Of the following Papers, those marked * were read. “10, 6‘ Observations upon the oxidation of nitrogen gas.” By Lord Rayleigh, .F.R.S. On the basis of Davy’s assertion that the clissolved nitrogen of water is oxidised during electrolysis, various attempts were made ; but they led to no useful result, even leaving it doubtful whether Davy’s facts are correct.The influence of pressure upon the oxidation of nitrogen by the electric flame was next examined. It appeared that, while in a small vessel the effect of increasecl pressure was favourable, but little advan- tage resulted when the vessel was large enough to give the maximuin 18 effect at a given pressure. The pressures compared were two atinos- pheres, one atmosphere, and half an atmosphere. The remainder of the paper is devoted to a detailed description of a large scale apparatus (shown working) in which 31 litres of mixed gases enter into combination per hour, at an expenditure of about 1 horse-power. DXSCUSSION. PROFESSOR referring to Lord Rayleigh’s remark as toARMSTRONG, the importance of the platinum electrodes being red-hot, enquired whether there was any evidence that the platinum played a special part in the process. PROFESSOR suggested, as an explanation of the better results RAMSAY obtained when a large vessel was employed, that nitric oxide was the first product, and that this subsequently combined with oxygen to form the peroxide.THE PRESIDENT considered it probable that some of the oxide of nitrogen first formed was subsequently decomposed by the heat of the flame itself, and that the large vessel, by presenting a large surface of alkaline liquid, favoured the rapid absorption of the oxide of nitrogen, and thus less was decomposed than would be the case in a smaller vessel, where the rate of absorption was smaller.He enquired with what proportion of nitrogen to oxygen combustion occurred most rapidly. PROFESSORM‘LEODremarked that he had made an experiment fn the manner originally suggested by Cavendish, and had found that nitrite as well as nitrate was formed. LORDRAYLEIGH,in reply, said that the larger vessel apparently led to better results by increasing the facilities for absorption. He did not consider that the platinum played any special part in the process. The action seemed most rapid when the proportion of air to oxygen was as about 5 to 6, which corresponds with two of nitrogen to three of oxygen. He believed that both nitrite and nitrate were formed. The apparatus shown was suitable for $he preliminary concentration, but not for the final purification of argon.*11. 6b On some apparatus for steam-distillation.” By F. E. Matthews, Ph.D. In this paper several forms of apparatus for automatically steam- distilling substances are described. Some solids of high melting point may be separated by boiling the substance mixed with water in a flask fitted with a reflux condenser, the solid substance adheres to the inside of the condenser, whence it can be removed from time to time. For liquids heavier than water, the flask in which the mixture is boiled is connected with the side tube of an ordinary distilling-flask ; this distilling-flask, filled with water up to the side-tube, serves as the receiver. Into the neck of the receiver and passing below the surface of the water, a bent Liebig’s condenser is fitted which has the peculiarity of having a hole made in it a short distance above the level of the water in the receiver.On boiling the mixture in the flask, the vapours pass up the side-tube of the receiver into the upper portion of its neck and thence through the hole into the receiver when condensation takes place. The condensed liquids run down the condenser to the water- level in the receiver, where a drop of the heavy fluid sufficiently large to sink is formed froni time to time. The condensed liquids displace their own volume of water, which flows from the receiver through the side tube back again to the boiling-flask. In all cases in which vapour is passing in one direction in a tube, and water in the other, the advantage of perforating the tube near its lower end is pointed out.For liquids lighter than water, the apparatus consists of the boiling- flask, which is an ordinary distilling flask; this is connected by the upper opening to an upright tube furnished with a T-piece. The top of the upright tube is connected to the condenser, the lower end dips two or three inches into a Woulfe’s bottle, containing water in sufficient quantity, which serves as the receiver. Through another neck of the Woulfe’s bottle, a second tube passes from the bottom of the bottle and is connected to the side-tube of the boiling-flask. The mixed vapours pass from the boiling-flask into the upright T-tube, thence into the condenser ; there becoming condensed, they fall down into the T-tube, producing a column of liquid which forces water from the bottom of the receiver back into the boiling-flask through its side-tube. A modification of this apparatus dispenses with the necessity of having an india-rubber connection exposed to the hot vapour.In this modification the boiling Aask is an ordinary plain flask. This is con- nected to the condenser by a side-tube blown on to the upright tube. The water returns to the boiling-flask through another T-tube, blown on to the side-tube of the upright tube. For conveniently emptying the receiver without dismantling the apparatus, a separating-funnel with two necks may replace the Woulfe’s bottle of the previous apparatus.Many liquids bump badly when boiled with water ; this can generally be got over by introducing a zinc platinum couple into the boiling-flask. The temperature of the water in the boiling-flask may be raised by dissolving suitable substances such as sulphnric acid or calcic chloride in it, or liquids of higher boiling point may be used. *12. “Researches in the Stilbene Series. I.” By John J. Sudborough, Ph,D. The author has obtained benzil as one of the products of the action of zinc dust and acetic acid on benzo’in ; if the action is con- 20 tinued the benzil disappears and the chief product is deoxybenzoin. The foriiiation of an oxiclation product of benzoi'n by the action on it of zinc dust and acetic acid appeared so remarkable that the author has studied the action of acetic acid alone on benzoin, and he finds that small quantities of benzil are formed if benzoi'n is heated with six times its weight of glacialacetic acid on the water bath for eight-nine hours.By the action of phosphorus peiitacliloride on deoxybenzoln a solid chlorstilbene has been obtained, which differs from Zinin's oily com- pound. It melts at 45O, yields a dibromide and a dichloricle, also with nitrous fumes two compounds probably represented by the formulze Ph-CHNO,*C'ClNO,*Ph (m. p. 128') and Ph*C(NO,):C(NO,)*Ph (yellow prisms in. p. 104-105'). An oily compound can be obtained by the action of phosphorus pentachloride on deoxybenzoyn at low temperatures, The oil contains the same amount of chlorine as solid chlorstilbene.Methylcleoxybenzoi'n and ethylcleoxybenzoi'n on treatment with phos- phorus pentachloride can be niacle to yield b&h oily ancl crystalline compounds, analysis of which points to their being methyl- and ethyl- chlorstilbenes. Solid methylchlorstilbene melts at 124O, and the corre- sponding ethyl compound at 60'. The clichlorides ancl dibromides are also described. The question as to the nature of the oily compounds has not been settled; the author describes a method by which he pro- poses to determine whether they are merely slightly impure forms of the solid compound, true stereo-isomerides, or structurally isomeric with the solid compounds. *13.(;Diortho-substituted benzoic acids. 111. Hydrolysis of sub-stituted benzamides." By John J.Sudborough, Ph. D., Percy G.Jackson,and Lorenzo L. Lloyd. In order to determine whether diortho-substituted benzamides exhibit the same remarkable degree of stability towards hydrolysing agents as characterises the diortho-benzoyl chlorides (Trans., 1895, 67,587) and ethereal salts, the authors hare investigated the following compounds. Ortho-, meta-, and para-brombenzamide ; 2 :4-,2 :6- and 3 :5-dibrom-benzamide ; 2 :4:6- and 3 :4 :5-tribrombenzamide ; 2 :4 :6-trichlor-benzamide ;2 :4 :6-trimethylbenzamide (mesitylformamide) ancl mesityl- acetamide, C6H,Me,.CH,*CONH,. Of the three mono-substituted hrombenzamides the ortho-compound proves to be somewhat more stable in the presence of boiling (30 per cent.) sulphuric acid than the meta- and para-compounds.This agrees with the properties of the correspond- ing methylic monobrombenzoates and of the monobrombenzoyl chlorides. Of the three dibromamides the 2 : 6- or di-ortho-substituted com- pound proves to be the one most difficult to hydrolyse by means of 21 75 per cent, sulphuric acid, and again of the two tribroiiiamides the 2 :4 :6-or symmetrically substituted amicle is much more stable than the isomeric 3 : 4 : 5-tribrombenzamide. 2 : 4 :6-trichlorbenzamide although not hydrolysed so readily as 2 :4-and 3 :5-dibrom- and 3 :4 :5-tribrombeiizamide is less stable than the corresponding 2 : 4 :6-tribrom-compound. The methyl derivatives could not be investigated as regards their hydrolysis with 75 per cent.sulphuric acid, as they are charred and decomposed by this means. Towards 30 per cent. sulphuric acid, the mesitylformamide is much more stable than the corresponding acetamide. In the course of this investigation the following new compounds have been obtained :-3 :5-Dibrombenzainicle, m. p. 187"; 2 : 4 : 6-tri-brombenzonitrile, rn. p. 127"; 2 : 4 : 6-t~ribrombenzamide in. p. 193--194" ; 3 :4 :5-tribrombenzamide, m. p. 199" ; 2 : 4 : 6-trichlor-benzonitrile, m. p. 75" ; 2 :4 : 6-trichlorbenzamicle, in. p. 177"; mesityl-formamide, in. p. 105"; mesitylacetamide, m.p. 210". *14. '(Conversion of camphoroxime into methylcamphorimine and camphenylnitramine." By M. 0. Forster, Ph.D. Further investigation of the base obtained on heating camphoroxime in sealed tubes with methylic iodide has proved it to be the methyl- derivative of Tiemann's camphorimine ;it therefore has the formula C,H,,<QH2 and not, as appeared probable from the preliminary 9 C:N*Me examination (Proc., 1895,11,145),the formula, Cl2HI9N.This is show11 by its behaviour towards concentrated hydrochloric acid at 200°, giving rise to camphor and methylamine. Bfetl~ylcan~l~o~*i~~ne and metlliodicle melt at 270" aiidIqdrocJ~lo~~ide 231-232O, respectively ; the pedwonzide has also been prepared. The action of dilute nitric acid on camphoroxime, if interrupted after a few minutes, gives rise to canzp~nylnitmi~a~ne,which is also formed when a solution of the oxinie in chloroform is treated with nitrogen peroxide.An acid solution of potassium permanganate converts camphor-oxime into an unstable nitroso-derivative, which separates froin the liquid as a sticky, green mass ; when preserved in the desiccator the substance deliquesces, and loses its green colour, the yellow residue yielding camphor when distilled in an atmosphere of steam. 15. ''Note on Wechsler's method for the separation of fatty acids." By Arthur W. Crossley. Wechsler (,Voncctsh., 1893, 14, 462) has described a method for t,lie separation of fatty acids, the principle of which method is contained in the following statement. If to a mixture of two fatty acids four-fifths of the caustic soda necessary to neutralise them be added, and the whole steam-distilled, the distillate contains the pure higher-boiling acid.From the residue of the distillation a further three-fifths of the acids are set free by addition of sulphuric acid, and the whole distilled in steam. Finally, the remaining fifth of the acids is set free, and in this case the distillate contains the lower boiling acid in a pure condition. The purity of the acids contained in the various distillates was proved by converting them into silver salts and subsequent analysis of these salts. After trying this method of separation, with very unsatisfactory results, on a mixture of fatty acids obtained in a research on which Professor Perkin and the author have been engaged for some time past, it was thought advisable to test some of Wechsler’s experimental data. Accordingly, Wechsler’s experiments have been carefully repeated and results obtained which do not agree with that author’s.As Wechsler always worked with equimolecular proportions of fatty acids, the result of some experiments are recorded in which varying proportions of fatty acids were employed. In every case, the results were unsatisfactory, for even when using three molecules of the lower to one of the higher boiling acid, the former was not obtained pure in the last distillate, and the first distillate contained a decided mixture of the two acids. It is therefore to be concluded that Wechsler’s method does not give such good results as its author suggests, nor can it in any way belooked upon as a satisfactory method for separating mixtures of fatty acids.16. “On the crystalline structure of gold and platinum nuggets and gold ingots.” By A. Liversidge, LLD., F.R.S. In view of the theory that gold nuggets are built up of concentric layers deposited round a central nucleus, the author has examined a large number of specimens from various sources. The nuggets were ground down, or sliced through, to obtain sections, which were polished nnd etched by suitable solvents. They all possess a well-marked crystalline structure, and usually enclose foreign substances. The crystalline structure is not incompatible with an aqueous origin ;and the author suggests that the gold has been slowly deposited from soh-tion, either at ordinary or at high temperatures : the nuggets being more or less rolled masses of gold which have been set free from disintegrated veins.17. “On the presence of gold in natural saline deposits and marine plants.” By A. Liversidge, LL.D., F.R.S. The author gives a preliminary account of the results of the examination for gold of rock salt, sylvine, and other similar saline 23 deposits, bittern, sea-weed, kelp, oyster shells, &c. The process of deter-mination used was to add from 0.5 to 5 grams of ferrous sulphate to the unfiltered solution of 100 to 1000 grams of the salt in water. The resulting precipitate was then scorified with lead and cupelled. The natural salts contained from 1 to 2 grains of gold per ton, whilst kelp and bittern furnished in some cases as much as from 14 to 20 grainsI ADDITIONS TO TRE LIBRARY.I. By Puvchase. Berthelot, M.
