Abstract
PARIS Academy of Sciences, July 1 (CM., 201, 1-104). LOUTS BLARINGHEM; The duplication of the flowers of tho wallflower (Cfwirantkus Cheiri). JEAN REY: The energy yield of thermo-compressors. Definitions and values. The efficiency of a thermo-compressor can be defined in six ways, all rational. The values differ, and if the compressor is bought under guarantee, the exact definition of field must be specified. H, GRUYELLE and CHARLES POISSON: The magnetic anomalies of the crystalline massif of Madagascar. The magnetic survey by E. Colin between 1901 and 1906 gave magnetic charts of great comploxity due to the presence of anomalies. These are now shown to be very local and are mainly due to the presence of magnetite in certain of the underlying rocks. ANDRE CARREL and CHARLES A. LINDBERG: The culture of entire thyroid glands. The thyroid gland, with its epithelial cells, its conjunctive tissue, arteries and veins, continues to live for at least 20–30 days under the conditions described in these experiments. Its structure, the structure and activity of its follicles vary rapidly with the chemical composition and the physical and physico-chemical conditions of the liquid circulating in the vessels. WALTER S. ADAMS was elected CorrespontkmL for the Section of Astronomy in succession to the late F. Connessiat. PIERRE DAURE: Remarks on the validity of statistical conceptions applied to social phenomena. GAKRETT BIRKHOFF: Discrete spaces. RAYMOND JACQUES: Certain systems of partial differential equations. ALFRED ROSENBLATT: The Green's function of a limited domain of Euclidian space of three dimensions. M. KREIN: ‘Charged’ integral equations. W. BRECKA; Multiply monotonic polynomials which deviate least from zero. FREDERIC ROGER: Some metric applications of the idea of the bilateral contingent. LARS AHLFORS: The type of a Riemann surface. ALBERT TOUSSAINT and MIROSLAV NENADOVITCH: Contribution to the study of certain rigid biplane cells of finite span. MAURICE DENIS: Contribution to the experimental study of sustaining wings at large incidences. E. M. ANTONIADI: Recent observations of the planet Mars with tho 83 cm. telescope of Mcudon observatory. The appearance of Mars shows no great difference from that shown in 1933. Details of the observations are given. FREDERIC MARGUET: The curve of equal azimuth and its use in navigation. GEORGES ALLARD: Statistical mechanics and the equilibrium of radiation and of matter. ANDRE LEAUTJ£: The measurement of the surface tension of viscous substances such as tars and bitumens. Studies of the capillary tube method, paying special attention to the time necessary to attain equilibrium, one bitumen requiring 360 hours. Discussion of the causes of the large divergences between the results obtained by this and by other methods. CLAUDE CHARMETANT: The electrolysis of nickel and cobalt chlorides in solutions of mixtures of water and ethyl alcohol. HUBERT FORESTIER: Magnetisation, at a high temperature of ferromagnetic powders. Powders (precipitated ferrites, oligist) heated to the temperature of the Curie point and cooled in a magnetic field show-ed residual magnetism. This is now shown to depend on three fundamental factors, strength of the field, fineness of the grains, and the crystalline structure. NICOLAS SZTTLC: Study of the structure of the electric arc. From the results of the experiments described it is concluded that the electric arc is divided into two parts: a conducting part where tho electrical energy is partly used in producing dissociation of exothermic compounds and the formation of endothermic compounds, and a slightly conducting part where exothermic compounds are formed. HTJA-CHIH CHENG and JEAN LECOMTE: The modes of vibration of the 1,2,dihalogen derivatives of ethane. The results tabulated are based on Raman spectra and maxima of infra-red absorption. MICHEL DUFFIEUX: The phosphorescence of nitrogen peroxide. The intensity of the bands of the second positive group of Ns. STEPHAN PROCOPHJ: The depolarisation of light by colloidal solutions, by crystalline precipitates and by solid deposits on glass. MAURICE LTJCAS: The variation of the length of cement as a function of the hygrometric state of the air. The experimental results are given graphically in three curves, showing the change of length as a function of the weight of water absorbed, and as a function of the hygrometric state of the air, and the change of weight as a function of the hygrometric state of the air. JEANMOLNAK; The physicochemical properties of picric acid in the pH. scale. The experimental results can be explained on the hypothesis that picric acid passes through seven molecular forms with changing pH. PIERRE JOLIBOIS and FRANCOIS OLMER; A new method of catalysis. Application to ammonia. ANDRE MICHEL and ANDRE GIRARD: Thermomagnetie analysis as a means of proving the existence of weak solid solutions of the oxides of iron. F. BOUBION and K. ROUYER: The cryoscopic determination of the total hydration of the ions of magnesium chloride. JEAN BUREAU: The system calcium nitrite, water. MLLE. MARIK FALINSKI: The increase in the rotatory power of mannite by zirconium salts in aqueous solutions. MARCEL PATRY: The telluric acid group. Nomenclatures. T. KARANTASSIS and L. CAPATOS: The complex iodine compounds of divalent germanium. ORESTE MILLER and LEON PIAUX: The Raman spectra of meta- and para-dimethylcyclohexane ds and trans isomers, ami of 1,1,dimethylcyclohexane. CONSTANTLY GRKOBGIU and MLLE. LUCIE MANOLESCU. Heteropolar combinations: complex salts of silver and mercury with 2,thio-4-hydroxy-1,2,3,4-tetra-hydroquinazoline. CHARLES LAPP: The specific rotatory power of salts of quinine, quinidine, cin-chonine and cinchonidine. PATTL BRENANS and PIERRE LARIVAILLE: Todo-m-nitrophenols. EDMOND ROCQUIER: The existence of a group of large fossil cavities of the Monasterian epoch on the coast of Talmondais (Vendee). V. BABET and RAYMOND FURON: The continental post-Hercynian formations of the west of Africa (western Africa and equatorial Africa). MAURICE GENCE: The bases of the Klippes of Etienne-Eneauron, to the north of Sainte-Baume. GEORGES DKSIZOT: The successive tectonic phases in the neighbourhood of Marseilles. PIERRE TJRBAIM: The separation of the various constituents of marls.
