Abstract
PARIS Academy of Sciences, December 2 (CM., 201, 1073-1156). HENBI DOUVILLE: Notice on the work of the late H. F. Osborn, Correspondent of the Academy. ALEXANDBE GUILLIEBMOND, MAUBICE FONTAINE and MLLE. ANNE RAFFY: The existence in Eremothecium Ashbyii of a yellow pigment belonging to the flavin group. The pigment from the Eremothecium has been directly compared with Karrer's lactoflavin and shown to possess similar properties. It is suggested that the pigment may play an important part in the metabolism of these fungi. JULIEN COSTANTIN: The enroulement of the Belle de Juillet variety of the potato. Remarks on the favourable effects of high altitudes on this disease. CHARLES PEBEZ was elected a member of the Section of Anatomy and Zoology in succession to the late Louis Joubin. KABOL BOBSTJK: Contribution to the theory of dimensions. P. RACHEVSKY: A dual bimetric system. SEBGE FINIKOFF: Stratifiable couples attached to surfaces the asymptotics of which belong to linear complexes. SZOLEM MANDELBBOJT: The J right lines and singular points of functions represented by Dirichlet's series. R. O. KUZMIN: The method of Tschebicheff for the approximate evaluation of integrals. JEAN LAGBULA: The intensity of gravity in Algeria, in the Midi of France and in the island of Majorca. Tables of results obtained during 1935 with the Holweck-Lejay pendulum. SANTIAGO ANTUNEZ DE MAYOLO: The interpretation of the a coefficient of fine structure. JACQUES YVON: The fluctuations of the density at the critical point. Discussion of a theorem of Smolu-chowski from the point of view of the effect of gravity. PIEBBE VEBNOTTE: Concerning a problem of convection: insufficiency of the equation of heat. JEAN MEBCIEB: The determination of the region of synchronisation of two oscillators. JEAN BEBNA-MONT: The fluctuations of potential at the boundaries of a metallic conductor of small volume traversed by a current. MABCEL LAPOBTE: The duration of the very short flashes of light obtained by discharging a condenser through a gas tube. Study of the discharge through a tube containing argon and mercury vapour. The duration of the very intense part of the flash was of the order of 10.5 second. JACQUES SOLOMON: The absorption in matter of particles of great energy. JEAN BECQUEBEL: The determination of the paramagnetic susceptibilities of crystals of the rare earths, by the measurement of the paramagnetic rotatory powers. RAYMOND RICABD and ANTOINE SAUNIEB: The spark spectra of cadmium. Results of a study of the Cd in and Cd IV spectra. PIEBBE AUGEB and ALBEBT ROSENBEBG: The analysis of the cosmic corpuscular radiation under a screen of 28 metres of soil. The results differ considerably from those obtained above the soil at various altitudes. The soft group, if it exists at this depth, cannot be more than 3 per cent, while at 3,500 metres it amounts to 40 per cent. GEOBGES CHAM-PETIEB: The hydration of chromic chloride in heavy water (deutohydrogen oxide). The hydration of chromium chloride in ordinary and heavy water has been followed by measurements of the electrical conductivity. The reaction proceeds more slowly in the heavy water, the ratio of the velocities being approximately one to three. MLLE. M. T. SALAZAB: The constitution of the capillary layer in solutions of malachite green. RENE DALMON: The nitration of cellulose by the vapour of nitrogen pentoxide. The yield of trinitrocellulose in this reaction was found to be 99.3 per cent. MABCEL BALLAY: The constitution and properties of some alloys of iron, carbon and beryllium. Study of seven alloys containing amounts of beryllium increasing up to 3-88 per cent. PIEBBE VAN RYSSELBEBGHE: Thermodynamic potentials and affinity. PAUL RENAUD and EBNEST BAUMGABDT; The law of displacement of equilibrium. ANDBE CHBETIEN and OSCAB HOFFEB: The existence of two hydrates of potassium thiocyanate. HENBI GUEBIN: The action of heat on calcium and strontium ortho-, pyro- and metarsenates. The orthoarsenates can be heated to 1,200° C. in a vacuum without change: pyroarsenates and metarsenates by prolonged heating at temperatures above 800° C. are slowly converted into orthoarsenates. XAVIEB THIESSE: The action of oxidising agents on sodium hypoferrite. A description of various products obtained by treating alkaline solutions of sodium hypoferrite with chlorine and bromine: the concentration of the sodium hydroxide is the determining factor. JEAN BABLOT: The hydrogenation of bituminous schists at the ordinary pressure. Results of the distillation of four schists of different types in hydrogen at the ordinary pressure. The yields of oil were increased, the tar and sulphur percentages reduced. MLLE. RENEE LE BLANC: Some Chcetoceros of the Etang de Thau. ANTONIN TBONCHET: Observation in vivo of the tactile dots of the tendrils of Bryonia dioica. A. QUINTANILHA: The cytology of the copulations illegitimes in Coprinus fimetarius. ANTOINE MAGNAN and HENBY GIBEBD: Study of the pressures about a pigeon beating its wings. BOBIS EPHBUSSI and GEOBGE W. BEADLE: The conditions of autodifferentiation of Mendelian characters. JEAN LAVOLLAY: The fixation and exchange of cations in living beings. The character of generality of the laws of exchange of bases. EMIL CIONGA: An acid ester contained in the root of officinal valerian. RAOUL LECOQ and RENE CABEL: Comparison of the acetone-producing action of some food lipids and castor oil.
