Abstract
PARIS Academy of Sciences, July 31 (CM., 177, 365-432). The president announced the death of Edouard Qu©nu, member for the Section of Medicine and Surgery. A. LACROIX: A stony meteorite which fell in Morocco on August 22, 1932. R. FOSSE, P. DE GRAEVE and P. E. THOMAS: The transformation of the intermediate term of the permanganate oxidation of uric acid into allantoic acid, in the presence of the soya ferments and of potassium cyanide. CHARLES NICOLLE and L. BALOZET: Man is insensible to inoculation of the aphthous virus of known types, even in the form of a latent infection. CHARLES NICOLLE, J. LAIGRET and P. GIROUD: The transmission of typhus by bites and by ingestion of infected fleas. The ape can be infected by flea bites, rats by ingestion of infected fleas. The infections produced were of the latent type, none of the animals showing febrile symptoms. B. CABRERA and H. FAHLENBRACH: Diamagnetism and temperature. PAUL PASCAL and BONNMEMAN: The reversible passage of the dimetaphosphates to the condensed salts of Graham. Study of the metaphosphates produced by the dehydration of silver acid pyrophosphate and by heating silver hypophosphate at varying temperatures. G. B. GOUREWITCH: The canonical forms of a trivector in space of six dimensions. RENE DE POSSEL: The theory of measurement. The prolongation of an additive function of ensemble. TULLIO VIOLA: The points of convergence of general trigonometrical series. B. RIABOUCHINSKY: Total dissemination. P. DUMANOIS: Concerning the influence of the temperature on detonation in internal combustion motors. From the peroxide theory of detonation, the author concludes that if the temperature of the explosive mixture going into the motor cylinder be raised, the detonation should disappear. Experiments confirming this are described. J. LE ROUX: A new form of the Lorentz formul. J. SAVARD: The ionisation potential and formation of the molecule of hydrogen. ALEXIS GUERBILSKY: Piezo-electric crystal dynamometers in resonance vibration. J. SOLOMON: The effect of internal conversion. A discussion of the application of Dirac's theory of the electron to the explanation of the effect of internal conversion, that is, the absorption by an electron of a radioactive atom of the photon emitted by the nucleus. W. GENTNER: The absorption of very penetrating Î-rays. MARCEL LECOIN: The -radiation of radium E and of the active deposit of actinium. AUGUSTE LE THOMAS: The anomalies of the tempering of cast irons: their relation with the oxidation in the liquid state. ED. CHAUVENET and MLLE. J. BOULANGER: The compounds of zirconyl bromide with the alkaline bromides. Application of the calorimetric method indicated the formation of definite compounds of zirconyl bromide with the bromides of sodium, potassium, rubidium, csium and ammonium, but not with lithium bromide. The compound with csium bromide was isolated in crystals. O. MILLER and L. PIAUX: The Raman spectra of the cis-trans isomeric orthodimethylcyclohexanes. VOLMAR and BETZ: The emetics derived from mandelic and malic acids. The preparation and properties of sodium antimoniomandelate and sodium antimoniomalate are described. E. VELLINGER and G. RADULESCO: The antioxidising or antioxygen constituents of petrol prepared by cracking. It is suggested that the petrol passing below 170° C. should be refined and then mixed with the crude unrefined fraction passing between 170° C. and 180° C. MME. GUAISNET-PILAUD: The crystallographic constants of the hydrates of the phenyl-methylethyl betaines and of the phenylmethylpropylbetaines. J. GUBLER: The presence of the Trias at Cambogia. A. DUPRIER and G. COLLADO: The fluctuations of the terrestrial electric field. Experiments made at Paris and Madrid show that the continuous fluctuations of the electric field cannot be regarded as being due to local irregular disturbances. H. COLIN and J. AUGIER: Floridoside, trehalose and glycogen in red fresh-water Alg (Lemanea, Sacheria). J. ANDR THOMAS: The evolution of prolonged cultures of the wall of the umbilical vesicle, in the embryo of the chick. A. POLICARD: The study by micro-incineration of the distribution of fixed mineral matter in the spermatozoids of mammals. In the spermatozoids of both man and rat the method of micro-incineration shows at the level of the head the presence of a part poor in mineral matter and a posterior part containing much more. SWIGEL and THODORE POSTERNAK: The phosphorus containing nucleus of the ichtulin of the pike. MME. ANDRE ROCHE: The comparative study of the chemical constitution of normal animal muscle, dead through total starvation or through protein starvation.
