614 ABSTRACTS OF CHEMICAL PAPERS. Physiologic a1 C h emi s t ry. Comparative Physiology of Digestion. I. Digestion of the Larva of Tenebrio Molitor (Meal-Worm). By WILFIELM BIEDER- MANN (PJEiiger’s A~chiu., 1898, 72, 105--162).-The paper is mainly anatomical and histological. The most important chemical points noted are, (1) the presence in the epithelial cells of tho mid-gut of a number of crystalline clumps, which are of proteid nature, and which function as ‘ reserve material.’ (2) The existence of an acid reaction in the upper half of the mid-gut; this is independent of the food taken, and is also found in the fasting condition. The contents of the lower part of the intestine are alkaline ; this corresponds with anatom- ical differences in the cells of the lining epithelium. The acidity is due to acid phosphates.(3) The juice contains an energetic amylolytic enzyme, converting starch into dextrose, and an inverting enzyme, but no cellulose dissolving enzyme (cytase) was discovered. The course of proteolytic digestion closely resembles that by trypsin ; tyrosine, but not leucine, crystals were separated out from the final products. Fats are split into fatty acids and glycerol; fat is not absorbed in the form of an emulsion. W. D. H.PHYSIOLOGICAL CHEMISTRY. 615 Gastric Digestion of Caseinogen. By FRANZ ALEXANDER (Zed. physiol. Chem., 1898, 25,42 1--429).-The products of peptic digestion were separated by Pick's method of fractional precipitation with ammonium sulphate. The results, on the whole, closely coincide with those he obtained with Witte's peptone.The peptones obtained do not give Millon's reaction. Some of the results appear to indicate that mixed with caseinogen is a small amount of an albuminate. W. D. H. Digestion of Caseinogen by Pancreatic Juice. By UGO BIFFI (Virchow's Amhiv., 1898, 152, 130--157).-Under favourable circum- stances, caseinogen is completely digested, about 4 per cent. of the weight of the proteid being removed as tyrosine. Casein-antipeptone has the percentage composition : C, 49.7 ; H, 7.2 ; N, 16.3 ; 0, 25.2 ; S, 1.3; otherwise, it shows the properties and reactions of fibrin- antipeptone; the proteoses also agree in their reactions with those obtained from fibrin. The phosphorus of the caseinogen is found in two forms in the products of digestion, namely, as phosphoric acid, and as a compound not precipitable by magnesia mixture.The amount of phosphoric acid increases with the duration of the digestion and the amount of ferment present. W. D. H. Behaviour of Proteids which contain Phosphorus, in Meta- bolism. By FRANZ STEINITZ (P'uge1"s Archiv., 1898, 72, 75-104). -The present experiments, made on dogs, were carried out in the usual way by analyses and comparison of the intake and output in urine and faces; the special point investigated, however, was whether proteids containing phosphorus lead to the laying down of phosphorus in the body. The proteids used were casein and vitellin ; in the case of vitellin, however, there was some doubt as t o whether it mas not mixed with lecithin. The phosphates passed in the urine are, of course, allowed for.The general result of the experiments is that a considerable proportion of the phosphorus is retained in the body ; the similar experiments previously made by Marcuse on casein led tzo the same result, but the proportion he found retained within the body was smaller. Relatively more nikrogen than phosphorus (compared to what is present in the casein given) is retained ; this proportion between nitrogen and phosphorus retained was smaller in the experiments in which vitellin was used, but greater than in those where nucleo-histon was employed. Control experiments were made with myosin, which was obtained almost free from phosphorus. Feeding with proteids containing phos- phorus appears to yield better results so far as the putting on of phosphorus is concerned, than feeding with phosphorus-free proteids plus inorganic phosphates.W. D. H. Metabolism during Thymus-feeding. By THEODOR COHN (Zeit. physiol. Chem., 1898, 25, 507-510).-1n the urine of dogs fed on calf's thymus, a crystalline sediment is found, which, on examination, proved to be allantoin. This substance is believed to be t h e end-link 45-2616 ABSTRACTS OF CHEMICAL PAPERS. in the series of products from nuclein; possibly it arises from the oxidation of uric acid. In man, no such sediment was found. W. D. H. Physiological Relationships of Ammonia, and the Rdle of the Liver in Metabolism. By SERGEI SALASKIN (Zeit. phgsiol. CyJLew,., 1898, 25, 449--491)-Arterial blood shows great constancy in the amount of ammonia in it.The blood of the portal vein contains large quantities during digestion (3.5 to 8.4 milligrams per 100 grams of blood); the blood of the hepatic vein contains about the same amount as arterial blood. The alimentary mucous membrane is richer in ammonia after a meal of meat than after one of bread and milk. The lymph during digestion contains less ammonia than arterial blood, whilst the other organs exhibit great variations in the amount they contain. Such observations lend support to the views of those physiol- ogists who believe in ammonia as st precursor of urea. In dogs with an Eck-Pawlow fistula, the ammonia in the blood, brain, and other organs goes up; the amount of urea falls, whilst that of am- monia increases in the urine. Ammonium carbamate is believed to be an important step in urea formation, but whether oxidising ferments play any important part in urea formation is left an open question; it, however, appears evident that the liver is not the sole seat of the process.Some observations on pathological cases in man are recorded which bear out the conclusions arrived a t by experiments on animals. W. D. H. Changes in the Blood after Removal of the Thyroid. By A. G. LEVY (J. PatAoZ. ccnd Bacteviol., 1898,5, 316-330).-The experi- ments were made on dogs. There is reduction in the number of red corpuscles and of hamo- globin, but this is not very intense or constant ; the white corpuscles, on the other hand, are increased, but the numbers from day to day fluctu- ate considerably. The specific gravity of the blood always diminishes, and the percentage of fibrin is invariably increased.The total solids are lessened, and there appears to be an increase in some non-proteid con- stituent ; the proteids and total nitrogen are diminished. Absorption of Iron in Man, By G. HONIGMANN (Virchow’s Am&., 1898, 152, 191--192).-Hoffmann’s experiments on animals prove that absorption of inorganic preparations of iron takes place in the intestine. The present observations on a patient with a fistula in the lower ileum, and in whom the large intestine was thus rendered functionless, show, from examination of the intestinal contents during the administration of f e r r u m citriczcin oxidatum, that Bunge’s hypo- thesis has no foundation, and that the alimentary canal, as far as the ileum has the power to absorb as much, is 0.33 gram of iron in two days.Iron in the Liver and Spleen. By J. EVERETT DUTTON (J. Pccthol. and licccteyiol., 1898, 5,331-33!)).-Histo-chemical and macro- chemical examination of museum specimens of liver and spleen from two cases of malaria shows that there is an enormous increase of the W.

By WILIIELM AUTENRIETH and ZOLT~N YON VAM~SSY (Zeit. plqsiol. Chem., 1898, 25, 440-44S).--It is shown that the normal phenylic and chlorophenylic phosphates are so decomposed in the animal body t h a t a decomposition product, a diphenylphosphoric acid of the common formula OP(OR),OH, is formed. W. D. H. The Urea-forming Ferment of the Liver. By OTTO LOEWI (Zeit. physiol. Chem., 1898, 25, 51 I--522).-Richet and others have stated that the ‘ surviving’ liver and extracts of the organ are capable of transforming amido-acids into urea. It is difficult to con- sider that such an action, if i t does occur, is a ferment action in the usual Sense of that term. Attempts to repeat the experiments with glycocine failed, no urea being formed ; there is, however, a formation of a nitrogenous substance, the nature of which is uncertain, but which resembles urea in some of its characters.By W. LUMMERT (Pjiiqer’s A~chiv., 1898, 71, 176--80S).-Froa? the researches of others, it appears pro- bable that animals are not capable of building up fatty tissue from proteids ; the following experiments were made to determine the quantity and nature of the f a t elaborated by animals from carbo- hydrates when fed solely on the latter and proteid matter deprived of fat. Each animal was starved until it had lost considerably in weight, in order to deprive the fat-cells of their contents, and was then fed on flesh, rice-starch, casein, and meat-extract. It was found that, although ducks and geese increased considerably in weight on this diet, hardly any adipose tissue was formed; dogs, on the other hand, produced large quantities of fat, which, when examined according to the direc- tions given in Benedikt’s ‘‘ Analyse der Fette und Wachsarten,” 3rd edition, 2897, gave values showing that the fats formed consist of the triglycerides of palmitic, stearic, and oleic acids, mixed in similar pro- portions t o those characterising other natural fats.Of special interest is the fact that in the fats elaborated from carbohydrates, neither hydroxy-fatty acids nor alcohols of the fatty series are present. I n the liver, no fat formation appears to take place under the con- ditions of diet described ; the amount of fat corresponded with that present in dogs after long periods of starvation.The substances extracted by light petroleuni from the dried liver of the dogs were found to constitute from 4.9-8.7 per cent. of its weight, and to con- tain from 23.3-34.9 per cent, of cholesterol ; the fat formed in the W. D. H. Formation of Animal Fat.618 ABSTRACTS OF CHEMICAL PAPERS. region of the spleen and the kidneys also contains from 13-22 per cent. of cholesterol. The blood yielded from 0-9-1.15 per cent. of its weight of solid sub- stances soluble in light petroleum, and judging from the acetyl-number, these apparently contain from 54-9-61 *3 per cent. of cholesterol ; i t would ;tppeaz that their amount is increased by a change from a pro- teid to a mixed proteid and carbohydrate diet, f a t being excluded.W. A. D. Formation of Uric Acid. By J. WEISS (Zeit. physiol. Chem., 1898, 25, 393-397).-0n the addition of certain fruits (cherries, grapes, kc.) to the author’s diet, the amount of uric acid in the urine diminishes, whilst that of hippuric acid (which normally is onlypresent in traces) in- creases. Experiments were then made with the individual constituents of fruits, namely, potassium hydrogen tartrate, tannic acid, sugar, and quinic acid, but the last named tlubstance was the only one which produced the rise of hippuric and fall of uric acid. Glycerol and lactic acid gave a negative result ; the urine throughout was acid. W. D. H. Oxidation of the Stereoisomeric Tartaric Acids in the Animal Organism. By ALBERT BRION (Zeit. physiol. Chem., 1898, 25, 283--295).-Pohl (Amh.exp, Path. Pharm., 37, 411) has shown that tartaric acid is only partially oxidised in the organism of a dog or rabbit, whereas substances such as erythritol, succinic acid, and malic acid, which might be expected t o give tartaric acid under the above conditions, are completely decomposed. The author has made a number of experiments on the oxidation of the isomeric tartaric acids in the organism of a dog, and finds that I-tartaric and mesotartaric acids are most completely oxidised, d-tartaric acid much less, and lea’st of all racemic acid. It follows, therefore, t h a t racemic acid is not split up into its components during its passage through the animal organism. Oxidation Changes produced by Animal Tissues. By WILHELM SP~TZER (Pjuger’s Archiv., 1898, 71, 596--603)-In con- tinuation of previous work, in which it has been shown that the oxidation changes produced by animal tissues and tissue extracts depend on the presence of nucleo-proteids (this vol., ii, 36), it is now shown that this is also true for the conversion of arsenious into arsenic acid.Hofmeister having advanced the opinion that urea can be formed by oxidation processes, the experiment of attempting to obtain urea by digestion of liver-extracts with various ammonium salts was made, but with negative results. W. D. H. By BALLAND (Compt. rend., 1898, 126, 1728-1 731).-The author has determined the moisture, nitrogen, fat, ash, and extractives in the uncooked flesh of 38 kinds of fish, &c. ; the results may be compared with those obtained by Miss Williams (Trans., 1897, 649) in the analysis of cooked fish, It appears that those fish which contain the least amount of water are the richest in fat, whilst those containing the least f a t are A.W. C. Composition of Fish, Crustacea, and Molluscs.PHYSIOLOGICATA CHEMISTRY. 619 the richest in nitrogen. Crustacea and molluscs contain, as a rule, By Huao TIEMANN (Zed. physio?. Chem., 1898, 25,363-392).-The colostrum of different cows differs in composition; the specific gravity varies from 1.0299 to 1.0594, and diminishes with each milking ; the amount of dry residue varies from 12.83 to 32.93 per cent,, but the greatest variation is in the amount of fat present. The nitrogenous constituents diminish, but the sugar increases, with successive milkings.The amount of true albumin is small ; the amount of caseinogen is about the same as in normal milk, or higher. The amount of globulin (probably combined with calcium) is from two to four times as much as that of caseinogen ; this globulin is not in solution but in suspension, and it coagulates at 15.28; S, 1.24; 0, 25-88. Serum-globulin contains C, 52.71 ; H, 7.01 ; Abnormal Milk. By R. GREIG SMITH (J. SOC. Chem. Ind., 1894, 13, 613--614).-Analyses are given of milk from two different cows, the cream of which could be converted into butter by simply stirring with a stick,without the use of a churn. I n both samples, the quantity of fat was slightly less than that calculated by Droop Richmond’s formula, although the butter produced had a normal composition.In the ash, there appeared to be a deficiency of potassium and an excess of calcium salts. The fat globules of both samples had an average diameter nearly double that of the globules of milk obtained from the Jersey cow, the maximum diameter being as great as 0.001 inch. The ab- normal properties of the milk are probably to be attributed to the size of the fat globules. Examination of Sheep’s Milk, with Special Regard to the East Friesland Breed. By HERMANN HUCHO (Bied. Centr., 1898, 27, 391-392; from Lundw. Jahrb., 1897, 26, 497).-Three East Friesland sheep, five, one, and two years old, gave about 205, 105, and 195 kilos. of milk in a year.

The colostrum was rich in fat (7-9 per cent.) and proteids. Although the three sheep were selected as patterns, the yield of milk was much less than t,be amounts often stated to be obtained. After lambing, the sheep only weighed 61.5-56 kilograms, and gave only 3.15--3-45 kilograms of wool, which, however, was not of bad quality.Merino, Hampshire, and two other varieties of sheep, the milk of Sp. gr. matter. 1-111 {620 ABSTRACTS OF CHEMTCAT, PAPERS,. which was examined, on a few days gave 40-80 kilos. of milk, reckoned on the whole period of lactation, containing 3.0-4-5 per cent. of fat. Uric Acid Crystals, By SCHREIBER ( V~VCIAOW~S A d i v . , 1898, 153, 147--151).-Ebstein stated that, after treating crystals of uric acid, or urinary gravel, with dilute alkali, the pigment is removed, and the remaining crystds retain their original form and power of double refraction. They give no proteid reaction. Moritz and Mendelssohn, on the other hand, allege that the crystals have a stroma or sub- stratum of proteid nature.The present research to reinvestigate the question, undertaken under Ebstein’s directions, confirms Moritz’s statement that, after dissolving out the uric acid with a solution of lysidine and tannic acid, a shadow ’ of the crystal remains behind, which is optically inactive. The same is true for uric acid crystals artificially crystal- lised from an albuminous liquid. After the uric acid is purified by repeated recrystallisations, this does not occur. The so-called ‘shadow,’ however, gave none of the proteid reactions. Physiological Action of Butyric and P-Hydroxybutyric Acids, By WILHELM STERNBERG ( V~VC~OW’S A d i u . , 1898, 152, 207-21 7). -Butyric acid injected intravenously in animals (cats) produces coma, but synthetically prepared P-hydroxybutyric acid does not produce this effect. This acid is optically inactive ; that found in diabetics is the optically active acid, This consideration, however, is believed not to militate against the conclusion drawn, namely, that diabetic coma is not due, as Minkowski considers, t o P-hydroxybutyric acid; the cause of the coma is stated to be a lessening of the alka- linity of the blood. By ADOLF BECK (P$iigev’s A~chiv., 1898, 71, 560--595).-The convulsions which follow the in- jection of urine into the circulation are not due to its action on the cerebral cortex, for they arise also in animals in which the hemi- spheres have been removed. They are probably a symptom of dyspncea, which is produced by disordered circulation in the bulb. The principal action of urine is on the heart, which is paralysed ; the effect on the respiration is secondary to this. The toxic agents in the urine are its potassium salts, not ptomaines, as Bouchard thought. The antagonism between the urine of the day and night on which Bouchard lays so much stress in his theory on sleep does not exist. The toxic action of both varieties of urine is the same. W. D. H.

VEGETABLE PHYSTOT,OCrY AND AGRlCTTT,TlTRE, 621 Chemistry of Vegetable Physiology and Agriculture. Progress of Fermentation Chemistry during the Last De- cades. By MAX DELBHUCK (Bey., 1898,31, 1913--1925).-An his- torical lecture, tracing the course which has been followed by the chemistry of fermentation during recent years. Alcoholic Fermentation without Yeast Cells. By HANS ABELES (Rer., 1898, 31, 2261-2267, Compare this vol., ii, 127,246, 346, and 396).--The author discusses the results of Buchner’s experi- ments on the action of antiseptics, and strong solutions of sugar and glycerol on yeast extract, and the apparent differences noticed in the case of living yeast cells. The amount of extract obtained from yeast, and the microscopic examination of the press cakes, indicate that not only the liquid por- tion, but also the protoplasmic contents of the cell are present in the expressed juice.The author accordingly compares the results of experiments on living yeast cells with those on yeast extract contain- ing the same percentage amount of cell-contents, and finds that the inhibiting action of sodium arsenite, chloroform, toluene, and ammo- nium fluoride is quite similar in both cases. Experiments made with strong solutions of cane-sugar and glycerol also indicate that, in mix- tures containing the same percentage amount of cell-contents, the effect of these agents on the activity of yeast extract is the same as that on emulsions of living yeast cells. The author, after discussing other arguments which are supposed to tell against the existence of living protoplasm in the extract, concludes that there is but little difference between the fermenting agents in the living cell and in the extract, and that the activity of the latter is best explained by assum- ing that it still contains living protoplasm.Production of Acid by Bacteria in Nutritive Media. By WILLIAM HANNA (J. Pathol. and Bacteyiol., 1898, 5, 367--273).-The production of acid is used to distinguish between Bacteyium coli and B. typhosus. I n milk, the acid doubtless originates from lactose; both the bacteria named above, however, produce acid. Acid prodnc- tion and curdling of the milk are not necessarily concomitants. In diluted serum to which carbohydrate is added, acid production may also occur. The amount of acidity may be determined by titration, and observations on a large number of micro-organisms are recorded.Of the carbohydrates used, lactose and dextrose appear t o he most readily acted on, with the formation of acid. Microbiology of the Process of Nitrification. By SERGEI WINOGRADSKY (Cent?.. Bcikt. Pay., 1896, 2, ii, 415-428, and 449-458). -Burri and Stutzer isolated a nitrate organism which showed rela- tively luxuriant growth on broth and gelatin, but at the same time lost its nitrifying power. The author’s experiments, made with a pure cultivation obtained from Burri and Btutzer, showed that, besides the M. 0. F. G. T. M. W. D. H.622 ABSTRACTS OF CHEMICAL PAPERS. nitrate organism, another, morphologically very similar, organism was present, which develops in organic solutions. The following conclusions are drawn.The oxidation of nitrites to nitrates must a t present be considered as a strictly specific function, incompatible with the property of decom- posing organic, especially highly nitrogenous, matter. This function is not labile, but is inseparable from the vitality of the microbe, the development of which is only possible in conjunction with the oxidation of nitrites. The divergent results of Burri and Stutzer arose from an experimental error, and a nitrate bacillus which thrives on gelatin is a t present unknown. Denitrification. By G. AMPOLA and C. ULPIANI (Gaxzetta, 1898, 28, i, 410--438).-The authors have succeeded in isolating two new denitrifying organisms ; one, Buct. denitrijicccns Y , is obtained from earth, and the other, B. denitrijicans VI, infects suitable media on exposure to the air.From the results obtained on cultivating these organisms and ex- amining the products of their action on the medium, the authors conclude that the process of denitrification can be expressed 'by the equation, 5C,H,,O, + 24KN0, = 24KHC0, + 6C0, + I8H2O + 12N,. N, H. J. M, W. J. P. The Nitrate Fungus. By ALBERT STUTZER and R. HARTLEB (Clmz. Centr., 1897, ii, 622-623 ; from Centr. Bakt. Par., 3, ii, 351-354)- About 89-93 per cent, of nitrogen as nitrites is converted into nitrate by the nitrate-bacteria ; carbonates, chlorides, and sulphates are favourable, but calcium chloride is unfavourable, to nitrification. Nitrates are not produced in presence of ammonium salts, but only after the whole of the ammonium salts within reach of the organisms have been converted into nitrites.The Principal Amide of the Sugar-cane. By EDMUND C. SHOREY (J. Amer. Chem. Soc., 1897, 19, 881--889).-It has Iong been known that in many plants a portion of the nitrogen present exists in the form of amides, the amount varying with the life and condition of the plant. Crystalline specimens of an amide, obtained from cane-juice by previous observers, have been assumed to be asparagine, but the author finds that the principal amide of the sugar-cane is optically in- active and is not asparagine, but glycocine ; the latter compound has not hitherto been known to occur in plants. Fifteen preparations of glycocine, made from samples of the cane during various stages of growth, indicate that this amido-acid is a normal constituent through- out the life of the plant.Glycocine is most easily distinguished from asparagine by the reaction with hot solutions of alkalis. Even with dilute alkali, asparagine readily evolves ammonia with the production of aspartic acid; glycocine, however, gives no ammonia unless the solution is strongly alkaline, and after the evolution of ammonia has ceased only hydrocyanic and oxalic acids are found in solution. Since the glycocine of sugar-cane has been mistaken for asparagine, it is possible that its presence may have been overlooked in other plants. Should it occur in the G?*ami.nce, which form the major portion N. H. J. M.VEGETABLE PHYSIO1,OGY AND AGRICULTURE. 623 of the food of herbivorous animals, this would help t o account for the relatively large quantity of hippnric acid found in the urine of these animals. Glycocine is probably the form in which nitrogen is conveyed t o the growing parts of the sugar-cane, and, as maturity is reached, i t is converted into proteids, which again furnish glycocine when a fresh growth takes place. There appears to be in the cane a gelatin, or gelatin-yielding proteid which gives glycocine as a product of decom- position.G. T. M. By EDMUND C. SHOREY (J. Arner. Chem. Soc., 1898, 20, 133--137).-The amido-substance present in the juice of the sugar-cane is glycocine, as with benzoic chloride it gives rise to hippuric acid, which was identified by its analysis, appearance, and solubility. The melting points of the amido-substance and the hippuric acid obtained from it are, however, not given.Lecithins of Sugar-cane, By EDMUND C. SHOREY (J. Amer. Chem. Soc., 1898,20, 113--118).-0n precipitating the proteids of raw cane- juice with cupric hydroxide and filtering, a solution is obtained which yields a chocolate coloured precipitate with sodium phosphot ungstate dissolved in dilute sulphuric acid ; on triturating the dried precipitate with powdered sodium carbonate, extracting with 95 per cent. alcohol, evaporating t o dryness, dissolving in water, and extracting with ether, a wax-like substance is obtained, which appears to be a mixture of several lecithins, On digesting it with barium hydroxide, and de- composing the salts formed with sulphuric acid, oleic acid is obtained, together with pnlmitic and stearic acids; betaine and choline were also isolated, but i t is not yet certain whether they existed free in the original juice, or were wholly produced by the hydrolysis of the leci- thins.It appears that phosphotungstic acid precipitates from cane- juice, together with the lecithins, a colouring matter, which contains no nitrogen, and is probably a glucoside. From the above work, it follows that the method generally adopted of designating as " amide-nitrogen " the difference between the total nitrogen of the juice and the " albuminoid " nitrogen present in the cupric hydroxide precipitate is one liable to considerable error ; a large proportion of the so-called amide-nitrogen is attributable to substances present of the type of the lecithins, By JULIUS STOKLASA (Zeit.phpioZ. Chem., 1898, 25, 398--405).-From analyses of lupins at flowering time, the conclusion is drawn that the formation of lecithin and proteids de- pends on photosynthetic assimilation, the chloroplasts working with the energy derived from the sun's rays. The chlorophyll-free cells of fungi form their proteid and lecithin molecules by other processes, concerning which a later communication is promised. By THOMAS B. OSBORNE and GEORGE F. CAMPBELL (J. Amer. Chem. S'oc., 1897, 19, 454-482).-Both yellow lupin (Lupinus Zuteus) and blue lupin (L. angustifoZius) seeds contain very little proteid matter soluble in water. In the case of yellow lupin, the amount is only some 0.37 per cent. ; a part of this consists The Sugar-cane Amide.W. A. D. W. A. D. Lecithin in Plants. W. D. H. Proteids of Lupin Seeds,624 ABSTRACTS OF CHEMICAT, PAPERS. of proteose, and the remainder is either albumin or a globulin readily solnble in very dilute saline solutions. Peptone is not con- tained in the freshly ground seed, but is formed in small quantity after prolonged contact with water. Yellow lupin seeds yield as much as 26.2 per cent. of proteid matter soluble in saline solutions; this is Ritthausen's conglutin. Preparations from blue lupin are usually much purer than those from the yellow, for the latter contain a con- siderable amount of some substance containing sulphur, from which conglutin can be separated by fractional precipitation out of dilute salt solutions. This explains why Ritthausen's conglutin from the yellow lupin contained twice as much sulphur as that from the blue lupin.When purified, no difference in properties and reactions can bc detected between preparations from the two seeds, The results of a number of analyses gives the following percentage composition. Con- glutin from yellow lupin, C = 50.91 ; H = 6.88 ; N = 17-93 ; S = 0.52 ; 0=23.76. Conglutinfrom bluelupin, C=51*13; H=6*86; N = 18.11; S = 0.32 ; 0 = 23.58. Conglutin is readily soluble in sodium chloride solutions containing upwards of 5 per cent. of the salt; on sufficient dilution, it is precipitated, a syrupy liquid separating which is rendered opaque and solid by treatment with water. When dissolved in salt solution, i t appears not to be affected by prolonged heating in a boiling water bath, but solutions thus heated, when allowed to cool, form a solid, opalescent jelly, which becomes clear and fluid on further heating.Unlike other globulins, conglutin does not yield insoluble (coagulated) products when washed with alcohol, or when dried. The lupin meal, which has been extracted with salt solution, yields a small quantity of proteid when exhausted with 0.2 per cent. potas- sium hydroxide solution. This proteid can be precipitated by adding acetic acid in slight excess, but not by making the solution neutral to litmus. Its percentage composition is, carbon = 5 1-40 ; hydrogen = 6-79 ; nitrogen = 16.43 ; sulphur = 1-03 ; and oxygen = 24.35 per cent. J. J. S. Proteids of the White Podded Adzuki Bean (Phaseolus radiatus). By THOMAS BURR OSBORNE and GEORGE F.CAMPBELL (J. Anzei.. C'lLenz. Xoc., 1897, 19, 509-5 1 3).--Pl~c~seoZzcs radiatus is a small, red bean, cultivated in Japan; its chief globulin is phaseolin, iden- tical with t h a t obtained from the white bean (Abstr., 1896, i, 454). A small quantity of another globulin is also present ; this can only be partly removed from i t s solutions by dialysis into water, but is wholly separated, in a coagulated form, by dialysis into alcohol. The same globulin has also been found in the pea, vetch, and cow pea. Its composition is, carbon = 53.97; hydrogen = 7-01 ; nitrogen = 16.31; sulphur = 0.88 ; and oxygen = 21.83 per cent. J. J. S. Proteids of the Pea. By THOMAS B. OSBORNE and GEORGE F. CAMPBELL (J. Amer. Chem. Xoc., 1898,20,348-362.Cornpare Abstr., 1896, i, 715).-It has been found that the legumin of the pea is always contaminated with more or less vicilin, a proteid first obtained from the horse-bean, Picia fkba. When the vicilin is completely removed, the differences previously noted between the legumin of theVEGETABLE PHYSIOLOGY AND AGRICULTURE. 625 pea and that of the vetch disappear, and preparations from these two seeds "are identical in composition and reactions, Legumin is not coagulated when its solutions are heated ; vicilin, on the other hand, becomes coagulated when its solutions are heated to 95-100' ; it is also soluble in a more dilute brine than legumin. Besides these two globulins, two other proteids are present in the pea, namely, proto- proteose, which is precipitated by the addition of acetic acid to a solu- tion saturated with salt, and deuteroproteose, which is not precipitated by acetic acid, The combined amount of legumin and vicilin obtained by dialysing extracts of the pea is about 10 per cent.J. J. S. Proteids of the Lentil. I;y THOMAS B. OSBORNE and GEORGE F. CAMPBELL (J. Arner. Chent. Soc., l898,20,362--375).-Coarsely ground lentils which had been freed from the outer seed coats by a current of air, were ground to fine flour, and the probeids extracted by a 10 per cent. solution of sodium chloride; the clarified and filtered extract being then subjected to fractional dialysis, and precipitation with ammonium sulphate. The products thus obtained were then subjected to careful fractional precipitation from dilute saline solutions, and by this means the same proteids as had been found in the pea (Abstr., 1896, i, 715, and preceding abstract) were obt,ained, namely, legumin, vicilin, legurnelin, and proteose. The amount of the globulins extracted by water is much greater in the case of the lentil than in that of the pea, especially if the acid of the seed is first neutralised by barium hydroxide.J. J. S. Proteids of the Horse-bean (Vicia faba). By THOMAS B. OSBORNE and GEORGE F. CAMPBELL (J. Amel.. Chem. Xoc., 1898, 20, 393-405. Compare Ritthausen, Abstr., 1883, 675 ; 1884, 1405).-In order to avoid contaminating the proteids with tannin, which Ritthausen found to be present in considerable quantity in the skin of the beans, the greater part of the outer coating was removed from the coarsely broken seeds by a current of air, and the remainder by hand picking.The subsequent treatment was the same as in the case of the lentil (preceding abstract). The proteids isolated were the same as in the case of the pea and lentil, namely, legumin, vicilin, legumelin, and proteose. The amount of these proteids extracted from the seed by water is about 16-18 per cent., the yield being slightly higher when the acid contained in the seed was neutralised with barium hydroxide before extraction ; the unneutralised extract, unlike the neutralised, and un- like other extracts of legumes, gave a heavy precipitate with pure sodium chloride. The addition of acetic acid gave a large precipitate soluble in dilute brine; so also did calcium chloride and calcium sulphate.J. J. S. Proteids of the Vetch. I;y TIIONAS B. USBORNE and GEOBGE P.

Vicilin, which occurs in the pea, horse- bean, and lentil, is not present in detectable quantity in the vetch. J. J. S. Proteids of the Pea, Lentil, Horse-bean, and Vetch. BY THOMAS B. OSBORNE and GEORGE F. CAMPBELL (J. Amel.. Chem. Soc., 1898, 20, 410-419. Compare Abstr., 1896, i, 715, and preceding abstracts).-The seeds of the pea, lentil, horse-bean, and vetch contain legumin, legumelin, and proteose; the pea, lentil, and horse-bean also contain vicilin.Full analytical numbers and descriptions of the pro- perties and reactions of these proteids are given. The authors think that legumelin is to be classed with the albumins rather than with the globulins ; the amount of legumelin present in the pea is 2 per cent., in the vetch 1.5, and in the lentil and horse-bean 1.25 per cent. J. J. S. Proteids of the Soy-bean-Glycine Hispida. By THOMAS B. OSBORNE and GEORGE F. CAMPBELL (J. Amev. Chem. Soc., 1898, 20, 41 9-428).-Two varieties of soy-bean have been examined, namely, yellow soy-bean and the variety known in Japan as Kiyusuki diadxu. The seeds were treated as in previous cases (preceding abstracts).The chief proteid is a globulin somewhat similar to legumin, but of different composition, containing nearly twice as much sulphur, 0.4 per cent. more carbon, and 0.5 per cent. less nitrogen. The authors term this proteid glycinin; its composition is : carbon = 52.12 ; hydrogen = 6-93 ; nitrogen = 17.53 ; sulphur = 0.79 ; and oxygen = 22.65 per cent. It is readily soluble in sodium chloride solutions, and is precipitated by dialysis, by dilution, or by cooling. Solutions containing more than 2 per cent, of sodium chloride dissolve glycinin freely, whilst the solvent power of those containing less salt diminishes more rapidly than the percentage of salt decreases. Dissolved in sodium chloride solution, the globulin is not precipitated by saturating with magnesium sulphate or sodium chloride, but is completely pre- cipitated by saturating with sodium sulphate a t 34".When prepared from carefully neutralised extracts, .glycinin is not soluble in pure water ; if soy-bean meal is treated with water, upwards of 16 per cent. of the globulin is dissolved, but here the solution is due to the potassium phosphates contained in the seed. Its solution in 10 per cent. sodium chloride is not coagulated by prolonged heating in a boiling water bath. Dilute acetic acid yields a precipitate which is insoluble in excess of sodium chloride solution. The insoluble, so-called albuminate, form of this globulin, like that of legumin, when treated with salt solution, becomes gelatinous, and it is impossible to filter solutions containing even a small quantity of it.I n absence of salts, glycinin is readily soluble in very dilute acetic acid, and is precipitated from such solution by sodium carbonate, even before the acid is com- pletely neutralised. The soy-bean contains a more soluble globulin, which is probably identical with phaseolin. It also contains about 1.5 per cent. of legumelin and a small quantity of proteose. J. J. S.VEGETABLE PHYSIOLOGY AND AGRICULTURE. 627 Proteids of the Sunflower Seed. By THOMAS B. OSBORNE and GEORGE F. CAMPBELL (J. Amer. Chem. Xoc., 1897, 19, 487-494, Compare Ritthausen, Abstr., 1880, 677 ; Vines, J. Physiol., 3, 93)- The meal of the seeds was freed from oil and then extracted with 10 per cent. sodium chloride solution; a quantity of proteid was obtained from this extract by dilution, by dialysis, and aIso by saturation with sodium chloride, I n composition and reactions, this proteid agrees with the globulin edestin, except that a part of it is precipitated by saturating its solutions in brine with sodium chloride ; in composition, the part precipitated by saturating with salt and that remaining in solution are alike.As obtained by extraction from the seed, it is probable that the globulin is mixed with some 2 or more per cent. of helianthotannic acid, from which it cannot be com- pletely separated, The authors cannot confirm Vine's statement that, if the seeds are treated with alcohol instead of ether, the globulin contained in them becomes soluble in concentrated salt solution. J. J. S. Proteids of the Cow Pea (Vigna Catjang).By THOMAS B. OSBORNE arid GEOXGE F. CAMPBELL (J. Amel'. Chem. Xoc., 1897, 19, 494-500j.-The chief proteid of the cow pea is a globulin which the authors term vignin; it much resembles the legumin of the pea and vetch, but differs in composition and properties. Its composition is : carbon = 52.64, hydrogen = 6.95, nitrogen = 17.25, sulphur = 0.5, and oxygen=22*66 per cent. It dissolves in cold or warm water free from dissolved salts, and may be precipitated from such solutions by the addition of a very little sodium chloride. It is readily soluble in saline solutions containing upwards of 5 per cent. of sodium chloride, but very little dissolves in a 1 per cent. solution. It is readily and completely soluble in dilute acids or alkalis in the absence of salts ; but solutions in very dilute nitric or hydrochloric acid are precipitated by salt or by excess of these acids.It is much less readily soluble in dilute sulphuric acid, and is not precipitated by an excess of the acid. Dissolved in 0.5 per cent. sodium carbonate solution, the proteid is precipitated by neutralisation. When dissolved in 10 per cent, sodium chloride solution, it is precipitated on the addition of a considerable quantity of hydrochloric or acetic acid ; the saline solution deposits the globulin on dilution more readily than do similar solutions of legrxmin ; saturation with sodium chloride does not precipitate vignin, but saturation with sodium sulphate at 34' causes complete precipita- tion. Solutions in 10 per cent. brine become turbid when heated to 98", and after continued heating set t o a jelly.I n addition to vignin, the cow pea contains a small quantity of a globulin, probably phaseolin, and a third globulin can also be extracted ; this is very readily soluble in very dilute salt solutions, and is partly precipitated by dialysis into water, and completely into alcohol. Its per- centage composition is : carbon = 53,25, hydrogen = 7-07, nitrogen = 16.36, sulphur = 1 *11, and oxygen = 22.21. J. J. 8. By EMILK FLEURENT (Compt. rend., 1898, 126, 1374--1377).-A specimen of bean flour was found to contain 31.011 per cent. of nitrogenous con- Proteids of Bean Flour and Wheaten Flour.628 ABSTRACTS OF CHEMICAL PAPERS. stituents, comprising legumin, 18-92 per cent. ; vegetable albumin, 0.20 per cent.; glutenin, 9.52 per cent. ; and gliadin, 2.40 per cent. The value of wheaten flour is closely connected witli the composition of the gluten, which should consist of glutenin and gliadin in the proportion of 1 to 3, and it is a common practice to improve certain varieties of wheaten flour by adding 2 or 3 per cent. of bean flour. The effect of this admixture is to maintain the proper ratio of glutenin to gliadin, bean flour being especially rich in glutenin, whilst wheaten flour is sometimes deficient in this substance. N. L. Decomposition of Proteids in Living Plants. By ERNST SCHULZE (Zeit. ph~sioZ. Chem., 1897, 24, 18-1 14).-During germina- tion, a mixture of nitrogenous compounds, in which aromatic and fatty amido-acids and arginine are probably invariably present, are produced in the decomposition of the proteids, and of the albumoses and peptones formed by the hydrolysis of the proteids.It may be questioned whether asparagine and giutamine are directly produced to any great extent, but this is by no means improbable. These products are to a great extent further decomposed, a portion of the nitrogenous residue (P ammonia) being utilised in the synthesis of asparagine and glutamine and possibly other compounds. The object of this process is to con- vert the products which are not suitable for producing- proteids into material available for this purpose. Whether similar changes take place in plants subsequent to germination remains t o be proved. A t the same time, there is no evidence against such a supposition.An examination of alcoholic extracts of etiolated lupin seedlings for amido-acids gave the following results. Seedlings of Lupinus angusti- folius (6 days) yielded mainly leucine. Eight-day old seedlings fur- nished about l per cent. of amido-acids containing, besides leucine, a certain amount of tyrosine, and probably a little phenylalanine. Seed- lings of Lupinus Zuteus (6 days) gave results similar, both qualitatively and quantitatively (as regards total yield), to 8-day old seedlings of L. ungustifolius, but they probably contained arginine as well. Estimation of Asparagine.-Finely ground seedlings, mixed with a little calcium carbonate, are extracted with hot water, and the filtrate evaporated to a thin syrup, being filtered a second time during the evaporation.The crystals of asparagine which separate after 1-2 days are washed with cold water and dilute alcohol, dried at 105' and weighed ; the mother liquor, &c., are evaporated to a syrup, and the crys- tals which separate placed on a porous plate, and afterwards crystal- lised from water. The whole of the crystals are weighed, the weight of the small amount of ash they contain being deducted. N. H. J. AT. Solution of the Reserve Substances of Grain and Bulbs. By KONSTANTIN A. PURIEWITSC~I (Awn. Agroit., 1898,24,288, from Ber. deut. bot. Ges,, 14).-When wheat and maize, from which the embryos and scutella have been removed, are kept in contact with distilled water (complete immersion being avoided), the reserve matter of the endo- sperm is dissolved out and the cells become empty as during ger- illination.When saline or organic solutions are employed instead ofVEGETABLE PHYSIOLOGY AND AGRICULTURE. 629 water, the emptying of the endosperm is greatly hindered, whilst it is completely stopped by treatment with ether or chloroform. Lupins, haricots, and bulbs from which the embryos were removed gave similar results. The embryo is, therefore, not essential for the solution of the reserve substances, although it does undoubtedly secrete diastases, which penetrate to the albumen and accelerate its digestion. Bulbs and cotyledons thus exhausted can be refilled by means of appropriate solixtions. This was observed in the case of AZZiuna cepu, which, after being kept 6 days in contact with a 5 per cent. solution of saccharose, was found t o contain a considerable amount of glucose.With the endosperm of wheat and maize, however, negative results were obtained. N. €3. J. M. Cascara Sagrada. By ALFBED R. L. DOHME and HERMANN ENOEL- HARDT (J. Amev. Chem. A%., 1898, 20,534-546).-The air-dried powder of CcGscara sagrada bark, af ter drying at 1 10' to constant weight, is shown to contain 8.3 per cent. of moisture. The ash (about 7 per cent.) con- tains sodium, potassium, aluminium with traces of calcium and iron, together with silicic acid and traces of hydrochloric and sulphuric acids, On extracting with chloroform in a specially devised apparatus, it gives 7.5 per cent. of a dark greenish-brown oil, a portion of which is volatile with steam. It has a yellowish-green colour and to a marked degree the characteristic odour of the bark.The residual oil contains neither alkaloid nor glucoside, but on saponi- fication with potassium hydroxide yields a substance crystallising in white leaflets melting at 24-26' and having the composition C,,H,,O. It is probably normal dodecyclic alcohol, which melts a t 24' and is present in combination with palmiti.: and stearic acids. The residue from the chloroform extract, when treated with alcohol, gives a glucoside crystallising from acetone and ethylic acetate in dark brown-red needles melting at 237'. The authors propose to call this substance puvshianin. On heating it with alcoholic hydrochloric acid, i t yields a sugar and euodin. A. W. C. Investigation of Soil for the purpose of J u d g i n g its Mechanical and Chemical Properties.By KURT BIELER (Juhd. ag&%.-chern. Versuchs. Stat.-Ralle n.-AS., 1896, 2, 146--155).-The soils examined were in part those of the experimental station itself, but mostly from elsewhere. In estimating lime and phosphoric acid, for instance, in samples which have not been subjected to mechanical analysis, the air-dried soil (250 grams) is heated for half an hour on a water bath with 500 C.C. of water, being frequently stirred. The whole is then removed to a 0.2 mm. sieve and washed through with a brush; it is afterwards washed through gauze, and the dust thus obtained analysed. The results are calculated on the weight of air-dried fine sand, the weight of which, as well as of the dust, must be ascertained.

Agron., 1898, 24, 130--134).-As bearing on the results of Schneidewind, who found that the pentosans present in straw may serve as food for denitrifying bacteria, an experiment is described in which the effect of adding starch and straw respectively to soil containing nitrates was observed.Whilst the addition of starch caused practically the whole of the nitrates to disappear, only about a third of the nitric nitrogen was lost under the influence of straw. The amount of straw was 1 per cent. of the weight of the soil, a quantity greatly in excess of the weights usually applied in practice. The injurious effect of great quantities of farmyard manure is perhaps due rather to nitrification being checked than to actual loss of nitrates. It is agreed that fresh farmyard ruanure,like straw itself,contains deni- trifying organisms, but inasmuch as their action is only evident when excessive amounts of manure are applied, it is unnecessary to incur the expense of treating stable-manure with sulphuric acid or super- phosphate, either t o prevent denitrification in the soil, or to prevent loss of nitrates in the manure itself, since nitrates do not seem to occur in farmyard manure.Application of acid to prevent loss of ammonia is, of course, quite another matter.

Compare Abstr., 1897, ii, 120).-Phosphoric acid (1 and 0.5 per cent.), in the form of superphosphate and basic slag respectively, was mixed with soil poor in phosphates, and extracted during 24 hours with water saturated with carbonic anhydride.The two manures behaved i n exactly the same way as in the previous ex- per imen t s. Alkali Chlorides in t h e Grapes and Wines of the Province of Oran. By EDMOND BONJEAN (Compt. qaend., 1898,128,1275-1277).- Twenty-eight samples of wine were collected by the author in different parts of the province of Oran, especially in the neighbourhood of the salt lakes, and only 3 were found t o contain less than 0.60 gram of chlorine per litre; 15 contained from 0.60 to 1.2 gram, and 10 contained more than 1.2 gram per litre. The maximum amount found was 4.5 gram per litre. There seems t o be no general law as N. H.J. M. N. H. J.

Agron., 1898,24,97--123). -Comparative experiments with different varieties OF roots showed that the French roots, probably owing to their greater leaf develop- ment, contain a greater percentage of dry matter than other varieties ; they also contain the most sugar and proteids. The relation between the dry matter and the density of the juice is nearly constant (dry matter + density = 2*S), so that the amount of dry matter, and hence the value of a crop, miiy be estimated by deter- mining the sp.gr. of the expressed juice. Roots which contain the lowest percentage of dry matter cont'ain the largest amount of potassium nitrate ; the French roots are poorest in nitrate, the German roots the richest, As regards the yield per acre, the German varieties gave the heaviest crops but the smallest amount of dry matter. As a rule, the yield of sugar and proteids follow the yield of dry matter. The relation (sugar + nitrogenous matter) -+ dry matter is highest in the French varieties. The relation nitric nitrogen + total nitrogen is very variable, from S to 17 in French to 35 and 40 in German roots. Six varieties of English roots held an intermediate position in value between the B'rench and German varieties.N. H. J. M. Sesame. By AUGUST HEBEBRAND (Landw.

HENRY (AWL AgTon., 1898, 24, 138-140 ; from Compt. rend. Soe. Xci. Nancy).-In agricaltural soils, there is loss of nitrogen, in the form of nitrates, through removal in crops and in drainage. In the case of forests, there is presumably no loss of nitrates in drainage, since Boussingault, Ebermayer, Brdal, and the author failed to detect &rates in forest soils. It is probable, however, that nitrification does take place in such soils, but that, as nitrates are produced, they are at once de- nitrified. The gain of nitrogen which is known to take place in forest soil is attributed, on the one hand, to fixation of free nitrogen by leguminous plants (broom, gorse, &c.), and, on the other, to fixation by dead leaves.It was found that when dead oak leaves were kept for a year in boxes exposed to air, the percentage of nitrogen in the dry matter rose from 1.108 t o 1.923. Taking into account that there mas a t the same time a loss of 21.62 per cent. of dry matter, the percentage of nitrogen a t the end of the year would have been 1.508, supposing the loss t o have been entirely due to decomposition of non-nitrogenous matter. On the assumption that 3300 kilos. of dead leaves fall on a hectare, there would be a gain of 22 kilos. of nitrogen. DEHERAIN calls attention to the results obtained by Kostycheff (Abstr., 1891,611), indicating that the gain of nitrogen is only relative, being due to disappearanceof carbonaceous matter.N. H. J. M. Results of Vegetation Experiments for ascertaining the Manurial Requirements of Soils. By MAX MAERCKER (Jahd. chgrik-chem. Versuchs-Stat. H ~ d h a.-S., 1896, 2, 169-1 73).--In order to ascertain by direct experiment what manures were wanted, white mustard was grown in the soil, in pots, without manure, with nitrogen and phosphoric acid, separately, together, and in conjunction with potash, and with potash and calcium carbonate. The following results, obtained with three samples of soil from a farm which hadVEGETABLE PHYSIOLOGY AND AGRICULTURE. 633 been much exhausted by the growth of fodder crops, are of interest, as giving clear indication of deficiency of phosphoric acid. The amounts of manure applied were : N, 3.0 ; P,O,, 1.5 ; CaO, 3.0 grams.The numbers indicate the amount of produce. N. N + P20J. N + CaO. N f P,Os -t- CaO. 1.

Making allowance for the fact that in pot experiments much greater crops and, in consequence, much greater differences in amounts of produce are obtained than in the field, it may be safely assumed that in the case of soils 1 and 2 an abundant application of phosphates would have a very decided effect. I n the case of soil No. 3, there was no indication of a deficiency of phosphates. Analyses of the three soils showed high percentages of phosphoric acid (0.230, 0.264, and 0*253), which, in the case of the first two, were not a t all in accordance with the results of the vegetation experiments.The fact that soil No. 3 contained only about the same amount of phosphoric acid a s 1 and 2, whilst, unlike these, it did not show a deficiency in the pot experiments, accords with the author’s observa- tion that the phosphoric acid of sandy soils is much more readily available than in loam or clay soils. Estimation of total phosphoric acid in soil is, therefore, of very limited value; whilst a low percentage indicates a deficiency, a high percentage is no conclusive evidence that available phosphoric acid is not deficient. At present, vegetation experiments cannot be dispensed with. N. H. J. M. * Loss of Ammonia in the Production. of Farmyard Manure.By PIERRE P. DEHPRAIN (Compt. vei~cl., 1898, 126, 1305--2310).-It has been shown by Berthelot and Andre that ammonium carbonate dissociates in aqueous solution, the escape of the ammonia being determined and regulated by that of the carbonic anhydride. These results are found to be applicable t o the loss of ammonia in the formation of manure, a loss amounting usually to one-third, sometimes to onehalf, of the total nitrogen contained in the excreta. Conditions favouring the escape into the atmosphere of the carbonic anhydride formed by the fermentation are accompanied by loss of ammonia, whilst when fermentation takes place in an atmosphere of carbonic anhydride, no loss of ammonia occurs. The author deduces from his observations the following practical rules.The soiled litter should be transferred to the dung-heap as frequently as possible, and the stable gutters flushed with water to carry the liquid excreta into a tank, which also receives the drainings of the dung-heap. The latter should be well heaped up and often wntered with the liquid from the t a n k ; an active fermentation is thus maintained, and the constant produc- tion of carbonic anhydride prevents the escape of ammonia. N. L,634 ABSTRACTS OF CHEMICAL PAPERS. Wiborgh Phosphate, a Manure prepared from Gellivnra Apatite. By LARS F. NILSON (Bied. Centr., 1898,2'7,385--390 ; from Ko,bgl. Zaiidtbruksakad. hundl. tzdski.., 1898, 1-1 '/).--The maguetite found a t Grangesberg and Gellivnra is, in part, mixed with considerable amoiints of apatite.To separate the two substances, the mineral is crushed until grains of about 1 mm. are obtained, and the iron com- pounds are then separated magnetically. The iron ore then contains about 71 per cent. of iron with very little phosphate, and is very suitable for the Martin process. The refuse contains abmt 80 per cent. of apatite, the rest being mainly felspar, with some quartz, mica and non-magnetic ferric oxides. As, at the present time, there is little .prospect of this substance being utilised as basic slag, a process, suitable for all crude phosphates, has been proposed by Professor Wiborgh for converting i t into manure, which consists in heating the product with sodium carbonate at about 900-1000°. A sample of Wiborgh phosphate thus prepared contained: K20, 1.54 ; Na,O, 14.69 ; CaO, 38.12 ; MgO, 2.88 ; Fe203 and A1203, 4.50; P,O,, 27.01; SiO,, 9.99 ; SO,, 0-27; F and loss on ignition, 1-00 per cent.It dissolves completely in hydrochloric acid, but only very slightly in water. The citrate-solubility of the phosphoric acid is readily brought up to 95 per cent. I n preparing the phosphate, the best results are obtained with 30 parts of sodium carbonate to 100 parts of apatite, when the latter contains 17 per cent. of felspar. Without felspar, the apatite is much less readily attacked and the product contains much less citrate-soluble phosphoric acid. A number of pot experiments were made with oats, peas, and sugar beet, in which different amounts of the new phosphate were compmed with corresponding amounts of citrate-soluble phosphoric acid in the form of basic slag and snperphosphate respectively.I n the case of oats, Wiborgh phosphate and basic slag were about equal, and better than superphosphnte. With peas, all three phosphates gave about the same amount of grain, but basic slag produced the most straw. As regards sugar beet, the percentage of sugar in the roots was about the same with Wiborgh phosphate as with basic slag, when large amounts were applied. N. H. J. M. Decomposition of Milk-Fat during the Ripening of Cheese. By H. WEIGMANN and A. BACKE (Landto. VeysuclwStat., 1898, 51, 1--14).-Previous results obtained by Henzold and Weigmann showed that, in the ripening of cheese, the greater portion of the milk fat remains unchanged, whilst according to Weidmann (Abstr., 1882, 692) the fat is either not altered a t all or only very slightly (compare also Msnetti and MUSSO, Lundw. Versuchs-Stut., 1878,21,218). Duclaux concluded that the fat undergoes only a slight change a t first, but that subsequently the change is very gredt, and that whilst at first the change is limited to the glycerides of the soluble fatty acids, the oleic acid glyceride is afterwards attacked (Principes de Zaiteke). The examination of a number of different kinds of cheese showed that, in the process of ripening, a portion of the fat is decomposed. I n cheeses of ordinary ripeness, 1-7 per cent. of the fat consists of non-ANALYTICAL CHEMISTRY. 635 volatile fatty acids. Of the hard cheeses, the newest (28 months) contained the smallest amount of fatty acids, whilst a soft cheese (3 months) was found t o contain nearly 7 per cent., indicating t h a t the decomposition dBpends more on the intensity of the ripening than on the age. There is also an indication that even after 24 months the decomposition may extend t o the glycerides of the non-volatile fatty acids. The cheese, mixed with sand, was extracted with ether, the dry extract purified by dissolving in light petroleum, and again dried at 100' to 105'. The free fatty acids were obtained by exactly neutralising the light petroleum ex- tract, dissolved in ether and alcohol, with N/10 caustic soda, after titrating a portion in order to ascertain the amount of alkali required. Any unchanged fat was then removed by extracting with light petrol- eum as long as anything dissolved; finally, the alcohol was eva.po- rated, the residue treated with dilute sulphuric acid, and the liquid fatty acids removed from the surface. The acids were weighed, the melting point determined, and in some cases they were titrated with caustic soda. The following is the method employed. N. H. J. M.

ANALYTICAL CHEMISTRY. 635 An a1 y tical Chemistry. Volumetric Analysis: Correction to be applied when an Aliquot Part of a Filtrate is Titrated. By Ruoss (Zeit. anal. i’hem., 1898,3’7, 422--426).-1n cases where a substance is estimated by adding a known excess of a precipitant, making up to a known volume, filtering through a dry filter, and titrating the excess of pre- cipitant in a portion of the filtrate, the error ( X - x) arising from arx neglecting the volume of the precipitate amounts to 1000 sm - ar’ where X is the true amount of the precipitate obtained, x = a(C - r), the amount calculated without applying the correction, _ _ - s=sp. gr. of precipitate, m, volume to equivalent of precipitate equivalent of precipitant’ a = whic6 the mixture is made up, C , the amount of precipitant used, and v , the excess found, calculated on the total volume m.Since, however, ar is small compared with 1000 sm, it may be omitted from the denominator without appreciable error, and x+- is the cor- rected result. By making m = 50 c.c., and using 25 C.C. of filtrate for titration, any error in this operation is only multiplied by 2, and by keeping the excess of the precipitant small, the correction often amounts to only a few tenths of a milligram. Spectrum Analysis of Minerals. By ARNAUD DE GRAMONT (Compt. rend., 1898, 126, 1513--1515).-The author has applied to a large number of compounds his method of allowing a condensed spark avx 1000 sm M. J. S.636 ABSTRACTS OF CHEMICAL PAPERS. to impinge on a bead of a mineral or precipitate pyeviously powdered and fused with sodium carbonate.Lithium is very readily recognised by meansof the red line 6708 and the orange line 6104. Sodium is recognised by the red doublet and the less refrangible green doublet, but potassium is difficult t o recognise, the green group K, and the violet line 4046 being the most distinct. Rubidium is easily recognised by means of the violet lines 4216 and 4202, and czesium by its blue lines 4593 and 4556. Barium, calcium, and strontium are particularly easily detected by this method ; the first by the red and orange lines 649'7 and 6142, the green 5778, 5536, and 4934, and the blue 4554; the second by the blue lines 4455, 4435, 4426, and especially by the violet 4227 as well as the ultra-violet 3969 and 3934 ; the last by the blue line 4608, the indigo 4306, and the violet 4216.Magnesium under these conditions is characterised by the green triplet Mg,, beryllium by the blue h e 4573, the reaction being less sensitive than with magnesium, mangan- ese by the group of five blue lines Mna, chromium by the green triplet 5209, 5206, and 5205. lron and nickel should not be sought for by this method. Aluminium, however, is readily detected by means of the red doublet 6245, 6235, provided that lithium carbonate is used instead of sodium carbonate. Vanadium shows the strong indigo lines, especially 4408, and zirconium shows five lines in the blue between 4816 and 4690, the line 4740 being the strongest and most persistent. The author gives the results of the examination of a large number of minerals by this method.Sterelectrolysis of Minerals. By FRANGOIS MAYENCON (C.R. Assoc. 1T;yanE. Adv. S'ci., 1898 [1897], 26, [ii], 347-348).-The name sterelectrolysis is given to the following method of analysing minerals. The fine powder is made into a paste with water, placed between two pieces of filter paper, and electroiysed between platinum electrodes with six dicliromate cells. Metals or their oxides appear a t the cathode, and acid radicles at the anode. For example, with galena, metallic lead and sulphuric acid are obtained, and with barytes, baryta and sulphoric acid. The separated constituents are then identified by ordinary analysis. L. J. S. By HEINRICH FRESENIUS, and H. BAYERLEIN (Zeit. anal. Chem., 1898,37,501--504). -The authors describe their metbod of carrying out Behren's test (this vol., ii, 482), and claim that as small a proportion as 0.2 per cent.of perchlorate can be directly detected, thus avoiding the somewhat troublesome concentration by means of alcohol recommended by Breukeleveen. Four to six drops of a concentrated, filtered solu- tion of the substance are placed on a microscopic slide, a few crystals of rubidium chloride are added, and the solution is coloured distinctly pink with permanganate. It is then evaporated over a small flame until a crystalline crust about 4 mm. broad forms round the edge of the liquid, when it is transferred to the stage of a microscope with a magnifying power of 150. Should the proportion of perchlorate be very small, further evaporation will be necessary C.H. B.

The paper is M. J. S. Detection of Bromine in Urine. By ADOLF JOLLES (Zeit. anal. Cheni., 1898, 37, 439-440).--The urine (10 c.c.) is mixed with sulphuric acid and excess of permanganate in a narrow-necked flask. A piece of filter paper soaked in a 0.1 per cent. solution of para- dimethylphenylenediamine is placed in the neck, and the flask is warmed on the water bath. If bromine is present, the paper acquires a violet colour, passing a t the edges through blue into grey and brown. As little as 0.1 milligram is easily detected. Neither chlorine nor iodine (unless in enormous excess) interferes with the reaction.M. J. S. Special Cases of the Estimation of Sulphur and of Iodine. By ANTONIO LONGI and L. BONAVIA (Gaxxetta, 1898, 28, i, 336-341). -The authors propose the following methods for estimating, in the same solution, sulphur, in the form of sulphites, thiosulphates, trithionates, tetrathionates, sulphides or polysulphides, and iodine, in the form of iodide or iodate. A. The solution containing sulphur and iodine is made alkaline with potassium carbonate, oxidised with potassium permangnnate (the excess of the latter being destroyed by alcohol) acidified with acetic acid, and filtered ; one proportional part of the filtrate is precipitated with barium chloride and the barium sulphate weighed, whilst another is treated with potassium iodide and the iodine titrated with thio- sulphate, after acidification with hydrochloric acid.If the solution contains no chlorides, it is treated, after oxidation and filtration, with nitric acid free from nitrous acid at 50-60°, and precipitated with barium nitrate; after filtering off the barium sulphate, the iodine is determined in the filtrate as before. B. The solution of sulphur and iodine compounds is oxidised with sodium peroxide, the excess of the latter decomposed, and the iodic acid reduced with zinc dust ; the filtrate may be treated in two ways. a. It is acidified with acetic acid, precipitated with barium acetate, and the barium sulphate filtered off after several hours repose a t 40' ; the iodine is precipitated in the filtrate with silver nitrate.6. It is neutralised with nitric acid, precipitated with silver nitrate, and strongly acidified with nitric acid ; the filtrate from the silver iodide is precipitated with barium nitrate. The several methods described all gave satisfactory test results. Separation of Dithionic Acid from the other Acids of Sulphur. By ANTONIO LONGI and 1;. BONAVIA (Gacxxetta, 1898, 28, i, 341-344).--Salts of sulphur acids of a lower degree of oxidation than sulphuric acid are, with the exception of dithionic acid, oxidised to sulphuric acid in alkaline solution by potassinm permangannte or hypobromite ; after the oxidation, the solution is precipitated with barium acetate, and the barium sulphate filtered off and weighed.

By EDWARD KELLER (J. Anzev. C'hem. SOC., 1897, 19, 771-778).-The precipitation of selenium and tellu- rium from solutions of the corresponding selenous and tellurous acids by sulphurous anhydride is only complete in the presence of hydrochloric acid. Selenium appears to be completely precipitated only when the solution contains 30 per cent. or more of strong hydro- chloric acid of sp. gr. = 1.175, whereas tellurium is completely thrown down from solutions containing 10 per cent. of this acid, but is not completely removed when the percentage of this acid present rises above 60.The two elements are both precipitated when a ferric salt is added to solutions of selenoua and tellurous acids and the iron precipitated with ammonia, but precipitation is only complete when a considerable excess of iron is present. Selenium may be separated from tellurium by means of ferrous sulphate, which reduces selenous acid completely in acid solution, but has no action on tellurous acid. Selenium cannot be separated from copper by treatment of the mixed sulphides of these elements with sodium sulphide, since the residue left invariably contains some sele- nium. Quantitative experiments lend some probability to the idea t h a t this precipitate contains copper selenide formed by the action of selenium sulphide on cupric chloride in the presence of hydrogen sulphide, which simply acts as a reducing agent : 3CuC12 + SeS, + 3H,S = 2CuS + CuSe + 6HC1+ 35.The test analyses are very satisfactory. Selenium and Tellurium. W. J. P. A. H. Modified Form of Nitrometer for Use in Nitrogen Estima- t i o n s by the Absolute Method. By HOOPER A. D. JOWETT and FRANCIS H. CARR (Chem. News, 1898, '78, 97).-In this nitrometer the two limbs arc continuous below, as in the Schwarz apparatus, but with a three-way cock between them, which can put the measuring tube in connection either with a nozzle or with the pressure tube; the latter when taking readings, the former during a combustion, so that the unabsorbed gas expels potash by the nozzle, which then dips under potash in a dish.The measuring tube is fitted with a side tube for admitting gas at the lower end, and with a two-way cock above for connecting with an outlet for the withdrawal of gas for analysis, or with a funnel for the admission of potash, a gentle stream of which is allowed t o flow through the apparatus during a combustion. By E. BOHLIG (Zed. anal. Chenz., 1898, 37, 498--501).-The proposed method is very suit- able for the estimation of nitrates in natural waters. The dry residue from 100 C.C. of the water evaporated in a conical flask, is treated with a few C.C. of concentrated sulphuric acid, and the neck of the flask immediately closed by a caoutchouc stopper, through which pass two short glass tubes of equal length. The other ends of these tubes D.A. L. New Method of Estimating Nitric Acid.ANALYTICAL CHEMISTRY, 639 are similarly fitted into another caoutchouc stopper, which is pushed loosely into the neck of a second conical flask containing a known excess of potassium ferrocyanide in 80-100 C.C. of water, the position of the two flmks being horizontal. The sulphuric acid is then caused t o moisten the whole of the water-residue, and as soon as evolution of gas ceases, the stopper is tightened in the neck of the second flask, and the apparatus placed vertically. The liberated nitric and hydro- chloric acids (the presence of a sufficient amount of chloride being presupposed or provided for) react with the ferrocyanide thus, 2HN0, + 6HCl+ 6K,FeCg, = 3K6Fe,CyI2 + 4H,O + 6KC1+ N,O,. The contents of the flasks are thorougbly mixed by repeatedly inverting the appa- ratus, so as t o allow the liquid in the upper flask to run into the lower one, and when the free chlorine is completely absorbed, the unoxidised ferrocyanide is titrated by permmganate. The organic matter usually present in a water.residue reduces permangnnate so much more slowly than does hydroferrocyanic acid t h a t it does not interfere with the recognition of the end point.

A 7 ox. wide-mouthed stoppered bottle is nearly filled with copper-zinc prepared in the usual manner, and 100 C.C. of the water to be analysed added ; the stopper is then inserted, and the mixture left at 20-25' during 48 hours; after thoroughly shaking the bottle, 50 C.C. of its contents is withdrawn, 200 C.C. of water Free from ammonia is added, and the mixture distilled wit11 sodium carbonate according to the ordinary met hod.Extraction uppc6ratus.--In this apparatus, the substance t o be exhausted is contained in a tube surrounded by the vapours of the boiling solvent ; the latter thus acts a t its boiling temperature, and consequently, very economical results are obtained. Estimation of Phosphoric Acid in Superphosphates. By L ~ o VIGSON (Compt. revzd., 1898, 126, 1522--1523).-1n the analysis of superphosphates, it is customary t o estimate separately and directly the quantities of phosphoric acid soluble in water and ammonium citrate solution respsctively. The author finds, however, t h a t when the quantity of phosphoric acid soluble in the citrate solution is small, the results are almost invariably too low, even when the precipitation is allowed t o go on for several hours.I f , however, the aqueous solution and the ammonium citrate solution are mixed, the estimation of the total phosphoric acid i n them is accurate. It is therefore recommended to estimate separately t h e phosphoric acid soluble in M. J. S. Laboratory Notes. W. A.

Analysis of Bone Superphosphate. By F. POQUILLON (Chem. A'exs, 1898, '78, 3--4).-The usual determinations of the soluble phosphoric acid and the nitrogen are not considered adequate for ascertaining whether the sample is an admixture of ordinary super- phosphate and nitrogenous matter, or a genuine bone superphosphate.It is suggested that the amount of Fatty matter soluble in carbon bi- sulphide or in benzene should also be estimated, inasmuch as the proportional relation of that factor to the phosphoric acid is practically constant in bone superphosphates, being 10 to 12 of fat to 100 of phosphoric acid in superphosphates from green bones or degelatinised bones, with fat previously removed by water, and 6.5 to 100 in super- phosphates from bones from which the fat has been extracted by benzene, proportions that cannot conveniently be obtsined by admixture with ordinary superphosphate when the nitrogen is also taken into consideration. Estimation of Boric Acid. By CLEMENTE MONTEMARTINT (Gaxzetta, 1898,28, i, 344-348).-The author has shown (Real.Accad. Linc., 1889, [iv], S), that Gooch's method (Abstr., 1887, 299) is the best for the estimation of boric acid; ThaddQeff (Abstr., 1897, ii, 597) does not quote this paper, and gives a method for determining boric acid which is inconvenient and complicated. Gooch's method is the only direct and convenient one for determining boric acid. Action of Carbonic Anhydride on Soluble Borates. By Lours C. JONES (Amer. J. Xci., 1898, 5,442-446).-Morse and Burton have worked out a process for estimating boric acid based upon the assumption that when a solution of this acid, mixed with excess of barium hydroxide is treated with carbonic anhydride, the excess of barium only is precipi tated as carbonate.The author, having made several experiments, finds the process quite untrustworthy, as the barium borate is also partially decomposed. Carbonic anhydride is capable of entirely displacing the boric acid, even from borax, if the acid is removed as fast as it is liberated. If a borate is boiled with methylic alcohol in a suitable apparatus through which a current of carbonic anhydride is being passed, the residue will, after some time, give no reaction for boric acid, the whole of it Detection and Estimation of Carbonic Oxide in Air in presence of traces of Gaseous Hydrocarbons. By ARMAND GAUTIER (Co~npt. rend., 1898, 126, 1299-1305. Compare this vol., ii, 535-538).-The air, previously filtered through glass wool and freed from carbonic anhydride and aqueous vapour by means of caustic potash, barium hydroxide, and phosphoric anhydride, is passed successively through two tubes heated in an air bath at 100-105°, and containing respectively iodic anhydride and finely divided metallic copper.The carbonic oxide is oxidised by the iodic anhydride with liberation of iodine, the latter being completely absorbed by the C.

Each milligram of iodine corresponds with 0.441 C.C. of carbonic oxide. I n the presence of hydrocarbons of the ethylene and acetylene series, which also reduce iodic anhydride to some extent, the air, after passing over the heated copper, is passed through weighed tubes of phosphoric anhydride and barium hydroxide to absorb the water and carbonic anhydride formed by the oxidation of the carbonic oxide and hydrocarbons.The tube containing iodic anhydride is also weighed before and after the experiment. The loss in weight of the latter, less the iodine absorbed by the copper, gives the oxygen supplied by the iodic anhydride, and the difference between this and the amount of oxygen corresponding with the water and carbonic anhydride produced, gives the weight of oxygen contained in the carbonic oxide Sources of Inaccuracy in the Estimation of Carbonic An- hydride and Aqueous Vapour in Large Volumes of Air. By ARMAND GAUTIER (Conzpt. Tend., 1898,126,1387-1393).-The author's researches on the estimation of minute quantities of carbonic oxide and hydrocarbons in the atmosphere (this vol., ii, 536) have led him to reconsider the question of the preliminary purification of the air from carbonic anhydride and aqueous vapour, and the relative e6ci- ency of caustic potash, barium hydroxide, sulphuric acid, and phos- phoric anhydride is discussed in detail.Even after the most careful purification by means of caustic potash, air still retains carbonic anhydride to the extent of about 0.1 C.C. per 100 litres, but this is easily removed by passing the gas through baryta water, or through a tube containing crystals of barium hydroxide slightly moistened with water. Experiment shows that the traces of carbonic anhydride which escape the action of caustic potash are not t o be attributed t o oxidation of the rubber connections of the apparatus, or t o diffusion, through the latter, of the external air.The removal of aqueous vapour may be effected, with sufficient accuracy for most purposes, by means of sulphuric acid ; 100 litres of air, carefully dried by this reagent, were found to retain only 0.3 to 0.353 milligram of water, as estimated by absorption by phosphoric anhydride. Since, however, sulphuric acid dissolves carbonic anhydride and other gases, i t is preferable, in the most exact analyses, to use phosphoric anhydride. Experiments were made with a view of ascer- taining whether the volatility of sulphuric acid is an appreciable source of inaccuracy. One hundred and ninety-two litres of air, after being dried with sulphuric acid, and subsequently filtered through glass wool, produced no sensible turbidity in baryta water, but the latter, on evaporating w i t h hydrochloric acid and taking up the residue with water, left 0.1 milligram of barium sulphate, corresponding to 0*00022 milligram of sulphuric acid per litre of air, a quite insignifi- cant proportion. It is calculated, from this result, that the vapour pressure of sulphuric acid a t 13-14' does not exceed one twenty- Table for Calculating Potassium Platinochloride into Po- tassium Oxide.By G~LTSCHKE (Zed. anal.

By MAX PASSON (Zeit. angzu. Chew?,., 1892, 776-77’i).-The advantage of this process is that i t may be used in the presence of iron, alumina, magnesia, and phosphoric acid without their previous removal. The sample is boiled with dilute nitro-hydrochloric acid in a half-litre flask until everything but the sand is dissolved. When cold, the liquid is made up to the mark, and an aliquot part is slightly over-neutralised with dilute ammonia, using phenolphthalein as indicator; a 10 per cent. solution of citric acid is then added until the precipitate has completely redissolved, and after that another 10 C.C. of the citric acid solution.The liquid, diluted to about 200 c.c., is heated to boiling, precipitated with ammonium oxalate, and the precipitate, which is crystalline, is collected, washed, ignited, and weighed as calcium oxide. The test analyses show the great accuracy of the process. L. DE K. Cyanometric Estimation of some Metals. By HARRY BREARLEY and HORACE JERVIS (Chem. News, 1878, 78, 177-179, 190-191. Compare this vol., ii, 258).-In adopting this method, to ensure uni- formity, either direct titration, or adding excess of cyanide and titrating back with silver nitrate should be exclusively adopted, more- over, the quantity of potassium iodide present affects the changes, and should be regulated; 2 C.C. of a 2 per cent. solution for each 500 C.C. of solution titratsd gives the deepest desirable cloudiness.Nickel andcopper present contrasts in their behaviour in this process; nitrates, acetates, tartrates, and sulphates in alkaline solution inter- fere in the case of copper, but not in that of nickel; with the latter metal, too, the reaction is complete with the theoretical quantity of cyanide, whilst with the former metal a great excess is required. I n titrating nickel, an error may arise by the formation of a silky, crys- talline compound, which is, however, prevented by the use of ammo- nium sulphate. Various experiments show that chromic oxide, aluminium, zinc, and iron interfere to a noticeable extent with the estimation of nickel by this method, zinc raising, the others lowering, the result, whereas calcium, barium, strontium, magnesium, cadmium, manganese, chromic acid, tin, molybdenum, arsenic, antimony, bismuth, lead, uranium, and tungsten do not interfere. This is true when the amount of nickel is 0.1 gram, the amount of interfering metal 0.05 and 0.1 gram, and the excess of ammonia 10 C.C.of 2N solution, the foreign element being generally added as chloride, and ammonium chloride replacing the sulphate where insoluble sulphates would be formed. The interference of zinc decreases with increased excess of ammonia, and may be obviated by adding the cyanide to a faintly acid or neutral solution, and using sodium carbonate instead of ammonia; then filtering, adding silver nitrate to the filtrate until only traces of free potassium cyanide remain, then repassing through thesame filter and completing the filtration ; if cadmium is present in quantity sufficient to interfere, the same method should be used.Whilst recognising theANALYTICAL CHEMISTRY. 643 utility of sodium pyrophosphate as a corrective in the case of zinc, the authors consider that the benefit observed is due to the low results arising from this corrective compensating the high result due to the zinc (Moore, Abstr., 1889, 1033) and, as Moore found with iron, the authors find with aluminium, that sodium pyrophosphate is not a good reagent to use for preventing precipitation ; it is, however, useful for the purpose in the case of copper titrations. Tartaric acid may be used to keep aluminium in solution, 0.1 gram of this metal requiring 1 gram of the acid, a large quantity of which, however, delays the reaction.I n the presence of aluminium, the titration G f nickel may be accurately effected by proceeding as in the presence of zinc, but adding the usual excess of ammonia, and not sodium car- bonate, filtering an aliquot portion of the liquid, and going back with silver nitrate ; a preliminary quantitative test, or some knowledge of the amount of nickel present, is necessary. I n the cast) of iron, the lorn result is due to mechanical retention of the nickel by the precipitate, and is overcome by adding the cyanide before rendering the solution alkaline, or by using an alkali carbonate instead of ammonia for precipitation. If any interference is anticipated on account of man- ganese, the treatment as in the case of zinc may be followed, using ammonium carbonate, or ammonium chloride may be used to keep the manganese in solution, but, as a matter of fact, the precipitstsd man- ganese hydroxides are harmless.I n the presence of chrornizcm, the direct titration of nickel is inadmissible; but with a knowledge of the approximate amount of nickel present, adding excess of cyanide, allow- ing some time to elapse and then titrating back, i t yields fairly accurate results; better still, the excess of cyanide may be added before making the solution alkaline. The mixed solution of chrom- ium and nickel salts, when neutralised, changes from greenish- blue to full green, the blue is restored by a drop of hydrochloric acid and the titration proceeded with; sometimes a precipitate forms before all the cyanide is added, if small it does not interfere.Chromic oxide salts may be rendered harmless by transforming them into chromatep, and using ammonium sulphate to retain any basic nickel chromate in solut,ion. Tin should be in the stannic form. I n the presence of sodium molybdate, the titration should not be delayed, inas- much as a nickel molybdenum precipitate forms very slowly; its forma- tion may be further retarded by using ammonium sulphate. For similar reasons, the titration should not be delayed in the presence of arsenic ; sodium arsenite lowers the results, but only by less than 1 per cent.; with the arsenate, however, the results are accurate. Antimony and bismuth oxychlorides do not interfere, but their precipitation may be prevented by means of a small amount of tartaric acid.Lead acetate does not interfere, and precipitation may be avoided by using nitrates instead of sulphates to heighten the iodine turbidity. Uyaniunt forms a pre- cipitate with ammonia, so that the carbonate should be used. Citric acid causes low results, and cannot be used to replace tartiric acid. It is noted that adding the cyanide to the slightly acid solution does not occasion any serious loss ; moreover, experiments indicate that the interference in the cases of chromium, aluminium, and iron appears to be due to mechanical retention. The case of manganese and copper is to be investigated. D. A. L.644 ABSTRACTS OF CHEMICAL PAPERS, Volumetric Estimation of Lead, Copper, Iron, Potassium Ferrocyanide, Dextrose, and Sulphuric Acid (in Sulphates). By RUOSS (Zeit.and. Chenz., 1898, 37, 426-436).-The operations are best performed in test-tubes of about 120 C.C. capacity. The lead to be estimated is thrown down as sulphate, or ferrocyanide, by an excess of sodium sulphate or potassium ferrocyanide. After boiling and cooling, phenolphthalein is added, and the liquid is accurately neutralised in the cold, It is then heated to boiling, and standard barium hydroxide solution is run in from a burette until the red colour of the upper liquor does not disappear on boiling and is not increased in intensity by further additions. The red colour becomes permanent when half of the lead salt is converted into oxide, but i t is better to add a few C.C. in excess and titrate back with N/5 acid, Conversely, sulphates and ferrocyanides are estimated by precipitating with lead nitrate and titrating the precipitate with baryta as above, after filter- ing and washing, if any metals precipitable by baryta are present.Chromic acid may be estimated by precipitating with an excess of lead and titrating the lead in an aliquot parl of the filtrate, correcting if necessary for the volume of the lead chromate (see this vol., ii, 635). For the estimation of copper, sodium oxalate is added until the copper oxalate first precipitated is redissolved, and then phenolphthalein and baryta. As soon as the free acid is neutralised, the solution acquires the colour of methyl-violet 6B. By adding calcium chloride, the double oxalate is decomposed, and now the red colour of the indicator does not appear until the copper is precipitated.A small excess of bargta is employed as in the case of lead, and the excess of alkali is titrated back with acid, but in this instance a t the boiling point. Small quantities of copper can be estimated by precipitating as ferro- cyanide, and titrating with baryta; the red colour appears when half the copper ferrocyanide is converted into oxide. The subsidence of all the ferrocyanide precipitates is greatly promoted by adding solid potas- sium nitrate and boiling. A modification of the above method serves well for ascertaining the amount of cuprous oxide obtained in a sugar estimation. After proceeding as prescribed by Allihn, but with the sugar solution diluted 2+-fold, the precipitate with its filter is thrown into a test-tube, dissolved in the smallest possible quantity of nitric acid, and the solution boiled for 3 minutes. Soda solution (free from carbonate) is then added until (with phenolphthalein) there is a decided excess of alkali, which excess is then exactly removed by dilute sul- To the still hot solution, 15 C.C.of N/25 sulphuric acid ghadded, together with methyl-orange, and after cooling, the excess of free acid is measured with N/5 soda.

M. J. S.Separations of Aluminium [from other Metals] by Hydro- chloric Acid. By FRANKE S. HAVENS (Amer. J. Sci., 1898,6,45-48). -The author (Abstr., 1897,ii, 232) has published a very good processANALYTICAL CHEMISTRY. 645 for separating aluminium from iron and beryllium, based on the fact that its chloride is insoluble in a mixture of hydrochloric acid with its own volume of ether previously saturated with hydrogen chloride. H e now states t h a t this process works equally well with mixtures of chloride of aluminium with chlorides of zinc, copper, mercury, and bismuth. L. DE K. Condition of Oxidation of Manganese Precipitated by the Chlorate Process. By FRANK A . GOOCH and MARTHA AUSTIN (Amer. J. Sci., 1898, [iv], 5, 260-268).-The authors’ experiments show that if due attention be paid to details, the precipitation of manganese nitrate by sodium chlorate in presence of concentrated nitric acid is practically complete, the manganese escaping precipitation being found in no case to exceed 0.0001 gram.The use of sodium chlorate is to be preferred to that of the potassium salt, since the latter, owing to its sparing solubility, is apt to be mechanically carried down with the precipitated oxide ; sodium chlorate also has the advantage of being more easily decomposed. The ‘‘ oxygen value ” of the precipitated oxide is best determined by dissolving it in sulphuric acid and potas- sium iodide solution, and titrating the liberated iodine with standard sodium thiosulphate solution; or by reducing the oxide with N/10 arsenious acid solution in presence of sulphuric acid, neutralieing the solution with potassium hydrogen carbonate, and titrating the excess of arsenious acid with standard iodine solution.I n the latter process, sufficient tartaric acid or alkali tartrate should be added to the acid solution to prevent the precipitation of manganese during the subse- quent neutralisation. If this precaution is not taken, errors may be introduced owing to the reoxidation of the precipitated manganous car- bonate by the iodine. A series of analyses made by the methods just described showed that the precipitate obtained in the chlorate process contains less oxygen than corresponds with the degree of oxidation of manganese dioxide, and that the average error thus introduced into analyses based upon the assumption that MnO, is precipitated amounts to more than 2 per cent.The oxide may, however, be obtained of a definite and constant composition by a modification of the process, based upon the observation of Wright and Menke that by the action of a dilute solution of potassium permsnganate, in presence of zinc sulphate, on manganous sulphate at SOo, an oxide is precipitated which, although combined with alkali, contains oxygen exactly in the proportion corresponding with the dioxide. Three-fifths of the manganese in the precipitate represents the amount originally present in the manganous sulphate. The following method of procedure is recommended. The solution of the manganous salt is evaporated to dryness, heated with nitric acid until oxides of nitrogen are no longer evolved, and concentrated nitric acid then added until the volume of the liquid is 85 C.C.Sodium chlorate , ( 5 grams) is added, the liquid boiled for 6 minutes, more nitric acid (15 c.c.) and a few crystals of the chlorate introduced, and the solution again boiled. After cooling, the pre- cipitate is collected on an asbestos filter, washed with water, dissolved in 2 C.C. of hydrochloric acid, and the solution evaporated with 5 C.C. VOL. LXXIV. ii. 47646 ABSTRACTS OF CHEMICAL PAPERS. of concentrated sulphuric acid until the hydrochloric acid is completely expelled. The solution of the manganous sulphate (containing not more than 0.5 gram of the salt) is nearly neutralised with potassium carbonate, mixed with solutions of zinc sulphate (2 grams) and potas- sium permanganate (1.5 grams), and the liquid, amounting to about 500 c.c., heated to SOo, and potassium hydrogen carbonate added in quantity rather more than sufficient to neutralise the acid still remain- ing.The precipitate is collected, washed with water, and its oxygen value determined by one or other of the methods described above. The results obtained by this process are very satisfactory. Estimation of Manganese as the Sulphate and as the Oxide. By FRANK A. GOOCH and MARTHA AUSTIN (Amer. J. Sci., 1898, 5, 209--214).-The authors state that the best may of estimating manganese is to weigh it in the form of anhydrous sulphate, provided it is not heated to too high a temperature. In their experiments, the solution of the manganous chloride was introduced into a weighed platinum crucible, and after adding a slight excess of sulphuric acid, the water mas removed by heating on the water bath. The crucible, supported by a porcelain ring, was then inserted in a porcelain crucible in such a manner that there was a space of about 1 cm.between the platinum crucible and the outer crucible, the latter being heated over a strong bunsen flame until the contents of the inner crucible were quite dry. The results quoted prove the accuracy of the process. If it is desired to weigh the manganese as manganosomanganic cjxicle, the residue should be treated with nitric acid, and the crucible heated in the upper part of the flame of a strong bunsen burner, in such a manner t h a t an oxidising flame covers nearly the entire wall of the crucible.For accurate work, the weighing as sulphate is, Estimation of Manganese separated as Carbonate. By MARTHA AUSTIN (Aslae7.. J. Xci., 1898, 5, 3S2-384).-The author confirms the statement of Guyard, that manganese may be completely precipitated by ammonium carbonate even in the presence of excess of ammonium chloride. Precipitated in this manner, the solution being heated to boiling, the precipitate is, of course, quite free from alkali salts, and may be converted by ignition into oxide, or, better still, weighed as sulphate (see preceding abstract). Attempts to weigh Volumetric Estimation of Iron in Hydrochloric Acid Solution by means of Potassium Permanganate. By 11. HAUFFE (Chem. Zeit., 1897, 21, 894--895).-The following reagents are required.A solution of potassium permnnganate representing about 0 a005 gram of iron per c c. ; an acid solution of manganous sulphate, made by dis- solving 100 grams of the crystallised salt in 1300 c . ~ . of water and adding 200 C.C. of sulphuric acid ; a cold saturated solution of mercuric chloride, and a dilute solution of stannous chloride.

To completely destroy organic matter, the liquid is mixed with potassium per- manganate and thoroughly boiled. When cold, the whole is made up to a definite bulk, and an aliquot part is taken for the titration.This is diluted to about 200 c.c., boiled, and stannous chloride added until the iron is completely reduced, any great excess being avoided; 100 C.C. of the mercury solution is now added, which should give a small but decided precipitate of calomel, and then 60-100 C.C. of the manganese solution. The liquid is rapidly cooled and titrated with the perrnsngana5e; the latter should be standardised in the same way, using pure iron wire for that purpose. L. DE K. Determination of the Reducibility of Iron Ores. By JOHAN G . WIBORGH (Chern. News, 1898, 78, 4-6). Conipaot ores are less readily reduced by the carbon and carbonic oxide in the blast furnace than other ores, and the peroxide of iron is more easily reduced than less oxidised ores.As ordinary chemical analysis does not indicate how an ore mill behave in the blast furnace, the author has devised an apparatus to test this factor. I n i t a vertical reduction tube, 1.6 metres long and 50 mm. in diameter, with a portion 35 mm. in diameter at the bottom, is suspended, 0.25 metre from the hearth, in a circular producer in which charcoal is burnt in a grate without forched draught. The temperature in this tube varies from 400' at 0.5 metre to 880' a t 1.5 metres from the top, whilst the gas produced contains from 3-2 t o 3.6 per cent. of carbonic anhydride and 30 to 33 per cent. of carbonic oxide, but when the tube is raised by 0.35 metre from the furnace there is 17 per cent. of carbonic anhydride.In this apparatus, reduction tests maybe made by exposing samples of pulverised ore to high temperatures, gradually or suddenly, and in any quantities, but conveniently 8 t o 10 grams in a wire gauze boat ; one or many a t a time may be tested. The author's practice is to suspend the boat in the 400' zone, the zone of dis- sociation of the reducing gas, for an hour, then to lower it directly into the hottest part of the tube, and after an hour to cool i t in a current of carbonic oxide. In the product, the carbon, total iron, and metallic iron are determined, and also the proportion (in units per cent.) that the oxygen found after reduction bears to the amount of oxygen that would be found if the whole of the iron was present as peroxide, the last factor being called the degree of oxidation. The carbon is deter- mined in Sarnstrom's apparatus by oxidising with chromic solution and absorbing the carbonic anhydride ; the metallic iron by treatment with sulphuric acid and measuring the hydrogen evolved ; the total iron by dissolving 0.25 gram in hydrochloric acid, filtering, evaporat- ing with sulphuric acid? dissolving in water, reducing with zinc, and titrating; the degree of oxidation by treating 0.4 gram of the sample with 5 C.C.of 10 per cent. sulphuric acid with agitation until the evolution of gas ceases, then warming with about 5 C.C. of sulphuric acid, sp. gr. = 1.23, until all the iron is dissolved, and titrating the solution with permanganate. In the case of refractory ores, the first solution is separated and the undissolved residue alone treated with a more concentrated acid, the solutions being mixed for the titration.

D. A. L. Separations with Alkali Chrornates. By HARRY BREARLEY (Chent. Newus, 1898, 78, 14-16. Compare this vol., ii, 460).-8epc6ru- tion oj- Iron and AZurninium--In solutions saturated with dissolved hydroxide, or in hot solutions containing free acetic acid, 0.5 gram of iron is precipitated by 10 C.C. of a solution containing 1 2 5 grams of potassium chromate per litre, whereas in the first case aluminium is only partially precipitated by 50 C.C.of the chromate solution, and in the second case i t is not precipitated a t a l l ; when, however, both metals are present in a solution, the iron is only precipitated by a much larger quantity of chromate and carries aluminium with it, so that the reaction cannot be adopted as a means of separation; this appears to be due to the fact that ferric chloride dissolves freshly precipitated basic aluminium carbonate, and aluminium chloride dis- solves freshly precipitated ferric hydroxide. I n solutions where only the free acid of a solution of iron and aluminium salts has been neutralised without forming dissolved hydroxide, the aluminium is not precipitated a t all by the chromate, whilst the iron is only imperfectly precipitated.The separation, of iron and chromium can also not be effected in solutions saturated with hydroxide. The separation of iron and nickel in such solutions by means of potassium chromate is good in the absence of acid, and practically perfect in the presence of 1 per cent. of acetic acid, and inasmuch as a large excess of the precipitant may be used without injurious effect, the separation is good even in the presence of aluminium, which latter may be retained in solution by tartaric acid in the subsequent cyanometric estimation of the nickel, a point, however, to be considered later by the author ; but in preparing t h e solution for this estimation i t is necessary in the pre- sence of chromic acid to add ammonium sulphate first, and t,hen to render alkaline with ammonia.The ammonium sulphate prevents the formation of a basic nickel chromate and also heightens the silver iodide turbidity. The separation of iron and copper by the chromate is even better than in the case of the nickel, and in both instancesthe chromate surpasses the acetate separation. The separated copper may be easily estimated by the soda-cyanide process (this vol., ii, 140, 258). D. A. L. By FRANK A. GOOCH and JOHN T. NORTON, jun. (Amel.. J. Xci., 1898,6, 168-175).- Friedheim and Euler having taken exception to the criticisms passed on their process by Gooch and Fairbanks (Abstr., 189’7, ii, 76), the authors state that, unless precautions are taken to exclude air, the results cannot be trustworthy. The apparatus is made by sealing a separating funnel on to a 100 C.C.Voit distilling flask; this is in turn connected with a Drexel wash-bottle, placed in cold water and containing solution of potassium iodide. 1’0 prevent even the slightest escape of iodine, it is fitted with a bulbed trap. About 0.3 gram of the molybdic acid and 0.75 gram of potassium iodide having been introduced into the distilling flask, the air is expelled by means of a The Iodometrio Estimation of Molybdenum.ANALYTICAL CHEMISTRY. 649 current of carbonic anhydride, generated in a Kipp’s apparatus from marble and hydrochloric acid containing some cuprous chloride. Forty C.C. of hydrochloric acid of 1 01 2 sp. gr. is then introduced by means of the separating funnel, and the whole is gently boiled in a current of the gas until exactly 10 C.C.of liquid is left in the distilling flask, when it may be assumed that the last traces of iodine have been expelled. The liberated iodine is then titrated with standard solution of sodium thiosulphate as usual. L. DE K. Estimation of Technically Available Molybdenum in Molyb- denite. By HUGO BORNTRACER (Zeit. ancd. Chenz., 1898, 37, 438).- About a gram of the mineral is digested (in a conical flask), for about 2 hours, with 25 C.C. of concentrated nitric acid ; ammonia is then added, and the liquid filtered. The undissolved portion is treated with acid a second time, and the united filtrates evaporated to dryness with excess of nitric acid; the residue, consisting of molybdic acid and ammonium nitrate, is then treated with 50 per cent. alcohol, in which the latter alone dissolves.The molybdic acid may be collected and weighed, or better, dissolved in 50 C.C. of normal ammonia, and the excess of ammonia titrated back with normal sulphuric acid. The metallic molybdntes in the ore, which are technically useless, escape estimation. M. J. 8. Patera’s Method of Estimating Uranium. By HUGO BORN- TRACER (Zeit. and. Clzem., 1898, 37, 436 -437).-The method, as given in Freeenius’s Anleitung xur puantitaticen Analyse, consists in dissolving the ore in nitric acid, adding a n excess of sodium carbonate, boiling, and filtering, by which means the uranium passes into the filtrate with only traces of other metals, and can be thrown down by sodium hydroxide as sodium uranate. This method gives fairly accurate results with rich ores, such as pitch blende, but when applied to poor ores the precipitate is liable t o be seriously contaminated with silica.It is therefore advisable t o dissolve it in hydrochloric acid (after igniting) and to precipitate the uranium by ammonia from the filtrate, This precipitate is more easily washed than that with soda, and after ignition is weighed as UrsO,. M. J. S. Estimation of Tin in Tin Salts. By A. FROENKEL and J. FASAL (Chern. News, 1898, 78, 100--101).-The solution of the tin salt con- taining 0.2 to 0.4 gram of metal is treated in a flask with a few drops of hydrochloric acid along with from 0.5 to 1 gram of aluminium wire and gently heated, I n about half an hour, when the tin is all precipitated, both metals are completely dissolved by heating with 10 C.C.of concentrated hydrochloric acid; the solution is rendered alkaline by sodium hydrogen carbonate and Rochelle salt, and then titrated with iodine, The results are low. n. A. L. Detection of Bismuth. By EGIDIO POLLACCI (Gccxxettcc, 1898, 28, i, 391-39 i).-Bismuth compounds containing bromine or chlorine colour the bunsen flame bright green; the iodide, oxide, or other bismuth compounds do not give this colour, W. J. P.650 ABSTRACTS OF CHEMICAL PAPERS. Analysis of Soils. By MAX PASSON (Zeit. angw. Chem., 1898, 777-781).-The author has slightly modified the process recommended by Dyer (Trans., 1894, 115), and operates as follows : 120 grams of the dry soil is introduced into a litre flask containing 600 C.C. of a 2 per cent.solution of citric acid, and after the lapse of half an hour it is shaken for half an hour in a Wagner’s apparatus. The liquid is then filtered and 100 C.C. is taken for the estimation of the potassium. This, after adding a few drops of phenolphthalein, is mixed with a slight excess of barium hydroxide, which precipitates the greater part of the citric acid; basic lead acetate may also be used, but baryta is better. The excess of barium, or lead, is precipitated by ammonium carbonate, and the liquid is then made up to 250 C.C. ; 100 C.C. of the filtrate, representing 8 grams of the soil, is evaporated in a platinum dish, the residue incinerated until the carbon is almost entirely burned away, and then powdered and boiled with dilute hydrochloric acid, the whole being evaporated to dryness.After gently igniting the residue, it is dissolved in water, filtered, and precipitated as usual with platinic chloride. Lime is best estimated by treating the earth in a litre-shaking flask for half an hour with 500 C.C. of standardised hydrochloric acid con- taining about half a per cent. of hydrogen chloride, and titrating an aliquot part with soda, using phenolphthalein as indicator. L. DE K. Contributions to Forensic Chemistry. [Detection of Phenol, Benealdehyde, Carbon Bisulphide, Picrotoxin, Coniine and Nicotine]. By H. MELTZER (Zeit. ccnal. Chem., 1898, 3’7, 345-358). -.Detection of Phenol and BenxaZdelup!e.-On heating to boiling an aqueous solution containing both phenol and benzaldehyde mixed with twice its volume of concentrated sulphuric acid, it becomes deep red, and (if not too dilute) gives a red, resinous deposit.On adding potash (after cooling) t o alkaline reaction, the resinous substances dissolve with fine violet-blue colour, and if the liquid, after acidifying, is shaken with ether, the colouring matter dissolves in it ; on evaporation, a residue is left which dissolves in dilute alcohol and is coloured blue by alkalis, but is colourless in presence of free acids. Half a milligram of phenol and one drop of benzaldebyde suffices for the reaction. Detection of Cccvbon EisuEphide.-Carbon bisulphide, treated with alcoholic potash, is converted into potassium xantbate, which, when boiled for a short time with ethylic iodide, yields diethylic thiocarbon- a t e ; as this, when boiled with ammonia, splits up into ethylic thiocarbamate and mercaptan, the latter by its odour affords a means of recognising carbon bisulphide, even when no more than two milligrams is present.The ethylic thiocarbamate can also be recog- nised, since on boiling with alcoholic potash it is converted into potas- sium thiocyanate which can be detected by its reaction with ferric salts. Another method consists in passing the vapour of carbon bisulphide along with carbonic anhydride over fused potassium cyanide, which is thereby converted into thiocyanate. A tube containing lead acetateANALYTICAL CHEMISTRY, 651 should be inserted in the series to arrest any hydrogen sulphide. Five milligrams of carbon bisulphide can be detected in this way, but the method is, of course, open to the objection that all volatile sulphur corn- pounds produce the same result.Detection of I'iwotoxin.-A trace of picrotoxin treated with benz- aldehyde (diluted with its own volume of alcohol to diminish the yellow colour which it gives with the sulphuric acid) and a drop of concen- trated sulphuric acid acquires a red colour, which, on gentle stirring, forms red streaks through the liquid. Detection of Coniine cmd Nicotine.-An alcoholic solution of coniine mixed with carbon bisiilphide acquires a yellow colour, nicotine gives no coloration, On adding to the yellow solution a few drops of ft dilute solution of copper sulphate (1 : ZOO) or ferric chloride, charac- teristic yellow to brown precipitates are produced ; nicotine gives no such precipitate, although with larger quantities of the metallic salts it yields feeble yellow colorations.The brown copper precipitate is completely removed by ether (after adding water). Lobeliine, aniline, and methylamine give feeble yellow colours with carbon bisulphide, but whereas these colours are no longer visible a t dilutions of 1 :500, coniine gives a distinct reaction at a dilution of 1 : 10,000. On dis- solving a trace of nicotine in epichlorhydrin and heating to boiling, a deep red coloration is produced, whereas coniine gives no coloration ; about 0.00025 gram of nicotine can be thus detected. Strong solu- tions of lobeliine give a similar colour, but dilute solutions give only a feeble yellow. Aniline, dimethy lamine, cadaverine, and ammonia do not produce any coloration.Characteristic Reaction of Cane-sugar. By G. POPASOGLI (Ann. Agyon., 1898,24, 141 ; from Bull. Assoc. Chirn. SUCY. Dist., 13, NO.^), -When 0.5 C.C. of a 5 per cent. solution of a cobalt salt and 5 C.C. of 50 per cent. soda solution are added to a 10 or 20 per cent. solution of saccharose, a stable amethyst coloration is produced, I n the case of glucose, a blue colour is obtained, which soon becomes greenish. The two sugars are readily distinguished, and it is possible to recognise the presence of a tenth of saccharose in glucose, and to detect addition of cane-sugar t o wine, condensed milk, &c. Honey gives a blue colour which changes t o pale green; lactose gives a n unstable blue. Substances to be examined should be freed from dextrin and gum by means of baryta and lead subacetate.According to Beeson, a slight quantity of saccharose, in presence of much glucose, gives the blue colorsltion of glucose in reflected light, whilst in transmitted light, at a distance of about 80 cm. from the eye, the violet colonr of saccharose can be seen (Exp Stat.

LE ROY (Compt. vend., 1898, 126, 1047--1048).-When an alcoholic solution of phloro- glucinol strongly acidified with phosphoric acid is added to meal and gently heated, any particles of sawdust that may be present acquire a n intense carmine-red colour, whilst fragments of grain are but slightly affected and starch remains colourless. A hydrochloric acid solution of phloroglucinol acts too energetically, and the difference between the wood cellulose and the grain cellulose is not sufficiently distinct.(3. H. B.

H e considers that the only exact method is that. of Gautier, in which the liquid is made alkaline by means of standard sodium hydroxide solution, the phosphates and other salts precipitated by barium chloride, and the residual alkalinity determined in an aliquot part of the filtered liquid, using phenolphthalein as an indicator. If this method is combined with the determination of the acidity by means of sodium hydroxide in presence of barium chloride and phenolphthalein without previous filtration, it is possible to determine the respective quantities of monometallic and bimetallic phosphates present.C. H. B. Estimation of Tartaric Acid in Presence of Citric Acid. By ARTHUR BORNTR~GER (Zeit. anal. Cher12., 1898, 37, 477--485).-To ascertain how far the process worked out by Warington and Grosjean (this Journ., 1875, 973 ; and Trans., 1879, 341) and investigated by the author (Abstr., 1886, 1082 ; 1887, 341), is suitable for the estima- tion of tartaric acid when citric acid is also present, mixtures contain- ing 0.5 t o 4 grams of hydrogen potassium tartrate with 0.5 to 5 grams of citric acid and 5 grams of potassium chloride were neutralised whilst hot by potash, cooled, made up to 50 c.c., and 6 C.C. of a 50 per cent, solution of citric acid added, stirred until a precipitate appeared, and left until the next day before filtering.The precipitates were washed with a 10 per cent. solution of potassium chloride saturated with hydrogen potassium tartrate, and finally twice with potassium chloride alone before titrating. It was found t h a t t.he mixture of 0.5 gram of tartrate and 5 grams of citric acid gave, under these conditions, no precipitate, but that a precipitate appeared when an additional gram of citric acid was added. In the cases where the citric acid originally present did not amount to more than twice as much as the tartrate, the use of 5 grams of citric acid as the precipitating agent gave fairly close quantitative results, but when the amounts of tartrate and (original) citric acid were about equal, 3 grams of citric acid sufficed for the precipitation. The following rule is therefore laid down; such a quantity of the Estimation of the Acidity of Urine.ANALYTICAL CHEMISTRY.653 mixture is t o be taken as corresponds in total acidity with 3 grams of citric acid. It is neutralised, &c., as above, and precipitated with 3 grams of citric acid. Should the amount of tartrate found be more than double t h a t of the citric acid found, the operittion must be repeated with the addition (to the original mixture) of enough citric acid to restore approximate equality. Should, on the other hand, the amount of tartrate found be less than half the citric acid found, equality must be restored by adding a weighed quantity of tartrate. &I. J. S. Polarimetric Estimation of Gallotannic Acid.By R. F. WOOD- SMITH and CECIL REVIS (Analyst, 1898, 23, 33-35).-The process? which is intended for the estimation of gallotannic acid only, but which may, perhaps, be also extended to other kinds of tannin, is based on the fact that, under certain conditions, gelatin forms with tannin a precipitate of definite composition. Consequently, if a E O ~ U - tion of gelatin be polarised before and after treatment with tannic acid, the difference in the two rotations will serve as an indication of the amount of tannin. The details of the process are as follows : 25 C.C. of a 9 per cent. solution of gold label gelatin in water a t 45' is put into a 100 C.C. evaporating dish and heated on the boiling water bath t o 60'; 1 C.C. of soluble albumin is then added, and the whole heated for 10 minutes with constant stirring. After cooling to 50°, it is again heated t o 100' and filtered; the precipitate is washed with boiling water and the filtrate made up to 50 C.C.a t 45'. The liquid, which must be perfectly transparent, is now examined in a Schmidt and Haensch polarimeter at 45'. Twenty-five C.C. of the same gelatin solution is now heated with tannin solution containing about 0.6 gram of gallotannic acid, and the liquid poured off into another dish, the precipitate being washed with boiling water. The turbid liquid is clarified a s before with fresh white of egg, and then again polarised. Each degree difference in polarisation (sugar units) represents 0.0673 gram of tannin. L. DE K. Detection of Cotton-seed Oil, Sesamd Oil, and Earth-nut Oil in Olive Oils.By MASSIMO TORTELLI and R. RUGGERI (Zeit. angw.

To detect sesame oil, 5-6 C.C. of the liquid. fatty acids is shaken with an equal bulk of strong hydrochloric acid and 2 drops of a 1 per cent. alcoholic solution of furfuraldehyde. Even ifanly 1 per cent. of the adulterant is present, it gives a characteristic carmine-red colour t o the acid. To test for earth-nut oil, the insoluble lead soap is first thoroughly exhausted with ether, and then shaken with this solvent in the presence of dilute hydrochloric acid. The ether is distilled off, and the residue of fatty acids is dissolved in 100 C.C.of 90 per cent. alcohol containing a drop of dilute hydrochloric acid, and the whole is heated to 60". After cooling t o 10-20° for about 3 hours, the crystalline precipitate654 ABSTRACTS OF CHEMICAL PAPERS. of lignoceric and arachidic acids is filtered off and mashed, first three times with 10 C.C. of 90 per cent. alcohol, and then several times with alcohol of 70 per cent. ; i t is then dissolved off the filter by boiling absolute alcohol, and to the filtrate is added 100 C.C. of 90 per cent. alcohol and a drop of weak hydrochloric acid; after heating to 60°, the whole is allowed to cool for 3 hours. The crystals are washed as before, and, finally, redissolved in boiling absolute alcohol.After evaporating the solvent, and drying the fatty acids at loo", the melt- ing point is taken; if this is between 74" and 75*5", it indicates the presence of earth-nut oil. The percentage divided by 0.048 represents the amount of the adulteration. L. DE K. Oxidised Cotton-seed Oil, and a General Method for the Analysis of Oxidised Oils. By WILHELM FAHRION (Zeit. ccngw. Chem., 1898, 781--785).-This is a study of the changes which take place in the constitution of cotton-seed oil when exposed t o the air. The experiments were made by saturating with cotton oil two pieces of wash-leather, previously exhausted with light petroleum, and then exposing them for 8 and 12 days respectively t o the air. The first piece mas exhausted with light petroleum, which was then evaporated; the second one was similarly treated, but yielded a further supply of fatty matter when again exhausted with ether.The three products thus obtained, on evaporation of the solvents, were then analysed, together with the original oil. The method employed was as follows. After taking the iodine, saponification, and acidity numbers as usual, 2 or 3 grams of the sample was saponified with 10 C.C. of 2N alcoholic soda, the alcohol evaporated, and the soap dissolved in hot water. It was then placed in a separating funnel, and decomposed with hydrochloric acid, 25 C.C. of light petroleum added, and, after thoroughly shaking, the whole was left over-night, when the clear aqueous liquid was drawn off, and the petroleum poured off from the undissolved sticky, oxidised fatty acids, the latter being slightly washed with more light petroleum. The residue left on evaporating the petroleum was weighed, dissolved in 25 C.C.of strong alcohol, titrated with N/2 soda, using phenolphthalein as indicator, and then shaken with light petroleum to dissolve the unsaponifiable matters. The oxidised acids are dissolved in hot alcohol, which is then evapo- porated in a weighed dish, allowance being made for :my mineral matter which may be present. By deducting from the petroleum residue the weight of the unsaponifiable matter, the proportion of non-volatile acids is obtained, the molecular weight of which can be calculated from the amount of soda used. The weight of the total petroleum residue, plus that of the oxidised fatty acids, represents the Hehner number.It appears that, as the oxidation proceeds, the iodine figure gets very lorn, being 108.8 in the original sample, and only 55.4, 46.3, and 29.1 in the others; the Hehner figure also fell from 94-22 t o 85.34, 83.62, and 74.20, and the non-volatile acids from 92.85 t o 63.53, 62.91, and 35.76. The inner saponification figure fell from 186.9 to 128.8, 128.9, and 74.4. The amount of unsaponifiable matter fell from 1.1 to 0.72 in the last sample, but showed a slight apparent increase in the others, The molecular weight of the non-ANALYTICAL CHEMISTRY. 655 volatile acids fell from 278.1 to 276.2, 273.2, and 269.1. On the other hand, the acidity figure rose from 2.2 to 13.3, 13.8, and 33.4; the total saponification figure from 190.4 to 223.1, 227.5, and 271.3; and the oxidised fatty acids from 0.27 to 20.70, 19.43, and 37.72. The melting points of the non-volatile acids rose from 35-36’ to 45-46’, 46O, and 51’.When cotton-seed oil is oxidised by means of alkaline potassium permanganate, a large quantity of volatile acids, chiefly butyric, is A New Method of Estimating Fat in Food, Flesh, Feces, &c. By LEO LIEBERMANN and SALOMON SZ~KELY (Pjiiger’s Archiv., 1898, ’72, 360-366).-The substance to be investigated is boiled with potassium hydroxide ; alcohol is added, and then sulphuric acid care- fully. After cooling, the mixture is extracted with light petroleum, the soap dissolved in the light petroleum is determined, and the fatty acids estimated by titration with decinormal alcoholic potash.F u l l details of quantities used and formuh for calculating the fat are given. The method is rapid, can be used with various forms of food-stuff, and gives results which closely approximate to the amounts found by the older method of ether extraction Fat Estimation by Liebermann’s Saponiflcation Method. By FERENCZ TANGL and J. WEISER (Pfliiger’s Archiv., 1898, 72, 367-369).-The method, the principle of which is given in the preced- ing abstract, was compared with Dormeyer’s gastric digestion method ; flesh and faces were examined. The numbers came out approximately the same; on the average, the new method gives slightly higher results. The main advantage of the new method is its rapidity. Offlcial Instructions for the Examination of Fats and Cheese (Zeit.anal. Chenz., 1898, suppt. 7-30).-These official in- structions, published on April lst, 1898, by the Imperial Chancellor, prescribe in minute detail the mode of sampling and of carrying out the following analytical operations. Estimation in butter, margarine, lard, and other fats and oils, of the amounts of water, casein, milk- sugar, total ash, chlorine, &c.; detection of boric and salicylic acids, formaldehyde, artificial colouring matters, sesame, cotton seed, and other vegetable oils (by the phytosterol reaction) ; determination of the melting and solidifying temperatures of the fats and fatty acids, of the refractive index with the Zeiss refractometer, of the acid number, Reichert, Meissl, Kottsiorfer, Hehner, and Hub1 values, the non-saponifiable constituents, &c.In the case of cheese, the estimations of water, fat, total and soluble nitrogenous constituents, free acids and mineral constituents, and the procedure for ascertaining the origin of the fats present are described. The method of using the refracto- meter is very fully described, but it does not admit of serviceable abstraction apart from the illustrations given. By KARL DIETERICH (Zeit. anyw. Clwn., 1898, 915-919).-The author considers a sample t o be com- mercially pure if it conforms to the following tests, It should be transparent, and when boiled with water should only give the faintest obtained.

It should leave practically no ash, and be entirely soluble in alcohol, oil of turpentine, ethereal oils, acetone, ether, chloroform, methylic alcohol, amylic alcohol, ethylic acetate, benzene, and carbon bisulphide ; par tially soluble in petroleum, the portion insoluble in light petroleum of low boiling point not to exceed 7 per cent.The acidity figure should vary from 145 to 185 ; the sp. gr. from 1.045 to 1.085. The acidity is determined by dissolving 1 gram of th6 powdered sample in 25 C.C. N/2 alcoholic potash, allowing it to act for 2 hours in the cold; the excess of alkali is then titrated with N/2 sulphuric acid ; no water should be added. The sp. gr. is conveniently deter- mined by means of weak brines of sp. gr. varying from 1.070 to 1.085. By EDUARD HIRSCHSOHN (Zeit. anal.Chern., 1898, 37, 456-457 ; from PILurna. Zed. Russ., 31, 609).-The estimation of the acid number does not give trustworthy results in this case. Colophony is readily dissolved by aqueous ammonia (0.96), and is reprecipitated by acids ; dammar resin yields a yellowish or reddish extract, which gives a feeble opal- escence with acids. The resin is digested with the ammonia for half a n hour, and the filtered extract acidified with acetic acid. Five per cent. of colophony can be detected. M. J. S. Detection of Colophony in Guaiacum Resin. By EDUARD HIRSCHSOHN (Zeit. anal. Chem., 1898,37, 459 ; from Pharm. Zeit. .Rum, 34, 513).-The method prescribed by the Russian Pharmacopoeia consists in precipitating the resin by water from its alcoholic solution and shaking the precipitate with potash, when the guaiacum dissolves to a clear solution, whilst colophony gives a turbid solution and a pre- cipitate of resin soap.The method may be applied directly t o the original resin. The powdered substance is shaken with potash solu- tion of about 15 per cent. ; a stronger solution mould precipitate the potassium salt of the guaiacum resin, whilst a weaker one fails to pre- cipitate the colophony soaps. The presence of soda must be avoided. Another method is to shake the finely powdered resin with 4 or 5 parts of light petroleum, and mix the colourless filtrate with an equal volume of a 0.1 per cent. aqueous solution of cupric acetate. The presence of colophony is revealed by a blue or bluish-green colour. Should less than 10 per cent.be present, the petroleum solution would need concentrating. M. J. S. By ADOLF JOLLES (Zeit. anal.

Vocl~nslw., 1896, No. 48), yields bluish-violet colours when oxidised b r ferric chloride, nitric and nitrous acids, and the halogens. Most of these colours rapidly fade and disappear, but the blue colour obtained with alcoholic iodine solution passes, after some time, into red. Hydrogen peroxide gives a blue colour only on warming ; acidified permanganate acts too energetically, producing only colourless compounds.

Detection of Quinine, By EGIDIO POLLACCI (Gccxxetta, 1898, 28, i, 391-394).-The author detects quinine by the formation of thalleoquinine as follows. A centigram of the quinine compound is dissolved in 1 C.C. of water and 2 drops of sulphuric acid. A small piece of lead peroxide is then put in, and the liquid gradually heated to boiling; after adding 3-4 C.C. of water and allowing to stand, a layer of ammonium hydroxide is poured in, when an emerald green disc or ring is produced.By S. VREVEN (Chena. Centr., 1898, i, 225 ; from Pharrn. Centr.-H.., 1897, 38, 867).-Three hundred C.C. of the urine,after standing for S days,is made alkaline with ammonia, and after shaking with chloroform, the emulsion is drawn off and mixed with a little alcohol, which will cause the chloro- form to separate ; this is then shaken with acidified water, and the aqueous liquid is again made alkaline with ammonia and agitated with chloroform, Finally, the chloroform extract is evaporated, and the resi- due, dissolved in a drop of acidified water, is treated on a microscopic slide with a minute drop of a solution of 10 grams of potassium iodide, and 5 grams of cadmium iodide, in 100 C.C. of water (Marmd’s reagent), and stirred until the milky liquid has become clear again.Crystals soon begin t o form which, under the microscope, show very charac- By C. C. KELLEEC (Chem. Centr., 1898, i, 222 ; from Ber. Deutsch. Pharna. Ges., 7, 4’70-471).- Kiliani having stated that digitonine does not occur in digitalis leaves, the author has repeated these experiments, and has come to the con- clusion that Kiliani’s digitaline was in reality digitonine. If 0.01 gram of this alkaloid, dissolved in 5 C.C. of hydrochloric acid of sp. gr. = 1.19, is heated on the water batb, the liquid turns first yellow, then deep red, and finally dark blue. If, when cold, 20 C.C. of water is added, a blue liquid with a red fluorescence is obtained which soon diminishes. Of the other digitalis akaloids, digitaline alone gives By C.HARTWICH (Amh. Pharm., 1898, 236, 172-199). -The author considers in detail the morphological characteristics of cubebs, and of fruits which are employed for their adulteration. It is pointed out that amongst the latter are fruits which contain no cubebin, and yet cannot be distinguished, either in appearance or microscopically, from t r u e cubebs; as, however, they fail to yield a red coloration with sulphuric acid, owing t o the absence of cubebin, an easy means is afforded for their detection. Detection of Albumoses in Urine. By IVAR BAXU (Zeit. a n d Chem., 1898, 37, 410-411); from Deut. wed. Woch., 1898, 1’7).- To avoid the disturbing effect of urobilin in testing for peptones with phosphomolybdic acid, 10 C.C. of the urine, t o which, in a test W.J. P.

The upper liquid is decanted, the sediment washed with alcohol, which also is poured off and can be tested for urobilin, and the residue is dissolved in a little water, and, after filtration, tested for the biuret reaction. Other colouring matters in urine are without influence. Should the alcoholic extract be red and show the spectrum of hzematoporphyrin, the urine may be first precipitated by barium chloride in order to remove that substance.Estimation of Proteids. By N. C. HENRIK SCHJERNING (Zeit. and. Chem., 1898, 37, 413-422).-This communication is mainly a summing up of the author’s earlier papers on the same subject (Abstr., 1894, ii, 371; 1895, ii, 428; 1896, ii, 631 ; this vol., ii, 271, 416). The reagents used are those described i n Abstr., 1896, ii, 631, with the addition of a 5 per cent. mercuric chloride solution, which is used instead of lead acetate when that reagent does not give satisfactory results. I n all cases, the proteid solution should be so far diluted that 10 C.C. of it contains nitrogen corresponding with 5 C.C. of N/10 acid.If a quantity of the solution sufficient to require 10 C.C. of N/10 acid fails to precipitate all the iron from 0.8 gram of ferric acetate (Abstr., 1896, ii, 631), the substance is regarded as poor in ash, and calcium chloride or sodium phosphate is added prior to the precipitation with tin, lead, and iron respectively. In all cases, the precipitation takes place in an acid solution. The criterion of a satisfactory precipitation is that a clear filtrate contain- ing (except in the case of ferric acetate) an excess of the reagent is obtained. After collecting the precipitates on an 11 cm. extracted filter, it suffices to fill the filter twice with the appropriate washing liquid; the iron precipitate alone requires 3-4 washings. The analytical numbers are finally worked out as follows : the stannous chloride precipitate (a) contains albumin I ; the lead acetate or mercuric chloride precipitate (b) contains albumins I and 11, and denuclein ; the ferric acetate precipitate ( c ) contains the above with propeptones ; the uranium acetate precipitate (d) contains peptone in addition to the others; and the magnesium sulphate precipitate (e) contains the two albumins and the propeptones. Thence a = albumin I ; b - [CG + (c - e ) ] = albumin I1 ; c - e = denuclein ; G - 6 = propeptones ; d - c = peptones.By P. CARLES (Chenz. Gentr., 1898, i, 226 ; from Rev. Intewz,. Fcdsif., 10, 203).-Jean has published a process for the estimation of gelatin in meat extracts based upon its precipitation by tannin and the estimation of the excess of the latter by titration with iodine. The author points out that various kinds of gelatin combine with vrtrious quantities of tannin ; for instance, 1 gram of tannin precipi- tates 1 gram of isinglass, 0.91 gram of gelatin, 0.87 gram of so-called Bordeaux-gelatin, and 0.80 gram of glue ; also 31 grams of white of egg, 25 grams of blood-serum, and 3.10 grams of commercial albumin.M.

Chew,., 1898, 25, 406-410).-The following method is recommended. The urine is precipitated with 20 per cent. solution of lead acetate, and the clear filtrate decomposed with the same volume of Obermayer’s reagent. The mixture is then extracted with chloroform until the extract is colourless ; the chloroform is evaporated, the residue dried on the water bath, and a few C.C. of concentrated sulphuric acid added ; after 24 hours, 100 C.C. of water is added, and the liquid titrated with potassium permanganate. Various precautions to be adopted during the analysis are described fully. The author’s results are reserved for a future paper. By A. BINZ and F. RUNG (Zeit. angw. Chern., 1598, 904--905).-The authors think the following process is the best of all the methods as yet proposed. Ten grams of the cotton is boiled for 3 or 4 hours with 150 C.C. of glacial acetic acid in a Soxhlet’s apparatus, and the acid is poured into 300 C.C. of water mixed with 150 C.C. of ether; the indigotin is completely precipitated, but remains suspended in the ethereal layer. The aqueous layer being removed by means of a separating funnel, the indigotin is collected on a weighed filter, washed with alcohol and ether, dried, and weighed. Cellulose is also slightly dissolved by the acid, but the acetylised Chemistry of Tobacco. By RICHARD KISSLING (Chena. Zed., 1898, 22, 1--4).--Estimcctiort of the Moisture.-The moisture is best deter- mined by first partially drying the sample over sulphuric acid; when dry enough t o be powdered, it is weighed, and then reduced to a fine powder; I gram of this is then dried over sulphuric acid for 24 hours, when it will generally be quite dry. The dried tobacco is very hygro- scopic, and, after 24 hours, will have reabsorbed nearly all its original moisture. Estimation of Malic ccncl Cit& Acids.-The following method is proposed. Ten grams of the powder containing about 4 per cent. of moisture is put into a porcelain basin and thoroughly impregnated with 10 grams of dilute sulphuric acid; the mass is now mixed with about 10 grams of powdered pumice so as t o obtain a reasonably dry mixture, which is placed in a filter paper cartridge and extracted for 20 hours with ether t o dissolve the organic acids. The ether is then corresponds with the amount of scatole. L. DE K. Estimation of Urinary Pndican. W. D. H. Estimation of Indigotin on the Fibre. product remains dissolved in the ether. L.

To find the amount of malic acid, the neutralised liquid is cooled to Oo, which causes the barium citrate to crystallise out ; the precipitate is then washed with 20 C.C. of cold water, afterwards with 50 C.C. of a mixture of equal vols. of alcohol and ether, and the barium malate is completely precipitated by adding t o the filtrate 160 C.C. of the same ether-alcohol mixture. The pre- cipitate after being washed with a little ether-alcohol is dried and ignited, and from the amount of ash (barium carbonate) the amount of malic acid is calculated. The barium citrate precipitate is treated in the same manner. L. DE K.
