  • Description: PARIS. Academy of Sciences, October 4.-M. Ed. Perrier in the chair.-J. Boussinesq: The correct calculation of the influence of climatic inequality on the velocity of increase of terrestrial temperatures with depth from the surface.-H. Douville: The orbitoids of the peninsula of California. A study of material arising from the geological explorations of Arnold Heim. Some specimens belong to the genus Orthophragmina, and it is the first time these have been discovered in this region. Some rare Foraminifera include specimens of Amphistegina Niasi.-E. E. Barnard: Some supposed movements in stars near the cluster Messier 11 = N.G.C. 6705. The observation of J. Comas Sola on movements of stars in the neighbourhood of this cluster do not appear to be well founded. They were based on the stereoscopic examination of photographs taken at an interval of three years. The author has examined photographs of the same region separated by an interval of twenity-two years, making use of a Zeiss stereo-comparator, but no movement of the stars in question can be observed.-J. Comas Sold: The approximate positions of a small planet, apparently new,-C. Camichel: Hammering in water pipes entirely free from air. Experimental determinations of the velocity of wave transmission in an 80 mm. iron pipe, 154 metres long, and of the pressures produced by sudden closing of a tap in the main.-Alb. Colson: The heat disengaged by a solid body passing to the state of saturated or dilute solutions. Details of experimental studies by a new method on the heats of solution of common salt.-B. Bogitch: The reciprocal solubility of copper and lead. Copper and lead form a double layer when the amount of copper exceeds 34-5 per cent., and is below 87 per cent. This double layer can only exist between the temperature of solidification of the upper layer (9400 C.) and 9750 C.- Arnold Heim: The geology of the southern part of lower California.-MM. Debierne and Regaud: The use of the condensed radium emanation in closed tubes in the place of radium compounds, and the estimation (in millicuries of emanation destroyed) of the energy used up in radio-active applications in general. An account of the advantages, from the points of view of economy and ease of application, of condensed radium emanation for biological purposes.
