Of the following papers, those marked * mere read : “1. “The alkaloids of ergot, Part 11.” By George Barger and Arthur James Ewins. Ergotoxine (Barger and Cam, Frans., 1907, 91, 337) has now been shown to possess a carboxyl group; ergotinine, its anhydride, is probably a lactone. When ergotiuine is warmed with a dilute solution of phosphoric acid in absolute alcohol, the crystalline pho8phate of ergotoxhe ethyl ester, C3,H,o0,N,*C0,Et,H,PO~, is formed. This new base is amorphous; it differs from ergotoxine in being insoluble in dilute sodium hydroxide, and in yielding a series of salts having a different crystalline form from that of the corresponding ergotoxine salts.It is probable that the ester is also formed to some extent when ergotiuine and ergotoxine are heated with alcohol in the abseuce o€ acids. The fall of optical rotation of alcoholic ergotinine solutions has been examined. On destructive distillation, both of ergotinine and of ergotoxine, a small quantity of a crystalline sublimate is formed, which has been identified as isobutyrylformnmide, CHBle,*CO*CO*NH2; a new synthesis of this substance was described. 3 "2. *'The constituents of colocynth." By Frederick Belding Power and Charles Watson Moore. The material employed in this investigation was Turkish colocynth, consisting of the dried, peeled fruit of Citrzcllus Colocynthis, Schrader.The pulp of the fruit represented 24.4 per cent. of the whole. Au alcoholic extract of the pulp, on distillation with steam, yielded a small amount of an essential oil. From the portion of the extract which was soluble in water there were isolated a new dihydric alcohol, C,,H,,O,(OH), (m.p. 285-290°), designated as citrullol, and an amorphous, alkaloidal principle, which possesses strongly purgative properties. The aqueow liquid contained, furthermore, a quantity of inorganic material, a little sugar, and a very small amount of an amorphous, glucosidic substance. The portion of the alcoholic extract which was insoluble in water consisted chiefly of resinous material, but from it there were isolated a considerable quantity of a-elaterin (m.p. 232' ; [a], -68*9O) ; small amounts of hentriacontace, C31H64,and a phytosterol, C,7H,,0 (m. p. 160-1 62", optically inactive) ;a mixture of fatty acids, and a little of the above- mentioned alkaloidal principle. None of the constituents of the resin were glucosidic, but the portions extracted by ether and chloroform possessed purgative properties. No evidence could be obtained of the presence of p-elaterin. The seeds of the colocynth, which represented 75.5 per cent. of the entire peeled fruit, contoined traces of an alkaloidal principle, a small amount of an enzyme, and yielded 12-73 per cent. of fatty oil. From the latter there was isolated a small amount of a phytosterol, C,,H,,O (m.p.158-160'; [.ID +8.1'). The results of the present investigation have led to the conclusion that the so-called "colocgnthin " and "colocynthitin," which have previously been recorded as constituents of colocynth, consisted of mixtures of a very indefinite character. "3. '* Organic derivatives of silicon. Part XII. Dibenzylethyl-propylsilicane and sulyhonic acids derived from it." By Frederick Challenger and Frederic Stanley Kipping. With the object of obtaining an optically active compound contain- ing only one asymmetric silicon atom, the authors have prepared dibenzyllethylpropylsilicane, SiEtPr(CH,Ph),, by the interaction of benzylethylpropylsilicjd chloride and magnesium benzpl chloride ; and also more conveniently, by the interaction of dibenzylethylsilicyl chloride and magnesium propyl bromide.It is a colourless liquid, boiling at 262-265’/90 mm. The dl-monosulphonic acid, CH2Ph*SiEtPr.CH,.C,H4-S0,H, is pr6duced together with a disulzhonic acid, probably SiE tPr(CH,-C,H,*SO,H).,, when the silicohydrocarbon is treated with chlorosulphonic acid in chloroform solution. The separation of these acids is accomplished with the aid of their strychnine or 2-menthylamine salts. The resolution of the dl-monosulphonic acid has been effected, and the details will be communicated later. *4. “Formation of heterocyclic compounds. Part 11. Action of bases on the act’-dibromo-derivatives of certain dicarboxylic acids.” By Henry Rondel Le Sueur and Paul Haas.cis-Tetrahydrofuran-2 :5-dicarboxylic acid and muconic acid are formed by the interaction of alcoholic potassium hydroxide and aa’-dibromoadipic acid, m. p. 192-1 93’. Ethyl 1-phenylpyrrolidine-2 :5-dicarboxylate is the main product formed on heating together diethyl- aniline and ethyl aa’-dibromoadipate ; ethyl muconate is also formed in small amount, and during the course of the reaction a considerable quantity of ethyl bromide is evolved. The action of aniline and of ethylaniline on ethyl aa’-dibromo-succinate and of aniline on ethyl act’-dibromosebacate has been investi- gated, but in these cases no cyclic compound analogous to those meutioned above is produced. 5. The triazo-group. Part XI. Substituted triazomalonic and phenyltriazoacetic acids.” By Martin Onslow Forster and Robert Miiller.With the purpose of observing further the effect of environment on the behaviour of the triazo-group, the properties of substituted triazo- malonic’ acids have been studied. Methy ltriazomalonic, eth yltriozomalonic, and phenyltriaxomalonicc acids with their esters and amides have been prepared, and also the ethyl ester and amide of bistriaxomalonic acid, and the substances subjected to comparison with the corresponding derivatives of triazo- acetic and phenyltriazoacetic acids. 6. ‘(Iodobenzenemonosulphonic acids. Part 11. Esters and salts of di-and tri-iodobenzenesulphonic acids.” By Mary Boyle. Ethyl and methyl esters of 3 :5-, 3 :5-, 2 :4,and 3 :4-di-ioclo-benzenesulphonic, and of 3 :4 :5-, 2 :4 :5-, and 2 :3 :5-tri-iodobenzene- 5 sdphonic acids have been prepared and studied.The accumulation of iodine in the nucleus considerably reduces the stability of the sulphonic ester, the tri-iodo-derivatives being readily hydrolysed by water and by alcohol. The sodium, potassium, and arnmonizcm salts of 2 :4-and 3 :5-di-iodo- and of 3 :4:5-,2 :4 :5-, and 2 :3 :5-tri-iodobenzenesulphonic acids have been prepared and investigated with regard to water of crystallisation and to solubility. Experiments on the electrical conductivities of the acids have also been carried out, the results of mhicb, however, will be communicated later, 7. ‘‘The absorption spectra of naphthalene and of tetramethyl-naphthalene.” By Annie Homer and John Edward Purvis.The absorption curves for both iV/lOOO- and itT/lO-soIutions of the hydrocarbon, C,,H,, (Trans., 1908, 93,1319), are similar to the curves for naphthalene. They confirm the previous suggestion that the hydrocarbon is a tetramethylnaphthalene. The observations of Baly and Tuck (Trans., 1908, 93,1902) with regard to the presence of bands corresponding with 1/h 3125 and 1/A 3220 in naphthalene and its derivative are confirmed. Hartley represented the naphthalene curve for dilute solutions as being characterised by four narrow bands. Bclly and Tuck consider that their broad band l/h 3700 corresponds with Hartley’s four bands. The curves obtained by the present authord for N/lOOO-solutions of naphthalene and of its tetramethyl derivative show four narrow bands, and these observations support Hartley’s firsL interpretation.8. “The influence of various substituents on the optical activity of tartramide. Part 111. Halogen-substituted anilides.” By Percy Paraday Frankland and Douglas Frank Twiss. In continuation of the work of one of the authors on the connexion between chemical constitution and optical activity, and more especially on the effect on rotatory power exercised by substituting hydrogen in the amido-groups of tartramide (see T~ans.,1903, 83,1342, 1349; 1906, 89, 1852), the preparation and properties of the three chloro- and three bromo-anilides of tartaric acid were described. The m-iodo- anilide, which mill be more fully described later, has also been compared as regards its rotation with the other halogen-anilides. The relation between the optical activity of these compounds and that of tartranilide and of the tartarotoluidides was discussed.6 9. The action of water of crystallisation on calcium carbide.” By Irvine Ildasson. It was shown that on mixing excess of powdered calcium carbide with powdered crystalline hydrates, generation of acetylene takes place with great velocity, in some cases at laboratory temperature, in others at higher temperatures. The volume of gas can, after standardisa- tion, be used as a meassureof the amount of dehydration. Of twenty-two hydrated salts examined, many are rendered anhydrous, whilst others form stable lower hydrates, some of which have not previously been recorded.When ammonium salts are dehydrated with calcium carbide, it is found that in most cases no ammonia is liberated, even at 160°, and in spite of the presence of calcium hydroxide. Crystalline acids and acid salts do not react as acids on the carbide or hydroxide. 10. ‘(Decomposition of dimercurammonium nitrite by heat.” By Prafulla Chandra Biiy and A. (3. Ghosh. When its temperature is slowly raised to 250°, dimercurammonium nitrite, NHg,NO,, decomposes, with the production of mercury, oxygen, nitrogen, and nitrous oxide. The volume of the nitrogen is about twice Bhat of the nitrous oxide. The oxygen is quite small in quantity, but never wanting. Nitric oxide is entirely absent, except when the salt has been rapidly heated.The principal decomposition, expressed by the equation : NHg,ru’O, =N, + 2Hg0, resembles that of ammonium nitrite into nitrogen and water. The equation NHg,NO, =N,O +Hg + HgO represents another mode of decomposi-tion. 11. ‘(The adsorption of uranium-X by barium sulphate.” By Arthur John Berry. Determinations of the adsorption of uranium-X by barium sulphate have been made by precipitating the barium sulphate in solutions of uranyl nitrate in radioactive equilibrium, measurements being made of the P-rny activity of the precipitate. It has been found that the quantity ‘Og(a;-x)_____is a constant, where a is the initial amount oflog x/m uranium-X, x the amount adsorbed, and m the mass of barium sulphate adsorbing it.The value of the constant depends on various conditions, chiefly on the dilution and on the amount of sulphuric acid. Other things being equal, dilution and excess of sulphuric acid favour adeorpt ion. 7 12. “Experiments on the Walden inversion. Part 111. Optically active P-hydroxy-P-phenylpropionicacids and the corresponding p-bromo-P-phenylpropionic acids.” By Alex. McKenzie and Herbert Brooke Perren Hpmphries. The resolution of inactive P-hydroxy-P-phenylpropionicacid into its optically active components was described. The displacement of the hydroxy-group in these acids by bromine has been studied, and also the displacement of bromine by the hydroxy-group in the corresponding active bromo-acids. 13.‘(The double nitrites of mercury and the metals of the alkaline earths.” By Prafulla Chandra Ray. The author has used the general method of preparation of the double nitrites of mercury and the alkali metals (Trans., 1907, 91, 2031) in order to obtain similar double nitrites of mercury and the alkaline earths. Tbe following salts mere described : mercuric calcium nitrite, Hg(NO,),,Ca(NO,),,SH,O ;mercuric strontium nitrite, 3Hg(N02)2,2Sr( N02),,5H@, itud nzercu7-ic bc~iumnitrite, 3Hg(N0,),,2Ba(N0,),,5H20. 14. “The resin acids of the Coniferae. Part 11. Matai-resinol.” By Thomas Hill Easterfield and James Bee. The heart resin of the ‘&Matai ” tree (Podocarpus spicatus) consists chiefly of a crystalline substance, C,9H2006,isomeric with the pino- resinol obtained by M.Bamberger from the exudation-resin of Pinus Laricio and Picea vulgaris. Both compounds contain two methoxy- and two hydroxy-groups. Xatairesinol is a lactone ; it melts at 119’, and has [.ID -4.89’. The Znctonic acid, disulphonic acid, and ncetyl and benxoyl derivatives were described. 15. Note on the supposed permeability of glass.” By Alfred Vincent Elsden. C. Zengelis (Zeitsch. physikal. Cl’ern., 1909, 65, 341) describes experiments in which the vapoura of various substances appeared to pass through glass .at the ordinary temperature. In one of his experiments, silver foil was placed on the outside of a sealed flask containing iodine, the whole being placed in an air-tight vessel. The silver showed distinct signs of attack in three days.Zengelis con- siders that there was a real loss of weight in Landolt’s experiments, 8 due to the loss of vapours through the glass walls of the containing vessels. On the other hand, Landolt himself has drawn a contrary conclusion. Since, according to Zengelis, iodine vapour can pass through glass with such readiness, it should be possible to detect a progressive loss of weight of a sealed glass vessel containing iodine. In order to test this, some iodine was placed in a small-thin walled glass tube of about 2 mm. diameter, formed by drawing out a test-tube, the tube being then sealed up in the blowpipe flame. It was cleaned and placed in a box containing silver leaf to absorb any iodine vapour which might pass through the glass.This tube was carefully weighed from time to time during nine months, but no loss OC weight could be detected. The weights observed were : Gram : 0.15331 0.15330 0.15329 0.15332 0-15332 0.15332 0-15333 0.15332 0’15331 Date : 20/3/09 22/3/09 28/3/09 19/4/09 1/8/09 2/8/09 29/8/09 4/9/09 20/12/09 In another experiment, a sealed glass tube containing iodine was sealed within a larger glass tube containing silver leaf. At the end of nine months the silvar leaf showed no signs of attack. Since these experiments mere started, A. Stock and H. Heynemnnn (Ber., 1909, 42, 1800) have published the result of a similar experiment, but have not confirmed Zengelis’ observations, which are probably the result of imperfect sealing or the presence of minute cracks and bnbbles in the glass.16. ‘‘3:5-Dichloro-o-phthalic acid.” By Arthur William Crossley and Gertrude Holland Wren. 3 :5-Dichloro-o-phthalic acid has been synthesised from 3 :5-dinitro-o-xylene as a starting point, and its properties have been compared with those of the acid obtained by Crossley and Le Sueur (Trans., 1902, 81, 1533) from the product of the action of phosphorus penta- chloride on dimethyldihydroresorcin, with the result that the two acids have been proved identical (compare Villiger, Ber., 1909, 42, 3529). 17. A new dilution law.” (Preliminary note.) By James Riddick Partington. Ostwald’s dilution formula, a2/(1-a)v = constant, assumes that ionisation is spontaneous in the same sense as the thermal dissociation of a gas.In the ionisation of a gas by Rontgen rays, etc., the rapidly 9 moving ion exetts great influence on the ionisation of molecules in its path. Larmor has made a passing suggestion that a, similar influence may be exerted by ions in solutions of electrolytes. This leads to the equation :a2/(v+Ka)(1 -a)=constant, Ii being a new constant. This is found tolbe in quantitative agreement with the data for potassium, lithium, sodium and ammonium chlorides, lithium, sodium and silver nitrates, and potassium iodide, all of which show marked deviations from Ostwald’s formula. The following examples illustrate this : (1) Potassium chloride in aqueous solution at 18O. H = 0.018 0.015 0.016 0.017 0.016 K1 = 0.0239 0.0235 0.0337 0.0652 0.1025 K = constant calculated by the new formula, K1 is that calculated by Ostwald’s formula.(2) Silver nitrate in aqueous solution at 18’. K = 0.0062 0*0059 0.0061 0.0068 K1 = 0.0089 0.0088 0.0115 0.0216 18. 2-Phenyl-l : 3-benzoxazine-4-one.”c4 By Arthur Walsh Titherley. The unsaturated cyclic compound C,H < (2-pTi,enpl-l:3-. 0-C*Ph 4be9axoxazine-4-one) has been synthesised from phenyl salicy late and phenylbenzamidine. At 110° phenol is eliminated, forming the tautomeric compound snZicyl~l~erz?lZbenzarnidine(I and 11), which by reversible decomposition yields aniline and the cyclic compound (IV) , probably through the intermediate third tautomeric form (111) : (IV. 1 (111.) The same unsaturated cyclic compound (IV) has also been obtained by the catalytic action of hydrogen chloride on 0-and N-benzoy1- salicylamides between llOo and 140 by removing the water as it is produced.The unstable 2-hydroxy- and 2-chloro-dihydrobenzoxazone 10 derivatives (Vand VI) appear to be formed as intermediate compounds which cannot be isolated. (VI.) 2-Pheny l-1 :3-benzoxnzine-4-one melts at 106O, and possesses marked additive properties. It is comparatively stable towards aqueous alkalis, but is rapidly decomposed in presence of hydrogen ions, com-bining with water with formation of the 3-benzoylsalicylamide, through the intermediate compound (V). Aniline is similarly added, yielding the above salicylphenglbenzamidine (I and 11) in yellow needles melting at 106O, but the reaction is reversible, and the amidine deriv- ative readily loses aniline on heating, with production of 2-phenyl- 1:3-benzoxazine-4-one.19. '' The intramolecular rearrangement of diphenylamine ortho- sulphoxides. Part 11." By Edward de Barry Barnett and Samuel Smiles. ,V-Methyldiphenylamine o-sulphoxide is converted into the azo-thionium salt without loss or rearrangement of the methyl group. Hence with the imino-sulphoxides the iseaction does not involve the direct migration of hydrogen from the imino- to the thionyl group. In this reaction the sulphoxide salts are formed as initial products, and it is these substances which are converted into the azothioniurn derivatives. The process which the sulphoxide salts undergo in the final stage of the reaction cannot be conclusively determined, but tlie alternative hypotheses : (a) elimination of water, or (b) migration of hydroxyl, afford a satisfactory explanation of the change. 20.'(The effect of contiguous unsaturated groups on optical activity. Bart IV. Conjugated systems containing more than two un-saturated groups." By Sydney Robert Edminson and Thomas Percy Hilditch. The change of rotatory power on successively increasing the number of adjacent unsaturated groups attached to ail optically active system has been studied in the cases of phenolic derivatives (of the type of 11 o-hydroxpbenzplideneacetone,etc.) and naphthyl(2-aceto- and 2-benzo-a-naphthol) esters of cnmphoric and camphor-P-sulphonic acids.An approximation to the normal rotatory power of esters of these acids has been obtained by examination of their ethyl, m-propyl, and n-butyl derivatives. Both series of hydrogen camphorates show accompanying increase of molecular rotatory power with increasing number of unsaturated groups, but the camphor-/I-sulphonates are less definite. Combining these results with various data which previous work has rendered it possible to collate, it is found that of eleven available series, four show a progressive increase, four a progressive decrease, and the remaining three indefinite relations to the optical activity of the corresponding compound containing two contiguous unsaturated radicles.No generalisation is therefore possible, but it is noticeable that practically all these unsatiirnted compounds possess rotatory powers greater than the normal value of saturated derivatives. 21. ‘.The alkaloids of the Pukatea.” By Bernard Cracroft Aston. The Pukaten (Lrcurelict nova+ Zealaadiae) has been found to contain three alkaloids, namely : pukrcteine, Cl7HI70,N,which is crystalline, melts at 200°, and has [a],-220’ ; Zaureline, C,9H,10,N, which is amorphous, but forms well crgstallised salts ; and Zcm~epukine, C,,H,,O,N, which is also amorphous. The physiological action of pukateine (in the form of its hydro-chloride) resembles that of strychnine, but is not so intense. 22. ‘* The Friedel-Crafts’ reaction applied to naphthalene. Part I.Syntheses with di- and tri-alkyl halides.” By Annie Homer. The Friedel-Crafts’ reacbion with naphthalene proceeds according to two equations : RH +R,Cl= RE, -I-HC1 (1) RH +RH= RR+ 2H (2)-Both reactions occur simultmeously, but if the reaction is initiated at a high temperature, then the relative velocity of (2) is so much greater than that of (1) that there is a complete preponderance of the pro-ducts of reaction (2) over those of reaction (1). The work was confined to the study of the action of ethylidene chloride, methylene chloride, ethylene bromide, and chloroform on naphthalene. It mat3 found that the reaction proceeded primarily according to 12 reaction (1) in the case of ethylidene chloride, ethylene bromide, and chloroform, although the products finally isolated mere those due to secondary reactions taking place.In the case of methylene chloride the only products which could be obtained were those in accordance with reaction (2), as it was not possible to work under conditions favourable to reaction (1). 23. (‘The Friedel-Crafts’ reaction applied to naphthalene. Part 11. The action of acetylene tetrachloride and of acetylene tetra- bromide. Preparation of ~&’/3’-dinaphthanthracene.” By Annie Homer. From among the products of the action of acetylene tetrachloride and acetylene tetrabromide on naphthalene in presence of aluminium chloride there has been isolated a substance melting at 267.5’, and having the formula C&HL4. This hydrocarbon is identical with 8 substance obtained by Dewar and Jones by the action of nickel carbonyl on naphthalene (lkans., 1904, 85, 212), but which had not been investigated by them.The formation of the substance by these two reactions, which in the benzene series yield anthracene derivatives, together with the ease with which the hydrocarbon can be reduced to a hexahydride, point to its being a&’P’-dinaphthitnthracene. The melting point of the compound, its persistent colour, the colour of its sulphuric acid solution, and the melting point of its quinone and picrate a11 show that it is not the same dinaphthanthracene as that prepared by Hartenstein (Diss., Jena, 1892), which, from the mode of forma-tion, must have the /lPPP’-configuration.
