Abstract
PARIS Academy of Sciences, November 13 (CM., 197, 1073-1160). E. GOTJBSAT: A problem of the theory of congruences of straight lines. L. CAYEUX: The submarine alteration of the phosphatic nodules of the Albian of the Paris basin. A. BIGOT and RAOTJL FOBTIN: The boring at Incarville, near Louviers (Eure). A summary of the geological results obtained by a trial boring for petroleum. E. J. GUMBEL: The limiting distribution of the smallest value amongst the greatest. PAUL DIENES: The deformation of spaces with general linear connexion. ABNATTD DENJOY: Integration along rectifiable cyclic con-tinua. C. KTJBATOWSKI: The prolongation of homeomorphy. ANDBE CHABBUEAU: Remarks on certain movements of a viscous fluid mass, isotropic and heterogeneous. P. DUMANOIS: Concerning detonation in internal combustion motors. Reply to some criticisms by Dufraisse and Chaux. MLLE. F. BLOCH, J. ELLSWOBTH and S. P. LIAU: Photometric observations of the star ES Ophiuchi. Results of visual and photographic determinations are given. The oscillations found are characteristic of the light curves of novse. CH. BEBTAUD: The correlation between the velocity of ensemble of the A stars and their distance to the galactic plane, and on the rotation of the galaxy. FBANCIS PEBBIN: The possibility of the materialisation by interaction of a photon and an electron. TH. V. IONESCU: The working of a Crookes radiometer in the high-frequency discharge. The Crookes radiometer is as sensitive to electric waves as to light waves. This has been applied to the study of the energy consumed in an ionised gas. JEAN GENABD: The magnetic extinction of the fluorescence of iodine vapour. Photometric measurements in magnetic fields varying from 0 to 42,600 gauss gave a curve in good agreement with the theoretical formula of Van Vleck. ALBEBT TUBPAIN: Remarks on the discovery of the molecular diffusion of light by pure liquids. Historical. Directing attention to the early work of A. Lallemand in this field. He established a reflection by the molecules of a pure liquid and predicted a part of the Raman effect. GEOBGES ZIELINSKI: The polarisation of the fluorescence bands of mercury vapour. W. GENTNEB: The absorption of the penetrating y-rays. Criticism of recent work by C. Y. Chao. GEOBGES I. COSTEANTJ: Batteries with liquid ammonia and with ammoniacal solutions. Studies of the effect produced by the gradual addition of water on the E.M.F. of batteries made up with dry liquid ammonia. The changes in E.M.F. are small. N. THON: The electrolysis of solutions of metallic salts with a cathode of rarefied gas. Discharge through a gaseous cathode does not lead to a deposit of metal except in the case of the three metals silver, platinum and gold. R. ETIENNE: The displacement of equilibrium. H. MUBAOUB and G. AUNIS: Verification of the law of combustion of colloidal (explosive) powders. E. DABMOIS: The Lambert-Beer law and the nature of absorbing particles in solution. JEAN SAVABD: The ionisation potentials and energies of formation of non-polar molecules. ANTONIO DE PEBEIBA FOBJAZ: Modifications of chemical reactions under the influence of oscillating circuits. E. ELCHABDUS and P. LAFFITTE: The constitution of the magnesium-zinc-silicon alloys rich in magnesium. CHABLES DUFBAISSE and PAUL CHOVIN: Research on substances related to the rubenes. MLLE. DENISB SONTAG: Primary (3-naphthyl ethyl alcohol and p-vinylnaphthalene. H. UNGEMACH: Some new minerals. E. CHAPTJT: The anthracolithic in Central Anatolia. P. DELEAU: The presence of the lower Cretaceous at Djebel Sana, province of Constantine. MAURICE BLTJMENTHAL: The tectonic relations between the betic, penibetic and subbetic zones of the south-west of Andalusia. R. DELABY, R. CHARONNAT and M. JANOT: New researches on the radioactivity of the waters of the Ballon d'Alsace massif. P. IDRAC: Records of long duration by photography of phosphorescent materials. To do away with the friction of the writing point in a recording instrument, the author suggests the use of a fragment of phosphorescent material, with a lens focusing the phosphorescent light on to photographic paper. JEAN CHEVRIER: Observations of the atmospheric electric field at the Observatory of Ksara (Liban) during the eclipse of the sun of August 21, 1933. GEORGES DUBOIS and MME. CAMILLE DTJBOIS: The submerged forest of Leon since the middle Flandrian and the genesis of some peat bogs in this district. The results of pollen analysis have given a fairly complete history of these peat bogs, which are exposed at low tide, from the Neolithic to the present time. ANDRE DAUPHINE: Intercellular punctuations. J. CHAZE: A new example of exudation and of volatilisation of alkaloids in plants. In previous papers it has been shown that in tobacco plants under certain conditions the alkaloids can be exuded and volatilised into the air. Hemlock plants have now been examined and have been found to exhibit the same phenomena as regards the conine. DE CONDE and HETJDEBERT: Contribution to the study of the baking value of bread. M. RATJCOURT and B. TROUVELOT: Researches on the constituents of the leaves of Solanum tuberosum determining the feeding of the larvae of Leptinotarsa decemlineata. The leaf principles attracting the beetle are localised almost exclusively in the green part. They are soluble in certain organic solvents, and are not volatile or destroyed by dry heat. RAOUL LECOQ: The role of the D vitamins in the utilisation of glycides by the organism of the pigeon. The comparative influence of some hexoses and of some disaccharides (holosides) incorporated in diets containing 66 per cent of glycosides. THEODORE POSTERNAK: The phosphorus of the fecula of potatoes. G. MOURIQUAND and M. BERNHEIM: Dietotoxics and protection of the liver by food equilibrium.
