Of the following papers, those marked * were read : +ll5. ‘‘The absorption spectra of the nitrates in relation Cs the ionic theory.” By Edward Charles Cyril Baly, Katharine Alice Burke, and Efie Gwendoline Marsden.The absorption spectra have been examined of nitric acid and lithium, ammonium, and silver nitrates dissolved in alcohol and in water and in various mixtures of these solvents. A comparison between the persistencies of the absorption band shown by AT/lO-solutions of lithium and ammonium nitrates shows that considerable variations occur as the percentage of water in the solvent is increased. For example, when the solvent contains 3 per cent. of water a great decrease in the persistence of the absorption band is obtained as compared with that observed in pure alcohol and in alcohol contain- ing 10 per cent. of water. On the other hand, the electrical conduc- tivities of the iV/lO-solutions do not show any such variations, but only a steady increase with increase of water in the solvent.If, however, the limiting conductivities of the solutions be observed, it is found that a, minimum is obtained when the solvent contains 3 per cent. of water. Nitric acid differs from the metallic nitrates in that it shows no absorption band and possesses very small electrical conductivity in pure alcoholic solution. The absorption band is developed, however, and the conductivity greatly increased with addition of water to the solvent. The limiting conductivity of the nitric acid solutions also shows a minimum with 3 per cent. of water in the solvent. The results afford strong support to the theory of hydrated ions, the decrease in limiting conductivity and the absorption band observed with the solvent containing 3 per cent.of water being doubtless due to the hydration taking place. 145 DISCUSSION. Dr. SENTERasked if there was any evidence of a connexion between the viscosity of the (mixed} solvent and the limiting molecular con- ductivity of the salts (compare Walden, Zeitsch. physikal. Chem., 1906, 55,217). Mr. BALYsaid that the viscosity of the solvent seemed to exert only a very small influence. A mixture of alcohol and water in equal proportions showed a maximum viscosity, and although there was a minimum in the limiting conductivity of lithium nitrate near this point, neither silver nitrate nor ammonium nitrate showed any such minimum. W6. “Studies in the camphane series. Part XXVI. Aryl derivatives of iminocamphor.” By Martin Onslow Forster and Tom Thornley.By condensing camphorquinone with aniline and some of its dariv- atives, aryliminocamphors have been obtained and are found to possess unusually high specific and molecular rotatory power. Reduction of these compounds leads to the corresponding derivatives of amino-camphor, and is accompanied by profound depression of optical activity. DISCUSSION. Mr. P. W. ROBERTSONasked whether the coloured compound in-vestigated dissolved with different intensities in different solvents, and if so, whether any relationship had been observed between the intensity of colour and the magnitude of the specific rotation. *117. (‘Substituted dihydrobenzenes. Part 111. The so-called 1 : 1-dimethyl-42: 5-cycZohexadiene of Harries and Antoni.” By Arthur William Crossley and Nora Renouf.It was shown that the hydrocarbon described by Harries and Antoni (AnnuZen, 190S, 328,88) as 1 :l-dimethyl-42:5-cycZohexadiene is in reality a mixture of the cyclohexadienes with the two methyl groups in the 1 :2-and 1 : 3-positions, and probably does not contain any 1:1-8imethylcycZohexadiene. *118. Diethoxythioxan ; a relation between the refractive power 6c and chemical activity of some sulphur compounds.” By Hans Thacher Clarke and Samuel Smiles. The interaction of sodium sulphide and chloroacetal in alcoholic solution furnishes acetal sulphide, which, on treatment with mineral 146 acid, yields the cyclic sulphide, diethoxythioxan. The reactivity of the sulphur in the latter compound has been qualitatively studied, and it is found to be abnormally low in comparison with that of the same element in acetal sulphide, benzyl sulphide, or saturated aliphatic sulphides.The authors consider that this depressed activity cannot be satisfactorily explained by steric hindrance, and, instead, ofEer the L hypothesis that the residual affinities of the unsaturated cyclic sulphur and oxygen partly saturitte one another. A similar explanation may be applied to other compounds containing bivalent sulphur of abnormally low activity, for example, thiophen and phenyl sulphide. The refractivity of these sulphur compounds also has been studied, and it was shown that a subnormal reactivity is accompanied by abnormal refractive power.The thioxan derivative appears to possess a slight optical anomaly. DIscussroN. Dr. SMILES,in reply to Mr. Baly, stated that attempts made with the object of preparing a hydrochloride of diethoxythioxan had been un- successful. No indications of the substance having the structure of a hydroxytetrahydrothiophen, as suggested by Dr. Porster, had been found, since acyl derivatives were unobtainable. In reply to the President’s question as to the action of oxidising agents, hydrogen dioxide was without action, but hot concentrated nitric acid destroyed the substance, sulphuric acid being formed. 119. ‘‘ The affinity constants of hydroxy-and alkyloxy-acids.” By Alexander Findlay, William Ernest Stephen Turner, and Gertrude Emily Owen.The affinity constants of phenylmethoxy-, phenylethoxy-, and phenyl- propoxy-acetic acids and of a-and /3-hydroxy-/3-phenylpropionicacids have been determined at 25’. The values of the constant 100k were found equal to 0.074, 0.053, 0.048, 0.019, and 0*0040respectively. 120. ‘( The chlorination of acetanilide.” By William Jacob Jones and Kennedy Joseph Previt6 Orton. When chlorinated by bleaching powder solution in acetic acid solution, acetanilide is converted into a mixture of 0-and p-chloro- acetanilides, of which the ortho-compound forms about 45 per cent., and not, as believed heretofore, less than 10 per cent. If the concen- tration of the acetic acid is less than 2 per cent., acetylchloroamino- benzene is formed together mith the two chloroacetanilides ; when the 147 acetic acid is diluted to 0.25 per cent., the chloroamine forms the chief product.The transformation of the acetylchloroaminobenzene yields a mixture of the isomeric chloroacetanilides in the same proportion. Chlorination of acetanilide by chlorine in glacial acetic acid solution gives a mixture of the two anilides, in which 30 to 32 per cent. of the ortho-derivative is present. 121. ‘‘Esterification constants of substituted acrylic acids. Part IV.” By John Joseph Sudborough and Morton James Pryce Davies. The constants, EZiOH,have been determined for the following acids : Acrylic, crotonic, a-methylacrylic, PP-dimethylacrylic, angelic, tiglic, trimethylacrylic, isobutyric, a-methylbutyric, isovaleric, up-di-methylbutyric.The results indicate the retarding effect of the methyl groups and also establish the retarding effect of the double linking in the ap-position. The most remarkable point is that /3P-dimethylacrylic acid ie esterified less readily than a-methylacrylic acid or tiglic acid. 122. “The action of the halogens on aromatic hydrazines.” By Frederick Daniel Ghattaway. From the behaviour of the primary aromatic hydrazines when oxidised, it seemed likely that evidence of the formation of the mono- N-halogen substituted derivatives, which should be the first products of the interaction of primary aromatic hydrazines and any halogen, would be obtained if the reactions were carried out in presence of alkalis.Such compounds in presence of alkalis would be unstable, and might be expected to decompose into nitrogen, halogen hydride, and hydrocarbons. N-Dihalogen substituted derivatives, corresponding with the halogen acid additive products of diazonium salts, might be formed in small amount under favourable conditions and similarly decompose, yielding a monohalogen-substituted hydrocarbon. These expectations hare been completely realised. When chlorine or bromine is brought into contact with a primary aromatic hydrazine in presence of potassium or sodium hydroxide, very vigorous action takes place, nitrogen is freely evolved, and the *NH*NH,group is replaced by hydrogen; for example, by the action of bromine on phenylhydrazine, p-bromophenylh ydrazine, o-tolylhydrazine, and p-tolylhydrazine, there are produced benzene, p-bromobenzene, and toluene respectively.Any theory which attempts to explain the action of the halogens on primary aromatic bydrazines must therefore account for the produc- 148 tion of hydrocarbons, mono-, di-, tri-, and tetra-substituted hydro-carbons, azo-derivatives, azoimides, hydrocarbons of the diphenyl series, diazonium salts substituted and unsubstituted in the aromatic nucleus, and the so-called diazonium perbromides. It was explained how the complicated changes, which result in the formation of so many substances of such very different constitutions, all depend on a progressive substitution of hydrogen attached to the nitrogen, thus : Re?R-lf*H *H R*T*X R-7.X H*N*IC--+-H*N*X--3 X-N*H--3 X*N*X’ followed by a breaking down or intramolecular rearrangement of the N-halogen-substituted hydrazines thereby produced.123. “The retarding effect of oxygen on the rate of interaction of chlorine and hydrogen.” By David Leonard Chapman and Patrick Sarsfleld MacBIahon. The authors have shown that when a moist mixture of chlorine and hydrogen containiag a known amount of oxygen is exposed to light of constant intensity, the rate of formation of hydrogen chloride is, to a first approximation, inversely proportional to the amount of oxygen present. It is concluded from this result that the sensitiveness of a mixture of chlorine and hydrogen from which all oxygen had been removed would be infinite.The above quantitative relation was shown to be in harmony with the theory of inhibition advanced by Burgess and Chapman (Trans., 1906, 89, 1433). 124. “The colour of aqueous solutions of violuric acid.” By Frederick George Donnan and Wilhelm Schneider. Experiments were described which show that the conclusion of W. N. Hartley (Trans.,1905, 87, 1797), that pure aqueous solutions of violuric acid are colourless, is erroneous. 125. An examination of irritant woods. Part I. Chloroxglonine from East Indian satinwood.” By Samuel James Manson Auld. From East Indian satinwood, derived from Cldoroxylon swietcnicc, which has been reported to possess irritant proper ties, have been separated calcium oxalate, a peculiar protein compound, two inert resins, a fixed oil, and an alkaloid, C,,H,,07N.As the alkaloid cannot be identified with any known base, it is proposed to call it chloroxyloninc. 149 ChloroxyIonine is a weak monoacidic base, and several of its salts have been prepared and characterised. It melts at 183--1S3O, contains four methoxyl groups, and is I,?evorotatory ([u]: -9’18’). The physiological action of chloroxylonine is being investigated by Prof. Cash, of Aberdeen, and in certain circumstances it‘:seems capable of causing dermatitis similar to that ascribed to the wood itself. 126. (( Diazohydroxglamino-compoundsand the influence of snbstitu-ting groups on the stability of their molecules. Part 11.” By Norman Leslie Gebhard and Herbert Bryan Thompson.The various diazohydroxylamino-compounds,prepared as described in the previous paper (TT~Ls.,1909, 95, 7673, have been examined with a, view to determine the influence, due to position in the molecule, which the various substituting groups have on the stability of the compound considered. The action of bromine dissolved in an organic solvent, besides being a decomposing one, is of a sub-stituting nature, and consequently of little use in determining the object in view ; several new diazohydroxylamino-compounds mere, however, prepared by its means. The action of hydrochloric acid in an organic solvent under comparable conditions for the various series of isomeric substitution products was also investigated ;it was found that the nitro-, brorno-, and carbethoxy-groups (but not the methyl group), when present in the ortho-position, greatly increased the stability, but as soon as the siibstituting group entered the meta- or para-positions the stability of the molecule decreased enormously. 127.A new method of preparing camphoric anhydride.” By John Percy Edgerton. When camphoric acid is treated with chlorosulphonic acid a vigoroils reaction takes place according to the equation : C,Hl,(C0,H)2 +HSO,Cl= C,H14<gE>0 +H,SO, +HCI, the principal product being camphoric anhydride, which can be quickly prepared as follows : One hundred grams of finely powdered camphoric acid are placed in a capacious flask fitted with a drying tube containing calcium chloride, and 33 C.C.of chlorosulphonic acid are added; the mixture is then warmed on the water-bath, n further quantity of 16.5 C.C. of chlorosulphonic acid is added, and the whole again warmed for about half an hour until the evolution of gas bas practically ceased. The mass is then mixed with water, filtered 150 through glass wool, and washed until free from acid. The camphoric anhydride crystallises from methylated spirit in fine needles, which, if not quite pure, can be obtained pure by a second crystallieation. 128. (‘The action of phosphorus pentachloride on benzamide.” By Arthur Walsh Titherley and Elizabeth Worrall. In the action of phosphorus pentachloride on benzamide different results are obtained according to whether the action takes place (1) in the cold without a solvent, or (2) in the cold with a solvent, or at 50° wilfh or without a aolvent. In (1)the result appears to be a mixture of phosphoryl chloride and a-chlorobenzimide, C,H,*CCl:NH, which gradually passes into benzonitrile and could not be isolated ;in (2) aa-dichlorobenzylphosphamicchloride, C,H,* CCl,*NH*POCI,, is formed, which immediately loses hydrogen chloride, yielding a-chlorobenxylidene-phosphamic chloride, C,H,*CCl:N*POCI,, as an oil which solidified at low temperatures.The latter compound is comparatively stable at 50’, but decomposes at higher temperatures into benzonitrile and phosphoryl chloride ; on exposure to atmospheric moisture, it yields fine transparent crystals of bepaaoylphosphccmic chloride, C,H,-C(OH) :x’*POCI,ZZ C6H,-CO*NE*POCf (m.p. 115O), which is practicnlly unaffected by cold water. By treatment with aniline, a-chlorobenzylidenephosphamic chloride yields phenyZiminopiio~phoryZphenyl6elzxamidipze, C,H,*C( NHPh):N*PO:N Ph (m. p. 227-228’). Benzoylphosphamic chloride on treatment with aniline yields phenyl-imi~op~os~~horylbenzamide, C,H,*CO*NH*PO:KPh tC,H,*C(OH):N.PO:NPh (m. p. 226O), which is soluble in sodium hydroxide, or benxoylamino-aniZinophosphoryE chloride, C,H,*CO*NH*POCl*NHPh(m. p. 176O), according to the conditions of the reaction. The latter compound passes into the former by treatment with aniline, and does not yield the expected dianilino-derivative. Benzoylphosphamic chloride readily undergoes replacement of the two chlorine atoms by hydroxyl on treatment with water in acetone aolution, yielding benxoylphosphamic acid, C6H,*CO NH*PO(OH), (m.p. 157-1558’), vhich is readily soluble in water, and forms salts. The acid is rapidly decomposed by water at looo, yielding phosphoric acid and benzamide, which crystallisea out on cooling. 129. “Estimation of iron by permanganate in the presence of hydrogen chloride.” By John Albert Newton Friend. The author draws attention to the fact that the rate at which the permanganate is added to the ferrous solution greatly affects the 151 value of the titration. It is suggested that the reaction takes place in two stages. First, a partial reduction resulting in the oxidation of some of the iron, and the formation of an unstable perchloride of manganese. The latter substance then oxidises the ferrous iron according to the equation : MnCl@+,,+xFeC1, MnCl, +xFeC13 until equilibrium is established. If the directions given are rigidly adhered to, fairly accurate estimations of iron may be obtained in the presence of Nlkhydro-chloric acid.130. “Contributions to the chemistry of the terpenes. Part V. The action of ohromyl chloride on terpinene and on limonene.” By George Gerald Henderson and William Cameron. When chromyl chloride (2 mols.), largely diluted with carbon disulphide, is added to a similar solution of terpinene (1 mol.), a brown solid is formed which is decomposed by water, yielding a solution of chromic chloride and a brown, oily liquid.The liquid oxidation product contains small quantities of cymene and of a ketone of the formula C,H,,O, but is mainly composed of a-p-tolylpropaldehyde, C,H,Me-CHMe*CHO, and p-tolyl methyl ketone, COMe*C,H,Me, both of which are derivatives of cymene. Hence the behaviour of terpinene towards chromyl chloride is different from that of pinene and of camphene, for whilst each of the latter hydrocarbons yields an additive product, C,,H,,,2Cr02CI,, terpinene, on the other hand, is for the most part first oxidised to cymene, which then forms the compound CloH1,,2CrO,Cl2, from which the aldehyde and the ketone are produced by the action of water. It has also been found that the aldehyde and the ketone formei,ly prepared from limonene in a similar manner (Trans., 1907, 91,1871) are largely composed of a-p- tolylpropaldehyde and p-tolyl methyl ketone respectively, and therefore that limonene must likewise undergo at least partial oxidation to cymene when attacked by chromyl chloride under the conditions described. 131.The influence of solvents on the rotation of optically active compounds. Part XV. Mixed solvents.” By Thomas Stewart Patterson and Harvey Hugh Montgomerie. The influence of two pairs of solvents on the rotation of an active compound was described, and the results were discussed in connexion with the heat of mixture of the various compounds concerned, and also with reference to the discrimination of compounds in solulions, 152 132.Optioally active reduced naphthoic acids. Part IV. Com-parison of the rotatory powers of the di-and tetra-hydronaphthoic acids with those of phenylallylacetic, a-phenylvaleric, P-phenyl- a-ethyl-and P-phenyl-a-methyl-propionicacids." By Robert Howson Pickard and Joseph Yates. A description was given of the resolution of five racemic acids by the fractional crystallisation of their E-menthylamine salts. Ths principal experimental results are recorded in the following table : Jlenthylarnine salt. Acid. --' [l!ID of Dextro-[MJ, [If],in [KJD [l11Din sodium salt in ethylrotatory acids. M. p. at 20".

Part 11." By Alexander Findlay and Evelyn Marion Hickmans. The velocities of saponification of e thy1 glycollate, lactate, a-hydroxy- p-phenylpropionate, y-hydroxy-y-phenylbutyrate,phenylpropionate, propionate, P-hydroxy-P-phenylpropionate,and of methyl phenylacetate have been determined. The values of the saponification constant obtained for these esters were 75, 63.5, 40.1, 16.5, 6.9, 5.3, 4.9,27.4 respectively. From these numbers it is found that the introduction of a phenyl group accelerates the velocity of saponification, except when the ester contains the hydroxyl group.In this case, introduction of a phenyl group lowers the velocity of saponification (for example, ethyl rnandelate and ethyl glycollate). Introduction of an hydroxyl group increases the saponification constant to nearly twelve times its value in the case of esters not containing the phenyl group, but to only five to six times its value in the case of phenylated esters. A comparison of the saponification constants of the ethyl esters with the affinity constants of the corresponding acids shows that there is no general relationship between the two magnitude9 . 134. ‘I Apparatus for experiments at high temperatures and pres-sures, and its application to the study of carbon.(A correc-tion).” By Richard Threlfall. The author recently described an experiment (Trans., 190.3, 93, 1333) in which graphite was forced through a narrow tube by a comparatively small pressure-negligible in comparison with the pressures under which the property of the fluidity of graphite was employed to transmit pressure. The experiment there described can be repeated as often as desired, but the inference that pressure can be transmitted in all circumstances without any appreciable loss of head by crystalline graphite is wrong. Further experience has shown that when graphibe flows it does not obey the laws regulating the flow sf liquids, but that the fluidity of graphite is a function of the absolute pressure to which it is exposed.Under high pressures the graphite consolidates, and in this state transmits pressure very badly. For instance, in the experiment described (Zoc. cit.), it is now known that rapid flow took place under a pressure of a few hundred pounds per square inch-the graphite flowing freely into the air. When, however, the graphite, otherwise under similar conditions, was employed to force a pointed piston of hard steel against a soft steel plate, and pressures of 50 to 100 tons per square inch were employed for the purpose, a loss of head of many tons per square inch was found. The observation was made by measuring the depth to which the pointed piston entered the steel plate, and then causing it to penetrate to the same depth by direct pressure.In most of the experiments described in the paper referred to, the graphite flowed into a bath of molten magnesia through a very short neck of unmelted tube, and ccnsequently the experimental results quoted are probably little or not at all affected by the error involved in supposing that graphite, when it flows, obeys the ordinary laws OF flow of liquids. Some preliminary experiments indicate that cdd lead flowing under high pressure is much more truly a fluid than crystalline graphite. 135. Experiments on the constitution of the aloins. Part I.” By Robert Robinson and John Lionel Simonsen. The authors communicated the results of some further experiments on the nature of rhein, a preliminary note of which has already appeared (Proc., 1909, 26, 76).136. “The constitution of the salts of barbituric acid.” By John Kerfoot WoodLand Emma Alexander Anderson. The authors have shown that by the action of acetic anhydride on ai mixture of carbamide and malonic acld, ureidomalonamide is formed, together with barbituric acid and an apparently complex substance, the constitution of which has not been established. Ureidomalon-amide is a white, very sparingly soluble substance, which, on treatment with sodium hydroxide, is converteci into sodium barbiturate. This action shows that the constitution of the salts of barbituric acid is represented by the general formula MO-C<NH.cO>NH, where Ic3: isCH CO a univalent metal.Theoretical considerations leading to a similar conclusion were also discussed. 137. “The estimation of carbonates in presence of nitrites, swlphides. or sulphites by means of potassium dichromate.” By Ernest Robert Marle. It was proved that soluble carbonates and carbonates of bases which form soluble chrornates are quantitatively decomposed by aqueous potassium dichromate. The action of potassium dichromate on nitrites has been investigated. On distillation with dichromate, a nitrite yields nitrous acid, although the mixed solution apparently contains no free nitrous acid, The yield of nitrous acid increases with the concentration of the nitrite, but is almost independent of that of the dichromate. Prolonged distillation, either adding water at the rate at which the liquid distils, or making the solution up to its original volume after, gay, 100 C.C.has distilled over, gives 60-70 per cent. of the nitrite as nitrous acid. The residual nitrite in the flask is estimated, and the loss of 10-15 per cent. is accounted for by the decomposition of nitrous acid into nitric acid and nitric oxide, some of the nitric oxids remaining dissolved in the dichromate solution. An apparatus was described with which carbonates can be estimated in the presence of nitrites, the mixture being distilled with dichromate under reflux. The carbon dioxide is thus freed from nitrous acid, and the nitric oxide formed is negligible. The method is found to give- accurate result s.155 ADDITIONS TO THE LIBRARY. I. Donations.
