Abstract
PARIS Academy of Sciences, March 25 (C.E., 200, 1077–1160). ROBERT LESPIEATT and PAUL HEITZMANN: The C8H4 hydrocarbons arising from the action of crotyl bromide upon its magnesium derivative. Three isomers have been isolated from the product of this reaction: their probable constitution is indicated. GASTON FAYET was elected a member of the Section of Astronomy in succession to the late Benjamin Baillaud. JEAN LEBAY: The topology of the abstract spaces of M. Banach. JEAN DELSABTE: The application of a general principle of development of the functions of a variable to the series of Bessel's functions. K. NIKOLSKY: The electromagnetic field of Dirac's electron. EDGAR PIEBBE TAWIL: Considerations on the development of electricity by quartz. The electricity developed by the torsion of quartz is named strephoelectricity, and reasons are given for regarding this as distinct from piezoelectricity. ALBERT MILHOUD: The electromotive force produced by the outflow of steam. Study of the effects on the electromotive force of the presence of traces of electrolytes in the drops of water in the steam jet. J. CAYBEL: Remarks on the energetics of thin plates placed in the midst of a polarisable medium. ROBERT BOSSUET: The quantitative spectrographic analysis of the alkali metals. Application to caesium in mineral waters. The salts are volatilised in an oxyacetylene flame and the dilution determined at which the line 4555-3 vanishes. Figures are given for the caesium found by this method in ten French mineral springs. JEAN TEBBIEN: The absorption and fluorescence of the vapours of the cuprous halides. CHARLES LAPICQTJE: The distribution of light in the retinal image of a distant point. MABC ANTOINE FOEX: The application of electrical conductivity to the study of separations in fused glasses. CHARLES DUFBAISSE and MABITJS BADOCHE: Relations between the optical properties of the medium and the photochemical constants of tetraphenylrubene. Individual influence of the chemical nature of various solvents. The chemical nature of the solvent exerted a marked influence on the oxidation velocity. MLLE. PAULETTE BEBTHIEB: The role of evaporation in the phenomenon of imbibition presented by porous bodies. PIEBBE DUBOIS: The decomposition of permanganic acid and of manganese peroxide. Details of the precautions necessary during the preparation of the peroxide to obtain pure MnO2. ANDBE MOBETTE: A new method for the preparation of pure vanadium. Metallic vanadium containing more than 99 per cent of the metal can be prepared by the action of magnesium on vanadium tetrachloride or dichloride at 700°-800° C. Y. RE:NE NAVES, GEOBGES BBUS and JEAN ALLABD: Contribution to the study of the citronellol-rhodinol isomerism by means of Raman spectrography. Comparison of alcohols obtained from various sources and carefully purified. DANIEL GABDNEB, MICHEL PBOCOFIEF, GEOBGES Jusov and MARIA LUCIANA CASELLI: The synthesis of carvacrol. Description of a complete synthesis of carvacrol, starting with paracymene. A second method is from orthocresol and isopropyl alcohol, by treatment with phosphorus pentoxide. MME. NELICIA MAYEB: The composition of solutions of glucides after treatment with alkali. RAYMOND PAUL: Oxidation and reduction phenomena observed in the catalytic dehydration of the furylalkylcarbinols. PAUL GAUBEBT: Modification of the facies of crystals of phloroglucinol by colouring matters, and the action of heat on the coloration. G. CHOUBEBT: The enclosures of some lodes in the neighbourhood of Bresse (Vosges). MME. ODETTE THELLIEB: Simultaneous measurements of various elements of atmospheric electricity. V. GBEGOIBE: New data on the morphogenesis of the leaf axis in the Dicotyledons. FEBNAND O BATON: The biological behaviour of Sterigmatocystis Phcenicis compared with that of Sterigmatocystis nigra. PAUL Riou and JOACHIM DELOBME: The presence of manganese in maple sugar and in cane sugar. MLLE. E. LE BBETON, MAUBICE NICLOUX and GEOBGES SCHAEFFEB: The coefficient of ethyl-oxidation and basic metabolism in some homeotherm species. NICOLAS T. KOBESSIOS, HENBI TILLE and JEAN CHASSANG: Comparative studies on certain physiological effects of cobra poison, filtered and unfiltered. The best conditions for experimenting with venoms. MARCEL GESLIN: Contribution to the study of the argon-nitrogen ratio in natural gases. Gases arising from the natural destruction of animal or vegetable organisms show a ratio of argon to nitrogen lower than that found in air. This is attributed to the nitrogen evolved from the animal or vegetable matter. J. ANDRE THOMAS: The vitellin entoblast behaves in vitro as a merocrine gland secreting a product comparable with the vitellus. ETIENNE RABAUD and MLLE. MARIE LOUISE VER-RIER: The ablation of the swim bladder of the Physostome fishes. MLLE. DINAH ABRAGAM: The specific curves of discharge of normal and cancerous animal tissues charged electrically. CHARLES DHERE and MLLE. ANNE RAFFY: The infra-red radiation emitted by the fluorescence of green leaves when illuminated. J. WAJZER: The static interfacial tension as a function of the concentration of alkali in the saponification of oil. MME. ANDREE DRILHON: The alkaline reserve, the pH. and moulting in the short tailed Crustaceans. HENRI VIOLLE: The action of sodium ricinoleate on various microorganisms. Various strains of human and bovine tubercle bacillus, and various types of Spirochseta, were killed by contact with weak solutions of sodium ricinoleate. At similar concentrations, various diastases were unaffected. FRANÇOIS MAIGNON: Researches on the mechanism of anaphylactic sensitisation. RENE LERIOHE and RENE FONTAINE: The present state of knowledge concerning peri-arterial sympathectomy, after 546 operations.
