Abstract
PARIS Academy of Sciences, March 9 (CM., 202, 785-884). Louis LAPICQTJE: Notice on the late Ivan Petrovitch Pavlow. ALFRED LACROIX: The volcanic rocks of Pitcairn Island (Southern Pacific Ocean). JOSEPH MONTGOLFIER: An internal combustion motor. A sealed letter deposited in 1784. EDOUARD LE ROY: The formulae of Lorentz. EMILE JOUGTJET: Waves of shock and continuous waves of certain gases. RICHARD FOSSE and PAUL DE GRAEVE: The synthesis of cyanamide by the oxidation of formaldehyde and ammonia. By the oxidation of a solution of formaldehyde and ammonia with calcium permanganate, cyanamide was produced, in quantity about 2 per cent of the aldehyde oxidised. HYACINTHE VINCENT and FRANCOIS MOREL: The neutralising action in vitro of certain chemical bodies on the toxic power of curare. The substances found previously to exert a neutralising effect on certain toxins and alkaloids were found to exert a similar action on curare. CHARLES POISSON and ANDRE SAVORNIN: The magnetic anomalies at the summit of Rantoandro. Certain basalt peaks in Madagascar show intense magnetic anomalies, possibly sufficient to be dangerous to aeroplanes flying by compass. EDM. SERGENT, A. DONATIEN, L. PARROT and F. LESTOQUARD: The evolutive cycle of the sporozoan Theileria dispar, the agent of the bovine theilerosis of Mediterranean countries, in the ox and in a tick. JACQUES DE LAPPARENT was elected Correspondant for the Section of Mineralogy in succession to the late Georges Friedel. PAUL LEVY: Observations on a note of M. Denjoy. LEONIDAS KANTOROVITCH: The properties of linear semi-ordinate spaces. F. LEJA: Certain functions of ensemble in any metric space. ARMAND RAUCH: The integral algebroids of p order admitting angles of divergence 7u/p. MICHEL LUNTZ and ANDRE JAPY: The dispersion of heat by turbulent convection and the measurement of the turbulence. PAUL SCHWARZ: The permanence of alternate eddies in a rectilinear canal. JEAN DELSARTE: A problem of diffraction. ALEXANDRE MARCEL MONNIER and JOSEPH BAZIN: A generator producing sinusoidal oscillations of constant amplitude over a very extended range of frequencies. ROMOLO DEAGLIO: The thermo-electric and voltaic properties of normal and abnormal metallic films. The normal film can be distinguished by opposing it to the massive metal in a cell, when no E.M.F. should develop. It is shown that two gold conductors, one thick and the other of green film thickness, are voltaically equivalent but thermo-electrically different. G. WATAGHIN: The interaction between protons and neutrons. MAURICE ROULLEAU: The influence of temperature on the sensibility of rapid photographic emulsions. The results of experiments on a dozen different emulsions are shown graphically, with density and temperature of the plate as variables. The sensibility was reduced as the temperature was lower. RENE DE MALLEMANN, PIERRE GABIANO and F. SUHNER: A new absolute determination of the magnetic rotatory power of water. With the apparatus used the rotations observed were of the order of 55°. For the green mercury line the Verdet constant at 11.5° C. was found to be 1.543 × 10.2 ± 0.001 minutes of arc. MARCEL LECOIN: The deviation of the p-rays on nitrogen nuclei. PIERRE PREISWERK and HANS VON H ALB AN, JR.: The relative positions of the resonance levels for the capture of neutrons by silver and by iodine. MAURICE ENGELDINGER: Study of the formation, in dilute solution, of the colloidal resins obtained by the action of formaldehyde on resorcinol. CLEMENT DUVAL: Ferric oxalate. From a study of the ion transport in absolute alcoholic solution the author concludes that this substance is not ferric oxalate, Fe2(C2O4)3 + 4 H2O, but behaves as ferritetrahydrin ferrioxalate, Fe(C2O4)3.Fe(H2O)4. Liou GUI TAO and WANG SHIH Mo: The equilibria between m chloro-pentammine cobalt sulphates and their sulphuric solutions. ARMAND MARIE DE FICQUELMONT: The physicochemical study of the neutralisation of aqueous solutions of the metaphosphimic and diimidotriphosphoric acids. PIERRE DONZELOT and MAURICE CHAIX: The Raman effect in organic sulphides. JEAN ETTORI: The colour reaction of titanium with ascorbic acid and other molecules containing the group -C(OH)=C(OH). The formation of an orange yellow complex with titanium salts is a general property of the above group, named the orthodiol-ene group. RAYMOND PAUL: The synthesis of the Carlina oxide. This substance, extracted from the roots of Carlina acaulis, appears to be the only acetylene derivative occurring in Nature. A compound of the same composition has been prepared synthetically, resembling the natural product, but not quite identical, possibly on account of incomplete purification. JACQUES BOURCART: The marine Quaternary on the coast of Cap Saint-Vincent in the estuary of the Sado. ANDRE SAVORNIN: The possibilities of magnetic prospecting in Madagascar. An account of the difficulties encountered and suggestions for reducing errors. Louis EBLE: The values of the magnetic elements at the Val-Joyeux station (Seine-et-Oise) on January 1, 1936. FRANCIS ROGER SPENCER HENSON: The large Foraminifera of the Oligocene of Palestine. MLLE. FERNANDE FLOUS: The natural classification of the Pinaceae. EMILE MICHEL -DURAND: The metabolism of the phosphorus compounds of the acorn in the course of germination in the light. HENRI MARCELET: The presence of hydrocarbons in the product removed by the deodorisation of olive oil. The examination of the substances removed by treatment of olive oil with superheated steam proved the presence of seven hydrocarbons. The original olive oil contained only 0-007 per cent of these hydrocarbons. G. and M. ARNAUD: Virus diseases of the Prunus group of Rosacese. PIERRE FEYEL: The influence of the renal secretion of urea on the working of the resorption apparatus of chlorides in mice. J. LEGENDRE: The continental penetration of the maritime mosquito. The mosquito sEdes punctatus, which normally breeds in salt water pools, can penetrate several kilometres inland, depending on the distance the sea-water reaches from the coast. PAUL BONNE VILLE: The ectodermic origin of certain parts of the royal adipose tissue of termites. MME. VERA DANTCHA-KOFF: The capacity of an induced ovary of a bird to condition secondary sexual characters. GEORGES TANRET: The comparative velocities of hydrolysis of some glucosides under the influence of ultraviolet rays, acids and diastases.
