Abstract
PARIS Academy of Sciences, November 25 (CM., 201, 997–1072). LUCIEN DANIEL: An accidental crossing of the bean. A detailed account of a hybrid bean, the descendants of which do not appear to be in agreement with the Mendel scheme. DIMITRI RIABOUCHIN-SKY was elected Correspondant for the Section of Mechanics in the place of the late M. de Sparre. NICOLAS KRYLOFF and NICOLAS BOGOLIOUBOFF: Some theorems of the general theory of measure. PAUL VINCENSINI: The curvature of congruences of spheres. ENRICE BOMPIANI: A system of curves of a surface invariant by projectivities. D. VAN DANTZIG: The idea of the derivative of a functional. DAVID WOLKOWITSCH: The theoretical problem of balancing rotating parts. ALFRED ROSENBLATT: Certain classes of movements symmetrical with respect to an axis of an incompressible viscous liquid. ANDRE AUBIC: A cosmogonic hypothesis. CHARLES VALLOT: A new map of the Mont Blanc massif by Henri, Joseph and Charles Vallot on the scale of 1:20,000. PIERRE MARTI: A gravimetric cruise of the submarine Fresnel in the north-west part of the Mediterranean basin in 1933–34. Work done with the Vening-Meinesz apparatus for the determination of g at sea on the coasts of France, Spain, Corsica and the Balearic Islands. An outline of the results, with a chart, is given: a full account of the results will be published elsewhere. REZA RADMANECHE: The action of the ultra-violet rays on the electrical conductivity of quartz. The experimental results are summarised in a diagram. MAURICE LAMBREY: A system of transformation with logarithmic argument for continuous current. JEAN LAGRULA: An error in photographic photometry. Discussion of the effect of the inequality of the surfaces of the photographic plates and means of avoiding the errors thus produced. Louis D'OR: The absorption spectra of sulphur vapour. The author concludes from his experiments that sulphur vapour contains at least four species of molecules, excluding The spectrum described by Graham, Dobbie and Fox, and by Rosen is not due to S8 (Graham) or S2 (Rosen) but to an.intermediate molecule, probably S4. JEAN TERRIEN: The rotation structure of the D and E systems of bands of cuprous chloride. MICHEL KANTZER: The influence of pressure and of foreign gases on the optical absorption of chromyl chloride. A. VILA and F. TESSON: The measurement of the mechanical properties of plastic films. JACQUES BANCELIN and YVES CRIMAIL: Substances inhibiting the corrosion of iron by acids. A comparison of the effects produced by the addition of rhodamine and of thiourea to the acid solution showed that whilst the anti-corrosion effect of rhodamine increased with the concentration, there was a certain concentration of thiourea for which the corrosion of the iron was a minimum. 0. BINDER: The decomposition of pentahydrated copper sulphate by heat. Crystallised copper sulphate heated to 650° C. gives a basic sulphate 2CuO.SO3, proved by chemical analysis and by a study of the X-ray spectrum to be a definite compound. EMILE CARRIERE and MLLE. LUCY FAYSSE: The comparative action on sodium thiosulphate of oxygen compounds of chlorine and of the corresponding oxygen compounds of iodine. JOSEPH MAGROU: Attempts at the culture of mycorrhizal fungi. ANTOINE DE CUGNAC: Remarks on the meaning of certain polymorph species in the Graminese. PH. JOYET-LAVERGNE: The relations between vitamin A and the plastids. The author concludes that vitamin A is an essential constituent of the chondriome, and this is verified for plastids in the course of their evolution. MLLE. GILBERTE MOUBOT: Nitrogenous metabolism in protein starvation. DAVID URCHIN and HERMANN SCHEINER: The physico-chemical state of acetylcholine in the blood. E. LEVY-SOLAL and M. SUREAU: Graphical study of the work of accouchement. RAYMOND HAMET: A new true sympathicolytic: Koepfli's rauvolfine. BERNARD TROUVELOT and GRISON: Variations of fertility of Leptinotarsa decemlineata with the tuber producing Solanum consumed by the insect. Experiments with six species of Solanum showed that the fertility of the insect varied considerably with the species of plant. ETIENNE WOLFF: The experimental transformation of genetic females into intersexuals, produced by the injection of male hormone into fowl embryos. Intersexuality can be obtained regularly in the embryo of the fowl by androsterone injection of genetically female individuals. A. GTJILLATJME and G. TANRET: The hydrolysis of the glucosides and of some organic compounds by ultra-violet rays. The ultra-violet rays possess a clear hydrolysing action, especially marked with glucosides and esters. ROBERT BONNET and MLLE. BERTHE NATAF: The destruction of certain hydrolysing diastases in the course of their action. Seven diastases were studied, and all showed decreased activity with time. It is concluded that there is a real autodestruction of the enzyme. ANDRE PAILLOT: A new ultra-virus parasite of Agrostis segetum causing a proliferation of the infected tissues. AUGUSTE TRILLAT: Attempts at vaccination for fowl cholera. MAURICE LEMOIGNE, PIERRE MONGUILLON and ROBERT DESVEAUX: The characterisation of hydroxylamine in autolysed green leaves.
