1164 ABSTRACTS OF CHEMICAL PAPERS.Chemistry of Vegetable Physiology and Agriculture.Submersion of Vineyards. By P. DE GASPARIN (Conzpt. rend.,96, 1552-lP555).-0ne of the best methods of preventing tlieravages of the phylloxera is to keep the soil of the vineyard con-tinually moist, and in the south-east of France this is effected bysubmergink the vineyard during winter. The soils which are thustreated are compact argillo-calcareous soils which, with one or twoexceptions, contain more than 30 per cent. of impalpable constituents,and more than 30 per cent. of calcium carbonate. Soils of this clia-racter are sufficiently pervious to allow the water to diffuse throughthem by capillary action, and yet are sufficiently impervious to pre-vent the water passing through them rapidly.I n those cases wherethe surface soil is sandy, the subsoil is found to be compact, calcareous,and argillaceous. The same method of treatment is, however, applirdsuccessfully to the dunes of Aigues Mortes and t o other sandy soils.C. H. B.Sap. By J. ATTFIELD (Pharm. J. Tmns. [3], 13, 819-d.LO).-Thepresent paper coiitains an account of observations made on sap exud-ing from a wounded silver birch tree. A branch had been lopped ot€a birch tree 39 feet high, and 7 inches in diameter about 10 feet fromthe ground, before the leaves had expanded, leaving a wound about aninch in diameter, from which sap dropped. A bottle was suspendedso as to catch the sap, and from observations taken, it was found thatthe flow was apparently faster in sunshine than in the shade, and byday than by night, ; and altogether aruoiinted to about 4 litres a day,this had been running for 15 days, but how long it would continue isuncertain, The sap was clear and bright, sp. gr.1.005, had a faintlysweet taste and a slightly aromatic odour. After 12 hours it depositedR trace of a sediment which, wheii examined microscopically, was foundto consist of parenchymatous cells and a few so-called sphere-crystals.The liquid contained 99 per cent. water and 1 per cent. solid matter,which was composed mainly of sugar 91 per cent., the other consti-tuents being ammonium salts ; albumino'ids ; nitrates ; phosphates,and organic sslts of calcium and magnesium ; mucilage, and traces ofnitrites and potassium salts. It had calcium and magnesium salts insolution equal to 25 degrees of total permanent hardness.It conVEGETABLE PHYSIOLOGY AXD AGRICULTURE. 1165--3 *741 *082-902 .040.781-760.34trace1.130.43tained a ferment capable of converting starch into sugar, and whenexposed to the air, it soon teemed with bacteria, the sugar beingchanged into alcohol.Effect of Altitude on the Alkaloids of the Bark of CinchonaSuccirubra. Ry J. E. HOWARD (Pharm. J. Trans., 13, 1013-1015).-After some remarks on the growth and cultivation o l cinchonas ingeneral, in which the abthor makes special reference to the physicalrelationship existing between quinine and cinchonidine (both levo-gyrate), and between quinidine and cinchonine (both dextrogyrate) ;attention is drawn to the results of the analyses of two specimens ofred bark (C.succirzibrn) from two trees of common origin ; they werealso of the same age, 19 years old, and had grown up under fairlysimilar conditions, climatic excepted,-the one, A, being cultivated atHakgala, 5,500 feet elevation, being the larger of the two trees, yield-ing 25 lbs. of dry bark, with a " brown coat ;" the other, B, yielding7 lbs. of dry bark " with a grey coat," was cultivated at Peradeniya,1,500 feet elevation.D.

Quinine and cinchonidine inthe former seem to have replaced the quinidine and cinchonine ofthe latter. D. A. L.Cinchona Bark grown in Jamaica. By B, H. PAUL (Pharm. J.T1.an.s.

Comparing these resultswith analyses made some few years back, it is inferredthat in mostcases the quality of the bark has improved.The reverse, however, isthe case with the “ calisaya ” plants ; perhaps for the reason givenabove. D. A. L.Seeds of Camellia oleifera. By H. MCCALLUM (Pharm. J: TYU~S.[3], 14, 21).-The CameZZia oZeifera grows abundantly in China, wherethe seeds are gathered and the oil pressed out and used for hair dress-ing and illuminating. The residue is made into cakes or powdered,the powder being used for washing purposes, especially for extractinggrease spots ; an infusion of it is also made for killing worms, grubs,&c., and even fish. The cakes are used with water as a hair wash. Theseeds contain a glucoside, saponin, as well as the oil. 44 per cent.ofoil may be extracted by means of ether, using a Soxhlet’s tube, and10 per cent. of saponin from the residue by treatment with 84 per cent.alcohol ; even after this treatment it is soapy.The oil is viscid, yellowish, scentless, with an unpleasant aftertaste, and is not soluble in 84 per cent. alcohol. The saponin is notquite pure, as it leaves 0.9 per cent. ash. It is a friable amorphouswhite powder, which irritates the nostrils ; when dry it is almostodourless, bnt its aqueous solution has a disagreeable odour. Its tasteis a t first sweetish, then bitter and disagreeable, causing a biting sen-mtion in the throat. It is hygroscopic, very soluble in watey, freelyin 84 per cent. alcohol, sparingly in absolute alcohol, and insoluble inether.An aqueous solution is precipitated by barium hydroxide, byFehling’s solution, by basic lead acetate in the cold, and by normallead acet8ate and dilute hydrochloric acid when warmed ; in the lastcase a glucose remains in solution. When the aqueous solution isboiled with Fehling’s solution, a slight reduction takes place, Itforms emulsions with oils and chloroform; and when it is shakenwith mercury, the metal is reduced to a fine grey powder.D. A. L.Occurrence of Nuclei’n in Moulds and in Yeast. By A. STUTZER(Zeitschr. PhysioZ.

[el, 27,422-423) .-Preliminary experimentson reactions in sealed tubes can be readily effected wit,h the use of onlya few milligrams of substance by employing tubes itmade of ordinarytubing) 5-6 c.m. long and 3-4 mm. wide, sealed a t one end anddrawn out a t the other to a thick-walled capillary tube of 10-15 c.m,long. This tube is then fixed by means of a split oork in a test tnbecontaining a liquid boiling a t the temperature required.Alkalimetric Indicators. By J. WIELAND (Ber., 16, 1989-1991) .-The author has examined the relative sensitiveness of variousitzo dye-stuffs proposed as indicators for alkalimetry. Of substancesnot affected by carbonic acid, ethyl-orange is t h e most delicate;2 drops of a 0.05 per cent.solution is sufficient for 50 C.C. t o obtain asharp change of colour. The analytical resulks are compared in theoriginal memoir in a tabularform.Separation of Chlorine, Bromine, and Iodine. By J. B.BARNES, Juiir. (Phnrm. J. Tmn.s. [ 3 ] , 13, 940--942).--The author hastried a few experiments on the efficiency of Vortrnann’s process,already described (this vol., 119), for qualitative purposes. Heremarks that practically iodine is wholly expelled from a solution ofan iodide by evaporating almost to dryness four times with either leadA. J. G.V. H. Y1168 ABSTRACTS OF CHEMICAL PAPERS.or manganese dioxide and 3 per cent. acetic acid ; on the other hand,bromine is only expelled from bromides when strong acid (33 percent.or abovej is used ; whilst chlorides treated in a similar mannerare b u t very slightly decomposed, or not a t all. I n this manner alsothe iodine and bromine are readily expelled from a mixed solution ofiodides and bromides ; provided the lead oxide is added little by little,while the acidified solutions are in a state of ebullition, thus prevent-ing the formation of iod'ic acid (ibid). I n a mixture of chlorides,bromides, and iodides, chlorine alone could be detected after theftjurth evaporatoin with 33 per cent. acetic acid and lead dioxide.Another experiment proved that iodine could be removed from asimilar mixture by treatment with manganese dioxide, whilst thebromine could be separated from the chlorine by subsequent treat-ment with lead oxide.The last experiment can be utilised to ad-vantage for testing for these substances ;-The maw t o be tested isput into a dish, and ordinary acetic acid and manganic oxide are addedto i t ; the appearance of a brown colour indicates iodine, if it ispresent, the whole is boiled vigorously until the vapour ceases to" blue " starch-paste, showing that the iodine is removed. Now testfor bromine (or in case there is no iodine; test a t ance previous toboiling), and if it is present boil with acetic acid and lead oxide untilthe vapour does not turn starch-paste and potassium iodide blue,showing the total expulsion of bromine. The residue is filtered andtested for chlorine. An objection t o the use of manganic oxide is, thatsolutions containing it are "very liable to spurt during evaporation.D: A.L.Detection of Free Sulphuric Acid in Presence of AluminiumSuIphate. By 0. M~LLER (Ber., 16, 1991--199E).-In the papermanufactory the detection and estimation of sulphuric acid'is of greatpractical importance. The experiments of the author prove that ofthe indicators hitherto proposed, methyl-orange is the most delicatefor the detection of free sulphuric acid in presence of aluminium sul-phate. The degree of dissociation on boiling an aqueous solution ofthis salt can be determined by the use of methyl-orange. For thequantitative estimation of the free acid in aluminium sulphate, itssolution is precipitated by alcohol, and bhe filtrate evaporated over asmall game, and then titrated.Experiments are quoted to prove theaccuracy OP the process. Ethyl-orange, although the most sensitiveindicator towards free acid, yet is coloured a rose tint by neutralaluminium sulphate, which prevents the observabion of the neutralEstimation of; Iron by means of Permanganate Solution.By J. KRUTWIG and A. COCHETEUX (Be?., 16, 153P-l536).--Theauthors find that the inaccuracy due to the presence of hydrochloricacid may be avoided if tlie followinq conditions are observed :-TheOre should be dissolved in the smallest possible quantity of hydro-chloric acid, reduced by means of zinc, sulphuric acid added inquantity double that of the hydrochloric acid, the solution diluted to300 C.C. and titrated with a dilute solution of potassium perman-gin;.te .point. v.

STORCH(Ber., 16,2014-2015) .-If hydrogen sulphide be passed into a solutionof tin chloride or ammonium tin chloride mixed with an excess ofan iron salt, a dirty yellow or greyish-green precipitate is formed,containing tin and iron in the proportion of 100 to 4. This pre-cipitate is soluble in hydrochloric acid, and hydrogen sulphide pre-cipitates from the solution tin sulphide only ; warm potash, ammonia,or sodium hydrosulphide dissolves the tin precipitate, and the solu-tions, when allowed to stand, deposit the iron as hydroxide or sul-phide.Ammonium sulphide dissolves the tin, leaving the ironsulphide. V. H. V.Solubility of Metallic Sulphides in Thio-acids. By L.STORCH (Bey., 16, 2015--2016).-The precipitation of copper as sul-phide is prevented in a most marked way, not only by thio-molybdates,(Debray), -arsenates, and -stannates (Berzelius), but also by thio-tungstates and -vanadates. This phenomenon is also more noticeablewith cuprous than cupric salts. Similarly the precipitation of iron,mercury, and cadmium sulphides is prevented by the above-namedacids, especially thiostannates. The resultant solution is either clearor contains the thio-salt of the precipitable metal in the collo’idalstate. Thus, for example, on adding ammonium sulphide t o ferricchloride, in presence of ammonium molybdate, a green solution isobtained, which after a time deposits the iron thiomolybdate ofBerzelius. V.H. V.Detection of Mercury in Animal Tissues. By H. PASCHICIS(Zeitschr. Physiol. Chem., 6, 495--503).-Until a; few years ago, elec-trolysis was almost exclusively employed in the examination of animaltissues for mercury. Schneider’s method left little t o be desired inpoint of delicacy and accuracy, but was tedious in detail, and theapparatus somewhat complicated. E. Ludwig’s method for theseparation of mercury from the tissues is, however, easier of applica-tion, and needs much less time, whilst equal in other respects to theformer. By it the mercury is separated from the largely dilutedsolution by means of finely divided zinc or copper, from which, bysimple heating, the metal is obtained directly.Originally Ludwigdistilled the mercury from the washed and dried zinc-dust in a slowcurrent of air, passing it over a layer of red-hot oxide of copper, tocomplete the combustion of other products of distillation, and con-densing mercury and water in a quill-sized capillary tube. Subse-quently he has so far modified the process as to dispense with the air-stream, heating the zinc amalgam in a tube closed at one end, andgetting rid of the aqueous vapour by passing the products over alayer of ignited zinc-dust before their entrance into the capillarytube.Furbringer has proposed a modification of Ludwig’s process, in sofar that he substitutes the so-called brass-wool for the zinc, whichafter removal from the mercurial solution is washed in water, alcohol,and ether, dried and heated in a tube drawn out at both ends in whichthe mercury becomes condensed (Berlin.Klin. Wochenschr., 1878,VOL. XLIV. 41170 ABSTRACTS OF CHEMICAL PAPERS.p. 332). Recently V. Lehmann has adversely criticised Ludwig’smethod, and concludes that it is neither accurate nor simple andexpeditious. This opinion is quite contrary to the experience of theauthor of this paper as well as of Guntz, 0. Hassenstein, and Ober-lander, whose results are likewise confirmatory of the accuracy ofLudwig’s process.The fact that Lehmann’s criticism called in question the validity ofcertain investigations made by the author conjointly with L.v. Vajda,induced him to repeat a series of experiments with this process andits modifications.1. Ludwig’s Method-About 400 C.C. of normal urine, containinga known amount of mercuric chloride, were warmed to 60--70”,acidified with hydrochloric acid, about 3 grams of zinc-dust added,and after agitation for some time the clear solution poured off, andthe resulting amalgam washed several times, first with pure waterand then with water to which a few drops of pot’ash solution hadbeen added. After drying upon the water-bath, this amalgam wasintroduced into a tube of hard glass of about 8 mm. diameter, closeda t one end with successive layers of asbestos, coarse cupric oxide, andzinc-dust in front : the tube being then drawn out to a capillary boreof the thickness of an ordinary straw, was placed in a small combus-tion furnace, the cupric oxide first raised to a low red heat, the zinc-dust moderately heated, and at last the amalgam is strongly ignited.I n 10-15 minutes the mercury is found in the capillary portion ofthe tube, which is then cut off, a small fragment of iodine inserted inthe widest part, and gently heated.I n five such experiments, inwhich the quantities of mercuric chloride used were respectively 0.005,0.002, 0*001, 0*0005, and 0.0002 gram, distinct iodide sublimates wereobtained. In a sixth experiment, in which 0.0002 gram of mercuricchloride was added to 400 c.c- of urine, also containing albumin, theresult was equally decided.2. FGrbriqer’s Method-400 C.C. of the same urine, as preparedfor the above experiments, was similarly treated, brass- wool beingsubstituted for the zinc-dust.The wool, after washing with hotwater, alcohol, and ether, was introduced into a tube of 8 mm.diameter, drawn oub in capillary fashion at both ends, heated over aBunsen lamp, and a fragment of iodine introduced into the still warmtube. In three experiments in which 0.001, 0.0005, and 0.0002 gramof niercuric chloride were employed, a distinct reaction was obtainedin both of the capillary extremities of the tube. In a fourth instance,the reaction was also distirictly given by 50 C.C. of urine taken fromthe body of a man who had poisoned himself with corrosive sub-limate.3. Modification of Ludwi.y’s Method-The advantage shown in wash-ing t,he zinc-amalgam with a weak alkaline solution, whereby organicmatters, especially uric acid, are removed, and empyreumatic productsavoided in the subseqnent distillation, induced the author to dispensewith the layers of cupric oxide and zinc-dust in the combustion tube.The latker conhaining only the zinc-amalgam, was heated over a Bunsenlamp, as already described, and distinct reactions were yielded bysimilar quautities of mercuric chlorideANALYTlCAL CHEMISTRY.11714. Experiments with Leaf-gold.-The process was the same as inthe previous experiments, the lea€-gold washed with ether, dried on awatch-glass in the water-bath, and after kneading into a pellet intro-dnced into a thick glass tube of 3 nim. diameter, closed at one endand drawn out a t the other.The sublimate of mercury obtained uponheating in the capillary portion, gave a distinct reaction with iodinein each of the four experiments in which the quantities of mercuricchloride employed were respectively 0.002, 0.001, 0*0005, and 0*0002gram. The author concludes that Ludwig's process, in skilfulhands, is neither complicated nor tedious, whilst in point of delicacyit is at least equal to its several modifications. Furbringer's processis undoubtedly somewhat quicker and more simple in its details, butit must be borne in mind that the same intimate contact of solutionmid metal attainable in the case of zinc-dust, is hardly to be expectedwhen brass-wool is employed. The process is most simplified by thesubstitut,ion of leaf-gold. The deRtruction of the urine by potassiumchlorate and hydrochloric acid, as proposed by Lehmann (t,his vol.,p.687), is in no case necessary. Lastly, an objection lately urgedagaiust Ludwig's method by Schuster, that the simultaneous distil-lation of the zinc itself may conceal the mercurial sublimake, ispossible only when excessive ignition has been resorted to. Thatthe iodides of arsenic orbismuth should be mistaken for mercuriciodide is, as already shown by Ludwig, only conceivable in inexperi-enced hands. D. P.Determination of Organic Matter in Potable Water. By J. W.MALLET (Chern. News, 47, 218-220 and 232-2233).-Apparatus isdescribed, whereby the water to be examined may be evaporated undergreatly reduced pressure and at, a correspondingly low temperature,out of contact with the air.Under such conditions the organicmatter is altered much less than in the apparatus generally made useof. As test materials, leucine and tyrosine were selected, as repre-senting the more stable products of putrefaction liable to occur innatural water, and for which the combustion process in its usual formhad been found to give results far from satisfactory. Sixteen experi-ments were made; from leucine 95.77 per cent. of the total carbonwas obtained (9i.24 to 91*40), and 93.32 per cent. of the total nitrogen(95.64 to 88.27) ; whilst from tyrosine 97.04 per cent. of the carbon(98*13-92.65), and 95.72 per cent. of the nitrogen (97.29 to 90.45)were obtained. These numbers show a marked improvement on resultspreviously obtained, and the error in the determination of the twoelements is in one direction, Tiz., a partial loss.It has been proposedto remove nitrogen existiiig as ammoniacal salts, by treatment wit11magnesia, before estimating the organic nitrogen, but it is found thata t 40" to 45", urea in a very shGrt time begins to evolve ammonia ; stillin waters containing relatively very large quantities of ammoniacalsalts the error due to the decomposition of urea, &c., would be per-haps less than that attributable to the dissociation of these saltsduring the evaporation, t o an extent not accurately determinable. Ithas been proposed to remove nitrates and nitrites by the reducingaction of phcsphorous or hypophosphorous acid ; solutions of tyrosin1178 ABSTRACTS OF CHEMICAL PAPERS.Solvent.- ---- r Ammonia, 5 p.c. ; sp. gr. 0.998 4 ,and potassium nitrate were evaporated with addition of phosphorousacid, the residue just neutralised with magnesia, and then broughtto a suitable condition by the addition of pure silica and dryingin the previously described vacuum apparatus. On combustion,results were obtained for the carbon and nitrogen of the tyrosineas good as those obtained from solntions of this substance in purewater. A series of experiments under different conditions showedthat on distilling a very dilute solution of ammonia a not incon-siderable amount is lost ; thus under ordinary conditions it amountsto about 14 per cent. of the whole.In this case the temperatureof the distillate was about 28", but by reducing this to Go, theaverage loss became only 2 per cent. If a current of air be drawnthrough or over a dilute solution of ammonia-0.5 mgrm. in 500 C.C.-the ammonia is very slowly removed, but a t a temperature of 50-60": the whole of the ammonia may be removed in about 16 hours. Asolution of urea when boiled or kept a t a high temperature is decom-posed gradually with evolution of ammonia, but a t lower teinpera-tures, i.e., 50-60", this decomposition is much less rapid. A fewexperiments were also made to test the modification of the permanga-nate process proposed by Tidy, viz., the maintenance of an approxi-mately constant excess of permanganate ; the modification seems tobe an improvement, but further experiments are required.H.R.Coefficients of Solubility of some Silver Salts, and SystematicMethod of Testing for Hydrocyanic, Hydrochloric, Hydrobro-mic, Hydriodic, Chloric, Bromic, Iodic, Hydroferrocyanic, andHydroferricyanic Acids.

When the reduc-tion is complete, the liquid is divided into three parts ; in one hydro-cyanic acid is tested f o r by a ferrosoferric salt; another is tested forbromine indicating bromic acid ; and the third for chlorine by pre-cipitating with silver nitrate and digesting wit>h ammonia (0.998) ; ifa white Precipitate insoluble in boiling nitric acid is formed on addingnitric acid to the filtrate, it indicates that a chlorate was present.The original precipitate, which may contain cyanide, bromide, iodide,bromatc, iodate, ferrocyanide, and ferricyanide of silver, is carefullywashed and digested with ammonia (0*998).* This leaves undissolvedthe silver bromide, iodide, and ferrocyanide, which is carefullywashed and treated with hydrogen sulphide solution and a littlehydrochloric acid: after remora1 of the exeess of hydrogen sulphidethe solution is tested for hydroferrocyanic acid in the nsual way witha ferrosoferric salt, and the filtrate from the prussian blue precipitateis then examined for iodine and bromine with carbon bisulphide, &c.Into the ammoniacal soh tion containing the cyanide, chloride, bro-mate, iodate, and ferricyanide, an excess of sulphurous acid solution ispoured ; this precipitates the silver cyanide and chloride, and reducesthe other acids, precipitating them as bromide, iodide, and ferro-cyanide of silver.On treating the washed precipitate with ammonia(0.998) the three last are left undissolved and are tested in themanner described above, showing the presence in the original solutionof bromic, iodic, and hydroferricyanic acids. The silver chloride andcyanide dissolved by the ammonia are reprecipitated by nitric acid,and the precipitate divided into two parts ; one is treated with a littledilute hydrochloric acid and the solution tested for hydrocyanic acid,whilst the presence of chloride in the other is indicated b7 its leavingan insoluble residue when boiled with nitric acid.C.

There then reniains silver chloride, whichseparated and weighed gives the chlorine present ; the solution con-tains silver nitrate corresponding with the silver cyanide, and alsosilver sulphate corresponding with the silver thiocyanide. The sul-phuric acid is determined by precipitation with barium nitrate, andin the partially neutralised filtrate, the silver is determined by titra-tion. If a ferrocyanide is also present, it is precipitated by an acidferric salt free from chlorine, and in the filtrate the three acids aredetermined as before. If the titration with silver is made beforeremoving the ferrocyanide, an excess of silver must be added beforethe addition of the ferric salt used as indicator.H. B.Estimation of Hydrocyanic Acid. By R. A. CRIPPS (Phn~m. J.Trans. [ 3 ] , 2.3, 917-918).-1n the directions for the estimation ofhydrocyanic acid in the United States Pharmacopmia, it is stated that13.5 grams of dilute hydrocyanic acid mixed with magnesia, whentitrated, using potassium chromate as indicator, should require 50 C.C.standard silver nitrate, representing 2 per cent. absolute hydrocyanicacid. The author points out that this quantity would be correct pro-vided a double cyanide of magnesium and silver were formed and thecompletion of the formation indicated by the chromate. It happensthat, a magnesium silver cyanide, MgCyz,2AgCy, does exist, and canbe obtained in crystals by dissolving silver cyanide in magnesiumcyanide, but potassium chromate cannot be used as an indicator ofthe completion of its formation.The author is of opinion thereforethat 100" of standard silver nitrate would be required instead of50 c.c., and that the British Pharmacopmia process is preferable tothat recommended in the United States Pharmacopwia.D.

COWNLEY (Pharnz J.

A. LANALYTICAL CHEMlSTRY. 1175Use of Bromine in Testing for Alkaloi'ds. By C. L. BLOXAM(Chenz. News, 47, 215).--If the alkaloid be dissolved in dilute hydro-chloric acid, and bromine-water added drop by drop, the followingreactions are obtained :-Brucine gives a violet colour, strychnine thesame on boiling, narcotine a rose-pink, and the same with quinine.With excess of bromine, strychnine, brucine, and narcotine readily giveyellow precipitates, whilst quinine, morphine, and cinchonine are onlyprecipitated with difficulty or from strong so1ut)ions. If ammonia beadded to the quinine and bromine solution, the characteristic greencolour is produced.If the morphine solution containing excess ofbromine-water be boiled, zinc added and again boiled, cooled anddilute ammonia added, a pink colour is produced. H. B.Bromine as a Test for Strychnine. By H. JACKSON (Chern.News, 48, 11).-The author finds that acidifying with a few drops ofconcentrated sulphuric acid greatly intensifies and hastens the pro-duction of the violet coloration with bromine in solutions of strych-nine. A distinct rose-pink coloration is produced in a solution con-taining 3&,F of a grain of strychnine. The author suggests aplan for the estimation of strychnine, using a standard solution ofstrychnine and then comparing colours in a manner similar to theNesslerising method. D.A . L.Analysis of NuxVomica. Ey W. R. DUNSTAN and F. W. SHORT(Pharrn. J. Trans. [ 3 ] , 13, 1053--1055).-The authors have analysedsa;mples of nux vomica beans from different localities. The processemployed is substantially that described at p. 689 of this volume, thepercolate, however, is acidified with 5 per cent. sulphuric acid, and10 C.C. of it only are taken for the second agitation ; the liquid havingbeen rendered alkaline with ammonia, the extraction is effected bytwo successive treatments with 15 C.C. of chloroform. The beansvaried in size and appearance ; all the cotyledons were seven-reined ;the analytical results were as follow :-Percentage of Strychnine and Brucine.Bombay BombayVariety. Madras.

L.Picric Acid as a Test for Albumin and Sugar in Urine. By .G.JOHNSON (Pharm J. Trans. [3], l3,1015--1019).-To test for albumin,add to the urine either a small quantity of solid picric acid, or anequal volume of a saturated solution of picric acid, or pour some ofthe solution on the urine so a s to form a layer ; in all cases the presenceof albumin is indicated by the immediate appearance of a coagulum ;in the last case, the coagulum forms a horizontal ring at the junctionof the liquids. This coaguluin is soluble in alkalis ; if therefore theurine is very alkaline i t must be acidified before testing ; this precau-tion is seldom necessary, as the picric acid is sufficient to effect therequired neutralisation.This test is more delicate than the old nitricacid one. Any turbidity of the urine must be got rid of previouslyto testing with picric acid.To test for, and determine the amount of glucose in a saccharinesolution or urine, the author makes use of the reduction of picric topicramic acid by glucose in the presence of potash. This change, asis well known, is accompanied by a change of colour from yellow todeep red ; now the author has found by experiment that the depth ofthe red colour produced depends entirely on the amount of glucosepresent, and is, moreover, invariably proportionate to the dilution ofthe solution. Thus, if one solution contained a certain quantity ofsugar, and another solution contained four times as much, then thecolour produced by the latter, diluted to four times its own bulk, wouldbe of the same depth as the colour produced by the former.Thereforea certain colour-strength is settled upon as a standard, and all solu-tions are very carefully and accurately diluted down to this standard ;the dilution is conveniently conducted in a graduated vessel alongsideof which the tube containing the standard is attached; then thequantity of glucose in the standard, multiplied into the degree ofdilution, will give the quantity of glucose in the solution underexamination. The author's standard colour is that produced by aquarter-grain of sugar to the fluid ounce, and is thus obtained :-Afluid drachm of a solution of sugar containing 1 grain to the ounce, ismixed with half a drachm of potash solution (B.P.) and 10 minimsof a saturated solution of picric acid, and made up to 4 drachmswith distilled water.This mixture is now boiled for one minute,cooled, and, if necessary, made up to 4 drachms. The picramic coloiiris very fugitive, therefore the 4-grain colonr is imitated by the follow-ing mixture : all solutions are B.P. preparations, strong ferric chloridesolution (1 drachm), ammonium acetate solution (4 drachms), glacialacetic (4 drachms), distilled water ( 2 i ozs.), which produces a muchmore stable colour. All quantitative experiments with saccharinesolutions or urine, are conducted in the same way as the standard isproduced. It is not necessary to alter the quantity of potash, theamount of picric acid must however vary with the quantity of sugarpresent; it is always better to have a slight excess, as the yellowcolour does not interfere with the red.The colour is not affected bypure albumin ; the colouring-matter, however, of egg-albumin has TECHNICAL CHEMISTRY. 114’7reducinp action on picric acid : this colouring-matter is easily removedby filtration through animal charcoal. Results obtained by this processcompared with those by Pavy’s ammonio - cupric method, showrather lower figures; this the author attributes to something notsaccbarine reducing the copper solution, but not the picric acid ; andhe finds that normal urine contains two cupric-oxide-reducing sub-stances:-1, Those not destroyed by potash, such as uric acid, &c.2. Those destroyed by potash. Those of class 1 do not reduce picricacid, hence it happens that if the cnpric oxide reduction obtainedfrom a urine which has been boiled for some time with dilute potashbe deducted from the cupric oxide reduction effected by the originalurine, the reduction thus obtained is eqiial to that given by the picricacid with the original urine. This reducing substance only differsfrom glucose in not being fermentable by yeast; there are somesugars which behave in a similar manner, namely, sorbite and eucalin ;it is therefore very probable that this sacchardid ingredient of normalhuman urine may be a true sugar, although its identity with glucoseis incomplete. D. A. L.Dialysis of Putrescible Substances. By H. STRUVE (J. pr.Chew. [ Z 3, 27, 231--24!~).-The author recommends suspending abladder filled with the fluid to be dialysed in a saturated solution ofchloroform in water, or in pure ether, and details the results thusobtained in the case of white of egg, and of milk both cows’ and human.He finds that the whole of the albumin and soluble case’in, as well asall crystalline constituents, pass through the bladder, leaving behindthe cell-walls and the fat. He contends that these results show thedistinction between colloids and crystalloids to be without foundation.Use of Phosphoric Acid in Pettenkofer’s Reaction for BileAcids. By E. DRECHSEL (J. pr. Chew. [Z], 27, 424).--Thc failure inobtaining Pettenkofer’s reaction when phosphoric acid is used inplace of sulphuric acid is due to the employment of too large a quan-tity or too concentrated an acid. A few drops of a mixture of 5 vols.of commercial syrupy phosphoric acid with 1 vol. of water, should beused. A. J. G.0. H

TECHNICAL CHEMISTRY.T e c h n i c a l Chemistry.1147Marsh-gas Fermentation in the Mud of Ditches, Swamps,and Sewers. By H. TAPPEINER (Ber., 16, 1740--1744).-The fer-mentation produced by the addition of mud to a sterilised 1 per cent.solution of meat extract containing cotton wool and Nageli's salts,yields a gaseous mixture containing 48.05 per cent. CO, and SH, and51.68 per cent. of H.

Butyric and acetic acids were pro-duced in each case. The relative amonnts of COz and CH4, producedby the action of mud on meat extract alone, are in the ratio of1 : 3.1-3.6. Similar results aye obtained if vegetable albumin orpeptone is substituted for meat extract.Small quantities of thesebodies give rise to an evolution of gas which lasts for weeks.New Properties of Ferric Sulphate. By ROHART (C'ompt. wnd.,96, 1705--1708).--Ferric sulphate, as neutral as possible and freefrom any appreciable quantity of ferrous sulphate or ferric chloride,combines with animal and vegetable substances, precipitating themfrom solution, and forming definite and highly stable compounds,which undergo no alteration when exposed to air. A solution offerric sulphate of 50" B. containing 26 per cent. of ferric oxide, addedto urine in the proportion of 2 per cent., instantly precipitates urea,mucus, and urinary phosphates, and the urine thus treated undergoesno change on exposure to air.Similar results are obtained withsewage. Different parts of animals, and entire fish and small animals,when suspended for a few days in a solution containing 1 per cent. offerric sulphate, are rendered non-putrescible, and may be dried with-out undergoing change. There is actual combiiiation between theferric sulphate and the organic matter, the former app+ring to takethe place o€ some of the water contained in the latter. An adderweighing 59 grams was dried completely: it weighed 19 grams. Itwas then immersed for six days in the ferric sulphate solution, andagain dried; it now weighed25 grams, or an increase of 32 per cent.on its weight in the dry state, The ferric sulphate which thus com-bines with the organic matter cannot be dissolved out by hydrochloricacid, and is not decomposed by boiling with barium chloride solution.Meat treated with this reagent retains its red colour, but becomes sohard that it can scarcely be scratched with the nail.Experimentswith eggs show that the ferric sulphate solution penetrates into theorganisms by endosmosis. C. H. B.By J.FoRsTER (Rer., 16, 1754--1759).-The author considers the use ofboric acid for preserving articles of food to be a questionable practice.Boric acid increases the secretion of bile and the amount, of albu-minous matters excreted. w. c. w.w. c. w.Employment of Boric Acid for Preserving Food.Manufacture of Tartaric Acid. By L. H. FRIEDBURG (Pha~m.J. Trans. [3], 13, 992--10UO).-In the process described, the finelypowdered argol, sablons, or lees, is added gradually to milk of limeand boiled with constant stirring for two hours ; in this way potassiumhydroxide and calcium tartrate are formed, and the nitrogenousorganic matter decomposed, ammonia going of€ with the steam.When the boiling is complete, the mass is diluted, and the potashneutralised with hydrochloric or sulphuric acid, more cold water isnow added, and the whole well stirred for some considerable time (allnight).The liquor containing potassium salts, &c., is filtered off,concentrate<!, and otherwise made marketable. The impure calciuTECIINICXL CHEMISTRY. 1179tartrate, which is very prone to putrefaction, is speedily decomposedwith sulphuric acid in the cold, methyl-violet paper being used to in-dicate when the required quantity of sulphuric acid has been added.From this brown solution, the tartaric acid is carefully reprecipitatedas cdcinm tartrate, lime being used at first;, but chalk towards theend, using litmus as indicator of the complete neutralisation.Theprecipitate is filtered and slightly washed ; the calcium tartrate formslight greenish-yellow crystals, which may be kept for any length oftime without decomposing. This is also decomposed by sulphuricacid in the cold, again wing methyl-violet paper. The precipitatedgypsum is filtered off and well washed, and the tartaric acid solutionevaporated a t 80" until the gypsum in solution is deposited; it isthen run into crystallising boxes.The brown crystals thus obtainedare dissolved to a liquor density of 25" R., treated with animal charcoal(which has been washed with hydrochloric acid), filtered, evaporatedto 39" to 40" B., and either run into lead boxes to crystallise slowly,or delivered into a tank fitted with a stirrer, where it is stirred f o rseveral hours, and n crop of small crystals formed directly. Thecrystals are washed and dried in centrifugals, steam being used forwashing. The liquid from the first crystallisation deposits another cropof white crystals ; it then becomes brown mother-liquor, from whichcrops of crystals are obtained until the predomination of sulphuricacid and other impurities does not allow further crystallisation. Theyare then diluted, the greater part of sulphuric acid removed by lime ;and iron and aliiminium phosphates gc.t rid of by further treatmentwith lime, when acid calcium tartrate is left in solution ; this is filteredhot, and decomposed by sulphuric acid, when it yields a very puresolution of tartaric acid.For the preparation of potassium hydrogen tartrate, the acid solu-tion is divided into two equal parts, the one is neuhalised with potas-sium carbonate, the two are then mixed, and the potassium hydrogentartrate is precipitated.D. A. L.Chemistry of Fish. By W. 0. ATWATER (Bey., 16, 1839-1846).-The author gives the results of the analyses of t'he flesh of 64kinds of fresh and preserved fish, which are used for food. w. c. w.Fermentation of Bread. By MOUSSETTE (Cornpt.rend., 96,1865).-The liquid obtained by condensing the vapours from a breadoven contained 1.6 per cent. by volume of alcohol, and 0.06 per cent.by weight of acetic acid, together with a small quantity of ferric ace-tate (from the walls of the oven), and a very small quantity of ammo-nia. This experiment, which was made in 1854, proves that alcohol isone of the products of the fermentation of bread (see next Abstract).C. H. B.Fermentation of Bread. By G. CHICANDARD (Compt. rend., 96,le585-l588).-1t is generally supposed that in the fermentation offlour paste the starch is converted into maltose under the influence ofdiastases existing in the flour, the maltose being eventually convertedinto glucoses, which undergo alcoholic fermentation.But the dias1180 ABSTRACTS OF CHEMICAL PAPERS.tases existing in flour act only on starch altered by heat, and have noaction on unaltered starch ; moreover, the presence of alcohol in thepaste has never been proved. The author has analysed filtered in-fusions of floiir, paste with leaven, paste with yeast, and bread, andhe finds that there is no soluble starch in flour, o r in the two pastes,but that a considerable quantity exists in bread. The four substancescontain equivalent qnantities of glucose, from which it follows that theglucose originally existing in the flour is not decomposed. Flour con-tains albumin which is coagulated by heat and is precipitated by nitricacid and by potassium ferrocyanide and acetic acid. The two pastescontain no albumin coagulable by heat, but they contain albumlno'idsprecipitable by nitric acid and by potassium ferrocynnide and aceticacid, together with peptones not precipitated by these reagents, butprecipitated by tannin.Bread contains no albuminoids, but it containspeptones precipitated by tannin, corrosive sublimate, &c. Microscopicexamination shows that the paste with leaven contains no smccharo-wyres, and that the cells of sacchnronayces cerevisice introduced into thepaste with yeast gradually diminish in number. Both pastes con-tain a number of moving microbes, of very varying length, whichappear to be bacteria. These bacteria develop very rapidly in pastewith yeast, and they can be culhivated in water holding yeast in sus-pension, from which it would appear that yeast i s favourable to theirdevelopment.The gas evolved during fermentation is a mixture ofcarbonic anhydride, hydrogen, and nitrogen, and is analogous in com-position to the gas evolved in the putrefaction of albuminoids.The author concludes that the fermentation 09 bread is not due to asaccharomyces, and that it consists, not in hydration of the starch fol-lowed by alcoholic fermentation, b u t consists in the conversion of aportion of the insoluble albuminoids of the gluten into soluble albumi-no'itls, and eventually into peptones. The starch is modified by the heatonly, a considerable quantity of soluble starch and a small quantity ofdextrin being formed. The agent of fermentation is a bacteriumwhich develops normally in paste, the development being acceleratedby the presence of yeast.These remarks do not apply to the English process, in which fer-mentation is produced by a mixture of yeast with potato-starch alteredby heat. C. H. B.Italian Petroleums. By B. PORRO (Gazzetta, 13, 77--85).-Theauthor has examined four specimens of petroleum found in Italy a tPetralio Montanaro near Piacenza, a t Rivanazzuno near Vogheru, a tTocco Casanria, and a t San Giovanni Incsrico.The first had a sp. gr. of 0.7849 a t 15", and when distilled gave44.7 per cent. light petroleum ; 19% distilling between 127" and 150" ;22 between 150" and 203"; 14.4 above 203", and left 6.9 per cent.residue.The second of sp. gr. 0.9132, gave 22 distilling below 230'; 33between 2.30" and 270' ; 37 above 270", and 7.7 residue.The third and fourth of sp. gr. 0.951 and 0.974, gave respectively63.5 and 69.6 per cent. oil ; 32.2 and 28.3 of pitch, and about 12 and20 of gas.
