PHYSIOLOGICAL CHEMISTRY. Physiological Chemistry. 737 The Influence of Minimal Doses of Suprarenal Extracts on Blood-pressure. By BENJAMIN MOORE and C. 0. PURINTON (PJEiiger’s Archiv, 1900, 81, 483--490).-The authors doubt whether the substances separated from the suprarenals are those which cause elevation of blood-pressure. They are less active than the raw extract, and such minute doses of the active physiologioal substance produce738 ABSTRACTS OF CHEMICAL PAPERS. an effect on blood-pressure that a very small contamination of an in- active substance by the active one will lead to positive effects. The extract was made from the suprarenals of oxen by extracting them with 10 times their weight of water, This extract was freed from proteid by boiling after acidifying, and then diluted 1000-fold.A more active extract was obtained by precipitating with load acetate, and suhseqnently freeing from lead in t h s usual way. The active sub- stance is in the filtrate, not in the precipitate, and although the filtrate loses by such treatment 75 per cent. of the organic material in the original extract, it is much more active. The filtrate contains the chromogen, and loses its activity slowly on standing. Tho amount of organic material was estimated in the usual way. As small a dose as 2-millionths of a gram per kilo. of body weight mill in the dogproduce a considerable rise of blood-pressure. Smaller doses, down to 0.2-mil- lionths, produce a slight rise of pressure, usually followed by a fall. I n some animals, the fall was not seen. The question arises whether the fall is caused by another substance, but the probability is that one active substance will produce different effects with different doses.W. D. H. Changes in the Substances in the Blood which are Soluble in Ether, By RICHARD WEIGERT (P$iiger’s Archiv, 1900, 82, 86--100).-The substances present in the blood corpuscles which are soluble in ether diminish in amount by remaining in the warm, al- though air is excluded. This diminution of the ether extract is accom- panied by a rise in the amount of acids soluble in ether. The sub- stance in the blood which is soluble in ether, but diminishes in this way, is not fat, as stated by Cohnstein and Michaelis, and the change should not be described as lipolytic. In the blood-corpuscles and in the blood-plasma, there appears also to be a chemical process which leads t o an increase of the ether extract, Hydroxyl-ions of the Blood.By RUDOLF HOBER (Pjiiger’s Archiv, 1900, 81, 522-540).-The alknlinity of the blood is deter- mined by the amount of hydroxyl ions in it. These arise by the hydrolytic splitting of the alkali salts of the weaker acids, especially of carbonic acid. An estimation of the total quantity of these salts gives, therefore, no indication of the alkalinity of the blood. The alkalinity can only be estimated by methods which do not alter the chemical balance there present. It is measurable by electro-chemical methods, and can be calculated from the E.M.F. of a concentration chain for hydrogen ions, or for a chain of hydroxyl ions.The two methods give widely different results. Thip, however, does not depend on the variability of the dissociation constants of water, but on the fact that the hydroxyl ion chains behave in an irregular manner to the oxygen electrodes used. With hydrogen electrodes, the molecular concentration of hydroxyl ions in defibrinated ox-blood is about 0.1 -1 0 - 5. By AN. K. MEDVEDEFF (PJGger’s Archis, 1900, 81, 540--573).-The experiments recorded are limited to observations on the oxidising action of liver extracts on salicyl- W. D. H. W. D. H. Oxidation in Animal Tissues.PHYSIOLOGICAL CHEMISTRY. 739 aldehyde. A previous auto-digestion of the extract for periods varying from 18 hours to 6 days makes no difference to its oxidising power. Oxidation is therefore the result of the interaction of the aldehyde and the active material (oxidation-ferment) in the extract. This action is proportional to the square root of the concentration of the aldehyde, and directly proportional to the concentration of the ferment.It is proportional t o the square root of the concentration of the aldehyde, because this is the proportion of that substance which is dissociated in solution. This idea is worked out in great detail and at considerable length, and tbeoretical views put forward to explain the action of oxidising ferments in particular, and all ferments in general. W. D. H. Composition of the Fat of Human Chyle. By FRANZ ERBEN (Zeit. physiol. Chem., 1900, 30, 436-452).-The fat in the urine in a case of chyluria was investigated. This is regarded as equivalent to chyle fat.The following figures give the chief results. Elementarv analysis : C, 76.52-76.59 ; H, 11-88-12.11 ; 0, 21*37-11-55 per cent. ; specific gravity, 0.905-0.92 at 15" ; melting point, 44' ; solidification point, 26" ; acid number, 3.508 ; saponification number, 199579 ; ether number, 196.071 ; Reichert-Meissl number, 2.254 ; Hehner number, 94.92 ; iodine number, 54.42 ; melting point of in- soluble fatty acid, 44". The fat contains :-Free fatty acids, 1.6SO ; neutral fats, 95.987 ; lecithin, 0.500 ; cholesterol, 1.715 ; glycerol, 10.717 ; total fatty acids, 95-573 ; soluble fatty acids, 0.65 ; insoluble fatty acids, 94.92 per cent. The insoluble fatty acids consist of oleic acid, 58.4 ; hydroxystearic acid, 6.6 ; stearic acid, 25.0 ; palmitic acid, 9.0 ; myristic acid, 1.0.W. D. H. The Properties of Nerve under the Influence of Certain Poisons. By NICOLAI E. WEDENSKI (Eflilger's Archiv, 1900, 82, 134-1 91).-The main properties of nerve investigated were excit- ability, conductivity, and action-current. The last was detected either by the telephone or galvanometer. Tracings were also taken of the attached muscle. A certain stretch of the nerve was subjected to the local action of certain poisons in solution (cocaine, chloral hydrate, phenol, and chloralose). There is stated to be complete parallelism between the alterations produced of the functional pro- perties of nerve and those in its action-current. Some exceptions to this rule noted in the case of chloralose are only apparent and are due to the extraordinarily rapid return of function which occurs when the action of the poison is suspended.Action of Certain Ions on Ventricular Muscle. By D. J, Lmam (krner. J. Physiol., 1900, 4, 265-282).- The experiments were performed with strips of the turtle's ventricle, and the results of Loeb's experiments on rhythmic contraction of striped muscle, and gonionemus tissue apply very closely t o cardiac muscle. Sodium and not calcium is the stimulus for its rhythmic action, but a, pure sodium chloride solution is injurious at last ; calcium arid possibly potassium salts improve the rhythm by neutralising this injurious W.

Heart-strips mill not beat rhythmically in solutions of non- conductors like sugar and glycerol.By BERNHARD SCHONDORFF [with HEINRICH OFFERGELD] (Pjuger’s Archiu, 1900, 82, 60-85j.- The question whether glycogen can originate after feeding on a diet free from carbohydrates has been frequently investigated, but a critical examination of these researches from those of Claude Bernard’s onwards shows that not a single one is conclusive. Either glycogen might have remained over in spite of the previous starvation period, or the diet employed (meat, &c.) was not free from carbo- hydrate. I n the present experiments, frogs were used, and casein was the diet given to them; the result is stated to show with absolute certainty that no glycogen originates from a proteid which does not contain a carbohydrate group. Can the Whole of the Glycogen Present in an Organbe removed by Sufficiently Long Extraction with Boiling Water 3 By JOSEPH NERKING (PJIGyer’s Archiv, 1900,81, 636-640). -Calf’s liver was repeatedly extracted with boiling water until the wash waters were absolutely free from glycogen.The residue mas then extracted with dilute potash, when more glycogen was obtained. I n the two experiments recarded, the amount of glycogen which was not extractable by water was respectively 24.9 and 76.4 per cent, of the total quantity present. This confirms the view that the glycogen which can be extracted by water is free in the organ, whilst that which cannot, is in chemical combination. W.D. H. Origin of Glycogen From Proteid. W. D. H. W. D. H. Origin and Excretion of Oxalic Acid. By ERNST SALKOWSKI (Chern.Centr., 1900, ii, 131-132; from Berlin. klin. Woch., 37, 434-437).-The source of oxalic acid is not proteid, for increase of proteid food (casein) does not produce a rise in oxalic acid excretion, and the acid is not formed from proteid during tryptic or bacterial activity. Calcium oxalate is constantly found in the fsces, and in not unimportaut quantities in the bile. The source of oxalic acid is uric acid, and so, indirectly, nuclein ; the acid is formed by a process of oxidation. Whether the seat of action is the liver was the subject of some experiments which did not yield satisfactory results. The subject of alimentary oxaluria is also discussed.

By MARCELLIN P. E. BERTHELOT (Compt. rend., 1900, 131, 547-552).- Normal urine slowly absorbs oxygen from the air in quantity varying from 8 C.C. t o 20 C.C. per litre of urine. There is no alteration in the quantity of urea present, in the proportion of dissolved carbon dioxide, or in the acidity, and the absorption of oxygen seems to be due to, or connected with, the colouring matters or leuco. W. D. H. Solubility of Uric Acid in Nucleic and Thymic Acids.PHYSIOLOGICAL CHEMISTRY. 741 colouring matters of the urine. The fact that urine is a reducing agent although formed from arterial blood shows that the function of the kidneys is not purely mechanical. By MARCELLIN P. E. BERTHELOT (Compt.rend., 1900,131,552-553).-The ratio of the acidity of urine as determined with phenolphthalein asindicator to that determined with litmus solution or litmus paper by the spot method, varies considerably. In one case it was 85 : 45, in another 52 : 16, and in another 126 : 14. These ratios are not affected by the absorption of oxygen by the urine. C. H. B. By OTTO NAEGELI (Zeit. physiol.

Excretion of Antipyrine by the Animal Body, By D. LAWROFF (Ber., 1900, 33, 2344-2346).--Antipyrine was administered in doses of 4-10 grams per diem to a full-grown dog weighing 35 kilos. The urine contained a glycuronic m i d , C17H2,,08N2, of which the crystalline compound of the bai4.m salt with barium chloride was analysed.C. H. B. Acidity of Urine. Estimation of the Acidity of Urine. M. 0. F. Hamolytic Serums, By JULES BORDET (Ann. Inst. Pccsteur, 1900, 14, 257-296).-The action of haemolytic serums varies con- siderably with the kind of animal employed, but in the same serum the alexin which causes destruction of bacteria is identical with the hsemolytic substance. The stromata of the corpuscles manifest towards such alexins a fixative power which is compared with what is seen in the case of staining reagents. It is possible to prepare an antitoxin antagonistic t o haemolytic serum ; this is anti-hsmolytic and anti- bactericidal. The action between the two substances appears to be that of chemical neutralisation.By PIERRE NOLF (Ann. Inst. Pasteur, 1900, 14, 297--331).-A number of experiments on the subject of agglutination are presented, and the mechanism of the process dis- cussed. Mixture of the serum of one animal with that of another often produces a precipitate, but the precipitating agent is not regarded as the agglutinating substance. By ELIE METCHNIKOFF (Ann. I n s t . Pasteur, 1900, 369-377) .-Hamolytic Serum and Red Corpuscles. By J. CANTACUZ~NE (ibid., 378-389).-Leucotoxin. By, BESREDICA (ibid., 390--401).-Action of Hamatoxin on Man. By ELIEMETCHNIKOFF and BESREDKA (ibid., 402-414).-The term cytotoxin is introduced for those poisoDs of animal origin which act on the formed elements (cells, &c.) of organs.The best known example is that contained in serum. The practice of transfusion of an animal’s blood into man has been abandoned because of the destruction of the red corpuscles so produced. The main experimental fact brought forward in this series of papers (which relate to the poisons which act, more or less specifi- cally, on the red and white blood corpuscles respectively), is that small doses, instead of producing destruction of the corpuscles in question, act W.

The Gonoooccus and its Toxin. By J. DE CHRISTMAS (Ann. lizst. Pmteur, 1900, l4,331--349).-The gonococcus in suitable media elaborates a toxin which, when applied in small doses t o the cerebral tissues, produces rapid death. This gonotoxin is not dialysable, it is destroyed a t 7 3 O , and [is precipitable by ammonium sulphate. If in- jected subcutnneously, an antitoxin is formed in the blood. The two sub- stances neutralise one another both in vivo and in uitro. Relationship between Chemical Constitution and Physiolog- ical Action. I. Physiological Action of Alkines of Piperidins. By CESARE PADERI (Chem. Centr., 1900, ii, 588-589 ; from Ann. Fcwm. Chim., 1900, 181-194). -The physiological action of piperyl- alkine and pipecolylalkine on frogs, rabbits, and dogs is similar to that of piperidine, whilst on the other hand, methylpipecolylalkine exercises a healing influence. Thus the introduction of glycol into the piper- idine molecule has no effect on the physiological action, no matter whether the glycol replaces a hydrogen atom of the imino-group or a hydrogen attached to the closed chain. When, however, a hydrogen atom of the piperidine ring is replaced by glycol, and at the same time a hydrogen atom of the imino-group replaced by the methyl group, tlie physiological action is completely changed.

742 ABSTRACTS OF CHEMICAL PAPERS, Chemistry of Vegetable Physiology and Agriculture. Researches on the Formation of Acetic Acid by Bacteria producing Lactic Acid. By CHR. BARTHEL (Centr.Bakt. Par., 1900, [ii 3, 6, 417-420).-The quantity of acetic acid prodliced during the lactic acid fermentation of milk varies only slightly with the con- ditions, the minimum being formed under those which are most favourable for the culture of the bacteria producing lactic acid. Acetic acid may be considered as a pathogenic product of these bacteria. R. H. P. Micro-organisms forming Dextran. By F. W. J. BOEKHOUT Centr. Bakt. PUT., 1900, [ii], 6, 161--165).-A new species of Sts-ep tococcus, named by the author 8. Iwrnensis, has been isolated from curdled milk, some water samples, and flowers, and has the power of converting media containing up to 20 per cent.of sucrose into a slimy niass with the formation of dextran. Peptone is the most favourable source of nitrogen €or the culture of these bacteria, which are capable of producing dextran even in the absence of oxygen. Schizomycetic Fermentation. By OSKAR E m E R L I N G (Ber., 1900, 33, 2477-2479. Compare Abstr., 1899, ii, 569).-A 10 per R. H. P.VEGETABLE PHYSIOLOGY AND AGRICULTURE. 743 cent. solution of milk sugar, when treated with Bacillus lactis aero- genes in the presence of calcium carbonate and nutritive salts, becomes turbid and evolves hydrogen and methane ; at the same time, a slimy precipitate is produced consisting of a mass of viscid threads. I n the presence of atmospheric oxygen the fermentation proceeds until a clear, viscid liquid is formed ; a t this stage, the filtered solution, on the addition OF alcohol, deposits a gaclactan, C,H,,O, ; this substance, a white, tasteless powder, reduces Fehling’s solution only after hydroly- sis with dilute acids, and yields mucic acid on oxidation with nitric acid.Viscid substances are produced in the fermentation of galactose by this bacillus, but their formation is not noticed in the case of dextrose, the latter sugar yielding acetic and inactive lactic acids. Mannitol, under similar conditions, yields large quantities of alcohol and succinic acid, together with traces of the volatile acids. G. T. M. Succinic acid is also a product of this fermentation. Chemical and Biological Researcb es on the Preparation of “ Sake.” By YOSHINAO KOZAI (Cents..Bakt. Pm., 1900, [ ii 3, 6, 385--405).--The preparation of ‘( sake ” can be divided into four stages, (i) preparation of the ‘ I koji ” (the “malt ”), (ii) preparation of the I ‘ mot0 ” (the yeast), (iii) the fermentation, (iv) the clarification and pasteurisation. The enzyme of the “ koji ” (Aspergillus oryxc~) forms dextrose from starch, dextrin, melitriose, sucrose, and maltose, but does not attack inulin or lactose ; 2 per cent. of alcohol acts in- juriously on the enzyme, which is completely inactive in solutions con- taining 28 per cent. of alcohol ; as, however, during the whole process of the preparation of “ sake ” there is never more than 18 per cent. of alcohol present, this enzyme must be still active in the later stages of the process.I n many samples of ‘‘ koji ” a white mould very similar to Lindner’s Suchisia suaveolens and Oidium lactis is found ; i t ferments sucrose, raffinose, dextrose, lavulose, or maltose, but not trehalose, rhamnose, lactose, or melizitose. The yeast of sake ferments sucrose, maltose, d-mannose, laevulose, dextrose, or methylglucoside very easily, trehalose or d-galactose with some difficulty, does not ferment lactose or rhamnose, and splits up melitriose into melibiose and lsvulose. It. H. P. Is the Formation of Enzymes a Trustworthy Characteristic of Yeasts 3 By ALBERT KLOCHER (CentF. Bakt. Pur., 1900, [ ii 3, 6, 241--245).-The experiments of Dubourg (Abstr., 1899, ii, 376) have been repeated and confirmed. The author disagrees with Dubourg’s interpretation of these, and considers that the formation of enzymes is the most trustworthy characteristic of yeasts.R. H. P. “ Chinese Yeast ” and the so-called Amylomyces (Mucor Rouxii). By CARL WEHMER (Centr. Bakt. Pccr., 1900, [ii), 6, 353-365)--“ Chinese yeast,” a preparation used in East Asia for starting the fermentation of rice, contains a mould, Mucor Rouxii, which can be cultivated in solutions of 13evulose, dextrose, galactose, sucrose, lactose, maltose, or inulin with peptone or ammonium nitrate, alcohol being formed in every case. R. He P.744 ABSTRACTS O F CHEMICAL PAPERS. Nitrification in the Soil of Forests. By W. MIGULA (Centr. Bakt. Par., 1900, [ii 3, 6, 365--370).-Nitrites and nitrates are not found except in minute quantities in the soil of forests. The author describes experiments in which such soil was inoculated with organ- isms which produce nitrites and nitrates.Nitrification did not take place in the upper layers, which contained decomposing leaves, but only in the deeper layers, zones of increasing intensity of nitrification being formed, which were different from the similar zones formed in arable land. The formation of nitrites, however, proceeded much more quickly in the cultures than the formation of nitrates. R. H. P. Occurrence and Action of Proteolytic Ferments in Germ- inated Seeds. By WL. BUTEEWITSCH (Chem. Centr., 1900, ii, 386-387 ; from Ber. deut. bot. Ges., 18, 185-189. Compare Green, Abstr., 1887, 987, and Neumeister, ibid., 1894, ii, 290).-The results of the author’s experiments confirm those of Green (Zoc.cit.) in showing the presence in germinated seeds of a proteolytic enzyme which, like “ animal trypsin,” decomposes proteids with production of amides. An enzyme of this kind seems to be present in the axillary organs of seedlings of Lupinus Zuteus, and also (perhaps as zymogen) in un- germinated seeds of L. angustifolius. Among the products of decomposition, substances were present which yield ammonia when boiled with dilute hydrochloric acid as in Sachsse’s method for estimating asparagine or glutamine. N. H. J. M. By V. HARLAY (Compt. rend., 1900, 131, 623-626. Compare this vol., i, 511, 576; ii, 35, 233, 301).-Germinating lentil seedlings are extracted with water and chloroform and the filtered extract tested with the tyrosinase derived from Russuka delica.The freshly-prepared solution remains colourless, but after a fortnight’s digestion either alone o r with casein, it gives a marked coloration, the liquid becoming red and then brown. If the solution is boiled before the addition of casein, the colour reaction is considerably diminished, It is found that the boiled solution has a solvent action both on the casein and the coagulated albumin. These results point to the existence of tyrosine in the plant at the commencement of the experiment, a further quantity of this substance being formed during digestion a t the expense of either the vegetable proteid matters or the casein. Hence the proteolytic ferment of the germinating lentil is analogous t o the trypsin of animal tissues, since it gives rise to similar products during the digestion of proteids.Proteolytic Ferments of Germinating Seeds. G. T. M. Germination and Growth of Peas in Solutions of Salts of Fatty Acids. By OSKAR LOWNSON (Chew,. Centr., 1900, ii, 344, and 388-389; from Bot. Centr., 83, 1-12, and 33--43).-Instead of the usual nutritive solutions, the author employed solutions containing all the necessary bases in the form of formates, acetates, and pro- pionates respectively. Nitrogen was present in the form of theVEGETABLE PHYSIOLOGY AND AGRICULTURE. 745 corresponding ammonium salt, sulphur as carbon disulphide, and phosphorus in the free state dissolved in water (1 : 50,000). The results of the germination experiments showed that the salts of fatty acid retarded germination ; the percentage numbers of seeds which germinated were '77.5 in formates, 66.66 in acetates, and 10 in propionates. Carbon disulphide promoted germination, but somewhat influenced the subsequent development.Phosphorus only retarded germination slightly. The solutions of formates and acetates (but not propionates) proved to be very favourable to the growth of fungi and bacteria. N. H. J. M. Germination and Growth of Peas in Solutions of Salts of Fatty Acids. By OSKAR LOVINSON (Chem. Centr., 1900, ii, 681-682 ; from Bot. Csntr., 83, 209--224).-The plants grown in solutions of [salts of] formic acid lived on an average 52 days, whilst those in solu- tions of acetic or propionic acid lived 28 and 17 days respectively. The injurious effects of the compounds seemed to be diminished by gradually accustoming the plants to stronger solutions.The plants after becoming inured to solutions of [salts of] formic acid would doubtless be able to assimilate mineral and organic nutriment pro- vided that the strength of the solutions had been such as to prevent the emptying of the cotyledons; this also applies t o the other acids with certain limitations. The great length of life (80 days) and vigorous growth of plants grown in solutions of formates, prove that the plants are capable of obtaining their sulphur from carbon disul- phide and of assimilating phosphorus directly, and that the alkalis and alkaline earths do not require to be present in the form of ealts of mineral acids. E. W. W. Proteid Metabolism in Plants.By ERNST SCHULZE (Zed. physiol. Chem., 1900, 30, 241--312).-A large number of observations on the chemical composition of different parts of various plants at different ages are recorded. They are carried out on the lines of the author's previous work, and confirm the views he had advanced concerning proteid metabolism. The proportion betweon the amounts of proteid decomposition products (amino-acids, hexon bases, kc.), varies at different stages. The most marked change is a diminution in the quantity of leucine, tyrosine, and the simpler amino-compounds, and the simultarieous increase of asparagine, and in some cases glutamine also, as age advances. The theory that the proteids break up into asparagine and a carbohydrate is not confirmed. Asparagine appears to be easily utilised for proteid synthesis.Material for Plant Nutrition in Apples and Pears. By EDUARD HOTTER (Chem. Centr., 1900, ii, 484-485 ; from Zed. Zandw. Vem. Wes. Ost., 1900, 583-585).-By suitably manuring fruit trees their lives are prolonged, and weak trees strengthened. Analyses of 20 kinds of apples and pears showed that for every 100 kilograms of fruit about 70 grams of nitrogen, 35 of phosphoric oxide, 170 of potassium oxide, and 14 of lime are withdrawn from the ground. Fresh apples yield about 0.336 per cent. of asb, and contain 0,076 of W. D. H.7-G ABSTRACTS OF CHEMICAL PAPERS, nitrogen, whilst pears give 0.301 of ash and 0.069 of nitrogeii; calculated on the dry substances, these data become, for apples, 3.24 and 0.47 per cent.respectively, and for pears, 2.01 and 0.46. The following analyses of the ash of apples and pears are quoted, the figuresin brackets referring to the pears: SiO,, 1.08 (1.55) ; SO,, 2.49 (5.02); P,O,, 10.42 (11.92) ; Fe,O,, 1.18 (0.98); CaO, 4.22 (4.73) ; By THOMAS BOKORNY (Chem. Zeit., 1900, 24, 771-772). -The presence of myrosin in plant substances may be conveniently proved by observing whether the addition of potassium myronate to about 1 gram of the material triturated with 5 C.C. of water at 30-40°, and contained in a small stoppered flask, develops the odour of mustard-oil within the course of 48 hours. Myrosin was thus detected in the seeds (except where otherwise stated) of the following plants. An asterisk denotes that potassium myronate or a glucoside which yields mustard-oil is already present.Cruciferce :-*Black mustard, white mustard, summer radish (Raphanus sativus), roots also, "Iberis amara, *I, umbellata, *I. semper- uirens, "scurvy grass (Cochlearia of.), *winter cabbage (Brassica oleracea), red, white, curly, a,nd turnip cabbages, wallflower (Cheir- apltlks cheiri), summer -stock, and "watercress (Nasturtium of,).

R. L. J. Bitter Principles of Hops. By GEORCI BARTH (Chem. Centr., 1900, ii, 681; from Zeit. ges. Brauw., 23, 509-513).-A sample of com- mercial lupulin gave 18.27 per cent. of ash, 63.93 of material soluble in ether, and 36.07 of lupulin husks. The portion soliible in ether contained 0.18 per cent. of wax, 11.55 of a-resin, 43.31 of p-resin, 0.17 of ash, and 8.72 of fat, oil, y-resin, &c.The portion insoluble in ether contained 15.31 of ash insoluble in hydrochloric acid, 2.75 of ash soluble in hydrochloric acid, 4.78 of proteid substances, 2.34 of pentosans, and 10.89 (by difference) of non-nitrogenous sub- stances, tannins, fibres, &c. The substances extracted by ether or light petroleum did not contain nitrogen. The quantity of sand in commercial lupulin varies from 10.9 to 20.2 per cent, E. W. W. Adlumia Cirrhosa-A New Protopine-bearing Plant. By JULIUS 0. SCHLOTTERBECK (Amer. Chem. J., 1900, 24, 249-253; and Ber., 1900, 33, 2799--2SOl).--The root of Aclhmia cirrhosa (climbingVEGETABLE PHYSIOLOGY AND AGRICULTURE. 747 fumitory) contains about 1 per cent, of protopine, whilst the leaves contain much less.Frzmarine is probably iden ticid with protopine, and since fumarine was discovered and named long before its discovery in opium by Hesse, the author is of opinion that the name protopine should be abandoned. E. G. An Alcornoco Bark known commercially as Jaborandi, and Alcornoco Barks in general. By C. HARTWICH and E. D~~NNEN- BERGER (Arch. Pharm., 1900,238, 341-352).--8 " jaborandi b u k " imported from Venezuela in 1888, was found, by botanical examina- tion, to belong in reality to a species of alcornoco ; it contained 16.6 per cent. of tannin. Further, several varieties of alcornoco barks were examined botanically, and, to a certain extent, chemically. In particular, from a specimen of bark denominated Cort. AZcornoco, the alcornin of Biltz, Erenzel and Spirgatis was isolated.This melts a t 2 0 5 O , and has a specific rotation + 33.83' ; a number of its coloiir re- actions are described. It has the formula C,,H,,O, and it yields a monoacetyl derivative ; consequently, it is an alcohol of the nature of phytosterol, and is better named alcornol. By GEORGE B. FRANKFORTER (C'hem. Centr., 1900, ii, 484; from Amer. J. Pharm., 72, 320-325).-- The unripe fruit of Astragalus caryocaipus has a bitter taste, which is probably due to the presence of an alkaloid, whilst the ripe fruit, on the other hand, has a peculiar, sweet taste. From the latter, a di- saccharose, astragalose, has been obtained in the form of a grey hygro- scopic powder. It melts at 95-98", reduces Fehling's solution, has a rotatory power [a],, + 38.5', and yields a phenylhydrazone melting a t 186-188G.Analysis of the latter showed it to be a hydrazone of a hexose. The rotatory power and properties of the sugar are, however, easily affected by change of conditions. A substance which contains nitrogen and gives the reactions of an alkaloid was also isolated from the plant extract. The Sea-weed Ulva Latissima and its Relation to the Pol- lution of Sea-water by Sewage. By EDMUND A. LETTS and JOHN HAWTHORN (Chem. News, 1900,82, 164--165).--UZua katissima, or sea lettuce, contains C, 35.15 ; H, 5.27; N, 6.25 ; 0, 37.96 ; ash, 15*37 (in which is S, 3.21 ; Fe, 290j per cent., and when fermented yields hydrogen, carbon dioxide, propionic, butyric, and, probably, acetic acids; later, the mass blackens from the ferrous sulphide formed, and hydrogen sulphide is disengaged. The weed abounds in polluted waters, and can thrive in and assimilate large quantities of nitrogen from sea-water charged with sewage and ammonia or nitrates; probably this is the cause of the high percentage of nitrogen in the plant.It is suggested that the presence of the weed in large quan- tities may perhaps be regarded as evidence of sewage contamination.

Physical Chern., 1900, 4, 553-569).-The toxic powers of solutions of acid sodium salts and of acids are compared by means of determinations of the concentra-748 ABSTRACTS OF CHEMICAL PAPERS, tions of solutions in which seedlings of Lupinus albus will just live.The acid sodium salts exert a far greater toxic influence than would be expected from the concentration of the hydrogen ions, and the authors hence conclude that the dissociation theory is unsatisfactory in explaining the toxic action of these acid salts. Digestibility of some Non-nitrogenous Constituents of certain Feeding Stuffs. By G. S. FRAPS ( J . Amer. Chm. Soc., 1900, 22, 543--552).-According to Ladd (A? York Agric, Ex@ Stat. Geneva Rep., 1889, 149), the sucrose and reducing sugars present in lucerne and mixed hay, wheat bran, maize, cotton seed, and linseed meals and oats are completely digested ; in turnips fed with mixed hay the reducing sugars were completely digested, but of the sucrose only 78.7 per cent.was digested. The results of the experiments now described showed that as a rule the sugars are completely digested. The examination of twenty-three samples of excrement obtained in digestive experiments showed that neither sucrose nor dextrose was present ; some of the ssmples con- tained reducing substances, but these do not seem to be sugars. The results of Stone’s experiments on the digestibility of pentosans (Agric. Science, 7, 6 ) in various foods (grasses, hay, sugar-beet, wheat bran, &c.) indicated that the average digestibility is 60.3 per cent. (compare also Lindsay and Holland, ibid., 8, 172). The author has determined the total pentosans, and also the pseudo- pentosans (that is, the constituents of the crude fibre which yield fur- furaldehyde) in several foods, and also their digestibility.Prom 0 to 21 per cent. of the pentosans consists of pseudo-pentosans, and in four out of five cases the pseudo-pentosans are less digestible than the pentosans of the non-nitrogenous extract. Of the nitrogen-free extract, 53 to 15 per cent. consists of sugars and pentosans. In the case of cow-pea meal, maize bran, and rice bran, the remainder of the extract consists of starch, which is more digestible than the pentosans; in the case of timothy hay and crab- grass hay, the order of digestibility is sugars, pentosans, residue. As regards the crude fibre, the pseudo-pentosans are less digestible than the residue. It seems probable that the crude fibre and undi- gested non-nitrogenous extract decompose in the intestines with pro- duction of gases, of soluble substances which are resolved, and of insoluble products which pass into the excrement and, being soluble in acid and alkali, appear in the analysis as non-nitrogenous extract.This would make the digestibility of the non-nitrogenous extract seem less, and that of the crude fibre greater than is actually the case. Attention is called to the importance of determining sugar in foods, and especially in hay and cotton seed meal. The determination of starch and pentosans is also of more importance than that of the crude fibre. N. H. J. M. Rye as Food. By WOLDEMAR YON KNIERIEM (Chcmm. Centr., 1900, ii, 394-396 ; from Landw. Jahrb., 29, 484-2523).-Crushed rye in conjunction with clover hay only slightly increases the yield of milk, but the rye seemed to have no injurious effect on the cows.When COWS receive sufficient f a t (in oil cake), rye increases the yield L. M. J.VEGETABLE PHYSIOLOGY AND AGRICULTURE. 749 of milk rather more than oats ; the amount of fat in the milk was diminished by rye. In experiments with sheep, it was found that with the exception of the non-nitrogenous extract, the constituents of rye are less digestible than those of oats ; the fat in rye is very slightly digested. Pigs con- sume rye very unwillingly after some time, and exclusive feeding with rye causes illness, from which, however, the pigs rapidly recover when fed with barley. Rabbits and poultry object t o rye. Rabbits digest much of the non-nitrogenous extract, but not the proteids.On the whole, rye may be advantageously employed for feeding if used with care, and in conjunction with sufficient digestible fat. N. H. J. M. Vetch Corn as Food. By WOLDEMAR VON KNIERIEM (Chem. Centr., 1900, ii, 396; from Landw. Jahrb., 29, 524--540).- Crushed vetches considerably increased the yield of milk, but dimin- ished the amount of f a t in the milk. No injurious effect was observed during six years. Rabbits digested vetches well, and the constituents showed higher digestion-coefficients than those of the various cereals. Pigs object to vetches alone, and soon cease togain in weight. This is attributed mainly to the high amount of proteids. As regards the taste of milk and butter, the results obtained with vetches were satisfactory; no bitter taste was noticed.Feeding Cows with Cane Sugar. By EBERHARD RAMM (Bied. Centr., 1900, 601-602; from Milch Zeit., 1899, 673).-As in the other feeding experiments (following abstracts), the cows received during each period : hay, 14 ; straw, 4.5 ; roots, 50 ; and brewers’ grains 4 kilos. per 1000 kilos. of live weight. I n addition, they received earth-nut cake and cane sugar respectively (6 kilos.). The rations con- tained the following amounts of digestible substances per 1000 kilos. live weight ; earth-nut cake ration : proteid, 4.12 ; fat, 0.93 ; and non- nitrogenous matters, 13.48. Sugar ration : proteid, 1.70 ; fat, 0.54 ; and non-nitrogenous matters, 15.65. As compared with earth-nut cake, it increased the live weight by about 1 per cent., diminished the yield of milk per day by 0.86 kilo.: and the yield of milk f a t and milk dry matter by 0458 and 0.133 kilo, respectively. N.H. J. M. By EBERHARD Ram1 (Ried. Cefitr., 1900, 29, 600-601 ; from Milch Zeit., 1899, 658).-The results of feeding experiments showed that, like maize bran (this vol., ii, 39), maize gluten, as compared with earth-nut cake increased the yield of milk, The percentage composition of the maize gluten mas found t o be as follows: nitrogenous matter, 35.90; fat, 1.85; non- nitrogenous extract, 31.80; crude fibre, 16.00; ash, 1.20; and water, 13-25. N. H. J. M. Feeding Cows with Malt-germ Molasses. By EBERHARD ZAMM (Ried. Centr., 1900, 29, 599-600; from Milch Zeit., 1899, 641).-Under the conditions of the experiments, malt-germ molasses N. H. J.

The malt-germ molasses contained : nitrogenous matter, 14.60; fat, 3.85 ; non-nitrogenous extract, 47.15 (including sugar, 25.05 ; crude fibre, 4.40 ; ash, 6-95 ; and water, 23.05 per cent. (compare this vol., ii, 502). Non-saccharine Matter contained in Molasses. By EBER- HARD RAMM and C. MOMSEN (Chem. Cewtr., 1900, ii, 489 ; from Milch Zeit., 1900, 433-436).--The effect of the non-saccharine portion of molasses when used as food was investigated by feeding five milch cows with the following series of foods. (1) Residual molasses con- taining about 41 per cent.of sugar ; (2) the corresponding amount of raw sugar ; (3) an equal quantity of raw sugar with the non-saccharine mud obtained in the process of removing sugar from molasses; (4) residual molasses as in (1). I n addition to these, a good basal ration mas used throughout the experiments. The molasses-mud was used as a substitute for the ash, nitrogenous and other non-saccharine components of the molasses. By making the fourth period like the first and using the same rations, the effects due to decreasing lactation were eliminated from the calculations. During the raw sugar period the milk was found to contain less fatty matter, whilst in the third period it increased by as much as 71 grams of butter fat per day per 1000 kilograms of body weight, and the milk had a t this time the highest specific gravity.The quantity of milk remained about con- stant in the first three periods and then decreased. Beans. By TAMAS KOSUTANY, RICHARD WINDISCH, E. VON H~RICS-T~TH, LADISLAUS VON SZ~LL and ADOLF FALTIN (Landw, Versuchs-Stat., 1900, 54, 463-479).-Analyses are given of Hungarian and French beans (compare Ballard, this vol., ii, 174); the results indicate that the Hungarian beans are the more nutritive, containing more proteids and carbohydrates, and less cellulose than the French beans. Bean oil, extracted by ether resembles olive oil in appearance. The oil, dried over sulphuric acid, has the following properties : Rp. gr., 0.9670 ; Hehner number, 78.5 ; Reichert-Meissl number, 2.46 ; K'dttsdorfer number, 135.4 ; iodine number (Kiibl), 119.9 ; refraction a t 2 5 O and 40°, 81.5 and 72.5 respectively.The oil contains fatty acid triglycerides, much lecithin and a good deal of sulphur.

As regards the fact that large amounts of nitrogen and mineral matter are taken from the soil and that no manure is required, the results of calcula- tions are given showing that, notwithstanding the large amounts oE cork and wood removed, only one-tenth of the total supply of the soil would be utilised in 1200 years.By M.

Ayr. prat., 1900, i, 527)-The yield of parsnip varies from 30,000 to 60,000 kilos. per hectare. The percentage com- position is as follows : Dry matter, 15.3 ; nitrogenous matter, 1.4 ; fat, 0-2 ; non-nitrogenous extract, 11.6 ; and cellulose, 1.2. As regards feeding value, the results indicate that parsnip is snperior to mangolds, turnips, and carrots.As indicated by the composition of the ash, parsnip requires abund- ance of phosphoric acid, potash, and lime. Parsnip is suitable €or feeding horses, cows, and bullocks. Effect of Difhent Potassium Salts on the Composition and Yield of Potatoes. By THEODOR PFEIFFER (Landw. VerszccldYtat., 1900, 54, 379-385. Compare Abstr., 1898, ii, 306).-A reply to Sjollema (this vol., ii, 305), in which the author shows that Sjollema’s results are not opposed to, but confirm, his own, which indicated that the injurious action of “ crude salts ” was due to the presence of mag- nesia, Other results obtained by Sjollema lend support to the author’s view that the different degrees of injury by potassium chloride on the yield of starch do not accord with the amount of chlorides found in the potatoes, but depend rather on the variety of the potato.

Oesterr, 1899, 2, 573).-From the results of 35 years’ experiments in pots and beds, the conclusion is drawn that it is possible to obtain quite normal plants in pots, and that such experiments furnish results of practical im- portance. The results of some vegetation experiments, which are given in detail, indicated that when loss of nitrate by drainage is impossible, the nitrogen left after the first year will increase the yield of barley considerably . The analytical results show that the composition of the barley grown in pots was normal, whilst as regards the size of the grain and the N.H. J. M.VEGETABLE PHYSIOLOGY AND AGRICULTURE. 753 relation of grain to straw, no essential difference was observed in the pot plants as compared with those grown in the field. N. H. J. M. By RICHARD OTTO (Bied. Centr., 1900, 29, 588-591 ; from GartenJora, 1899,48, 563).- Lettuce. The best results as regards yield and quality were obtained with farmyard manure. Sodium nitrate and kainite, both separately and mixed, do not seem favourable to the production of solid heads. The order of yield in the case of kohl-rabi, after the various manures, was (1) farmyard manure, (2) compost, (3) sodium nitrate and super- phosphate, (4) sodium nitrate and kainite, (5) sodium nitrate, super- phosphate and kainito, and (6) sodium nitrate.Non-nitrogenous manures alone did not greatly increase the yield as compared with the unmanured plot. Analyses of the plants obtained under the influence of the various manures are given. The percentage of nitrogen in the dry matter varies from 3 (without manure and with superphosphate alone) to 5.42 (with farmyard manure).

Agron., 1900, 26, 417-430).-1n 1884, a field which had been manured with 30,000 kilos. of farmyard manure per hectare received in addition 200 kilos. of sodium nitrate. On one portion of the land the nitrate was sown broadcast and on two other portions i t was distributed along the furrows, and in holes 40 cm.apart along the lines. The yield of roots on the three portions of the field was as follows : Nitrate sown broad- cast, 21,785 ; in the furrows, 38,392 ; and in holes, 40,337. Whilst the localisation of manures must depend on the nature of the manures themselves and on the crop, it is thought that the system may be generally adopted with advantage (compare Schlaesing, Abstr., 1893, ii, 141). Methods of Experiments on the Preservation of Farm-yard Manure. By THEODOR PFEIFFER, F. MOSZEIK, and OTTO LEMMER- MANN (Lccndw. Versuchs-Stat,, 1900, 54, 349--378).--The conflicting results hitherto obtained in experiments on the preservation of stable manure are, at, any rate in part, attributed to imperfect methods. The method now proposed is based on the fact that the nitrogen sup- plied in tbe food is completely recovered in the excrement after.deducting the amount deposited in the body and that of the milk wool, &c. The composition of t h e food and of the materials used f u r litter is therefore determined, as well as the composition of the faces, urine and milk. By determining ash constituents (phosphoric acid and potash), the amounts of which remain of course unaltered, i t is possible to ascertain how far the nitrogen results can be depended on. An important point which has to be considered is the extent of the loss of nitrogen in the manure before it is removed from the stalls (compare Muntz and Girard, Compt. vend., 1892, 115, 1318, and 116, 108). As regards the foods to be employed, mangolds and lucerne are to be N. H. J. M.75s ABSTRACTS OF CHEMICAL PAPERS. avoided. The authors propose meadow hay, dried beet.ront sections and crushed earth-nut cake, with straw for litter. The whole quail- tities of hay and straw required for the experiment are prepared before- hand and sampled. After describing the stalls and the arrangements for the solid and liquid manure, the sampling of the manure, and the analytical methods employed, the authors give in tables a number of results which show that the taking of samples can be made sufficiently accurate and that the feeding of the animals and the collection of the products can be conducted without loss. Street-dust as Manure. By ADOLFO CASALI (Bied. Centr., 1900, 29, 583-586 ; from &ax. sper. ital. agrar., 1898, 31, 377).-Street- dust is recommended as manure by Strabo, Pliny, and Columelln, and it was highly valued during the middle ages. The results of analyses of asample of sifted street-dust collected during a dry Sep- tember show that the material is suitable for soils poor in lime. It is also of use for the purpose of mixing with nitrogenous manures, both as a diluent and t o enable them to be uniformly distributed ; in the case of superphosphate, street-dust would be of use in diminishing the acidity. The author considers that street-dust is also of use in supplying R great vaiiety of microbes, derived partly from rain and partly from excrementitious matters. N. H. J. M. N. H. J. M.

75s ABSTRACTS OF CHEMICAL PAPERS. Analytical Chemistry. p-Nitrophenol as an Indicator. By LEOPOLD SPIEGEL (Bey., 1900, 33, 2640-2641. Compare Langbeck, Chem. News, 1881, 43, 161, and Wieland Abstr., 1883, llG’i).--The author recommends a 2-5 per cent. alcoholic solution of p-nitrophenol in place of methyl-orange in ordinary acidimetry and alkalimetry. The change from yellow when alkaline to colourless when acid is very marked, and the indicator is quite indifferent towards carbon dioxide. Sodium am- monium phosphate and crystallised borax may be estimated by the aid of the same indicator, but not fused borax. J. J. S. By G. 8. FRAPS (Amer. Chem. J., 1900, 24, 271-276).-The author has examined extracts of a large number of coloured flowers, leaves and fruits, and has found that, as a rule, the colouring matters are fairly sensitive as an indicator, giving one colour wben acid and another when alkaline.Abegg and Herz’s Method for the Separation and Recogni- tion of Acids. By WILHELM FRESENIUS (Xeit. ccnccl. Chem., 1900, 39, 566 -574).-With regard to Abegg and Herz’s systematic scheme Wide Occurrence of Indicators in Nature. E. G.ANALYTICAL CHEMISTRY. 75 5 (this vol., ii, 436), the author objects that the same necessity does not exist with acids, as with bases, t o separate them one from another before they can be identified, and that many of the reactions used by Abegg and Herz are untrustworthy. For instance, neither cyanogen nor arsenious acid is precipitated by calcium chloride under the conditions defined. Tartaric acid is only precipitated completely by calcium chloride when time is allowed for it to crystallise.The pre- cipitate is then very sparingly soluble in acetic acid, and may be easily mistaken for calcium oxalate. Calcium phosphate exhibits a similar behaviour with acetic acid. Boric acid finds no place in the scheme, and the difficulties resulting from the presence of silicates are not provided for. Other objections can be advanced t o themethods advocated for the detection of the halogens and nitric acid, and on the whole the scheme has but little practical value. Estimation of Potassium Perchlorate in Alkali Nitrates (Nitre and Chili Saltpetre). By N. BLATTNER and J. BRASSEUR (Chem. Zed., 1900, 24, 767).--Five grams of the dried sample are mixed with 7 to 8 grams of pure calcium hydroxide and heated in a.covered platinum or porcelain crucible for 15 minutes over a Bunsen burner. When cold, the mass is transferred to a measuring flask marked a t 138 C.C. and extracted for an hour with water. After making up to the mark (3 C.C. is taken as the volume of the undissolved matter), the liquid is well shaken and filtered through a dry filter. One hundred C.C. (4 grams of sample) of the filtrate are carefully neutrslised with dilute nitric acid using methyl-orange as indicator, and the chlorine is then titrated with silver nitrate as usual. After allowing for the percentage of chlorine present as chloride, the balance is calculated Process for the Estimation of Chlorides, Chlorates, and Perchlorates in the Presence of each other By N.BLATTNER and J. BRASSEUR (Chem. Zed., 1900, 24, 793).-The chlorine as chloride is first estimated as usual. It is then again estimated after reduction of any chlorate by boiling with sulphurous acid and finally after ignition with calcium hydroxide (see preceding abstract). The authors have not as yet found any chlorate in samples of Estimation of Potassium Iodide. By THOMAS S. BARRIE (Phmm. J., 1900, [iv], 11, 58).-When potassium iodide ( 5 grams in 20 C.C. of water) containing chlorides and bromides is treated with 5 per cent. solution of potassium dichromate (10 c.c.) and 10 per cent. sulphuric acid (10 c.c.), iodine alone is liberated. This is extracted with toluene or carbon disulphide, the solution shaken with a known volume of NjlO sodium thiosulphate solution and the excess titrated with standard iodine.Simple and Accurate Method for Estimating the Dissolved Oxygen in Fresh-water, Sea-water, Sewage Effluents, &c. By EDMUND A. LETTS and ROBERT F. BLAKE (Chem. News, 1900,82, 163--164).-An ordinary separatiug funnel is filled with the water to be examined and a measured volume withdrawn; a definite volume of M.

The stopper is inserted with the exclusion of air-bubbles, and the liquids are mixed together. After 15 minutes, the funnel is inverted, the stem filled with a mixture of equal volumes of sulphuric acid and water, the tap opened, and when all the iron hydroxide is dissolved the solution is titrated with permanganate or dichromate.Estimation of Oxygen in Copper by Ignition in Hydrogen. By LEONARD ARCHBUTT (Analyst, 1900, 25, 253--262).--Blount (Abstr., 1896, ii, 333) has described a process based on the reduction of copper oxide by hydrogen. The sample is melted in a current of dry hydrogen and the water collected and weighed. The author whilst acknowledging the accuracy of this process prefers to estimate the oxygen by the loss in weight which the sample suffers when ignited in hydrogen as has already been proposed by Hampe. Thirty to forty grams of the copper, best in the form of bright turnings small enough to pass through a tube 4-inch in diameter, are thoroughly cleansed with ether, dried, and introduced into a dry weighed bulb tube, which is then reweighed.The whole is ignited for about an hour in a current of purified hydrogen, and then allowed to cool in the current. When cold, tbe hydrogen left in the bulb tube is displaced by dry air and the tube reweighed. D. A. L. An illustration of the apparatus and bulb tube is given. L. DE I(. Detection of Free Phosphorus. By P. MUHERJI (J. Asiat. Soc. Bengul, 1900, 69, ii, 97--101).-The author has noticed that hydrogen generated in contact with free phosphorus becomes phosphorescent. The incompletely oxidised compounds of phosphorus yield, like phosphorus itself, a gas which burns with a green flame, but this is not luminous in the dark.The glow is lessened to some extent by the presence of much alcohol, ether greatly interferes with it, but is soon expelled, oil of turpentine stops it and should be first got rid of by washing the material with alcohol and then with water. Nitrous fumes, hydrogen sulphide, iodine, and oil of mustard in moderate quantities do not interfere. The apparatus in its simplest form consists of a flask fitted with a tap funnel and a jet. Common zinc and dilute sulphuric acid are introduced, and after making sure that the reagents cause no glow, the suspected article is added and the effect observed in a dark room. L. DE K. Estimation of Phosphorus in Coke and Coal. By J. M. CAMP (Chew. News, 1900, 82, 8-9).-The coke, powdered to pass through a 40-mesh sieve, is dried at 100" for an hour, and when cool 5 grams are exposed in a porcelain crucible in a mufie overnight ; the contents are, next morning, transferred to a platinum crucible, supported on a platinum tripod, on the top of the chimney of an Argand burner, and heated below boiling with 5 C.C.of dilute hydro- chloric acid (1 : Z), and 10 C.C. of dilute hydrofluoric acid until dry,ANALYTICAL CHEMISTRY. 757 further dried, but not baked, allowed to cool, and warmed with 15 C.C. of the dilute hydrochloric acid. The contents are transferred t o an evaporating dish, boiled for one or two minutes with 5 C.C. of strong nitric acid, filtered, treated with 25 C.C. of strong ammonia, then with sufficient strong nitric acid to exactly dissolve the precipitate, after which 5 C.C.more is added. Precipitation with molybdate follows, &c., and 1.63 per cent. of the dried precipitate is taken as phosphorus. D. A. L. Estimation of Phosphorus in Ores, Pig-iron, and Steel containing Arsenic. By J. M. CAMP (Chem. News, 1900,82, 9)- Five grams of pulverised dry ore are gently boiled for 30 minutes with hydrochloric acid, the solution diluted, filtered, and exposed on a steam-bath overnight. In the morning, 2 grams of pure oxalic acid and 50 C.C. of hydrochloric acid are added, the solution covered with a watch glass, taken t o dryness sharply, but not baked, then, when cool, evaporated with 30 C.C. of strong hydrochloric acid until the first appearance of insoluble ferric chloride, treated with 10 C.C.of strong nitric acid, and when violent action has ceased, warmed to complete solution, diluted, and filtered into a flask, washing with 2 per cent. nitric acid. The portion of the ore insoluble in hydrochloric acid is ignited, fused with mixed carbonates, dissolved in excess of hydrochloric acid, allowed to dry overnight in a steam-bath, moistened with dilute hydrochloric acid and enough hot water to dissolve chlorides, warmed, filtered, added to the contents of the other flask, and the phosphorus determined in the whole, in the manner described in the preceding abstract. The method is applicable to the analysis of pig-iron and steel. By FRED IBBOTSON and HARRY BREARLEY (Chem. News, 1900, 82, 55).-A solution of 2 grams of the steel in 45 C.C.of nit'ric acid of sp. gr. 1.2 is treated with permanganate until a pink colour or a precipitate of manganese dioxide persists on boiling; i t is cleared with ferrous sulphate and after the addition of 4 C.C. of strong ammonia is shaken while hot with 30 C.C. of molybdate reagent, then kept at 70--80° for a few minutes, passed through a pulp filter, and washed. The precipitate is dissolved in ammonia, treated with 10 to 12 C.C. of hydrochloric acid and 10 C.C. of a solution of lead acetate (40 grams to the litre), heated and well shaken with a mixture of 10-12 grams of ammonium chloride and 50 C.C. of strong ammonium acetate solutions ; the precipitate is filtered and weighed as lead molybdate. The process is applicable (with slight modifications) to pig-irons, nickel-steels and alloys, chromo-steels, tungsten-steels, spiegels and ferro-manganese (compare Abstr., 1899, ii, 337).D. A. L.

After 10 minutes, the liquid is decanted through a porce- lain Gooch crucible, and the precipitate is washed thrice by decantation with 50-70 C.C.and then on the filter with 200-260 C.C. of cold 1 per cent. nitric acid. Finally, the precipitate is ignited by placing the crucible inside a nickel crucible and heating the bottom of the latter to a dull red heat for 15 minutes as directed by Woy (Abstr., 1898, By JOHN K. HAYWOOD (S. Amer. Chem. Xoc., 1900, 22, 568-582; 705--706).-The author calls attention to the adulterations of ar- senical insecticides. These are readily detected by the usual methods. AS regards the 6ondfide articles they may be assayed as follows. Water may be determined in Paris or Scheele's green by drying for 12 or 15 hours a t 1 0 0 O . The total arsenious oxide is best estimated by the iodine process recommended by Smith (this vol., ii, 47). A good method for estimating copper in these substances is to titrate the iodine set free from potassium iodide in an acetic acid solution.I n order t o completely extract free arsenious oxide from Paris green, a very large amount of water is necessary. The author finds that 500 C.C. of water dissolve an appreciable quantity of the arsenical copper compound, and that, therefore, the amount of free arsenious oxide found will be in excess of the truth (compare next abstract). The amount of arsenious oxide, combined with the dissolved copper oxide, may be readily calculated from the amount of the latter.

To prepare the reagent, 140 grams of sodium carbonate, 20 grams of ordinary sodium phosphate, and 70 grams of freshly ignited molybdenum trioxide are dissolved together in 500 C.C. of water, 200 C.C. of nitric acid are added, the solution made up to a litre and filtered after 24 hours, To estimate potassium, an excess of the reagent is added, the mixture evaporated to dryness, the residue rubbed to powder, heated with dilute nitric acid (1 : lo), and, after cooling, the precipitate collected and thoroughly washed with dilute nitric acid. The phosphoric acid in it is then estimated in the usual way with magnesia mixture, but the ammonium magnesium phosphate may be titrated instead of being ignited.It is dissolved in nitric acid, and the solution neutralised with ammonia; 1 C.C. of acetic acid and some sodium acetate are added, and then a standard solution of lead nitrate (35 grams per litre) until a drop gives a yellow colour with potassium iodide. M. J. S. Shortened Method for Estimating Potassium in its Salts. By HUGO NEUBAUER (Zeit. anal. Chem., 1900, 39, 481-502).-The following process, if strictly adhered to in every detail, gives an accurate estimation of potassium in a solution which may contain sodium, magnesium, calcium, chlorides, and sulphates : T wenty-five C.C. of the aqueous solution of the substance (0.5 gram) are mixed with a few drops of hydrochloric acid and a small excess of platinic chloride, and evaporated on the water-bath just to dryness.After cooling, the mass is moistened with 1 c.c, of water and well rubbed with a pestle made from glass rod ; 30 C.C. of alcohol are then added in portions of 10 C.C. at a time, rubbing very intimately after each addition. After half an hour, the precipitate is transferred to an asbestos filter in a platinum Gooch crucible, and thoroughly washed with strong alcohol (93-96 vols. per cent.) and finally with ether. The contents of the crucible are next reduced by very gradual heating in hydrogen, or equally well in coal-gas (5 minutes below red heat and 20 minutes a t a very dull red), and then thoroughly washed with hot water.The crucible is then filled with 5 per cent. nitric acid, which is allowed to act for half an hour, returning it as it slowly percolates through the filter. The reduced platinum is again thoroughly washed with hot water, dried, ignited, and weighed. Multiplication by 0.48108 gives the corresponding weight of potassium oxide. Should barium be present, the reduction must not be performed with coal-gas, but with hydrogen ; with this exception, the process needs no altera- tion, and equally good results are obtained. By P.

Dudley and Pease’s process, titration OF the free alkali by means of N/lO alcoholic stearic acid, so as to avoid the troublesome filtration of the alcoholic solution of soap from any undissolved alkali carbonate. Two grams of undried soap are introduced into a round-bottomed flask, 50 C.C. of alcohol and a definite number of C.C. of N/lO alcoholic stearic acid, more than sufficient to neutralise any alkali present, are added, and also a little phenolphthalein. After boiling for half an hour under a reflux condenser, the excess of stearic acid is titrated with N/10 alcoholic soda and the total amount of alkali calculated. Another 2 grams of the sample are boiled with 50 C.C.of alcohol, a 10 per cent. solution of barium chloride is added in quantity just sufficient to decompose the alkali found, and the liberated barium hydroxide is then titrated with N/10 alcoholic stearic acid and phenolphthalein, the result being expressed as free alkali. The difference between the two titrations represents alkali car- bonate. L. DE K. New Volumetric Method for the Estimation of Silver. By LAUNCELOT W. ANDREWS (Amer. Chem. J., 1900, 24, 256--266).-The process is a modification of the one introduced by Pisani for the esti- mation of very small quantities of silver by means of a solution of iodine containing starch. The silver solution should contain not quite 5 per cent.of nitric acid and be free from mercury and the lower oxides of arsenic and antimony; any nitrous acid should be expelled by boiling, and sulphurous acid must be removed by addition of ferric sulphnte. A solution of ferrous sulphnte is added in such quantity that there shall be a t least as much iron as silver, and an equal quantity of iron as ferric sulphate is also added ; if the amount of silver should be more than 0.02 gram per 100 c.c., i t is best to first convert the iron sulphates into nitrates by judicious addition of strontium or lead nitrate. The starch-iodine solution is then run in from a burette until the colour of the liquid turns slightly blue, showing that all the silver is precipitated. This solution is best prepared by heating 9 grams of pure iodine and 50 grams of purified maize-starch with 100 C.C.of water in sealed tubes for an hour in a boiling water-bath. When cold, it is diluted to a convenient strength, say a N/20 or N/100 d u - tion. This should be standardised with silver nitrate ; estimation of the iodine by means of sodium thiosulphate would give erroneous re- sul ts. L. DE K. Gravimetric Estimation of Zinc as Sulphate. By WILHELM EULER (Zeit. anorg. Chem., 1900, 25, 146--154).-The estimation of zinc as sulphate is sufficiently accurate for ordinary work. The zinc solution, which must contain only sulphuric acid or acids which are volatile in the presence of siilphuric acid, is evaporated to dryness in a weighed platinum crucible and the residue cau.tiously heated a t a dull red heat to constant weight.The result may be confirmed by decomposing t,he sulphate Over the blow-pipe and weighing as zinc oxide. E. C. R.ANALYTICAL CHEMISTRY. 761 Lead and Cadmium Ferrocyanides. By EDMUND H. MILLER and HENRY FISHER (J. Amey. Chem. Soc., 1900, 22, 537-543).-The authors confirm Gay Lussac’s statement that lead ferrocyanide always retains more or less potassium ferrocyanide from which i t cannot be freed by washing. A number of experiments have shown that the amount of potassium increases with the acidity of the liquid, it being just the same whether there is an excess of lead or ferrocyanide. The results also agree closely with Low’s statement (Abstr., 1893, ii, 437) that a solution containing 10 grams of crystallised potassium ferro- cyanide per litre equals 0.01 gram of lead per c.c.; Furman has stated that 16 grams should be taken, but this figure is no doubt based on the erroneous conclusion t h a t the formula of lead ferro- cyanide may be calculat’ed from that of zinc ferrocyanide.Cadmium ferrocyanide thrown down from an ammoniacal solution has a composition agreeing with Hermann’s formula CdKe2Fe(CN),, but when precipitated from an acid solution, its composition lies be- tween that formula and the one proposed by Wyrouboff, K,Cd,[Fe(CN),],. This fact is also confirmed by Mackay (this vol., ii, 49), who states that it requires about 2.5 per cent. less potassium ferrocyanide to precipitate cadmium than would be required by the formula CdK,Fe(CN),.The results again contradict Furman’s state- ment that the cadmium standard may be calculated from the zinc Analysis of Lead and Tin Ores, also of the most important Lead and Tin Preparations, and their Commercial Products.

If a glass vessel is used, 2 grams of zinc must be taken. The reduced mass is collected on a weighed filter, dried and weighed ; the lead is then ex- tracted by means of dilute nitric acid, and the residual gangue weighed ; the metal may, of course, also be estimated in the filtrate as sulphate.Other lead ores and compounds may be assayed in a similar manner.

The mixture is shaken, gently warmed, and the excess of alkali titrated.

By EUGENE T. ALLEN and V. H. GOTTSCHALE (Arner. Chern. J, 1900, 24, 292-304).-The precipitate obtained by decomposing sodium or potassium aluminate with carbon dioxide is a basic aluminium carbonate of approximately the composi- tion OH=A1C0,,7A1(OH),,9H20, contaminated with small quantities of alkali carbonate; the latter is completely removed on boiling with water containing a little ammonium chloride or nitrate, the precipitate changing in this process to the hydroxide, The latter, prepared in this WRY, is dense and can be filtered and washed much more rapidly than the hydroxide precipitated by ammonia.The following method of estimating aluminium is more rapid than the old one, whilst at least as accurate. The substance is dissolved either in water or a mineral acid, in the 1:ittw case the excess of acid being nearly neutralised with ammonia ; a solution of 1 to 2 grams of potassium hydroxide, in which the amount of silica, iron, and alumina is known, is then added untilANALYTICAL CHEMISTRY. 763 the precipitate first formed is redimolved ; an excess of alkali should be avoided. Carbon dioxide is then passed in until precipitation is complete, 20 minutes, as n rule, sufficing for 0.2 gram of alumina ; the precipitate is for the most part transferred to a filter paper, washed with water, and then washed back into the original beaker, where it is boiled f o r 2 to 3 minutes with 150-200 C.C.of water containing a little pure ammonium chloride or nitrate. After settling, the precipitate is col- lected on a filter-paper, using a pump and cone, washed by decantation with hot water, burned, and, after heating for 10 minutes in the blowpipe flame, weighed ; the hygroscopic nature of alumina renders it necessary t o heat again, after the first approximate weighing, and weigh very rapidly. The method is as accurate as the old one for iron and alumina occurring together, and, with a large proport’ion of the latter, is pre- ferable; i t is accurate in the presence of sulphates, whilst the old method gives high results. When, however, alkaline earths or lithium are present, it is not applicable. Estimation of Alumina as Phosphate in Ore and Blast- f u r n a c e Cinder.By J. M. CAMP (Chem.

The mixture is heated to boiling, 8 C.C. of strong acetic acid and 15 C.C. of 20 per cent. solution of ammonium acetate are added, and the whole boiled for 10 minutes, allowed t o sub- side, the clear solution decanted, precipitated, filtered, and washed on the filter with hot water 10 times, but not more, as aluminium phosphate is slight,ly soluble.The precipitate is ignited in a platinum crucible in front of the muffle until the paper chars, then finished in the hottest part; 41.85 per cent. of the weight is alumina.

Chem. sbc., 1900, 22, 625-630).-Mitscherlich’s process, heating the ferruginous substances with a mixture of 3 parts of sulphuric acid and 1 part of water in a sealed tube from which the air has been expelled, gives utterly un- trustworthy results in the analysis of ferruginous rocks when sulphides are also present. Owing to the high temperature, 160-200°, to which the tube is exposed, the sulphur is oxidised a t the expense of any ferric oxide present and thus causes an apparent increase in the ferrous iron.The hydrofluoric method is not affected by the presence of moderate Estimation of Pyrrhotite in Pyrites Ore.

The sulphur present in the iron disulphide is subtracted from the total sulphur previously determined and the difference is calculated to pyrrhotite (Fe,S,). The presence of pyrrhotite may be ascertained by means of a magnet. I f zinc or copper sulphides are present in appreciable quantities an allowance must be made for the sulphur they contain. Zinc which is present as normal sulphide will be completely dissolved by the hydro- chloric acid.

The cobalt only is de- termined, usually by electrolytic deposition or precipitation as am- monium cobalt phosphate. The ores contain from traces to 8 per cent. I n the author's method 2.5 grams of pulverised and dry ore are dis- solved in hydrochloric acid, the solution evaporated to a syrup, and all soluble matter dissolved by adding water ; 100 C.C. of a saturated solution of ammonium chloride are then added and the whole diluted to 400 C.C. ; a solution of 1 part of strong ammonia in 15 of water is care- fully but vigorously stirred in until the liquid becomes deep red, when 5 per cent.solution of sodium carbonate is dropped in until the liquid has only a slightly yellow tint. A further dilution to 500 C.C. follows, the whole being well shaken and filtered. Four hundred C.C. of the filtrate are heated t o near the boiling point with 20 C.C. of satur- ated sodium acetate and 10 C.C. of acetic acid, and hydrogen sulphide is passed until nearly cold ; the precipitate of cobalt, nickel, and zinc sulpliides is filtered, washed with water containing hydrogen sulphide, dried, and ignited, then dissolved in hydrochloric acid with a little nitric acid, the latter being eliminated by twice evaporating with hydrochloric acid. The chlorides are dissolved in water, any iron removed by an emulsion of zinc oxide, the filtrate made up to 50 c.c., mixed with 10 to 15 C.C.of 10 per cent. hydrogen peroxide, then with 10 C.C. of 10 per cent. sodium or potassium hydroxide, boiled to remove excess of hydrogen peroxide, cooled, digested with potassium iodide and hydrochloric acid, and titrated with sodium thiosulphate (iodine x 0,4651 1 = cobalt).

Clarke’s method (ibid., 1894, [ iii], 48, 67) of separating nickel from cobalt by precipitating as ferri- cyanides and extracting the nickel with strong ammonia, are caused by the passage of cobalt ferricyanide through the filter and by the separation of sulphur in the subsequent precipitation of the nickel with ammonium sulphide.The method works well, however, if a few drops of a solution of alum are added before precipitating the ferricyanides, and if the nickel is subsequently precipitated with sodium or potassium hydroxide; in this way, less than a milligram of nickel can be clearly detected.

The hydrochloric acid solution is concentrated, boiled with some nitric acid to drive off hydrochloric acid, and then with large quantities of the same acid and potassium chlorate ; the precipitate is dissolved in hydro- chloric acid, the solution treated with ammonia and ammonium acetate, and the manganese precipitated with bromine. The chromium is deter- mined in the nitric acid solution by diluting and titrating with ferrous sulphate and permanganate.The phosphorus and carbon may be esti- mated in the usual way in separate portions of the steel. D. A. L. Estimation of Molybdenum in Steel and Steel-making Alloys. By FRED IBBOTSON and HARRY BREARLEY (Chem. News, 1900, 81, 269--371).-Steel, or ferromolybdenum, containing small propor- tions of molybdenum is dissolved in hydrochloric acid, in quantities of about 2 grams, and oxidised with nitric acid or potassium chlorate, the solution neutralised, or nearly so, with sodium ca,rbonate, avoiding the formation of a red coloration o r precipitate, and passed through a small pulp filter, which is then placed in a flask containing 2N sodium hydroxide t o the extent of 30-40 C.C. in excess of that required to precipitate all the iron. When the filter is disintegrated, the contents of the flask are heated nearly to boiling, well agitated, fractionally filtered, acidified with hydrochloric acid, and the molybdenum precipitated as lead molybdato in the manner previously described (Abstr., 1899, ii, 129).The presence of molybdenum in steel does not affect the estimation of silicon, or of manganese when no large excess of ammonium acetate is used to precipitate the iron, or when six instead of three separate lots of chlorate are added in the volumetric method by oxidation with potassium chlorate in nitric acid solution ; or of sulphur if the barium chloride is added to a distinctly acid solution; or of phosphorus if the long (acetate) method is followed, or in the rapid method when dissolving in ammonia and precipitating with magnesia mixture is adopted.Carbon in the residue obtained by treating the sample with copper solutions retains some molybdic oxide. I n the presence of molybdenum, iron cannot be estimated gravimetrically, or by simple solution and titration, but reduction with sulphurous acid and titration with potass- ium dichrornate or permanganate is effective. Nickel-molybdenum containing but little iron is dissolved in aqua regia, the solution poured into excessof ammonia, and the molybdenum precipitated from a portion of tho filtrate, whilst the nickel is determined in another portion cyano- metrically. If more than a few tenths per cent. of iron is present,a second precipitation is necessary, and the filtrates are mixed before determining the nickel and the molybdenum; with much iron, the molybdenum must be separated by means of sodium hydroxide as in the case of steels, and the nickel and iron separated afterwards in a fresh sample by means of ammonia.Molybdenum powders have been found to contain metallic molyb- denum and its oxide, tungsten and its oxides, silica, alumina, iron, ferric oxides, combined and free carbon, sulphur, and water.

I. Essence of Lemon and of Bitter Orange. By NEUMAN WENDER and GEORG GREGOR (Zeit. &alw. Genussm., 1900, 3, 449--459).--The article is chiefly a review of the various metho& in use for estimating the amount of alcohol and ethereal oils.Alcohol may be estimated by Schade's salt process, but the authors prefer the method proposed by Hefelmann (Abstr., 1897, ii, 605). I n many cases, the simple determination of the sp. gr. of the sample answers the purpose. Ethereal oil is best estimated by a process communicated by Mann which consists in observing the diminution in volume, when the sample is diluted largely with water containing a little sulphuric aeid, and then shaken with light petroleum. The solubility of the essences in water is determined by the authors as follows. One C.C. of the sample is put into a tall graduated cylinder and water a t 17.5" is gradually added with constant shaking until a perfectly clear solution is obtained.Admixture of oil of lemon or bitter orange or of citral may be detected by the lessened solubility in water, and the polarisation of the petrdeum extract. Vanillin may be isolated by evaporating off the alcohol, adding lead acetate, and shaking the filtrate with ether. The vanillin is then removed by shaking with dilute ammonia, the liquid is acidified with hydrochloric acid, and the vanillin again extracted wit,h ether ; finally, the phloroglucinol test is applied.

Detection and Estimation of Acetoacetic Acid in Patho- logical Urine.By V. ARNOLD (Chem. Centr., 1900, 345-346; from Centr. inn. Ned., 21, 417--423).-The characteristic test for aceto- acetic acid with diazoacetophenone described by the author (this vol., ii, 113) is best applied to urine previously decolorised with animal charcoal. All samples which give Legal’s acetone reaction also give a positive diazoacetophenone test. Ehrlich’s y-diazobenzenesulphonic acid cannot be used instead. Salts of acetoacetic acid differ from ethyl acetoacetate in their behaviour with the latter reagent ; they cause a light yellow colour, which turns deep red or dark purple on adding ammonia, whilst the ester gives an orange-red colour changed to pure red by ammonia. On the other hand, when using the author’s reagent, the ammoniacal solution of salts of acetoacetic acid is brownish- red with a similarly coloured precipitate, and that of ethyl acetoacetate vermilion-red with a similarly coloured, finely granular precipitate.The precipitates are soluble in strong hydrochloric acid, with a purple- violet colour. If the freshly prepared solution of diazoacetophenone is so much diluted that addition of ammonia does not cause a yellow coloration and a salt of acetoacetic acid is then added, a passing yellow coloration is observed gradually turning into a dark purple violet, which, after a few minutes, fades and turns yellow again; ethyl acetoacetate gives at once a reddish-yellow coloration, According to the author, acetone does not pre-exist in urine; the Estimation of Potassium Hydrogen Tartrate in Wine. By LOUIS MAGNIER DE LA SOURCE (Chem.Centr., 1900, ii, 692 ; from Ann. Chim. anal. appl., 5, 281).-In attempting to estimate the potassium hydrogen tartrate by Berthelot and Fleurieu’s method (precipitation by a mixture of alcohol and ether), complete precipitation is not obtained unless there is an excess either of tartaric acid or of a potassium salt. The author recommends that the latter should be added in the form of potassium bromide, of which a large excess is not injurious. M. J. S. By ALBERT HILGER (Chem.

Uric Acid and Purine Bases in the Blood and Animal Organs. By WILHELM HIS, jun., and W. HAGEN (Zeit. physiol. Chem., 1900, 30, 350--383).-The estimation in the blood and extracts of organs of uric acid and the various purine bases is di6cult on account of the proteid present. The precipitation of guanine with ammoniacal silver solutions is hindered by small quantities of albumose ; if large quantities are present, they are partially precipitated with it. Removal of the albumoses by ammonium sulphate or by trichloro- acetic acid does not interfere with the subsequent precipitation of the bases by ammoniacal silver solution ; zinc sulphate, however, does ; but even with the ammonium sulphate method, there is considerable loss of the bases.Besides albumoses, other substances, such as nucleic acid, interfere with the results; in fact, in extracts of organs much worse results are obtained than in artificial mixtures. The lead acetate method, also, is untrustworthy. Much the same is true for uric acid, and the best results mere obtained by employing Stad- hagen’s method of extracting the organs with 0.5 per cent. sulphuric acid. W. D. H. Detection of Salicylic Acid in Presence of Citric Acid. By A. CONRADY and by OTTO LANGKOPF (Chem. Centr., 1900, ii, 596 ; from Apoth. Zeit., 15, 412, 462; Pharm. Centr., 41, 411, 464)-Langkopf (this vol., ii, 695) has stated that citric acid prevents the reaction between ferric chloride and salicylic acid, and recommends a pre- liminary extraction of the latter with a mixture of ether and light petroleum.CONRADY considers that the failure to produce a violet colour is due to reduction of the ferric salt, since it can be developed by adding an oxidising agent (nitric acid or hydrogen peroxide). LANGKOPF replies to Conrady that ferric chloride is not reduced by citric or tartaric acid, and denies that the violet colour is developed by adding nitric acid or hydrogen peroxide. CONRADY, in rejoinder to Langkopf, states that he worked with a 1 per cent. solution of salicylic acid, Langkopf having employed one of only 0.1 per cent., and admits that below 1 per cent. the addition of an oxidising agent is ineffectual. LANGKOPF states that the explanation of Conrady’s results is, that on mixing ferric chloride with citric acid, ferric citrate is produced which has no action on salicylic acid.The addition of any strong acid prevents the formation of ferric citrate. Conrady’s hydrogen peroxide probably contained free sulphuric acid. Detection of Sdicylic Acid in the Presence of Citric Acid. By J. E. GEROCR (Chem.. Centr., 1900, ii, 597; from Phalrrn. Centr., 41, 464)-With reference to the controversy between Langkopf and Conrady, it is to be observed that all soluble acids are capable of preventing the ferric reaction of salicylic acid if present in suffi- cient excess. The violet coloured substance is to be regarded as salicylic acid in which the hydrogen of a bydroxyl group is replaced M. J. S.770 ABSTRACTS OF CHEMICAL PAPERS. by triatomic iron, and it is not formed if another acid, even citric, is present, for which iron has a greater affinity.By A. KLETT (Chem. Centr., 1900, ii, 545 ; from PlLarna. Centr., 41, 452).- Jorissen's method for detecting salicylic acid in beer serves equally well for lemon juice. Ten C.C. of the juice are mixed with 4 drops of a 10 per cent. solution of sodium nitrite, 4 drops of acetic acid, and 1 drop of a 10 per cent. copper sulphate solution, and heated to boiling. Salicylic acid produces a blood red coloration, which is best observed just as the liquid begins to boil. Detection of Salicylic Acid in Milk. By P. Suss (Chem. Centr., 1900, ii, 545 ; from Pharm. Centr., 41, 437).-The presence of 0.2 per cent. of citric acid does not prevent the detection of 0.005 gram of salicylic acid in 100 C.C.of milk. One hundred C.C. of milk are coagulated by warming a t 80' with 1.5 C.C. of a 20 per cent. solution of calcium chloride, and the filtrate allowed to drop through 50 C.C. of ether, which is then evaporated in a porcelain basin and tested by running in from the edge 1-2 drops of dilute ferric chloride solution diluted with 10 C.C. of water.

Ned., 40, 3-4).-Three hundred C.C. of human urine are rendered alkaline with sodium car- bonate and evaporated to dryness. The residue is extracted twice with 150 C.C. of 96 per cent. alcohol on a warm water-bath, and the alcoholic filtrate evaporated to a syrup.This is dissolved in 50 C.C. of water, acidified with 10 C.C. of 20-25 per cent. hydrochloric or sulphuric acid, and shaken with 200 C.C. of ether containing 20 C.C. of alcohol; the ethereal layer is then shaken with 75 C.C. of water and finally distilled. The extraction is repeated four times, and the ether residues are then dissolved in 20 C.C. of water and introduced into a Kjeldahl flask. (If much colouring matter is present, it is removed by shaking the solution in a separating funnel with 15 C.C. of chloro- form.) The nitrogen is then estimated in the usual manner, and from its amount the hippuric acid is calculated. The process is attended with a loss of about 15 per cent. of the hippuric acid present, but suffices for the comparative clinical exami- nation of urine.L. DE I(. .; A Multiple Fat Extractor. By CHARLES L. PENNY (Amer. Chent,. J., 1900, 24, 242--249).-The apparatus is a modification of the Soxhlet extractor. Its essential part is a chamber made of a nearly horizontal brass cylinder 2 inches and a half in diameter and 30 inches long, wherein may be placed a semicircular rack holding 51 shallow capsules containing the samples to be extracted. The cylinder has a capacity of about 2400 C.C. The other parts of the apparatus are a vessel in which the extracting liquid is boiled by means of steam passing through lead coils, block tin condensers, and the usual syphon- ing arrangement. The milk is dried in the capsule with addition of coarse sand orANALYTICAL CHEMISTRY, 771 asbestos ; after being weighed, the capsule is placed in the extractor, ether, or better, light petroleum boiling below looo, being used as the extracting liquid.The capsule is then dried and reweighed, tbe loss representing the fat. Cream or butter must be absorbed in asbestos By A. REINSCII and H. LUHRIG (Zeit. Ncdw. Genussrn., 1900, 3, 521-524)- The authors communicate fifty experiments from which it again appears that milk, even before it actually turns sour, may apparently have lost as much as 0.6 per cent, of solids owing to decomposition. This does not, however, affect the sp. gr. of the milk,so that as a rule more trustworthy results are obtained by calculating the total solids from the sp. gr. and the fat than by a direct estimation. From this i t also follows that it is very risky to calculate the fat from the sp.gr. and the solids actually determined. When dealing with sour milks not more than 3 days old, the sp. gr. OF the serum should be taken as affording the only safe evidence as to the addition of water. It is also incidentally remarked that total solids cannot be accurately estimated in sour milk liquefied with By ALBERT E. LEACH (J. Amer. Chem.

After nearly filling with water, 4 C.C. of a ‘7 per cent. soIution of copper sulphate are added and the whole is whirled, preferably without heating, to make the precipitate settle.The supernatant liquid is then drawn off with a pipette, over the bottom of which a small wisp of absorbent cotton is first twisted to serve as a filter; this is afterwards wiped off into the bottle by rubbing against its inner side.

In the first experiment the butter was inoculated with the fungi and exposed in thin layers to moist air in the dark. After three months the various portions and also the non-inoculated original were analpsed in the usual way.From the figures recorded i t appears that the effect of the different fungi is practically the same; the only figure seriously affected is the acidity number, which mas raised some 24 degrees. In another experiment which lasted one year, the sample was inoculated with Mucor mucedo and the only figures notably affected were the saponification and ether numbers and the molecular weight of the free volatile acids.

By DIOSCORIDE VITALI (Chem.

The residual aqueous liquid is filtered while hot, made feebly alkaline with potassium hydroxide, and shaken with ether. The ethereal solution when evaporated leaves a colourless residue of sulphonal, easily recognised under the microscope by the characterist,ic dendritic form of its crystals. The reactions proposed by Schwartz, Vulpius and others depending on fusion with alkali are not character- istic as they are produced by other sulphur compounds. Sulphonal may, however, be detected by the following reactions. The substance is heated with three parts of powdered potassium hydroxide, when the liquid becomes yellow, then red, and the colour changes to blue on adding water.On acidifying with hydrochloric acid, an ephemeral violet colour is produced and sulphur separates, whilst sulphur dioxide is evolved, and a sulphate can be detected in the solution. The thiosulphate formed can also be recognised by adding potassium nitrite and an acid, when a transient, yellow colour is produced by the solution of nitric oxide in thiosulphuric acid. That a polysalphide is also formed can be shown by adding sodium nitro- prusside.

Compare this vol., ii, 328).-The author has shown that the well-known insolubility of glycyrrhizin in dilute sulphuric acid is not due to a chemical combination.Pure glycyrrhizin can only be obtained by extraction with alcoholic sulphuric acid, coupled w i t t purification by acetone as described in the first paper. More glycyr- rhizin may apparently be extracted by means of ammoniacal water, but in that way an impure product is obtained. All samples do not yield By GEORG GREGOR (A'eit. Nahr. Genussm., 1900,3, 460--471).-The author has proved that the plant (Cupsicurn unnuum) does not assimilate barium or lead salts when either of these has been purposely added to the soil. Should salts of these metals be found in the commercial article, i t may be safely assumed that they have been wilfully added. It is also stated that the only way of ascertaining the genuineness of cayenne pepper (the ground fruit) is by a thorough microscopic examination. A somewhat high ash does not necessarily point t o adulteration ; should it, however, amount to 10 per cent., it is as well to treat it with hydrochloric acid and test both the soluble and insoluble Estimation of Santonin.By KARL THAETER (Arch,. Phcwm., 1900, 238, 383-387. Compare Abstr., 1898, ii, 59 ; 1899, ii, 619 ; this vol., ii, 122, 583).-The loss in the author's process is not more than about 10 per cent. As a further improvement in the method the recommendation is made that, after the boiling with milk of lime, the alkaline liquid should be slightly acidified with sulphuric acid, and warmed until crystals of santonin begin t o separate, before t h e solutjon of aluminium acetate is added, an equally pure product.L.

Xoc., 1900, 22, 582--588).-The author communicates his experiences with some of the recognised methods for the detection of coal-tar colours in foods. Arata’s ‘‘ wool process ” is satisfactory ; it is, however, preferable to apply the confirmatory tests to the wool itself and not to the colouring matter obtained from it, because some coal-tar dyes are not properly extracted by amyl alcohol from an alkaline solution. It is also pointed out that some natural colouring matters such as chlorophyll merely form a coating on the wool which may be easily rubbed off, whilst coal-tar colours act as true dyes.Girard and Dupre’s processes (removal of the dye with amyl alcohol either from an alkaline or acid solution and treating the alcoholic extract with wool) give good results. Girard’s process for acid magenta (treatment with potassium hydroxide and mercuric acetate and then acidifying the filtrate with sulphuric acid) is useful in the examination of fruit juices and syrups but unsatisfactory in the case of jellies. Cazeneuve’s mercuric oxide method, although to be recom- mended for wines, is not satisfactory for the examination of jellies but Detection of Indican in Pathological Urine. By A. KLETT (Chem. Zeit., 1900, 24, 690).-Ammonium persulphnte is much better than bleaching powder as a reagent for indican in urine.A crystal of ammonium persulphate is added to a mixture of urine (10 c.c.) and 25 per cent. hydrochloric acid (5 c.c.), and the mixture shaken with chloroform; the imparting of a blue colour to the latter proves the presence of indican, Ehrlich’s Diazo-reaction. By G. WESENBERG. (Chern. Centr., 1900, ii, 67-68 ; from Apoth. Zeit., 15, 326--328).-The reagent is generally prepared as follows. One gram of sulphanilic acid is dissolved in water containing 50 C.C. of hydrochloric acid and diluted to a litre. When required, 10 C.C. of the solution are mixed with 2 C.C. of a 0.5 per cent. solution of sodium nitrite, and 10 C.C. of the mixture followed by 2.5 C.C. of ammonia are then added to 10 C.C. of the urine to be tested, and the whole is vigorously shaken.If a reaction is obtained and the red liquid exposed to the air for 24 hours, a greenish deposit is obtained, but it often fails t o form in cases of tuberculosis. The author advises that no alterations should be made in the appli- cation of the test. It is stated that the diazo-reaction may be caused when naphthalene has been administered ; bilirubrin also gives the test, and should be removed by a preliminary treatment with lead acetate or animal charcoal. On the other hand, preparations of Ehrlich’s Diazo-reaction for the Recognition of some recently introduced Morphine Derivatives. By LUIGI CARCANO (Chem. Centr., 1900, ii, 2 8 8 ; from Boll. Chim. $’arm., 39, 425-428)- Ehrlich’s reagent in the presence of ammonia (see preceding abstract) acts on heroine (diacetoxymorphine), forming a red, crystalline azo- compound of the formula NH,*SO,* C,H,*N,* C,IH2,0,N.Morphine may, perhaps, answer for fruit juices and syrups. L. DE I(. J. J. S . tannic acid seem to prevent the reaction. L. DE I(.ANALYTICAL CHEMISTRY. ‘77’1 gives a similar wine-red but less intense coloration. The reagent is particularly useful for the detection of small quantities of dionine (morphine ethyl ether) in codeine (morphine methyl ether). 0.01 gram of the suspected substance is dissolved in 1 C.C. of water, a few drops of ammonia are added, and then Ehrlich’s reagent drop by drop. Pure codeine gives a fine yellow, but dionine a red colour. Narcotine, narceine, papaverine, and thebaine give either a faint yellow colour or Assay of Opium.By J. B. NAGELVOORT (Pharm. Weekblad, 1900, No. 24, l-S).-The acidimetric process introduced by Prescott and Gordin (Abstr., 1899, ii, 714) is recommended. No morphine is re- moved from the sodium chloride mixture by treatment with benzene, which merely dissolves the inferior opium alkaloids. The results are generally higher than those obtained by the gravimetric process of the U.S.P., but the difference is not always as high as 3 per cent. A drawback to the method is the long time it takes, also the great waste of alcohol and chloroform, but these might be recovered by Modifled Alkalimetric Method for the Valuation of Opium, and other Pharmaceutical Drugs and Preparations that con- tain Alkaloids. By HARRY M. GORDIN (Arch. Pharrn., 1900, 238, 335--341).-The method already described (compare Abstr., 1899, ii, 714, but especially this vol., ii, 110) has been modified slightly.N/40 sulphuric acid and N/40 potassium hydroxide are used, in place of Nl2O solutions, in the titration of the alkaloid, which may be extracted in any suitable manner. If it has t o be extracted from a solution alkaline with potassium hydroxide, say by shaking with a mixture of ether and chloroform, the extract will contain a little alkali, and must be freed from this before it is evaporated, best by shaking with a little ignited magnesia and filtering. I n the case of alkaloids which dissolve with difficulty in very dilute acids, such as strychnine and hydrastine, it is better not to evaporate the ethereal solution, but to shake it with the excess of acid, and then distil off the ether cautiously before titrating. The method was applied to opium (1 C.C.N/40 acid per gram of the sample = 0.71 per cent. of morphine), nux vomica (1 C.C. N/40 acid = 0.0091 gram alkaloid, reckoned as equal parts of strychnine and brucine), and cinchona bark (1 C.C. AT/40 acid = 0.0077 gram alkaloid reckoned as equal parts of quinine and cinchonidine), and also to the commercial extracts of the last two substances and of Hydrastis camdensis. C. F. B. Action of Iodine on Aconitine and Caffeine. By CARL KIPPENBERGER (Zed. anal. Chem., 1900, 39, 43&-450).-The author has endeavoured to extend t o aconitine and caffeine the methods of titration based on the formation of alkaloid periodides (hbstr., 1886, 283, 682; 1899, ii, 534, 584).With caffeine, the presence of a con- siderable amount of free mineral acid is essential to the precipitation of the periodide ; a portion of the caffeine always escapes precipitation, but this may be reduced to inconsiderable traces by using a large excess no reaction a t all. L. DE K. distillation. L. DE I<.778 ABSTRACTS OF CHEMICAL PAPERS. of the iodine solution. The amount of iodine consumed varias with the conditions of the titration ; i t generally approximates to 4 atoms for one molecule of caffeine, except in the case where the alkaloid hydro- chloride is converted into hydriodide by a solution of silver iodide in potassium iodide (Abstr., 1896, ii, 682), when i t is very close to 2 atoms. The iodine solution must therefore be standardised against weighed caffeine under conditions identical with those of the titration. Aconi- tine can be better estimated by alkalimetric titration (this vol., ii, 637) than by means of iodine.Estimation of Nicotine, Amount of Nicotine in New South Wales Tobaccos. By G. HAREER (Chem. News, 1900, 81, 273). -Kissling’s and Biel’s methods give similar results ; but the modifica- tion of the latter involving the weighing of the double sulphates of nicotine and ammonia, and also attempts to estimate nicotine volumetrically in presence oE ammonia, have not proved successful. No loss of nicotine has being observed during the evaporation of its ethereal solution. Four varieties of New South Wales tobaccos gave the following percentages of nicotine :-Manilla, 1.95 ; Tamworth, 2-36 ; Tumut, 3-84 ; Bathurst, 4.53.Estimation of Strychnine. By E. H. FARR and ROBERT WRIGHT (Pharm. J., 1900, [iv], 11, 82-85).-1n view of Schweissinger’s criticisms (Pharm. J., 1885, [iii], 16, 447), the authors have examined the pharmacopcxial process for the assay of nux vomica preparations (compare Dunstan and Short, Abstr., 1883, 689, 11 75). Strychnine ferrocyanide is not quite insoluble in water acidified with sulphuric acid, and if precipitated in presence of brucine, the latter can never be entirely separated. If the amount of brucine is large, this alkaloid may form more than half the precipitate; almost the whole, however, can be removed by washing with acidified water, The authors recommend that not more than 5 C.C.of the liquid extract or 30 C.C. of the tincture should be assayed, and t h a t 200 C.C. of wash water at a stated temperature (38’) should be employed, a correction being made for the strychnine dissolved by it. Behaviour of Proteids to Alkaloid Reagents, and a Method of Estimating Combined Hydrochloric Acid. By OTTO COIIN- ~ E I M and H. KRIEGER (Zeit. Biol., 1900, 40,95-116).-The combina- tions of albumoses and hydrochloric acid which are formed in the stomach are salts which react acid to litmus, phenolphthalein, and other indicators, and neutral to Congo-red, methyl-violet, &c. If a mixture contains only hydrochloric acid and such acid proteoses, the use of such indicators enables the free acid to be estimated; but this is not the case with the contents of the stomach, where salts and other acids are also present.For the estimation of acid-proteoses, salting- out is a method which was found impracticable, but certain alkaloid reagents precipitate them readily. Sodium phosphotungstat e, for in- stance, will not precipitate proteid, but it will precipitate proteid which is combined with hydrochloric acid. In this, proteids resemble Hantzsch’s pseudo-ammonium bases. Various alkaloid reagents were tested with artificial mixtures and stomach contents, The results 31. J. 8. D. A. L. R. L. J.ANALYTICAL CHEMISTRY. 779 with calcium phosphotungstate and potassio-mercuric iodide were satisfactory, and agree well with those obtuiued by Sjoqvist’s more complicated method. W. D. H. Modification of Ritthausen’s Method of Determining Proteids.By F. BARNSTEIN (Landw. Versuck-Stat. 1900, 54, 327-336).--Instead of gradually adding sodium hydroxide until the solution is neutral, i t is proposed t o add a definite volixme of aqueous sodium hydroxide, insufficient to completely precipitate the copper. I n this manner, the difficulty of exactly neutralising coloured liquids is avoided, and there is a further advantage that the precipitate settles quickly, whilst the liquid filters more easily than is the case with Stutzer’s method. The substance is boiled with 50 C.C. of water, or, if starchy, is heated for 10 minutes in a water-bath, treated with 25 C.C. of a solu- tion of copper sulphate (containing 60 grams of the crystallised salt per litre) ; 25 C.C. of aqueous sodium hydroxide (12.5 : 1000) is then added, the liquid being stirred; the supernatant liquid is poured through a filter, the p’recipitate washed several times by decantation, and finally on the filter.Washing is continued until the solution no longer shows a reaction with potassium ferrocyanide or bariiim chloride. The nitrogen is then determined by the Kjeldahl process without removing the precipitate from the filter. A number of results are given agreeing very nearly with those obtained by Stutzer’s method. I n the case of tea, sugar-beet, lupins, and tobacco, however, somewhat high results are obtained ( + 0.07 to 0.19 per cent). The results of special determinations showed that asparagine, guanine, and betaine me not precipitated by copper hydr- oxide. Probably the malt-germ extract with which the substances were mixed kept the guanine in solution (compare Bosshard and Schulze, Lundw. Versuchs-Stat., 1887, 33, 132). Tobacco which had been boiled with 40 per cent. alcohol, acidified with acetic acid (Kellner, Landw. Versuchs-Stat., 24, 439) still gave a rather higher result (+ 0.09 per cent). than by Stutzer’s method. The new modification is, however, suitable for most purposes, As regards peptones, it was found that both with vegetable and animal albumin the precipitation was not complete, but in the modifi- cation adopted by the author the copper precipitate contained more nitrogen than was obtained by Stutzer’s method. By HENRIK SCHJERNING (Zeit. anal. C‘hem., 1900, 39, 545---566).-1n continuation of earlier work on this subject (Abstr., 1896, ii, 631; 1898, ii, 271, 416, 658), the author inquires how far his proposed reagents, and those suggested by others, fulfil the three conditions (I) of giving clear filtrates and washings, (11) of invariably precipitating certain groups of proteids, (111) of precipitating no other nitrogeuous organic substances. The reagents investigated (in addition to his own) are (1) Bromine water (Abstr., 1898, ii, 320), (2) tannic acid, (3) Stutzer’s copper reagent prepared by Fassbender’s method (Abstr., 1881, 205>, (4) phosphotungstic acid. Experiments with about 20 different nitrogenous substances show that none of the proposed reagents conforms completely with condition The process is as follows. N. H. J. 31. Precipitation of Proteids.780 ABSTRACTS OF CHEMICAL PAPERS. 111, but that the author’s six reagents are by far the safest inasmuch as, with the exception of magnesium sulphate, they precipitate very few of these substances, and then in most cases in but small amount. On the other hand, many of these nitrogenous substances are precipi- tated, and sometimes in large amounts, by bromine water, Stutzer’s reagent, and especially by phosphotungstic acid, whilst in other cases precipitates are produced which pass through filter-paper, but would be retained if formed simultaneously with proteid precipitates. Uranium acetate in presence of phosphates and mercuric chloride precipitates ammonia from the acetate. The errors so produced can be avoided by precipitating the phosphoric acid by lead acetate (not in excess) at 50” before adding uranium acetate, or by heating the precipitate with magnesia, ; the precipitation of ammonia from its acetate by mercuric chloride is prevented by the presence of alkali chlorides, especially ammonium chloride, or the use of mercuric chloride can be avoided altogether by employing lead acetate, which throws down the same proteids. As regards the actual precipitation of proteids by the reagents mentioned, it is shown that bromine water causes very incomplete precipitation and is very liable to give turbid filtrates, that tannic acid and Stutzer’s reagent precipitate albumoses and peptones incompletely or not at all, and that phosphotungstic acid in some cases fails to conform with condition 11. Laszczynski’s proposal to coagulate the proteids by heating a t a pressure of 14 atmospheres is likewise shown to give very imperfect results. 1u cases where large amount’s of salts of the light metals are present all the reagents fail to give quantitative results, with the exception of magnesium sulphate, stannous chloride, and probably Stutzer’s reagent and tannic acid.
