''The constitnents of the seeds of Casimiroa edulis." By Frederick Belding Power and Thomas Callan.The material employed for this investigation consisted of the fresh seeds of Casimiroa edulis, La Llave and Lejarza (Nat. Ord. Rutaceae), which were obtained directly from Mexico. The kernels of the seed, representing about, four-fifths of the weight of the entire rnat.erial, gave abundant reactions for an alkaloid, and mere found to contain an enzyme which slowic hydrolysed amygdalin. 258 An alcoholic extract of the kernels, when distilled in a current of stlearn, yielded a small amount of a pale yellow essential oil, which possessed an aromatic odour and the following constants : Dm 0.9574; a, -2O25‘ in a 25 mm. tube. From the portion of the extract which was kolarble in water there were isolated: (I) a new alkaloid, casimirointq, C24HB,,0,X’, (m.p. 196-197O ), which on heating with alkalis undergoes hydrolysis with the elimination of carbon dioxide, yielding a new base, casimiroitine, C,,H,O,N, (m. p. 171O); (2) a new alka!oid, casimiroedine, C1,H2405K,(m. p. 322-223O) ; (3) benzaic a.cid, with apparently a trace of sa.licylic acid. The aqueous liquid contained, furthermore, T, quantity of sugar, which yielded d-pheoylglucosazone (m. p. 205-207c). The portion of the extract which was insoluble in water consisted of a soft, oily resin, from which the following compounds were isolated : (1) sitosterol, CZ7H,,0; (2) ipuranol, C,,H,,O,(OH), ; (3) a mixture of fatty acids; (4) a new !actone, casimirolid, C,,EL,O, (m. p. 229-230°), which yields a new hydroxy-acid, designated as casimiroic acid, C,,H,80,(OH)*C0,H (m.p. 207*), of which the silver salt, methyl ester, and acetgl derivative were pre- pared ;(5) a. yellow, phenolic substance.

The hypnotic or toxic properties attribnted to Cursirniron seed could not be confirmed by physiological tests. *268. ‘-Preparation of the betaine of tryptophan and its identity with the alkaloid hypaphorine.” By Bieter van Romburgh and George Barger. The betaiiie C,,H,,O,N, has been obtained by the methylation of tryptophan, and has been proved to be identical with t-he naturally occurring a.lkaloid hypaphorine. The intermediate compound, C15J3,10J21, which is formed is the quaternary iodide of methyl a-trimet /I ylctm irzo-P-indoleprop,io?irit e, glistening plates, m.p. 197O. “269. ‘‘ P-2-Methoxynaphthylpropionicacid and methoxyperinaphth- hydrindone.” By GCeorge Barger and Walter William Starling. Experiments were carried out with the object of adding a third six-membered ring to naphthalene by introducing a chain of three carbon atoms joining two peh-positions (compare Sachs and Brigl, Rer., 1911, 44, 2091). The following new substances were described : P-2-ntet~o~naphthyEacrylicacid, CH,*O=C,,R,*CH:CH*C02H, m. p. I GOo ; B-2-met~oxyrraphthy~~ro~7i~~ti~acid, C~3*O*C,,H,~CH,*CH,.C0,’H, 259 m. p. 128?; and mcthoa.yperinapl~th-~y~~~?~’d~~~,C14H,,Q,, deep yellow crystals, b. p. 210°j12 mm.? m. p. 13Sc. ”270. Some derivatives of 4(or 5)-methylglyoxaline.” By Arthur James Ewins.3y Heating 4(or 5)-methylglyoxaline with formaldehyde to 120°, an 3 dditii-e prcduct, 4(or 5)-met hy Z-5 (or 4)-hydro~ym e thylglyoxaline, m. p. 13S0, is formed. When treated with phosphoryl chloride, this compound yields 4(or 5)-methyl-5(or4)-chloromethylgEyoxaZine. The latter can be converted into 4(or fj)-methyZ-5(or4)-cyanomethyZgly-ox~line,m. p. 163--164O, which on reduction yields 4(or 5)-methyZ-5(or 4)-fl-aminoethylgiyozaEiney a new base which was found to be physiologically active, having a marked vaso-dilator effect. By the action of ammonia and methylamine respectively on 4(or 5)-rnethyl-Z(or4)-chlorornethylglyoxaiine were obtained 4(or 5)-methyG5(or 4)-aminomethyl~2yoxnline and 4ior 5)-methyl-5(or4)-methyZaminomet7~ylgl~o~alin~.These coiiipmnds were, however, physi~logically inactive.“271. Studies In the camphane series. Part XXX. Constitution of pernitrosocamphor (camph enylnitroamine) .” By Martin Onslow Forster, John Robert Trotter, and Jacob Weintroube. From experiments xith pernitrosocamphor and its potassium derivative, the authors mre led to put forwt.a.rcl EBW formulz for these corcporznds. cb272. Dihydroxydihydrindamine and its resolution into optically active components.” By William Jackson Pope and John Read. Improved methods were described for the preparation of bromo-hydroxyhydrindene, CGH4<gg?oH)>CHBr, and its conversion into dihydrozydihycirindarnilze iI> ‘and 1-kydroxy-2-hydrindamine (11):(C,H4<CH?OH;>CH)?N €3 CsH4<g&~CH *w?CH -(1.1 (11.)The resohtion of dihydroxydihydrindamine into its optically active component5 by meantj of d-camphor-8-snlphonic acid was described.273. Studies in phototropy and thermotropy. Part 11. Naphthylideneamines.” By Alfred Senier and Rosalind Clarke. The Schiff’s bases obtained by the condensation of 2-hydrouy-a-naphthaidehyde with various aromatic amines have been studied in order to see if these compounds, which contain the hydroxyl radicle in the ortho-position with respect to the group CHXR in the naphthalene ring, exhibit phototropy or thermotropy in the same manner as previous experience had shown to be the case with analogous benzene derivatives.The naphthylideneamines in question are obtained by the interaction of 2-hydroxy-a-naphthddehyde with the following amines: 0-, m-, and p-chloroasilines, 0-, m-, and p-bromoanilines, m-nitromiline, 0-, nt-, and paminophenols, 0-, m-,and p-anisidines, 0-, m-, and p-aminobenzoic acids, 04,m-4-, and pxylidines, and $-cumidine. None of these bases proved to be phototropic, but all exhibit thermotropy. 274. ‘‘ The stability of the double oxalates of sodium and nickel, and sodium and cobalt.” By John Wallis Dodgson. On boiling nickel oxalate, NiC20,,2&0, with an approximately 2X-solution of sodium carbonate, a green solution is obtained; when this is filtered frara the residue, and allowed to remain for about twenty-four hours. peer, crystals separate, which consist of the double oxalate of sodium and nickel, with but a small amount of impurity.The green solution cannot be crystdlised by evaporation aided by heat, as the salt is partly decomposed on heating with water or with sodium carbonate solution, forming a gale green precipitate, but leaving a solution still green in colour. The green solution is also obtained when sodium oxalate and nickel oxalate are boiled together with water, and also when nickel carbonate is boiled with sodium oxalate solution, but in the latter case crystals do not form easily. Three specimens of the crystalline compound were prepared, one (a) by boiling 20 grams of nickel oxalate with 100 C.C. of a 2N-solution of sodium carbonate, another (6) by boiling 15 grams of nickel oxalate with 100 C.C. of a 4n’-solution of sodium carbonate, and a third (c) by boiling sodium oxalate and nickel oxalate in molecular proportions with water.A green solution was obtained in each case; it was fihered, and allowed to remain for a few days? when the crystals selmated, and were washed several times with cold water and dried in the air. On analysis: 261 (a)Found Ni=13*63; Na=10'41; C20,=41.18; HdO=34*73.* (b) ,, Ni=13*62; Na=10*83; C20,=41.18; H20=34+37.* (c) ,, Ni=13-'77; Na=10*79; C,O,=41.43; H:;O=34+01.* Na2C204,NiC20,,8H20 requires Ni =13-82;Ka =10-83;'2-04=41.44; H,O=33.91 per cent. The results agree sufficientiy closely with one another to warrant the conclusion that the same compound is formed in each case, and that its compwition is properly expressed by the fornula N~C,0,,KiC20,,8E,0.In order to test the effect of a large excess of carbonate, 100 C.C. of a 4N-solution of sodium carbonate were boiled with three grams of nickel oxalate; a pale green solution was obtained, from which no crystals separated after five days; later sodium carbonate crystallised out, leaving the solution still green. This result agrees with that obtained on boiling the double oxalate with a solution of sodium carbonate. The reaction which takes place is obviously a balanced reaction, and may be represented by the equation: Na,CC\, +BNiC,O, Na2C20,,NiC,0, +NiCO,, the actual conditions of equilibrium depending on the relatf Te masses of the sodium carbonate and nickel oxala.te reacting. As, however, the most interesting case is that of the action of a 2S-solution of sodium carbonate, 5 grams of oicliel oxalate wcre boiled with 50 C.C. of 2N-sodium carbonate, the liquid 5ltered while hot.the residue thoroughly washed with successive quantities of cold mater, and the filtrate and washings di!uted to half a litre. Analysis showed that this contained 2.2 gram of C,O, and 0.245 gram of nickel; these amounts are 87-5 per cent. of the C204, and 15.2 per cent. of the nickel in the nickel osa!ate faken. The residue left on the filter was found to contain oxalate. Cobalt oxalate, CoC20,,2H2O, is decomposed in a similar manner, but the amount of double oxalate produced is not so great.Five grams of cobalt oxalate were boiled with 50 C.C. of 2N-sodium carbonate, and filtered and washed. The filtrate was found ta contain 2.37 grams of C204 and 0-117 gram of cobalt; in this case practically all the C,04 in the original osahte enters into solution, but only 7.3 per cent. of the cobalt, as compared with 15 per cent. of the nickel. The residue consisted entirely of carbonate. The double oxalate of cobdt and sodium is easily prepared by boiling together cobalt oxalate and sodium nxalate with water. The pink solution deposits crystals on keeping, which on analysis gave the following result: '' By difference. 262 Found: GO= 1389 : C,0,=41.18. hTa,C,0,,CoC20,,8H,0 requires Co= 13.88; C,O,= 41-41 per cent.It is therefore obvious that neither nickel oxalate nor cobalt oxalate can be compktely converted into carbonate I]? the action of a sodium carboxEbkplution, and that in each case a soluble double oxalate is Iormed, having the composition given by the formulze already deduced, this double salt being stable in the presence of excess of sodium oxslate. 275. “The lower limit of inflammation of mixtures of the paraffin hydrocarbons with air.” By Maurice John Burgess and Richard Vernolr Wheeler. The conditions wider which self-propagation of flame can take place in mixtma of inflammable gases and air were discussed. The authors find that the smallest quantity of pure methane that will enable self-propagation of flame to take place when a source of heat is introduced into a mixture of it with air is 5.6 per cent.by volume of the mixture. That is to say, the “ lower-limit. mixture ” contains 5.6 per cent. of methane. It was shown that for the paraffi hydrocarbons the lower limit of inflammation varies inversely ds the calorific value of the gas. Thus, if L=the proportion of the paraffin hydrocarbon necessary to form a lower-limit mixture, and C=its calorific value. L =.f(1/c) ;or, say. L =kl /c, where i% is a csmstazih. Using methane 2.z the standard to obtain the value of k, the observed and calcniated values of L are as follon-s: Gas. L ob3erved. L ealculeteli.

Continuing their studies on the cyclic condensation of derivatives of 2:2/-ditolyl, which have Been shown to iead to the formation of phenmthrene (this VOI., p. 92), the authors have found that 2 :2’-dialdehydodiphenyl is converted by the action of concentrated potassium liplroside solution into o -7tydroxg-2-me thgId iphenyf-2’-carboxyiic acid, m. p. 146O, from which an E-lnctone? m. p. 132O, is obtained by heating it at llOo. 263 2 :2‘-j’)iloiyZ-oo!-dicart oxylonitrile undergces coildensation under the infliience of sodium ethoxide, with formation of l-irnh70-2-cymo-3 :Ei-dibenz0-~3:6-cycloh.eptadiene,m.p. 189O. This substance is hydrolysed by sulphuric acid, with formation of 1-imino-3:5-dibenzo-AS ~~-cycloheplaiEiene-2-car~oxylicacid, m. p. 180°, which yields m.3 :Ei-dib~ny’o-03:5-~ycIohe~tad~erc-l-one,p. 78-79O. by further hydrolysis with dilute acid. 277. ‘(Syntheses with phenol derivatives containing a mobile nitro-group. Part V. Quinoneimides, asymmetric quaternary ammonium compounds, and asymmetric carbinols (continued). ” By Raphael Meldola and Harold Kuntzen. The authors gave further proof of the general applicability of their method of synthesising dinitroiminazolium compounds, imin- azolones, and irninazolols. A series of new compounds wa described, in which the radicles X and Y in the formulze given below had been varied: In the new series X represented phenyl, panisyl, p-chloropheny; and benzyl; P=ethyi and isobutyl, and Z=methyl. A further consideration of possible formulae for the quinoneimidonium com-pounds led the authors to maintain the correctness of their original view as expressed by the formuh adopted.It was pointed out that the quinquevalent nitrogen atom in these compounds was comparable with that contained in compounds of the oxyammonium type, O:N(R),, the highly acid quinonoid radicle representing the oxygen atom. Independent evidence of the existence of such quinoneimidonium compouqds had been obtained in the course of a further study of the product of the extreme methylation of isopicramic alcid (Proc..1910, 26, 232), and the authors stated that this research was in progress. 278. ‘‘ Isomeric acetaldehydephenylhydrazones.” By Erngst Graham Laws and Nevi1 Vincent Sidgwick. Loclcemann and Liesche’s work on this subject hm been repeated. and confirmed in more detail. The hydraone was prepa.red by the interaction of acetaldehpde and phenylhydrazine in aqueous alcohol, 264 The product is a, mixture of the two isomeridea. The a-form, m p. 98*6O, is obtained by recrystallisation from alkaline aqueous alcohol, and the /3, m. p. 56’6O, by recrystallieation from acidified aqueous alcohol. Aqueous and gaseous alkalis and acids cause the isomeric change without the hydrazone passing into solution, and without any apparent change in the crystals t-hemselves. The freezing-point CUL~~has been obtained, and shows that the two iaomerides form a continuous series of mixed crystals (solid solutions). The crystals of the two forms appear to be identical, and they have the same density.The influence of a solvent is to give an equilibrium mixture containing about’ i5 per cent. of the a-fcrm. The hydrazone can be distilled in a vacuum, and the isorrerides pass over at temperatures 100G apart. The peculiarity of the isomerism must be connected with the sma.11 difference in the relative stability or“ the two forms. On the other hand, there is no doubt that the a-modi€cation is more stable in the presence of alkali, and the P-in the presence of acid, and that a trace of alkali or acid can bring about a change proceeding through a mass of crystals without their passing into solution. It therefore follows that there is it difference between crystals in ccntact with acid and crystals in contact with alkali.This can only come about by adsorption of acid or slk2li into the crystals, which causes a difference in energy ge?t_er thail thc: difference between the two absolutely pure forms. 279. ‘‘ Nitrites of the alkylammonium series. Part IV. Triethyl-ammonium nitrite and its decomposition and sublimation by heat.” By Prafulla Chandra Ray and Jitendra Nath Rakshit. Triethylammonium nitrite is obtained by the interaction of trietbylamine hydrochloride and silver nitrite in aqueous solution and evaporation of the filtrate in a vacaum orer sulphuric acid. The salt crystallises in pale yellow tabIet,s and prisms.When heated it dec6mposes into triethylamine, alcohol, and ether, nitric oxide, nitrous oxide, and nitrogen being evolved; at the same time a portion of it sublimes unchanged. 280. The formation of dichlorocarbamide and its behaviour towards amines.” By Rasik La1 Datta. In the preparation of dichlorocarbamide, Chattaway (Proc. Roy. Soc., 1908, 81,381) ascribed the small yield which he obtained to the hydrolysis of the compound by the acid liberated in the reaction. It has now been found that: during the formation of 265 dichlorocarbamide, carbamide hydrochloride is produced, which diminishes the yield, being ihelf incapable of chlorination.The action of bromine on carbamide has been studied, and the results se0m to point to the formation of dibromocarbamide in solution. The behaviour of. amines with dichlorocarbamide has also been investigated, the result being the formation of chloroamines, wit*h or without the evolution of gas. 281. (‘Synthetical experiments in the group of the isoquinoline alkaloids. Part 11. The constitution of the condensation products of cotarnine and the condensation af cotarnine with aliphatic and aromatic nitro-compounds.” By Edward Hope and Robert Robinson. An account was given of the condensation of cotarnine with nitromethane, and with a number of derivatives of nitrotoluene : 0-and p-nitrotoluene condense in the presence of sodium ethoxide, whilst nitromethane, di- and tri-nitrotoluenes, and also trinitroxylene and trinitromesitylene condense in the absence of any agent.282. “The synthesis of derivatives of thioxanthone. Part IV. Synthesis from aromatic sulphinic acids.’’ By Harold Christopher and Samuel Smiles. It was shown that derivatives of thioxanthone may be obtained by heating together a sulphinic acid with a m-hydroxy- or amino- benzoic acid. A few typical examples of this synthetical method were given. From benzenesulphinic acid and m-aminobenzoic acid 2-aminothioxanthone was obtained, whilst o-and p-toluenesulphinic acids with m-amino-or hydroxy-benzoic acid yielded the corre-sponding amino- or hydroxy-thioxanthones.Hydroxythioxanthone, prepasred by mother method, mas also investigated. 283. LL Komppa’s synthesis of camphoric acid.” By Gustave Louis Blanc and Jocelyn Field Thorpe. The authors find that when methyl diketoca.mphora,te is hydro- lysed by very dilute alkali, that is, under conditions comparable with Chose used by Komppa in his synthesis of camphoric acid, the methyl group remains attached to carbon. Their criticism of this synthesis is therefore baseless. 66284. The electrochemistry of solutions in acetone. Part I.” By Alexander Roshdestwensky and William Cndmore XcCullagh Lewis. The object of the experiments was to find if the Kernst expres- sions for the electromotive forces of concentration cells hold good in acetone solution.Conductivity measurements were carried out in the case of lithium nitrate and silver nitrate in order to deter- mine the ionic concentration values required for the calculation of the cell Ag I AgISO,:AgKO, I Ag, which includes in its simple formc, c, a liquid iliquid potential difference? and also for the calculation of E.M.F.’s when aktempts are made to remove the liquidlliquid potential difference. The results obtained on comparing calculated and found values support the view that the simple wmotic formulae are applicable. 286. Chlorination of a-naphthol by acetylchloroamino-2:4-di-chlorobenzene.” By Harold King. With the exception of Kast’s (Ber., 1911, 44, 1337) recent pre- paxation of 4-chloro-a-naphthol by the use of sulphuryl chloride, the four known monochlorea-naphthols have only been obtained by indirect methods.In investigating the direct chlorination of a-naphthol, the author has used the method described by Orbn and King (Trans.,1911, 99, 1185). The naphthol is; treated in glacial acetic acid solution with a molecular proportion of ~etylchloroamincl2:4-dichloro benzene and 1 100th of a gram-molecular proportion of hydrochloric acid, whereby the concentration of the chlorine set free is kept at a low value. The chlorination is rapid, and unaccompanied by oxid* tion. The diluted acetic acid solution is extracted with chloroform, and the latter removed by a current of warm air. The chlorinated product is separated from the accompanying dichloroacetanilide by extraction with a 2 per cent.sodium hydroxide solution, and a single crystallisation from light petroleum (b. p. 60-85O) giveg a 40 to 50 per cent. yield of almost pure 4-chlorc~a-naphthol. The exceedingly soluble residue A, recovered from the petroleum mother liquor, corresponds in melting point and properties with the so-called monochloronaphthol of Claus and Oehler (Bey., 1882, 15, 312), Cleve (Ber., 1588, 21,831), and Kalle & Co. (D.R.-P. 167458).By fractional precipitation from alkaline solution by dilute mineral acid, a very partial separation into substances of different acidity takes place. [CZeve (Zoc. cit.) could obtain no pure product in this 267 way.] Nevertheless, the first 25 per cent.precipitated when recrystallised from dilute acetic acid yields hexagonal, scaly crystals of a-naphthol. 2 :4-Dichloro-a-naphthoi, crystallising in needles, cau be obtained in quantity from A by repeated crystallisation from dilute acetic acid containing 10 to 20 per cent. of water. No indication of the presence of other monochioro-a-naphthols in the mixture was observed, and hence, if present, they must be very small in amount. It is seen, therefore, that the composit,ion of the initial chlorinated product approximates to 50 per cent. of 4chloro-a-naphthol, 30 per cent. of dichlorea-naphthol, and 20 per cent. of a-naphthol, the two latter obviously being present in equimolecular proportions. The determination of the meltingpoint curve for mixtures of a-naphthol and dichlorea-naphthoi sfforded additional evidence that the soluble residue A consisted of equimolecular proportions of a-naphthol and dichloro-a-naphthol, with a very small quantity of 4-chloro-a-nap h thol.4-Chlor*a-naphthyi benzoate, CloH,C1*OBz (m. p. 99-looo ; Autenrieth end Miihlinghatis, Ber., 1907, 40, 748, give 1OO-1Glo), was obtained by benzoylation of 4-chloro-a-naphthol. It is readily soluble in all the ordinary organic solvents, except light petroleum. (Found, C1= 1246. Calc.. C1= 12-55 per cent.) OH /\/\Br.4-Ch207~2 -b1.0 nzo-a-wphthol,I I I \/\/t :1 By bromination of 4-chloro-a-naphthol in acetic acid solution, 4-citloro-2-bromo-a-r~ap37ttholwas obtained.It crystallises from benzene in lustrous, white needles, melting at 94-95O. It is very readily soluble in the common organic solvents. From acetic acid it separates in glassy prisms, containing acetic acid, which become opaque, and disintegrate on the water-bath: 0.1990 gave 0.2559 AgC1iAgBr. C1+ Br =44.81. CloH,OCIBr requires C1+ Br =44.82 per cent. Its constitution ww proved by oxidation with fuming nitric acid, whereby 2-bromoca-naphthaquinoneand Liebermann and Schloe berg's 8-dinaphthyl-a-diquinone(Ber., 1899, 32,548) were obtained. 4-Chloro-2-bromo-a-naphtholresembles 2 :4-dichlore and 2 :4di-bromo-a-naphthol in its behaviour towards alkalis. On expoeure of its solution in alkalis to sunlight, it is quantitatively converted into a deep blue, insoluble substance, which still contains bromine.The fact that the ortho-bromine atom is not displaced is not in 268 harmony with Bruncke's formula (Diss., Msrburg, 1903) for the corresponding compound obtained from dibromGa-naphthol : 00 Preparation of 2 :4-Dichloro-a-mphthot.-The employment of two molecular proportions of acetylchloroamino-2 :4-dichlorobenzene to one of a-naphthol serves as a quantitative method of obtaining dichloma-ndphthol free from tri- and penta-chloroketonaphthalenes which are formed when a current of chlorine is used for the chlorination.
