Abstract
PARIS Academy of Sciences, July 23 (CM., 199, 249-328).—CH. POBCHEB, HENBI VOLKBINGEB and MLLE. JEANNE BBIGANDO: Contribution to the study of casein. Detailed study of the absorption spectra, of casein and paracasein. EDOUARD CHATTON and MLLE. BERTHE BIECHELER: The Coccidinidae, dino-flagellate coccidiomorph parasites of Dinoflagellates and the phylum of the Phytodinozoa. MARC KRASNER: The first case of Fermat's theorem. A. GELFOND:—Some new results in the theory of transcendental numbers. JEAN MASCART: The perihelia of the minor planets. HENRI MINEUR and HENRI CAMICHEL: The variations of the ellipsoid of velocities in the galactic plane. HANS EKSTEIN and MICHEL MAGAT: Remarks on the forces of Van der Waals in liquid mercury and in the molecule Hg2. GEORGES DECHENE: The Johnsen-Rabbeck effect. The author gives a new explanation of this phenomenon which also affords an explanation of an experiment described by Toby. DANIEL BODBOUX and RENE RIVAULT: Some attempts to photograph the television emissions from London and a local station on short waves. Description of the apparatus used for the reception with reproductions of the photographs obtained. ANTOINE GOLDET and ARCADIUS PIEKARA: The thermal variation of the magnetic double refraction of mixtures. The case of a mixture presenting a critical point. L. COLOM-BIER: The electrolytic potential of nickel. Values varying between 0-138 and 0-621 have been published for this constant. The author discusses the possible causes of this variation and describes experiments in which the errors due to gases fixed on the surface of the nickel and to the increase of activity due to the presence of hydrogen are eliminated as far as possible. The values found fall between? 0-225 and 0-23. ANTOINE MARSAT: The modes of graphical representation of the distribution of the flux emitted by a light source. JEAN PAUL MATHIEU: The optical activity and solubility of some cobaltammines. PRIVAULT: Weak lines of the K series of the elements from chromium to copper. The fluorescence lines of some compounds of these elements. F. HAMMEL:—The X-ray spectra of manganese sulphate and its hydrates. Five specimens of the monohydrate of manganese sulphate prepared in different ways give the same spectrum: nothing in the spectra of the five specimens suggests a difference of structure. These results are not in agreement with those of Krepelka and Rejha. I. ZLOTOWSKI: The heat of the y-radiation of radium. An application of the adiabatic microcalorimeter of Swietoslawski and Dorabialska. MARITJS BBIAND, PAUL DUMANOIS and PAUL LAFFITTE: The influence of temperature on the limits of inflammability of some combustible vapours either pure or in admixture. Data are given for isopentane, acetone, methyl, ethyl and butyl alcohols and some binary and ternary mixtures. MME. ALMA DOBBY: The osmotic pressure of polymerised substances. Utilising an apparatus capable of measuring with sufficient accuracy osmotic pressures down to 1-5 mm. of water, the limiting value of the ratio pressure to concentration can be determined. These limiting values are independent of the solvent. The molecular weight of nitrocellulose thus obtained is 110,000. MABCEL CHATELET: Some reactions of divalent chromium chloride. Compounds of chromous chloride with pyridine and with ammonia. HENBI VOLKBINGEB, ABAKEL TCHAKIBIAN and MME. MABIE FBEYMANN: The Raman spectra of the metallochloroforms in relation with their structure. Comparison of the Raman spectra of chloroform, silicochloroform, germanochloroform and chlorstannic acid. The correspondences show that these four compounds have analogous structures. MLLE. BLANCHE GBEDY: The (Raman) spectra of some acetylene compounds of the cyclane series. LEON PALFBAY and MLLE. SUZANNE TALLABD: The influence of the free acidity on the determination of aldehydes and ketones by hydroxylamine hydrochloride. The amounts of aldehyde or ketone found by the hydroxylamine method are affected by the presence of organic acids, but this error can be minimised by the use of bromo-phenol blue as indicator. RENE EMILE BBEUIL: Complex compounds of ferrous salts with ethyl-enediamine and trimethylenediamine. CAM. LEFEVBE and CH. DESGBEZ: Contribution to the study of the aromatic sulphides. F. LINK: The illumination of the higher atmosphere and the twilight tables of Jean,Lugeon. J. LACOSTE and J. P. ROTHE: Earthquakes in France in 1930-33. ANDBE DATJPHINE: The mode of formation of the pecto-cellulosic membrane. P. MARTENS: New observations on the cuticle of floral epiderms. MATJBICE PIETTBE: Concerning the protein equilibrium of the blood serum. SEBASTIEN SABETAY and MME. HEBMINE SABETAY: A colour reaction of the azulenogen sesquiterpenes. A. LEPAPE and R. TBANNOY: The influence of radium on the cultural yields of some plants. J. E. ABELOUS and R. ABGAUD: The formation of adrenaline in the suprarenal capsule. Combined or virtual adrenaline and free adrenaline. PAUL MATHIAS and MME. MABGTJEBITE BOUAT: The development of the egg of Branchipus stagnalis, a phyllopod crustacean. MLLE. A, TETBY: Description of a French species of the genus Pelodrilus. W. KOPACZEWSKI: Seric lacto-gelification considered as an index of neoformation. LEON BINET and MLLE. MADELEINE BOCHET: An arrangement for artificial respiration in man.
