undissolved melting at 181-182' and still containing 1.48 per cent.of methoxyl (for the substance which is completely freed from methoxyl 5 8-dihydroxy-1-methylanthraquinone which melts at 196' the name of chrysophunol is proposed). From the alkaline solution a yellow substance C,,H,,O,~= OMe*C,,H,,O melting a t 2 16' is obt,ained ; this is presumably a da~~ydroxymethoxymelhyltetrahy~rounthrcc- quinone. The liquid remaining after the extraction with ether was hydro- lysed with 3 per cent. alcoholic potassium hydroxide. The products were rheum-red rheonigrin dextrose and an orange-red dihydroxy- dimethyltetruhydroanthrapuilzo..lze ClsH,,O which melts a t 195-1 96' and forms a yellow diacetyl derivative melting at 205'. After extraction with 70 per cent. aloohol the material was extracted with 95 per cent.alcohol which dissolved chrysophanic acid and an anthraglucoside which yielded d-glucose and dihydroxydimethyltetra- hydroanthraquinone. From a sample of the roots cultivated in Berne dihydroxymethoxy- methyltetrahydroanthraquinone emodin and rhein could not be isolated and anthraglucosides were present only in small amount. Neither emodin nor rhein could be detected. C. F. €3. The Existence of a Cyanogenetic Compound in Thalictrum Aquilegifolium. LEOPOLD VAN ITALLIE (J. Pharnt. Chim. [vi] 22 337-338).-The leaves of I'halictrum aquilegifoliurn contain a glucoside resembling phaseolunatin (compare Dunstan and Henry Abstr. 1904 ii 71) for on hydrolysis with emulsin it yields hydrogen cyanide and acetone ono kilogram of the leaves producing 0.502 to 0.6 gram of hydrogen cyanide.The leaves of Thalictruna flavurn T. minus or 27. glaucuum do not furnish hydrogen cyanide under the same conditions. M. A. W. Chemistry of the Scleroderms. MAX BAMBERGER and ANTON LANDSIEDL (Monntsh. 1905 26 1109-1 118. Compare Abstr. 1903 ii 567).-Unripe specimens of Lycoperdon 6ovista from the Pitztal in Tyrol were extracted with 96 per cent. alcohol at the ordinary tem- perature and again at the boiling point.

With silver nitrate in aqueous solution it forms a transparent jelly or in dilute solution a flocculent precipitate which becomes opaque on addition of baryta water; on addition of lead acetate the aqueous solution becomes opaque and in presence of a small quantity of ammonia forms a white flocculent precipitate ; with phosphotungstic acid in very dilute sulphuric acid solution the substance forms a yellow flocculent precipitate. The second extract yielded ( a ) two substances melting at 158-159" and 163.5-164' respectively which are closely related t o ergosterol (compare Hofmann Inazbg.Biss.

G. Y. Measure for the Action of Poisons on Plants. EDUARU VERSCHAFFELT (Chem. C e i ~ t ~ . 1905 ii 1033 ; from Arch.Nikrlccwi ij 10 l-'/).-The fact that a dead cell does not increase but rather decreases in weight in water is utilised as a means of measuring the external influences suficient to cause the death of cells. The poisonous limit of copper sulphate after twenty-four hours' action on potato starch is between 0.03 and 0.05 per cent. Sodium chloride is poisonous in 2.34 per cent. solutions whilst 1.75 per cent. is without action; in the c:tse of parts of inangolds the strength has t o be 3-5 times as great t o exert a poisonous action. Potassium bromide and nitrate resemble sodium chloride ; dextrose and sucrose act similarly in only slightly greater concentration. Addition of certain amounts of sodium chloride diminish the poisonous action of quinine hydrochloride whilst larger amounts increase the poisonous action.The poisonous action of oxnlic acid is partially neutralised by sodium chloride and also in a less degree by sucrose. N. H. J. M. Insensibility of Higher Plants towards their own Poisons. G. J. STRACKE (Chenz. Centr. 1905 ii 1033-1034; from rl?*ch. Nzerland [ ii] 10 8-61).-Tissues of higher plants may be insensible towards their own poisons but this is not always the case. The same cells may be insensible towards other poisons than those to which they are accustomed. It is probable that in some cases poisonous liquids obtained from plants only become poisonous after their separntion owing to the action of enzymes. Of the various acids investigated the most poisonous are hydro- chloric and oxalic acids ; the less poisonous acids tartaric citric malic and lactic acids are about equal among themselves.Alkaloids are only slightly poisonous towards higher plants ; the most poisonous is quinine hydrochloride and strychnine hydrochloride is more poisonous than the nitrate.

Leipxig Heft 7 1-103).-The decomposition of bone meal varies least according to the time of the year ; nitrification denitrifi- cation and assimilation are more influenced whilst the effect of season is most marked in the decomposition of urea and calcium cyanamide. Stubble has a distinct effect on denitrification and nitrogen assimi- lation but not on the other changes. The effect of bringing the lower layers of soil to the surfate was seen chiefly in diminished nit4rification; the effect was less in the case of the decomposition of bone-meal and urea and no effect was observed as regards nitrogen ztssimilation and the decomposition of calcium cyanamide.The dryness in July was particularly iiijurious in connection with nitrification nitrogen assimilation and the decomposition of calcium cyanamide but had practically no effect on denitrification and the decomposition of bone-meal and urea. For the uninterrupted con- tinuance of the various changes in the soil 60-80 per cent. of the water-holding capacity of the soil is required ; for some changes 50 per cent is too little. N. 13. 5. M. Transformations of Sodium Nitrate in the Soil of Sugar- beet Fields. JULIUS STOKLASA (Zeit. Zuckerind. Bohm. 1905 30 l-S).-It was formerly thought that when used as a fertiliser sodium nitrate is only absorbed in small qiiantity by the surface soil and that the amount of this salt not assimilated by the roots of plants is washed through into the sub-soil.The author finds that this view is erroneous and that the sodium nitrate is assiniilated also by algz and bacteria especially Clostriclium gelatinosum which are always present in soil in which sugar-beets have been cultivated and which convert the nitrate into ammonia. The sub-soil never contains more than about half the amount of nitrogen present in the surface- soil in which the active bacteria are a t work. The nitrogen of the nitrate is converted into organic and ammonia-nitrogen the latter amounting t o from 5 to 10 per cent of the total nitrogen of the nitrate. T. H. P.

Basic slag-ammonia is of no practical importance owing to losses when kept. I n four weeks there was a loss of 20.9 per cent. of the total nitrogen. The immediate effect of basic slag or I)one-meal and kainite is increased by mixing the manures before applying them to the soil. The after effect is somewhat diminished but the total effect over two years is greater when the manures are mixed than when applied separately. N. H. J. M. Retrogression of Soluble Phosphates in Mixed Manuras. GEORGE GRAY (Trans. Austral. dssoc. Sci. 1904 157-161).-1n a mixture of superphosphate and bone-dust retrogression is slight and the citrate-soluble plrQsphoric acid increases at the expense of the insoluble phosphate. Bone-dust is the beet form of tricalcium phos- phate for mixing with superphosphate. Coral Queen guano reduced 7 per cent. of the soluble phosphoric acid in eighteen days. With Chesterfield guano which contains much calcium carbonat,e (37.9 per cent.) retrogression was considerable tricalcium phosphate being formed. Addition of basic slag resulted in 50 per cent. of the phos- phoric acid being rendered insoluble in three hours owing pzrtly to the lime but more particularly to the oxides of iron. With slaked lime retrogression was very rapid and with ground limestone considerable. Kainite had only a slight effect due chiefly to the magnesium salts. N. H. J. M,

849 Organic Chemistry. Mineral Oil from the Torbanite of New South Wales. JAMES M. PETRIE (J. Xoc. Chem. Ind. 1905 24 996-1002).-The relationship of torbanite to other bituminous minerals is discussed and its microscopic structure and composition recorded. It contains a very small quantity of natural oil (up to 0.3 per cent.) which can be extracted by prolonged agitation of the pulverised slide with ether. The natural oil resembles vaseline in consistency and has a reddish- brown colour with a dark green fluorescence. It solidifies a t 30" and begins to boil at 160O; i t has sp. gr. 0.9516 a t 2Oo/4O and n 1.5335 at 20". The crude oil resulting from the destructive distillation of torbanite as well as the four fractions (naphtha solar oil heavy oil and residue) obtained by treating the crude oil with sulphuric acid and then with sodium hydroxide and distilling were subjected to fractional distillation.The volumes specific gravities refractive indices bromine absorption and substitution values and in some cases the vapour densities of the various fractions are recorded. The olefines form about 70 per cent. of the lightest distillate but the pro- portion decreases as the boiling point rises until at 280" the distillate consists almost entirely of parafhns. The naphtha which forms 9 per cent. of the crude oil consists of approximately equal parts of paraffins and olefines with boiling points ranging from 30" to 200" and sp. gr. 0*660-0*800 the paraffins in this fraction ranging from pentane to undecane. The solar oil forms 54 per cent. of the crude oil boils from 2O0-2i'O0 and the sp.gr. ranges from 0.800-0.870. It contains 50 per cent. of paraffins in the lightest portion the proportion increasing to 80 per cent. in the fraction dis- tilling at 270". The paraffins included range from dodecane to penta- decane. The heavy oil constitutes 17 per cent. of the crude oil. Tho lightest portion boiling between 270' and 3OOo contains the last traces of the olefines together with penta- and hexa-decanes. The paraffins C17H to C30H62 represent the oil boiling above 300". Chrysene appears at the end of the distillation. Minute quantities of benzene and its homologues were detected i n the crude oil together with a notable quantity of phenols and a trace of thiophen and nearly all the distillates deposited pyrrole-red on standing.The behaviour towards mixtures of sulphuric and nitric acid and the high sp. gr. of the distillates point to the presence of naphthenes in the oil. H. A l . D. Incomplete Combustion of Gases. Cause of the Lumin- osity of Flame. WILHELM MISTELI (Chem. Centv. 1905 ii 1075 ; from J. Gadel 48 802-804. Compara Tanatar Abstr. 1901 ii 13 228).-By the explosion of mixtures of ethylene and electrolytic It consists chiefly of saturated hydrocarbons. The crude oil is a mixture chiefly of paraffins and olefines. VOL.

Similar results are ob- tained broadly speaking by the incomplete combustion of propylene acetylene and methane. The explosion of mixtures of propylene and electrolytic gas occurs when two volumes of oxygen are present marsh gas and traces of acetylene being formed. The presence of 18 per cent. of propylene completely inhibits combustion. The phenomena appear in this case to be affected by the shape of the explosion vessel. The explosion of acetylene and electrolytic gas is not dependent on the proportions of the gases and traces of methane are formed.Acetylene propylene and ethylene are decomposed by the action of the electric spark ; methane is also decomposed but with much greater difliculty. The more readily the gas is itself decomposed the less is the proportion of electrolytic gas required for explosion. Mixtures containing methane behave like thoso containing propylene and do not explode when 0.5 1.5 or 2 volumes of oxygen are present ; com- bustion is prevented by the presence of 32 per cent. of the hydro- carbon. I n mixtures containing ethylene and acetylene which are just ex- plosive the whole of the hydrogen is in the free state and in the case of the other hydrocarbons almost all the hydrogen is free. The oxygen does not react with the hydrocarbons as such but combines only with the products of their decomposition.The effect of the hydro- carbons on the inflammability of electrolytic gas depends therefore on their decomposition the carbon then combining with the oxygen to form carbon monoxide. Hydrogen cannot be accixrately estimated in mixtures of hydrogen and methane or i t s homologues by explosion since small quantities of the former escape combust'ion but the palladium methods of Winkler Runte and Hempel give accurate results. The hydrogen in mixtures containing hydrocarbons can only be estimated by conibuation when but one saturated hydrocarbon of known composition is present. Traces of acetylene are formed by the explosion. E. W. W. Preparation of Halogen Alkyls. RUDOLF F.

A. D. 3 P 2852 ABSTRACTS OF CHEMICAL PAPERS. New Method of Preparing Esters. WILLIAM W. TAYLOR (Proc. Roy. ,570~. Edin. 1905 25 831-834).-The yields obtained in the preparation of esters are frequently unsatisfactory i n consequence of the hydrolysing action of the water formed.I n the method described for the preparation of ethyl esters the water produced is removed by addition of benzene and distillation of the ternary mixture ethyl alcohol benzene and water (compare Young Trans. 1902 81 707). I n the actual working of the process the dry acid is mixed with an excess of ethyl alcohol and after addition of 3 C.C. of alcoholic hydrogen chloride the solution is boiled for 20-30 minutes in a flask provided with a very efficient fractionating column and a tap funnel. A quantity of benzene sufficient to remove one-quarter of the water produced in the reaction is then run in together with a little ethyl alcohol and the ternary mixture distilled off.As soon as all the benzene has come over distillation stops. This process is repeated three times. The residue is then free from water and is transferred to a fractionating flask and distilled under reduced pressure. The method has given good results in the preparation of ethyl tartrate oxalate succinate and benzoate. H. M. D. Metallic Formates and Acetates.

D. H. J. Esteriflcation Experiments. ALEX. D. BOGOJAWLENSKY and J. NARBUTT (Bey. 1905 38 3344-3353).-The effect of the intro- duction of various metallic salts on the esterification of organic acids by ethyl alcohol has been studied. The salts employed mere ferrous zinc cobalt cupric sodium manganous and nickel sulphates also potassium pyrosulphate and chabazite. Experiments made with succinic acid using the acid sulphate and alcohol in the proportions 1 1.25 4 and boiling for about four hours show that as regards their efficiency the salts may be armnged in the order ferrous nickel cupric manganous cobalt and zinc sulphates.Sodium sulphate has no accelerating action. Copper sul- phate accelerates the esterification of other aliphatic acids such as acetic In-butyric isovaleric and citric acids ; the acceleration is further increased by the addition of a little free sulphuric acid. Potassium pyrosulphate gives extremely good results with aromatic acids such as benzoic salicylic o-nitrobenzoic gallic cinnamic and mandelic acids whereas copper sulphate is not advantageous. The sulphates were dehydrated at 100' ; their action may be partly due to their hygro- scopic nature and partly to the small amount of free acid to which they give rise.Copper sulphate is of no use for the esterification of trimethyl- carbinol with acetic acid. Salol cannot be obtained by using potassium pyrosulphate and a- and P-naphthols cannot be esterified by this reagent. J. J. 8. Tetra-amminechromium Salts. PAUL PFEIFFER (Bey. 1905,38 9352-3601.

The additive compound of ethyl chloroacetate and ethyl sodiopropylmalonate is formed in ethereal benzene solution and on evaporation is obtained as a red viscid oil. These derivatives of methyl- and propyl-malonic acids have properties resembling those of the corresponding ethyl compound. The action of ethyl chloroacetate on ethyl sodioacetoacetate in warm ethereal solution leads to the formation of Fodium chloride but in benzene solution to the formation of a slightly alkaline orange solu- tion which deposits sodium chloride on addition of traces of water but only slowly on treatment with methyl or ethyl alcohol ether ethyl acetate or chloroform.The additive compound is obtained on distillation of the benzene and beating the residue at l l O o under 12 mm. pressure as a viscid orange slightly milky liquid which dissolves unchanged in benzene but is less stable towards methyl or ethyl alcohol ether ethyl acetate or chloroform than are the corre- sponding malonate derivatives. The additive compound of ethyl chloroacetate and ethyl Fodioethyl- acetoacetate is formed in ethereal solution and is obtained on evapora- tion as a red viscid liquid ; it is decomposed immediately by water but dissolves in methyl alcohol or ethyl acetate to form a clear solution which decomposes only gradually.Comparative experiments show that the action of alkyl iodides on sodio-derivatives of ethyl acetoacetate or malonate as expressed by the changes of temperature takes place more rapidly than on sodium alkoxides.

Formaldehyde in Aqueous Solution.FRIEURICH AUERBACH and HERMANN BARSCHALL (Chem. Centr. 1905 ii 1081-1083 ; from Arb. Kuis. Ges.-A. 22 584-629).-Aqueous solutions of formaldehyde are prepared by subliming triosymethylene in a stream of nitrogen and absorbing the va,pour in water. Lumibre and Seyewetz' method (Abstr. 1903 i I5Oj may be used for the analysis of the solutions if the correction for the hydrolysis of tho sulphate solution is properly applied. Romijn's method is better adapted for small quantities of dilute solutions if the following J. J. S.860 ABSTRACTS OF CHEMICAL PAPERS. conditions are observed. Pure alkali hydroxide preferably prepared from the meta1,should be used the solution of iodine and alkali should not be mixed before adding the aldehyde the addition of too much acid is to be avoided and the liquid should be continuously shaken during the titration with sodium thiosulphate.If an insufficient quantity of iodine is used in the first instance this cannot be remedied by adding more after the titration. The oxidation of the aldehyde appears to be entirely effected by the hypoiodite formed by theaction of the iodine on the alkali hydroxide. The agitation of the solution during the titration is necessary to avoid the action of the thiosulphate on the acid. The sp. gr. of pure aqueous solutions of formaldehyde at 18' is given in the original paper and the relationship of the average molecular weight of the aldehyde in its aqueous solution to the concentration has been determined. By means of the application of the law of mass action to the data obtained it is shown that an equilibrium is established between the molecules of formaldehyde CH,O and those of the polymeride (CH,O),.A better agree- ment between the observed and calculated values is obtained how- ever when i t is assumed that both forms are hydrated methylene glycol being formed from the aldehyde CH,O. This assumption does not preclude the possibility of the occurrence of very small quantities of higher polymerides in very concentrated solutions and in fact the deviations shown by solutions of 37-38 volumes per cent. point to this explanation. The reaction between the two forms in aqueous solutions is reversible and the equilibrium is attained in a short time when either gaseous formaldehyde or the polymeride is dissolved. As the temperature is raised the latter tends to decompose into the simpler form this change being accompanied by absorption of heat.Foelsing's (Zed. ofentl. Chem. 1904 322) statements in reference to the effect of the preservative '' sterilisol" and the difference shown by solutions prepared in a vacuum do not correspond with the facts the composition of solutions which have been allowed to remain for a few hours being independent of the method of preparation. When solutions of formaldehyde are distilled the distillate is always weaker and the residue stronger. The boiling point of aqueous solutions decreases with the concentration and all solutions contain- ing more than 30 vols. per cent. boil at practically the same tem- perature hence on distillation a distillate of a higher boiling point is obtained (compare Konowaloff Abstr.1881 1093). The relation- ships of the composition of the vapour from boiling formaldehyde solutions to the quantity of aldehyde in the solution and the partial pressure of the aldehyde in solutions at 100" have been determined. The partial pressure in solutions at 1 8 O has been estimated by means of a current of air. Since these methods gave very low values it would appear that only a very small portion of the aldehyde is contained in the solution in the form of the simple molecule CH,O. From the partial pressures the quantities of aldehyde which would be contained in a given volume of saturated vapour at 18' have been calculated. I n the case of the strongest solution which contained 33.8 vols. per cent.it was found that the quantity was only 0.66 gram,ORGANIC CHEMISTRY. 861 and for the commercial 40 per cent. solution in methyl alcohol less than 1 gram. I n practice however complete saturation of the vapour is never attained. E. w. w. Action of Ammonia and of Amines on Chloral. MITSURU KUHARA and YOSHINORI KISHI (Mem. CoZZ. 8ci. Eng. K3iito 1904-1905 1 114-124).-The action of ammonia on chloral in the free state and in chloroform solution a t various temperatures has been examined. The observations indicate that chloral ammonia is the first product but that this is decomposed either (1) by rise of temperature or (2) by the action of an excess of ammonia into chloroform and formamide according to the equations (1) CCl,*CH(OH)*NH = CHCI + CHO*NH ; CCl,*CH(OH)*NH + NH = CHC1 + CH(N H2);OH = CHCI + NH + CHO-NH,.The aliphatic amines are supposed to react similarly towards chloral and the entirely different behaviour of the aromatic amines which yield trichloroethylidene derivatives is ascribed to their much weaker basic properties. If aromatic amines are treated with chloral ammonia instead of with chloral formyl derivatives of the amines are however obtained. I n this reaction the chloral ammonia first decomposes into chloroform and formamide the latter then reacting with the amine. A number of formyl derivatives of aromatic amines were prepared according t o this met hod. H. M. D. (2) Condensation of isoPropylacetaldehyde [isovaleraldehyde] with Acetaldehyde. BRUNO EERENFREUND (Monatsh. 1905 26 1003 -1010).-The condensation of isovsleraldehyde (Rainer this vol.i 16) with acetaldehyde in presence of potassium carbonate has been re-investigated as the isovaleraldehyde used by Wogrinz (Abstr 1901 i 254; 1903 i 604) contained a t least a-methyl- butaldehyde in addition. The aldol CH,Prp*CH(OH)*CH,*COH or OH*CHMe*CHPrp*COH is now found to boil at S 5 O under 15 mm. pressure and on oxidation with potassinin permanganate to form in addition to isovaleric acid a hydroxy-acid C7H,,0,. The unsaturated aldehyde CH,Prp*CH:CH*COH o r CHMe:CPrp*COH is obtained best by heating the aldol with sodium acetate; on oxidation it yields isovaleric acid oxalic acid and only a small amount of acetic acid. Reduction of the unsaturated aldehyde with iron filings and acetic acid leads to the formation of a product which is probably identical with Grimshaw's isohexylcarbinol (this Journal 1873 313) and on oxidation with potassium permanganate yields isoheptoic acid boiling at 2 1 1-2 14".I n other respects the properties of the substances obtained agree with those described by Wogrinz (Zoc. cit.). Action of Lead and Bismuth Salts on the Rotatory Power of Sugars Polyhydric Alcohols and Hydroxy-acids. 11. HEnMANN GROSSYANN (Zed. Ver deut. Zucker-lnd. 1905 596 941-976. Compare this vol. i 415).-The results of the author's G. Y.862 ABSTRACTS OF CHEMICAL PAPERS. investigations on a large number of sugars polyhydric alcohols and hydroxy-acids show that most of these compounds readily react with alkaline solutions of lead salts the hydrogen atoms of the hydroxyl groups being replaced by lead oxido.Owing to the change produced in the optically active molecule by the influence of the heavy lead atom the formation of these complexes is often accompanied by a change in the sense of the rotation The alkali necessary for the solution of the insoluble lead compounds a t first produced frequently influences the rotation very greatly especially with tartaric and quinic acids. The lead-alkali compounds of the hexoses are in general possessed of but little stability the free alkali very soon producing intra-molecular changes. A solution of bismuth nitrate in glycerol and water exerts on addition of an alkali hydroxide an influence on the rotation of tartaric acid with which toget her with the dextrorotatory complexes present in alkaline solution strongly lzvorotatory complexes only stable in presence of hydrogen ions are formed. Saccharic acid is converted by alkaline bismuth solution into a strongly dextrorotatory substance.The dextrorotation of mannitol produced by bismuth nitrate is greater in aqueous solution than when glycerol is added. Of the sugars only I~evulose and invert sugar are appreciably influenced in rotation by alkaline bismuth nitrate solution. The rotations of arabinose galactose dextrose sucrose lactose maltose and rnffinose are diminished by alkaline bismuth nitrate solutions but the change is here ascribed to the excess of alkali present since increase of the amount of bismuth salt is not accompanied by a corresponding change in the rotation. The same probably holds in the case of quinic acid.T. El. P. Acetosulphate of Cellulose. 11. CHARLES F. CEOSS EDWARD J. BEVAN and JOHN F. BRIGGS (Ber. 1905 38 3531-3538.

LEO TSCHUGAEFF (Bey. 1905 38 2899-2914. Compare Tschugaeff Abstr. 1904 i 478 ; Ley this vol. ii 524).-The compounds of the type (Su),Cu,2a where Su represents the succinimide group C6H,(CO),N and a the particular amine used are prepared by four general methods.(1) The reaction formerly employed where cupric chloride (1 mol.) and succinimide (2 mols.) are acted on by the amine in alcoholic solution is of general applicability but has the objection that half of the amine used is lost since the reaction proceeds in the sense 2SuH + CuCI + 4a = C ~ ( S u ) ~ 2 a + 2a,HCI. (2) When' copper turnings are brought into contact with an alcoholic solut.ion of ammonia or of a primary amine in presence of oxygen the copper is oxidised only slowly ; when however succinimide is added the solution quickly becomes dark blue and a red compound separates a t once. The change is represented by the equation 4SuH + 4a + 2Cu + 0 = 2(S~)~Cu,2s+2H,0. (3) A suitable method where the amount of amine available is small is that of warming coppersuccinimide hexa- hydrate with the amine in alcoholic solution.(4) A solution of cuprammine hydroxide in water or in aqueous alcohol is first prepared and then succinimide and an excess of alcohol added the action pro- ceeding according to the equation Cu(Za)(OH) + 2SuH = (Su),Cu,2a + 2H,O.

When the chloride C,Hg,C16 is mixed with potassium polysulphide solution and the solution repeatedly renewed so long as mercuric chloride is formed the compound C,Hg,CI,SH is obtained in the form of brilliant yellow needles.The same product is obtained when the mixture is heated at 100" and is purified by mashing with potass- ium sulphide solution water alcohol carbon disulphide and ether. When the yellow crystals are boiled with hydrochloric acid an intense alliaceous odour is noticed and a white crystalline powder is formed which turns yellow on the addition of hot sodium hydroxide solution.

Lincei 1905 [v] 14 ii 127-132).-The water which is eliminated in the reaction between a nitric ester and hydroxylamine is formed from an oxygen atom of the nitro-group and the hydrogen of the amino-residue. This is shown by the fact that the reaction takes place even in absence of the hydroxyl of the hydroxylamine.Thus the addition of sodium to an absolute ethereal solution of molecular proportions of aniline and acetyl nitrate leads to the formation of the sodium salt of phenylnitroamic acid NPhXO-OH which represents the tautomeric form of phenylnitro- amine NHPhoNO,. The latter is isomeric with nitrosophenylhydroxyl- amine to which may be ascribed the two forms OH*NPh*NO Ph*NO:NOH. Hence although nitrosophenylhydroxylamine can be obtained by the action (1) of hydroxylamine on nitrobenzene (2) of hyponitrous acid on nitrosobenzene or (3) of nitrous acid on phenylhydroxylamine it is impossible to prepare it by the interaction of nitric acid and aniline.

Palladium. ALEXANDER GUTBIER [with A. KRELL and R. L. JANsSEN] (Zeit.anorg. Chem. 1905 47 23-41).-1n former papers (this vol. ii 584) the preparation of double salts and palladosammine derivatives by interaction of palladous chloride and bromide with the hydrochlorides and hydrobromides of aniline and 0- and p-toluidine has been described. Corresponding compounds of xylidine p-anisidine and a- and P-naphthylamine have now been prepared by the methods previously given. Whereas the double salts can be readily crystallised from dilute hydrochloric and hydrobromic acids respectively the palladosammine derivatives are extremely insoluble and so far no satisfactory solvent has been found for the naphthylamine and benzidine compounds. The xylidine and p-anisidine derivatives can be crystallised from a large excess of alcohol. The phenylenediamines react differently from the other bases since salts of the meta- and para-compounds yield double salts with the palladous salts under all conditions whereas the ortho-compounds yield only platosammine derivatives.The latter are so stable that they can be recrystallised from the corresponding dilute halogen acids. All the palladosamrnine compaunds here described are acted on by warm concentrated ammonia the base being set free and a pallado- diammine chloride or bromide [Pd(NH,),CI,] formed. On heating t h e base is driven off and finally the diammine loses two molecules of ammonia palladosammine chloride or bromide remaining in solution.

The solutions show a fine bluish-violet fluorescence (compare Abstr. 1904 i 314). On reduction by means of sodium amalgam in alcohol tbis hydrocarbon is converted into the corresponding dihydride which crystallises from acetic acid in colour- less silky needles melts a t 179q and is soluble in most organic solvents.On exposure to air the dihydride slowly acquires a green- ish tint due to superficial oxidation to the parent hydrocarbon and like the latter on oxidation with potassium dichromate yields the original 9 10-dihydroxy-9 10-diphenyl-2-metbyldihydroanthracene. The latter readily condenses with various aromatic compounds to vield comdex derivatives thus with dimethylaniline it furnishes (cis and hans) both bk'ing colourless crystalline powders one melts at 312" and is slightly soluble in most organic solvents the other melts a t about 147" and is readily soluble. Both forms yield crystal- line picrates and platinichlorides and salts which are dissociated by water. These substances give no coloration when dissolved in sulphuric acid.When the condensation is carried out at lo@' only one of the hydroxyl groups is replaced by t,he dimethylaniline residue. The product appears to be a mixture of at least two isomerides and on adding hydrochloric acid to its solution in alcohol two substances are obtained one melting a t 155' and the other a t 125".

RIETZ (Ber. 1905 38 3302-3307).-+-Phenols do not con- dense so readily with phenols as with tertiary aromatic amines (Abstr. 1904 i 995). The mixture has to be heated for several hours at 100-150° in the absence of a solvent. The products are diphenylmethane derivatives and as a rule pure products can only be isolated when the phenol has only one ortho-hydrogen or the para- hydrogen atom unsubstituted.I n certain cases 2 mols. of +-phenol react yielding bis-derivatives which are more sparingly soluble. 3 5-Dibromo-khydroxybenzyl bromide (Abstr. 1903 i 621) and o-cresol yield a product melting at 99-105' and consisting probably of a mixture of 0- and p-dibromohydroxybenzylcresols.

When this compound is left in contact with methyl alcohol a reaction takes place very slowly with formation of the additive compound C,,O,Br,,ZMeOH which crystallises from alcohol in white rhombic plates melts and decom- poses a t 220-221° and is soluble in benzene or acetone soluble to the extent of 4.3 per cent.in boiling alcohol and insoluble in water. This compound is best obtained by adding solution of sodium methoxide to the hexabromo-o-quinocatechol ether suspended in methyl alcohol and treating the product with hydrochloric or sulphuric acid ; the sodium derivative C,,O,Br,,MeOH,MeONa is unstable and on decomposition yields a substance which crystallises in red needles decomposes at about 280° and is soluble in water or alcohol. By the action of methyl alcohol and bromine on t h o methyl alcohol additive compound a substance is formed which melts a t about 150'. When phenylhydrazine is added slowly to a mixture of hexabromo-o-quino- catechol ether and nitrobenzene hexabromodihydroxycatechol ether is produced; this reaction furnishes a convenient method for the preparation of this substance.E.

Dinitrofluorescein (Hewitt and Perkin Trans. 1900 77 1324) dissolves in alkali with formation of a deep blue solution which shows no fluorescence. An attempt was made to prepare tetranitrofluorescein (Baeyer this Journal 1877 i 200,and Hewitt and Perkin Zoc.cit.) by theaction of fuming nitric acid on a solution of fluorescein in sulphuric acid. TheORGANIC CHEMISTRY. 897 product crystallised from acetone as a white powder with a distinct yellowish-green fluorescence and on analysis gave results agreeing with those required for a pentanitro- rather than a tetranitro-com- pound.

A. W.ORGANIC CHEMISTRY. 913 Aloes. ALEXANDER TSCHIRCH and 0. HOFFBAUER (Arch. Pharm. 1905 243 399-420).-From Zanzibar aloes an cdoin could not be obtained satisfactorily by means of lime or of chloroform and methyl alcohol. It was found best to allow the powdered drug to remain for several days with an equal weight of alcohol the mixture being shaken occasionally and then to recrystallise the insoluble portion (zan- aloin) from dilute alcohol isoAloin is not present. From Jaferabad Barbadoes and Curaqoa aloes the aloins (jafaloin barbaloin and curaloin) could be obtained by extracting with methyl alcohol and freeing the extract from resin by precipitation with chloroform.Barb- aloin and curaloin are identical with melting point 147' and composi- tion C1,Hl,O7. Capaloin from Aloe Zucada and the aloin OF the Uganda aloe are also identical with melting point 147O but composition Cl6,H1,P7 ; zanaloin also has this composition but melts a t 2 12'. Jafaloin melting a t 152' and containing C 605 H 5.5 per cent. and nataloin are distinct individuals. The aloes from the Barbadoes con- tained but little isoaloin and those from Jaferabad contained none whilst those from Curaqoa contained a considerable quantity. Aloin-reds were isolated from Natal and Curaqoa aloes in very small amount in the latter case. The former has the composition C16H16089 of an oxidation product of nataloin; it does not yield chrysamic acid when heated with concentrated nitric acid whereas curaloin-red does.The solubilities and absorption spectra of several aloin-reds are described. From Curaqoa aloes an anthrccglucoside was isolated which by boiling with 1 per cent. sulphuric acid was hydrolysed to emodin and a sugar of which the phenylosazone melted at 183' (compare Leger Abstr. 1904 i 907). When hydrolysed with boiling 10 per cent sulphuric acid the resin of Zanzibar aloes yields p-coumaric acid and that of Curaqoa aloes cinnamic acid whilst the corresponding acid product from Jaferabad aloes could not be isolated ; in all cases a resinotannol was obtained also. All these resinotannols yield picric and oxalic acids when heated with nitric acid of sp. gr. 1.27. Barb- and cur-aloresinotannols have the composition C22H2606 ; zanaloresinotannol is C,,H,?O isomeric with cap- and nat-aloresinotannol ; whilst jafaloresinotannol is C20H1806 isomeric with feroaloresinotannol.Accompanying jafalo- resinotannol is a substance which is soluble in water and yields a little chrysamic acid when oxidised with nitric acid.

Compare Abstr. 1904 i 921)- The aliphatic amines differ from the aromatic amines in their behaviour towards dinitrophenylpyridinium chloride. Amorphous substances which yield red hydrochlorides are at first formed dinitroaniline not being eliminated. Prolonged treatment however causes the forma- tion of dinitroaniline and quaternary pyridinium salts. The red salts are related to the substances produced by the action of alkalis and phenylhydrazine on the pyridinium compound. These red salts are represented by the formula LC,H,(NO,),*C,NH,I*NHAl~HCl; they are decomposed by aniline with the formation of the dianilide (compare Abstr. 1904 i 923). When heated with hydrochloric acid dinitro- aniline is formed and a pyridinium salt C,NH,AlkCl in the case of the compounds of primary amines. The products obtained from secondary amines are decomposed to R much greater extent by hydro- chloric acid.Primary aliphatic amines do not yield compounds coi-re- sponding with the dianilides.

Compare Hantzsch Abstr. 1900 i 365).-A mixture of a solution of crystal-violst and hydrochloric acid when kept at a constant temperature shows a diminution of electrical conductivity as the time iticreases until a limiting minimum is reached. This phenomenon indicates a diminution of hydrogen ions due to the formation of a polyacid salt and ultimately a state of equilibrium between the mono-salt hydrochloric acid and the polyacid salt (called by the authors trisalt-p) is attained. This trisalt-p does not appear to be analogous t o Hantzsch’s trisalt C(CGH,NMe2),Br( HBrJ2 which is termed trisalt-a.The constant K for (mono-salt)(HC1)2/(trisalt-p) is 1-12 x Hantzsch’s trisalt-a on solution in water gives immediately a constant conductivity which is practically identical with the additive value calculated for 1 equivalent of mono-salt + 2 of hydrobromic acid. The conversion into mono-salt is thus practically instantaneous and the constant K for this change can thus not be calculated The constants for the incomplete changes (1) mono-salt + 2HCl -+ trisalt-p Kl (2) trisalt-p -+ mono-salt + 2HCl K2 have been found to be Kl = 5.2 and K2= 5.8.10-3.

RICHARD HERMANN (Monatsh. 1905 26,102 l-l037).-Nitroanilines do not interact with dicyanodiamide. p-Nitrophenyldiguanide is obtained in the form of its sulphate (CsHi,02N,),,H,S0 by treating phenyldiguanide hydrochloride with nitric acid of sp. gr. 151 and concentrated sulphuric acid at 30-40'. The sulphate crystallises in matted white hair-like needles and melts at about 254'. The free base C,~H,,O,N,.H,O separates from alcohol in yellow doubly refractive prismatic leaflets loses H20 a t 105' and melts at lS2O. The picvate forms a yellow amorphous pre- cipitate; the silver nitrate derivative is obtained as a yellow floc- culent precipitate.When heated with concentrated aqueous potassium hydroxide at 1 25-130° the baee yields p-nitroaniline. op-~initrophnyldiguccnide C,H,O,N formed by the action of nitric acid of sp. gr. 1.5 1 and concentrated sulphuric acid on p-nitro- phenyldiguanide at 75-80' is obtained in the form of its sulphate (C~H90,N7),,H,S0 which crystallises in yellow needles and melts at 234'. The free base crystallises in doubly refractive orange-yellow needles melts at 193' has a slight basic reaction towards litmus and yields a yellow amorphous pi*ecipitate with silver nitrate. The oxalate crystallises in nodular aggregates of broad needles ; the picrate forms a yellow precipitate. When heated with dilute sulphuric acid at 160--170' the base is hydrolysed with formation of 2 4-dinitro- aniline which melts at 181-182' (m.p. 175O; Rudnew this Journal 1871 24 712). 2 4 6- Trinitrophenyldiguanide sulphate (C,H,O,N,),,H,SO formed by the action of nitric acid of sp. gr. 1.51 and concentrdted sulphuric acid on op-dinitrophenyldiguanide at 105-1 lo" crystallises in misro- scopic broad yellow leaflets melts a t 270' and is hydrolytically dis- sociated when boiled with water or alcohol.

When heated with dilute sulphuric acid G. Y. A New Method of Formation of Diazo-compounds and a General Method for Determining the Constitution of Azo- dyes. OTTO SCHMIDT (Bey. 1905 38 3201-3210).-The action of filming nitric acid cooled by ice on azo-dyes containing an auxo- chromic amino- or hydroxyl group in the para-position to the azo- group leads to the formation of the diazo-compound from which the dye is prepared the other component appearing as a nitro-derivative ; if the auxochromic group is in the ortho-position the decomposition takes place completely only with P-naphthol dyes but partially with p-cresol dyes whilbt the reaction takes place only to a small extent or does not take place with azo-dyes containing the auxochromic group i n the meta-position.Other azo-cotiipounds such as azobenzene are not decomposed by fuming nitric acid. Azoxy-compounds which contain a p-amino-group such as pp'-tetra- ethyldiaminoazoxybeazene are decomposed by fuming nitric acid with formation of diazo-compounds.These azoxy-compounds as also azo- dyes containing a n auxochromic group in the para-position are decom- posed in the same manner by chromic or permanganic acids i n glacial acetic acid solution. Helianthiri (1 6.4 grams) yields 8.1 grams of op-dinitrodimethyl- aniline 1 *2 grams of tetranitrodimethylaniline and diazobenzene- sulphonic acid which when coupled with P-naphthol forms 19.2 grams of the dye OH*C H,*N,*C,H,*SO,Na which crystallises iu glistening bronze leaflets. ~etra?zitrodimet7LyZaniline C7H,0,N crys- tallises from alcohol is yellow and melts a t 128-129O. p - i V i t r o - p ' - m e l h o ~ ~ ~ ~ o ~ e n ~ e ~ e C,,H 1103N3 is formed by the action of methyl iodide and sodium methoxide on p-nitro-p'-hydr.oxylizobenzeue in boiling methyl-alcoholic solution.It crystallises in yellowish-red flat needles melts a t 157.5-158" and when 5 grams are treated with cooled fuming nitric acid yields 2.5 grams of op-dinitroanisole melting at 88" and the diazo-compound which with /3-naphthol forms 4.41 grams of p-nitrobenzeneazo-P-naphthol melting a t 25 1 -2-252-5". When treated with fuming nitric acid 4 grams of orange 11 yield 1.7 grams of a nitro-derivative of P-naphthol and diazotised sulphanilic acid which when coupled with phenol forms 2 grams of the azo-dye. I n the same manner 2 grams of P-nuphtholazobenzene-o-carboxylic acid yield 1.4 grams of a nitro-P-naphthol and 1.8 grams of the dye is recovered by coupling the diazo-compound formed with &naphthol.Satisfactory yields of diazo-compounds are obtained from p-ethoxy- p'-hydroxyazobenzene p-hydroxyazobenzenesulphonic acid benzene- azo-P-naphthol and p-ethoxybenzeneazo-P-naphthol ; but m-hydroxyazo- benzene the product obtained on coupling diazotised anthranilic acid with p-cresol azobenzene p-azotoluene and t etramethyl-mni-diamino- azobenzene do not yield or yield only small amounts of diazo-com- pounds.

MEISTER LUCIUS and BRUNING (D.R.-P. 160281).-Hypochlorous acid and its salts react with chromotropic acid (1 8-dihydroxy- naphthalene-3 6-disulphonic acid) yielding a cldorochromotropic acid in which the chlorine atom probably occupies the ortho-position to one of the hydroxyl groups.This acid does not readily combine with diazotised amines but combines with diazotised nitroamines and the resulting compounds may be reduced with sodium sulphide a t 50-60° to blue aminoazo-dyes. Thus p-nitroaniline chloro-p-nitroaniline or 2 5-nitroaminoquinol dirnethyl ether may be employed. C. H. D. A New Method of Formation of Osotetrazones.

G. Y. The Bence-Jones Proteid. EMIL ABDERHALDEN and OTTO ROSTOCKI (Zeit. physiol. Chem. 1905 40 125-135).-The proteid was obtained from the urine in a case of bone sarcoma. On heating it is pre- cipitated a t 50-60" ; this precipitate dissolves on boiling and reappears on cooling; other properties which are described show it to be similar to the proteid described in previous cases When a solution of it is injected into rabbits i t does not pass into the urine and a precipitin is formed in the rabbits' blood which however acts not only on the Bence-Jones proteid but also on the proteids of normal serum.On hydrolysis 100 grams yield-glycine 1.7 ; alanine 4.5 ; leucine 10.6 ; proline 1.9 ; phenylalanine 1.5 ; glutamic acid 6.0; aspartic acid 4.5 ; and tyrosine 1.7 grams. Lysine arginine and histidine were also detected. W. D. H. The Composition of the Proteid of Aspergillus Niger* EMIL ABDERHALDEN and PETER RONA (Zeit. physiol. Chem. 1905 46 179-186).-AspergiZZu~ niger was cultivated on various nitrogenous media ; its proteid matter yields on hydrolysis glycine alanine leucine glutamic and aspartic acids. Aromatic products such as tyrosine and phenylalanine were not discovered.The experiments point to the independence of the proteid and the medium on which the mould is grown but this cannot be asserted with confidence until quantitative experiments are made. W. D. H. Influence of Acids and Alkalis on the Swelling of Gelatin. WOLFGANG OSTWALD (PJliiger's Archiv 1905 108 563-589).-The swelling of gelatin in acids and alkalis depends in a complex manner on the concentration the rate increasing with concentration to a maximum at N/40 for hydrochloric acid and N/36 for potassium hydroxide. With higher concen trations the rate again diminishes the fall being at first rapid then very gradual. Similar results are obtained with other acids and alkalis. The type of curve obtained shows a general parallelism with those representing other properties.The author points out that any theory which attempts to explain the physico-chemical properties of colloids must account for these peculiar curve relations. The absolute value of the swelling is much larger thas in pure water; the absorption of liquid being with acid 3-4 times and with the optimum alkali 3 tinies as much. J. J. S.

The precipitate obtained from a peptone of unknown genesis con- tained C = 48.78 €€ = 7-39 N = 16.63 S = 1.29 and ash = 0.023 per cent. whilst that from a specimen of Witte’s peptone contained C = 49.55 50.31 H = 8.63 7.55 N = 13.75 S =- 1.1 1 and ash = 0.1 65 per cent. The filtrate from the flocculent precipitate becomes opaque on warming and this precipitation is greatly increased on adding acetic acid whereas a solution of peptone slightly acidified with acetic acid remains clear when heated by itself or with a further addition of acetic acid or in presence of 1 per cent. of sodium chloride. The filtrate gives positive results with the xanthoprotein Spiegler’s the biuret and Adamkiewicz’s reactions for albumin as also with concentrated nitric and sulphuric acids and with concen- trated sulphuric acid and saccharose ; it blackens alkaline lead solutions on boiling. An acidified solution of peptone gives a yellowish-brown coloration with the xanthoprotein and only a slow precipitation with Spiegler’s reagent. Fractional precipitation experiments according t o Pick’s method (Abstr. 1898 i 288) show that in the formaldehyde-peptone filtrate the albuminoses which are soluble in semi-saturated ammonium sulphate solution have been converted into albumins which are easily salted out and part of which correspond with Fuld and Spiro’s euglobulin (Abstr. 1901 ii 67). Pure peptone is obtained by saturating an aqueous solution of Witte’s peptone with ammonium sulphate concentrating the filtrate and precipitating the ammonium sulphate with alcohol. This when treated with formaldehyde in aqueous solution at the winter terripera- ture remains clear even if saturated immediately with ammonium sulphate 1)ut forms a precipitate if saturated after some days and after t w o months becomes opaque when warmed with 1 per cent. of sodium chloride. If the treatment with formaldehyde is carried out a t the summer temperature condensation takes place immediately with formation of a precipitate which dissolves in dilute sodium hydroxide to form a solution from which acids precipitate a substance with the properties of an alkali albuminate. The filtrate from the condensation precipitate forms a precipitate when half saturated and again when completely saturated with ammonium sulphate. When distilled the alkaline solution of the condensation precipitate yields a distillate which has an odour resembling that of formalde- hyde and precipitates a black powder from warm ammoniacal silver nitiate solution but does not give the formaldehyde reaction with alkaline resorciuol. The residual alkaline liquid does not form a precipitate when acidified. The Condensation precipitate does not yield formaldehyde when heated with acids. G. Y.

J. J. S. Catalase. PHILIP SHAFFER (Amer. J. Physiol. 1905 14 299-31 Z).-The main conclusion drawn from the experiments recorded is that the catalase action of plant and animal extracts liberates oxygen in a molecular condition. It is therefore not an oxidising enzyme but destroys the peroxide in such a way that oxygen is not liberated in an active condition ; the tissues are thus protected from injurious oxidation. W. D. H.

Compare ibid. 1903 104 207).-Heating malt-extract above BOO or shaking it with mercuric oxide and magnesia destroys the catalase which causes the decomposition of hydrogen peroxide but the solution still induces the guaiacum reac- tion particularly if oil of turpentine is present. Hence the authors conclude that contrary to the view held by Neumann-Wender (Enxymologishe Studien I 28-35 Berlin 1904) only one enzyme the oxygen-carrier peroxydase is necessary for inducing the reaction. J. J. S. Precipitins. IVAR BANG (Beity. &em. Physiol.

When the dialysed solution is heated albumin coagulates a t 64' and precipitin is contained in the filtrate. Precipitins obtained by injecting ox-blood-serum into dogs do not always behave in the same manner; some give precipitates with both globulin and serum-albumin others with globulin only. J. J. S.

Tho distillate is received in a flask containing potassium iodate solution and in connection with a second flask con- taining a little potassium iodide solution. The sulphur dioxide decom- poses the iodate according to the equation 2KI0 + 550 + 4H,O = K,SO + 4H,SO + I,. After neutrslising the sulphuric acid by the addition of calcium carbonate the solution is titrated as usual with thiosulphate solution. If any iodine passes over into the second flask the contents must not be mixed with the main distillate until after the calcium carbonate has been added. Sodium thiosulphate solution may be standardised as follows 0.1 gram of potassium iodate and 0.3 gram of potassium iodide are dissolved in 50 C.C.of water 20 C.C. of N/10 sulphuric acid are then added and the liberated iodine titrated with the thiosulphate solution.

J. 1905 34 204-21 7).-The conclusion arrived at in the previous paper (Abstr. 1903 ii l S O ) that it is possible to obtain a precipitate of constant composition and in a fit state for weighing is confirmed. For the exact composition of the ammonium phosphomolybdate the first paper should be consulted. It is essential tliat the phosphate solution should be added to the molybdate solution and not the reverse ; otherwise the composition of the compound will be altered. The precipitation should take place in the cold but if much potassium is present this replaces part of the ammonium in the precipitate; this however may be again re- placed by ammonium on heating the precipitate with ammonium nitrate solution thereby converting it into triammonium phospho- molybdate.According to the conditions of precipitation ammonium phosphomolybdate occludes varying amounts of moly bdic acid and ammonium molybdate. No method of estimating phosphoric acid is accurate unless notice is taken of such admixture.

The burette reading should be divided by 2 so as to indicate the percentage of phosphoric anhydride. The process which is a modification of that recommended by Littmann (Abstr. 1889 ii 330j gives results fully agreeing with those obtained by the gravimetric methods. L. DE K. Estimation of Arsenic as Magnesium Pyroarsenate. JUAN FACES YIRGILI (Ann. C h h . f’hys. 1905 [viii] 6 394-407).-A ~bsunzi? of work already published (compare this vol. ii 652). M. A. W. Detection and Estimation of Arsenic and Antimony in Presence of Organic Matter.F. A. NORTON and A. E. KOCH (J. Amer. Chem. Xoc. 1905 27 1247-1 252).-The process is based on the destruction of the organic matter by heating with sulphuric acid in a Kjeldahl flask. The residue contains the arsenic or antimony in the lower state of oxidation and this may then be a t once titrated with A‘j70 iodine in the usual manner. If the amount of arsenic or antimony is but small a large quantity of the material must first undergo a preliminary treatment in the case of arsenic with nitric and sulphuric acids or in the case of antimony with hydrochloric acid and potassium chlorate. A definite quantity of the solution thus obtained is then boiled in a Kjeldahl flask with sulphuric acid in order to destroy completely the last traces of organic matters.Traces of arsenic are best estimated by the “ mirror ” method. L. DE K. New Method for the Determination of Atmospheric Carbon Dioxide based on the Rate of its Absorption by a Free Surface of a Solution of an Alkali Hydroxide. HOHACE T. BROWN and FERGUSSON ESCOMBE (Yroc. 2209. Xoc. 1905 B 76 11 2-1 l’l).-When a current of air containing a constant proportion of carbon dioxide is drawn over a free surface of a solution of sodium hydroxide the rate of absorption increases with the velocity of the air current up to a certain speed beyond which it remains constant. Further the rate of absorption is proportional to the partial pressure of the carbon dioxide within fairly wide limits. On these facts a method f o r estimating carbon dioxide in the atm’osphere has been based which has the advantage that it is unnecessary to measure the volume of air passed through the apparatus.The air is aspirated through the apparatus a t a rate greater than that required for maximum absorption and by being passed through a perfor- ated plate is caused to impinge in a turbulent stream on the surface of a standsrdised solution of sodium hydroxide which is titrated after the experiment. The constant of the apparatus having been determined once for all by a preliminary experiment in which the air is measured the proportion of carbon dioxide in a sample of air can be calculated from the time during which the current has passed and the amount of gas absorbed a correction being applied for the effect of change of tem- perature on the rate of absoi-ption.ANALYTICAL CHEMISTRY.859 Samples of air containing 0.04 to 18 parts of carbon dioxide in 10,000 have been analysed by this method and the results agree very satisfactorily with those obtained by the very accurate method of Reiset.

Tfie solution of the platinichloride need not always be evaporat,ed t o dryness with the formic acid in order to get a firm coat- ing of platinum. Ammonium salts behave similarly. If both potassium and amiiionium have to be estimated the latter must be first expelled by boiling with water containing magnesium or sodium hydroxide and titrating the distillate.The residue in the flask may then be used for estimating the potassium in the way described.

W. D. H. Composition and Analysis of Milk. 13. DROOP R1cHaroh.u ( A m l y s t 1905 30 385-329).-Tlie average composition of 15,920 samples of iiiilk siialysed during the year 1904 is given. The average amount of fat was 3.74 per cent. being a little lesj than tlint found in 1903 (Abstr. 1904 ii 523). A number of experiments was carried out with a view to ascertain- ing the correct volume of the divisions of ihe necks of the bottles used in Gerber's method Each division should have a volume of 0.126 c.c. and mill then indicate I per cent.of fat. The exact diameter of the neck is of no importance. The volume OF the f a t oblained in the Gerber method is about 1.025 the volume of the f a t in the milk. Neglect of the volume of the fat bztween the upper and the lower parts of tlie meniscus is partly compensated by tlie decrease in weight of t'he milk delivered by a n 11 C.C. pipette with increasing quantities of fat. The results of a sjrnpld of liumaii milk are given total solids 10.39 per cent ; fat 1-98 per cent. ; suga~s 6-40 per cent. ; .proteide 1.75 per cent. ; ash 0.26 per cent. The amount of fat in this sample is milch below the average. w. P. s. Occurrence in Milk Serum of Substances which react with Naphthalene-P-sulphonic Chloride.

The absence of hippuric acid in normal fresh milk was t h u s proved. The serum was then rendered alkaline and shaken for many hours with a n etliereal solution of naphthalene- /3-sulphonic chloride. After separating the ether the aqueous portion was acidified with hydrochloric acid and extracted with ether amiiioniuni sulphate being also added to " salt out " the amino-acid compounds. In no case could the presence of a n amino-compound or other substance reacting with the naphthalene-P-sulphonic chloride be detected in normal fresh milk.An extremely ininute quantity however of a nitrogenous substance was obtained the identity of whicli was not ed,allishcd. MT. P. s. Estimation of Fat and Water in Butter by Gerber's Method. A . HESSI. (Milchw.

The latter neither agree betweeu themselves nor with the quantities81 0 ABSTRACTS OF CHEMICAL PAPERS. found by the ordinary gravitrietric rriet,hocl. The author therefore concludes that both pieces of apparatus are useless for estimating water and fat in butter.Testing Lard and Butter. EDUARD POLESSICE (Cl,em.

When cold the residue is shaken three times with 10 C.C. of light petroleum of low boiling point the solution is repeatedly washed with water (to the second washing a little bnriurn chloride is added) and then filteretl and evaporated in R taretl dish. I'iire lard free from paraffin mill yield about 0.003 gram of resinous resi(1ue.When the imsaponifiable matter or crude cholesterol is intended for the phytosterol acetate tjest i t milst be first freed from any paraftin by washing with light petroleum. This also removes un- desirable resinous matters and leaves a residue richer in phytosterol. L. DE K. Detection of Cocoanut Oil in Lard. L. HOTOX (Chem C'eiitr. 1905 ii 1105 ; from Rev. i?etewt. fnlsific. 18 S5-86).-Five grams of the sample are heated with 10 C.C. of acetic acid of sp. gr. 1.055 at 60" and well shaken. When cooled to 40 the bottom layer is transferred to a flat dish. The operation is repeated and the bottom layer is collected in a second and thP top layer in a third dish.

A number of experiments are described in which i t WAS found that xcetanilicle may be volatilisecl during the evaporation of the chloroform solution unless special precautions are taken. Rcetanilide is vohtile a t a comparatively low temperature. It‘ the solvent be clistillecl frolu a flask and the residue dried below 60° the loss is slight and a constant weight is obtained after tmenty-four h017rs. The residue obtained from an ether or chloroform solution of acetanilide is not pure wet- anilide but fairly trustworthy results may be obtained if after t’lre solvent has been distilled off the flask is rotated until crystallisa tion sets in and the residue then dried a t 95” for two hours.W. P. 8. Volumetric Estimation of Pyramidone and Antipyrine in the Presence of‘ each other. GASTON IJEGURIEK ( A ? m Cl~inz. c~nzcd. 1905 10 392-393).-The picric acid method for the estimation of pyramidone alone (Abstr. 1905 ii $78) must be slightly modified if antipyrine is also present. The t w o substances are first precipitated together as previously described and the percentage weight of the precipitate obtainecl. A second qu:tn- tity of 0.231 gram of the sample is then dissolved in 10 C.C. of water ancl the alkalinity of the pyramidone exactly nentralised with N/10 sulphuric acid using heliarithin as indicator.Forty grams of N/2O picric acid solution are now added and the solution is titrated with N/10 potassium hydroxide solution after t’he addition of :L little phenolphthalein. Then 1’ - 1” is the percentage of pyramidone in the sample and by subtracting the value P from the pyramidone the 1)ercentage of autipyririe is ob- tained. w. I?. s. This weight may be termed P.

Compare Abstr. 1903 ii 509).-Coloured substances which yield colourless leuco-compounds may be readily trtrated by means of a solu- tion of titanium trichloride the dye itself acting as indicator. All operations must be conducted i n a n atmosphere of carbon dioxide or otlier non-oxidising gas. Good results have been obtained with indigotindisulphonic acid in presence of Rochelle salt. With indigos oE lorn grade it is necessary first to remove impurities by Grossmann’s method. Eosin A and Rhodamine I3 yield good results in the presence of Nochelle salt arid alcohol. Pnrarosaiiiline hydrochloride pararos- aiiilinetrisulplionic acid malachite-green crystal-violet tolusafranine indoin and methylene-blue have also been analysed. Hydrogen per- oxide may be estimated volumetrically by means of titanium trichloride the disappearance of the yellow colonr being taken as the end-point. Ammonium persulphate solutions may be estimated by adding an excess of titanium tricliloride and titrating this excess with ferric salts. Tin may be estiruated by solution in hydrochloric acid addition of an excess of ferric salt and titration of the excess with titanium tri- chloride. J. J. S.
