DEWARPROFESSOR exhibited a vacuum-jacketted globe containing about half a litre of liquid air, which had been kept for the previous 30 hours at the Royal Institution. Of the following papers, those marked * were read."74. The relative behaviour of chemically prepared and of atmosphericnitrogen in the liquid state." By James Dewar, F.R.S. When gases such as nitrogen, oxygen, or air are liquefied in large quantities, the impurities found in the gases and taken up during the passage through the pumps gradually accumulate, and when the fluids are discharged into vacuum vessels at atmospheric pressure these separate in the solid state. If the solid matter is filtered off from liquid air and the fluid allowed to evaporate slowly from a vacuum ressel, then the last drops of liquid are almost pure oxygen; nitrogen gas containing 3 or 4 per cent. of oxygen when liquefied behaves exactly in the same way.It would appear, there- fore, that no impurity of higher boiling point than oxygen can be separated by ordinary fractional distillat'ion of the liquid air, and if any other material is present it must evaporate along with the nitrogen. By the use of a special arrangement small quantities of gases, in a pure and dry state, amounting to from 100 C.C. to a few litres, may be examined in the liquid condition and the experiment repeated as often as desired with the same specimen of gas. The simple apparatus exhibited, by means of which the condensing point of a gas and afterwards the volatilising rate of the resulting liquid may be observed, may be succinctly described as follows :-A tube of small bore, somewhat drawn out at one extremity, is passed nearly to the bottom of a distillation flask and sealed into the neck.The outer portion of this tube is closed and bent twice at right angles, so that a closed limb is thus formed outside the vessel. The side tube of the flask is sealed after the pure, dry gas under examination has been introduced, together with phosphorus pentoxido, at a known pressure and tempera-ture. The closed limb of the small-bore tube is then cautiously introduced into a vacuum- jacketted tube containing liquid air or oxygen, so arranged that the vapour pressure on the liquid may be 223 gradually lowered by means of an air-pump, and the gas within the tube slowly reduced to the temperature of liquefaction. In this way it is easy to observe the point at which liquid begins to form from different samples of gas placed side by side, and afterwards, when the temperature of the liquid air bath is allowed to rise, the point at which the last drops of the liquids resume the gaseous form.Nitrogen obtained from atmospheric air has been compared in this manner with nitrogen prepared from nitric oxide without any differ- ences between them being detected. Atmospheric nitrogen wbich has been passed over heated magnesium showed, however, a marked difference as compared with gas which had not been SO treated. Although its condensing point was not far removed from that of the untreated material, as a matter of fact this point, as well as the volatilising point of the resulting liquid, was higher than before, that is to say, nitrogen which has been passed over heated magnesium becomes liquid a little before the original specimen, and the liquid evaporates rather more slowly and lasts longer when both substances are compared under precisely similar circumstances.Nitrogen chemically yrepared from nitric oxide was likewise changed by passing it oFer heated magnesium, for after this opera- tion it liquefied and evaporated at a rather higher temperature than previously. It would, therefore, apFear that, whilst atmospheric nitrogen does experience change when passed over heated magnesium, some effect is also produced on chemically prepared nitrogen; and, as far as these experiments have been carried, they reveal no very marked difference between the behaviour of nitrogen from atmospheric air and nitrogen obtained from its compounds by chemical methods.It may be, however, that any conceiitiated impurity boils nearly at t1.e same temperature as the original nitrogen, or that the amoutt pi*esent is so small that it does not liquefy at the temperature of -200" C. Considering that the flasks of 150 C.C. capacity containcd the concentrated impurity of 10 litres of nitrogen, the partial pressui e of small quantities of other matter ought to be very considerable, so that we might itnticipate liquefaction at -200" C. At the lowest terr,- perature reached atmospheric nitrogen which had been passed once over magnesium gave clear, transparent crystals along with liquid, while the untreated nitrogen remained fluid.All the samples of nitrogen and oxygen properly purified, when liquefied in the above manner, are clear, transparent liquids, so that the solid matter which always separates when air or nitrogen or oxygen is liquefied on the large scale consists cf impurities. If a manometer is attached to the flask containing the gas, and at the same time the condensing tube is calibrated, themethod of working gives quantitative results, since the 224 pressure in the flask and the volume of liquid condensed can be simultaneously observed. Further, if we use liquid oxygen as the cooling agent we can observe the vapour pressures of two or more substances at the same temperature, and these pressures may be expressed in terms of the vapour pressure of oxygen.In this way all very volatile liquids would be comparable with oxygen as a standard. If the vapour pressures of the substances are known with snfficient accuracy then the pressure in the flask which has been supplying the gas for lique- faction can be calculated. The following formule are sufficiently accurate, where N and 0 are respectively nitrogen and oxygen pres- sures in centimetres of mercury, and T absolute temperature. 583,sLog. N = 9,0762 -__--T' 626.8 Log. 0 = S.5GS1 ---fll ' th crcf ore 3'> Tiog. -N = 0.5081 + 2.0 'J.' According to the foi-niulE, if the oxygen bath is reduced to 2 cm. pressure, the pressure in the nitrogen flask is 17.8 em., RO that nearly three-fourths of the original mass of gas filling thc flask appears in the liquid state.At the same time it must bc understood that these experiments are merely qualitative, and were not carried out with the riew of separating any new substance from air or nitrogen. Their chief object is to observe the points of condensation and evaporation of gases liquefjing between -1SO" C. and -200" C. at and below atmospheric pressure. Small amounts of known impurities cause marked differences in the amount of liquid formed from the same volume of gas similarly t.reated. Thus a trace of impurity, presumably hydrogen, in a sample of nitrogen subjected to liquefaction in the above manner only gave one-third the volume of liquid that a sirnilax flask gave when filled with pure nitrogen.This is due to the concentration of the hydrogen or other non-liquefiable material in the narrow tube where liquefaction takes place. This plan of working may be con-ceniently applied to testing whether tbe oxygen and nitrogen in air liquefy simultaneously. Such a question cannot be answered by liquefying air under pressure. If, however, two flasks such as have been described are taken, one filled with nitrogen at 0.79 of the atmospheric pressure, and the other with oxygen at 0-21of the atmospheric pressure (the tempera- tures being equal), then on cooling them side by side the instant 225 at which liquefaction takes place in t,he narrow coudensing tubes can be observed. The oxygen always appears a few seconds before the nitrogen, and remains after the latter has ’evaporated. The boiling points of nitrogen and oxygen, under the respective pressures at which they exist in the atmosphere, are very close together.DISCUSSION. The PRESIDEXT,referring to experiments on the liquefaction of gases which he had recently witnessed in the Soya1 Institution Laboratory, said that the means of producing very low temperaturas during long periods, now at Professor Deaar’s disposal there, were marveilouslg complete and important results ought, before long, to flow from their application. It was useless to deny that special interest attached to the com- munication to which they had just listened, but, unfortunately, in the absence of Lord Rayleigh and Professor Ramsay, they were left in the position of having to play “ Hmmlet” with only the ghost present, and, under such circumstances, the play obviously could not be continued to a successful issue.Chemists were deeply interested by the statements relat’ing to the c1iscovei.y of a new con- stituent of the atmosphere, brought, before the British ,Issociation at Oxford, but they awaited furtIber information before making up their minds. They were in a very different position, however. since Friday last, when the President of the Royal Society, in his address, referred to this discovery as the greatest scientific everit of the year. It was to be supposed that the President of the Royal Society had informa- tion at his disposal, not hitherto made public, which justified so definite a statement and naturally chemists would impatiently await its dis-closure.He ventured to say that Lo1.d liaylcigh and Professor Ramsay now could not hope to keep so rcnint*kable a discovery to themselves much longer. After having been told 50 much, chemists could not be expected to remain quiet under the iriiputation that they had been eyeless during a whole century, and they would undoubtedly enquire into the matter. Although no one would seek to take the discovery out of the hands of those wLo Eiad aiiiiouiiced it, chemists unyuestiormbly had the right, not only to clsercise entire freedom of judgment, but also to critically examine the statements which had been made, With regard to Professor Deaar’s observations, which were such as could only be made with the aid of the low temperature appliances at his disposal at the Royal Institution, Professor Dewar would be the first to admit that they were of a qualitative character, and open to several interpretations ; but they were certainly highly suggestive.226 “75. “Onthe use of the globe in the study of crystallography.”By J. Y. Buchanan, F.R.S. The author shows how a globe, on which figures and arcs can be drawn and measured, is serviceable in the study of crystallography exactly as the celestial and terrestrial globes are useful in the study of astronomy acd geography. All the problems to which spherical trigonometry is ixsually applied can be readily solved by graphic con- structions on the globe with an exactness which depends on the size of the globe and the refinement which ha,s entered into its construc- tion, and into that of the divided circles with which the measure- ments are made.Mr. BOURNE, with the aid of lantern slides, described a projective goniometer, independently designed and constructed on the same principle as that advocated by Mr. Buchanan, by Miss Edna Walter and himself, which was exhibited at the Royal Society’s Soiree in June last. A hollow metal sphere is supported on a horizontal axis, while the crystal to be measured is supported on a second axis parallel to and in the same vertical plane as the former. These two axes pass through the centres of two metallic discs of exactly the same circum- ference; the discs are geared together by two steel bands, so that they can rotate at the same speed without backlash, the sphere and crystal moving through the same angle.The discs are fixed to a heavy framework which can rotate about an imaginary vertical line, passing through the centre of the sphere and cutting the two supporting axes at right angles. By means of rotation about its two axes the crystal can be turned into any position whatever, and the sphere moves with exactly the same angular velocity. The two motions are controlled by two convenimt handles. The usual arrazlgement of collimator and telescope is fixed in front of the crystal. A movable leus converts the telescope when required into a microscope, and the crystal can be rotated until any particular face is approximately perpendicular to the line bisecting the angle between collimator and microscope.The microscope lens is then removed, and the cryst’al is finally adjusted till an image of the signal att’ached with collimator is seen to intersect the lens wires in the telescope. In order that the best part of any face may be in the field of view, an adjustment allows telescope and collimator to move either verti- cally or horizontally parallel to the face. When the crystal face is thus in position a cross is printed on the sphere at such a spot that the radius of the sphere through the centre of the cross is parallel to a normal of the crystal face. Each face of the ciytal is seen brought into the same position, and its pole marked upon the sphere.A complete projection is thus obtained, and the angles between the poles can be measured with a graduated arc. The accuracy with which this can be done depends, of course, upon the diameter of the sphere. In this particular instrument the diameter is 6 in., and it is possible to measure to within about 20 min. ’ The working mechanism consists of a small india-rubber staiiip, curved to fit the sphere, and having two fine intersecting raised curves upon it. It rests against a pad soaked with aniline dye and varnish, and moistened with alcohol ; the latter rising through a slide from a tube below. On pressing a lever the stamp moves round. a vertical axis, and presses against the sphere at, the right spot.”76. “ A new method of obtaining dihydroxytartaric acid, and the use of this acid as a reagent for sodium.” By H. J. H. Fenton, M.A. In n former communication a new acid was described, which is obtained by oxidation of tartaric acid in presence of iron. The formula of this acid is CaH,Os. It is dibnsic, and crystallises with 2Xf,0. The molecule of this crystsllised acid corltains, therefore, two atoms of hydrogen more than that of diliydroxytartaric acid, and it is now shown thst it readily yields the latter acid on oxidation. If bromine be employed as the oxidising agent, the change takes place quantitativeiy, according to the equation C,H,O,*ZH,O + Brz = C,HsO, + 2HBr. The solution so obtained gives a white, crystalline precipitate of the nearly insoluble sodium salt when neutralised with sodium carbonate.The yield of sodium salt does not fall far short, of tlie theoretical. From this salt, the free acid is easily obtained by Miller’s method (Bey., 1889, 2015). Since free dihFdroxgtartaric acid can be so readily obtained in this way, the author suggests its use as ;I, reagent for the detection of sodium. The test is fairly delicate, and does not appear to be influenced by the presence of potassium or ammonium salts. *77.“Essential oil of hops.” By Alfred C. Chapman. In a preliminary communication to the Society (Proc., 1893, 177) the author gave a brief account of a sesquiterpene prepared from the essential oil of hops by fractional distillation.Since then three othei- and much larger samples of the essential oil have been more fully examined with more definite results. All of these samples are of known origin and genuineness. The relative densities and specific rotatory powers having been determined, these samples of oil were submitted to fractional distillatioiz under a pressure ol 60 mm. of mercury, the fractions of corresponding boiling points being i-nixecl aftw their identit]y had been ascertniced. After prolonged frnctionRtion the following fractions were ohtsined. (1) 86-91" ; (2)145-1.50' ; (3) 163-168" ; (4) 168-1733'. Nos. 1and 4 were the main fractions, the remaining two being small. Fraction No. 4 corresponded to nearly two-thirds of the oil 11 sed. These fractions were then submitted to a careful investigation.Fraction No. 1 was a colourless, mobile liquid, of characteristic smell. After purification by distillation over sodium under a pressure of 50 mrn. it boiled at 86-89" at atmospheric pressure ; b. 13. 16ci-171", rising afterwards to about 2$0" owiiig to polymerisation and oxidation. Its relative density at 20°/2Uo was 0-799,and it was optically inactive. On combustion it gave numbers closely agreeixg with the foi*mula C,,,H,,; its vapour density also agreed with this formula. Hydrogen chloride was readily abwrbed by this fraction, forming an oil which was, in all probability, a mixture of two distinct hydrochlorides. Attempts to prepare a nitrosochloride, a nitrosate and a nitrositc fkom this fraction failed.ItJwould appear to consist of two hydro- carbons, Cl,H,, and C,,HIS. The latter is probably tetrahydrocymene (b. p. 167"), whilst the former may be one of the " olefinic terpenes " dcscribed recently by Semmler. It is at least certain that the greater part, if not the whole, of the lower fraction consists of hydrocarbons other than the ordinary terpenes. Fraction No. 2 (145-150") occurred in such small quantities that its complete identification was not possible. It was a colourless oil having a pleasant s-me11 of oil of geranium, with an after-smell of oil oE rue. Tt did not solidify at -10'. Its relative density at 15"/15" was 0.885, and, on analysis, it gave numbers agreeing with those re-quired for the formula C,,H,,O. It united readily with bromine, and in many of its properties appeared to bear some resemblance to geraniol.Fraction No. 3 (163-168') was a small iraction which was found to be a mixture of Fractinns 2 and 4. Fraction No. 4 ( 168-173") was by far the largest. It consisted of a sesquiterpene, C1,H2,; the following are its chief properties. Boiling point, 263-5266" (corr.) ; reiativz density at 15"/15" = 0.9001 ; molecular refraction 66.8, a sesquitcrpene with two pairs of " doubly-linked " carbon atoms requiring 65.7 ; it was optically inactive, and unites with 4 atoms of bromine to form an oily bromide. The dihydrochloride could not be crystallised. With nitrosyl chloride it unites, forming a white, crystalline nitrosochloride melting at 164-163". With piperidine this nitrosochloride reacts readily, forming a crystalline nitro1 piperide melbing at 153".This sesqiiiterpene is not identical with either culnebenc (cndincnc), 229 cargophyllene, clovene, or cedrene, the only four sesquiterpenes of which we possess any definite knowledge, and it is therefore pro-posed to name it "humulene." In three out of the four samples of oil examined humulene was the main constituent. 78. " Interaction of 1 :2-diketones with primary mines of the general formula R'.CH2-NH2. Second notice." By Francis R. Japp, F.R.S., and W.€3. Davidson, M.A., B.Sc. In a previous note on the interaction of benzglamine and bend in presence of zinc chloride (Proc., 1894, as), the authors showed that these substances yield tertiary and quaternary benzyl-deriva- tives of lophine.The present cominunication deals with results obtained in the study of analogous interactions. Renzil and ethylamine interact according to the equation yielding X-ethy I-dipheny1-,u-methy 1-imidazole, which forms lustrous prisms melting at 125.5". When zinc chloride is present, a chlo-ride of a quaternary base appears to be formed at the same time, as in the benzylamine interaction, but was not isolated in a state of purity. The constitution of the foregoing irnidazole was proved by preparing it by the action of ethyl iodide on diphenyl-p-methyl-irnidaxole. It also unites with ethyl iodide to form a quaternary The action of methylamine on phenanthraquinone has been studied by Zincke and Hof (Bey., 12,1644), who obtained a base to which they assigned the formula C]6HI4NZ.The present authors find, how-ever, that the formula is C,,H12N2. The compound is formed in an iiiteractioii strictly analogous to that which occurs with benzyl and ethvlamine, and its constitution is doubtless that of N-methyl-11el Ly1ene-imidazole, ?6H4'g*N(CH3)>CH.The melting point wasdi~? CsH,*C-N found at 188" (185-186", Zincke and Hof). Phenanthraquinone and benzylamine yield dipkenyZeize-tL-pher,yl-mazole, whilst, at the same time, a sparingly soluble compound of high melt- ing point is formed, which appears to have the formula C,BH,iNO, but, is difficult both to purify and to analyse. 230 79." The isomeric dinitrodiazoamidobenzenes and their melting-points." By R. Meldola, F.R.S., and F. W. Streatfeild. The authors have made a careful series of comparisons between their former preparations of diparadinitrodiazoamidobenzene and specimens placed at their disposal by Drs. Pawlewski and Bamberger. They find all three products to be identical, and have come to the conclusion that in this case there is no reason to suspect stereo-chemical isomerism in the sense advocated by Hantzsch. The dis-crepancies in the melting points given by different observers has been found to be due to the circumstance that the compound has no definite melting point, but a point of decomposition, as they had already stated in former papers. They have found that the pure compound can be made to melt at 220--236", according to the rate at which the thermometer is raised. The hitherto unknown diortho- compound, (o)N~~.C~H~*N~H*C~H~.N~~(O),has been prepared, and consists of golden-jellow scales melting without decomposition at 196-196.5'.This compound has all the properties of a true diazo- arnide ; it is acid in character, and forms salts which are somewhat unstable. The " protecting influence " of the nitro-group in the ortho-position renders the formation of alkyl ethers diEcult, if not altogether impossible, and the authors have not jet succeeded in alkylating the compound. 80. " On the yellow colouring matter of ' Sophora japonica.' " ByEdward Schunck, Ph D., F.R.S. The undeveloped flower-buds of Sopho,<ajupmiictb, a leguminous plant growing in the North of Cliina, contain a yellow colouring matter which has been examined several times without any definite conclusion having been arrived at.Foerster, considering it as a pecu-liar substance, called it snphorin, but the author's experiments show that it is identical with rutin, the colouring matter of garden rue and other plants. It yields, on hydrolysis, quercetin and rhamnose The numbers obtained by analjsis corresponded with the formula C27H32016,in accordance with which its decomposition by hydrolysis would be represented by the following equation : C2,H3& + 3KO = CiSHioO7 + 2CsHi,Q,. Herzig's formula, Cl5H,,Oi, was adopted as representing the coiii- position of querce tin.231 ADDITIONS TO THE LIBRARY. I. Donations.
