Academy of Sciences, March 11 (C.B., 200, 869-992). LUCIEN CAYEUX: The conglomerate structure in lacustral medium in the old sedimentary series of France. RICHARD FOSSE, PAUL DE GRAEVE and PAUL EMILE THOMAS: The identification of small quantities of amino acids by elementary analysis. The method is based on the conversion of the amino-acid into a hydantoic acid with potassium cyanate and condensation of this with xanthydrol. CHAULES NICOLLE and MME HELENE SPARROW: The weak pathogenic power, for small apes, of the murin virus I from rats at the port of Tunis. J. CABANNES and J. DUFAY: The annual variation of the intensity of the bright lines of the night sky. The results suggest that the polar aurora and the emission of the nocturnal sky may have a common cause. HENRI LAGATU and Louis MAUME: The kinematics of lime and magnesia and their physiological relation in the tobacco leaf. Method of leaf relays. SYLVAIN WACHS: The reduced form of a quaternion unilateral linear substitution. N. AKHYESER and M. KREIN: A quadrature formula of Tchebicheff. ROBERT MEY-NIEUX: The functional equations expressing the theorems of addition and of others more general. ALEXANDRE DUTOUR: The possibility of deciding experimentally the difference between classical kinematics and relativist kinematics. Z. HORAK: The effect of the friction of pivoting on the shock of elastic bodies. SIMON DE BACKER: Viscous fluids and waves capable of propagation. ANTOINE BRUN: The variable stars of the great nebula of Orion. A list of ten new variable stars. VICTOR NAGGIAR: The production of threads and vortices in nematic liquids. JACQUES SOLOMON: The applicability of the principle of conservation of the moment of quantity of motion to nuclear processes. N. THON: The constitution of the double layer and the trend of the curve of potential in the electrolytic neutralisation of metallic ions. G. WATAGHIN: The thermal equilibrium of elementary corpuscles. LEON ENDERLIN: Study of the magnetic susceptibility of tetraphenylrubene and its dissociable oxide. The magnetic measurements agree with thermochemical data and tend to establish that the oxygen of the dissociable rubene oxide is connected with the organic substratum by normal valencies. This is a new argument in favour of the formula adopted for oxyrubene. C. H. CARTWRIGHT and J. ERRERA: The intramolecular isomerism of ot-picoline studied in the extreme infra-red. The hypothesis of the existence of the second tautomeric form of a-picoline is not confirmed by these researches. ANDRE CHABRIOU and MLLE. SUZANNE VALETTE: The influence of alkaline iodides on the properties of photographic emulsions. RENE AUDU-BBRT: The sensibility of photon counters. JEAN ROULLEAU: The mechanisms of the photopotential of sheets of oxidised copper. LEONARD SOSNOWSKI: The artificial radioactivity of iridium. The iridium was produced by the action of neutrons from beryllium irradiated with radium. The artificial radioactivity thus induced is fairly intense. The results are not in agreement with those of Fermi. HENRI MURAOUH and ANDRE MICHEL-LEVY: The origin of the luminosities which accompany the detonation of explosives. E. DUCHEMIN: The influence of light on periodic precipitations in gelatinous media. The precipitation of silver chromate, phosphate and
