Abstract
PARIS.Academy of Sciences, July 5.—Gabriel Bertrand and M. Mâchebœuf: The influence of nickel and cobalt on the action exercised by insulin on the dog. The results of experiments carried out on the rabbit have been given in an earlier communication: it is now shown that the addition of cobalt and nickel to insulin causes similar effects on the dog and rabbit. There is an increase in activity in both animals; cobalt has a greater influence than nickel.—Gaston Julia: A series of polynomials connected with the conformal representation of simply associated areas.—Luigi Fantappiè: Analytical functionals which are functions of a finite number of linear functionals.—René Lagrange: Legendre functions of the first species and certain associated fanctions.—N. Gunther: The movement of a liquid filling a. simply associated domain which is displaced.—Henri Bénard: The deviations of the values of the frequency of vortices alternating with respect to the law of dynamical similitude.—Th. De Bonder and Fr. H. van den Dungen: The quantification deduced from Einsteinian gravific.—Léon Brillouin: The undulatory mechanics of Schrodinger; a general method of resolution by successive approximations.—W. H. Keesom: Solidified helium (v. NATURE, July 17, p. 81).—Jean Lecomte: Infra-red absorption spectra of cyclic derivatives. The infra-red absorption spectra of derivatives of benzene, cyclohexene, and cyclohexane have been compared and numerical data are given.—Rene Lucas: The rotatory power of tartaric acid. The effects of the addition of such substances as boric acid, tungstic acid, urea, etc., can be explained as being due to the appearance of one new form, strongly dextrorotatory, and in proportions varying with the reagents. It is possible that the anomalies of malic acid follow a similar mechanism.—P. Daure: The qualitative study of the fluorescence of bromine vapour.—R. de Mallemann: Magnetic rotatory dispersion and the dispersion of electric double refraction. From theoretical considerations it is concluded that the ratio of Verdet's constant to Kerr's constant should vary inversely as the wave-length, or, alternatively, the ratio of the magnetic rotatory dispersion to the dispersion of electric double refraction should be equal to the corresponding ratio of wave-lengths. This conclusion is verified experimentally for carbon disulphide and for camphor in hexane solution.—Paul Gabriel Girault: A possible influence of commutation on the stability of continuous current machines.—Georges Fournier: The absorption of β-rays by matter.—D. P. Konovalov: The heats of combustion of some hydrocarbons. Values are given for the heats of combustion of cyclohexene, methylene-cyclohexane, and dicyclohexane and the figures compared with those calculated from a formula given by the author in an earlier paper.—A. Boutaric and G. Corbet: On the critical temperature of solution of acrolein and water and on the molecular mass of soluble acrolein resin. The soluble acrolein resin studied is a polymer of ten molecules of acrolein.—Surun: The estimation of the adsorbing power of carbons.—E. Rouyer: The determination of some double salts in solution by the boiling point method. Experimental data for the double sulphate of ammonium and RSO4, where R is cadmium, iron, cobalt, manganese, zinc, magnesium, copper, and nickel, and also double chlorides of the carnallite type.—Holweck: The spectrometry of the K series of the light elements. The K discontinuity of fluorine. The advantages of the method of critical potentials are emphasised; it brings out the K discontinuity of fluorine at 684.2 volts very clearly. By combining the results of several workers, the Moseley curve from helium to sulphur is shown to be a straight line.—V. Ipatief and A. Andreevsky: The displacement of platinum by hydrogen under high pressures. The precipitation of platinum from its solutions by hydrogen is a function of the temperature, pressure, concentration, and time, and results of experiments in which each of these factors was varied are given. The presence of metals such as iron and nickel, especially in acid solution, tends to retain platinum in solution.—Daniel Florentin: The estimation of soluble silica in cements, mortars, and concretes.—Georges Denigès: The action of concentrated hydro-bromic and hydriodic acids on the cobalt ion. A new reaction for nickel. A description of new colour reactions of cobalt with concentrated hydrobromic and hydriodic acids and of nickel with concentrated hydriodic acid.—André Job and Antoine Cassal: The fixation of carbon monoxide on an organic magnesium compound by means of chromic chloride. A solution of phenylmagnesium bromide is without action upon carbon monoxide, but the addition of anhydrous chromium chloride causes an immediate absorption of the gas. From the products of this reaction benzopinacone, benzophenone, benzhydrol, diphenyl, diphenyl-acetophenone, and benzaldehyde were isolated. Some chromium-carbonyl is also produced.—Marcel Delépine: A supposed isomer of methylene-amino-acetonitrile. Methylene-bis-imino-diacetonitrile. The substance previously described as an isomeride of methylene-aminonitrile is proved to be the methylene derivative of imino-diacetonitrile.—Emile Votoček and F. Valentin: The optical inverse of natural rhamnose. Starting with isorho-deonic acid, d-rhamnose has been prepared; it has all the properties of natural rhamnose except that its rotation is of opposite sign.—F. Salmon-Legagneur: The action of ethyl-magnesium bromide on the methyl ether of the α-mononitrile of camphoric acid. The products of the reaction are α-ethylidene-camphidone and a secondary nitrile alcohol.—Octave Bailly and Jacques Gaumé: The synthesis and hydrolysis of glyceromonophosphoric di-ester; αβ-diglyceromono-phosphoric acid and the constitution of orthophosphoric acid.—René Delaplace: The preparation of caesium eosinate. Cæsium hydroxide is treated with the theoretical quantity of acid eosin to prepare the eosinate. Details are given of the preparation of the eosin and of the cæsium hydroxide, together with the method of recovering the cæsium.—Viret: New observations relating to the rodent fauna of Saint-Gérand-le-Puy.—Mile. G. Bonne: The nature of the floral section in the Chrysobalanee.—M. Bridel and C. Béguin: A new glucoside, hydrolysable by rhamno-diastase, extracted from the fresh flowers of Ulex europæus. Details of the extraction, chemical and physical properties of a new glucoside, to which is given the name ulexoside. This gives the methyl-pentose reaction, and can be hydrolysed by rhamno-diastase giving a sugar and ulexogenol.—A. Sartory, R. Sartory, and J. Meyer: The study of the action of radium on Aspergillus fumicatus in culture on dissociated and non-dissociated media.—M. and Mme. A. Chauchard: The action of curare on the electrical apparatus of the torpedo (Torpedo marmorata). The curarisation of the electrical apparatus of the torpedo necessitates the use of relatively large doses of curare. The poison does not act on the nerve but on the electrical organ.—G. A. Nadson and M. N. Meisl: The mechanism of the action of chloroform on living matter. Description of the action of chloroform on a yeast (Saccharomyces Ludwigii), the observations being so arranged that the same cell was studied throughout.—Pierre Girard and Edouard Peyre: The suppression of shock and modification of the anaphylactic sensibilisation by certain fluorescent colouring matters.
