[November 24, 1892 



Paris. 

 Academy of Sciences, November 14. — M. d'Abbadie 

 in the chair. — Heat of combustion of camphor, by M. Berthelot. 

 — Remarks on a note by M. A. Colson on the rotating power 

 of the diamine salts, by M. C. Friedel. — Researches on the 

 ■chemical constitution of the peptones, by M. P. Schiitzenberger. 

 — Influence of the distribution of manures in the soil upon their 

 utilization, by M. H. Schloesing. — On the laws of dilatation of 

 gases under constant pressure, by M. E. H. Amagat. Tables 

 are given of coefficients of expansion of carbon dioxide under 

 pressures ranging from 50 to 1000 atm., and temperatures up 

 to 258° ; and for oxygen, hydrogen, nitrogen and air, under 

 pressures up to 3000 atm. For CO2 the coefficient has a 

 maximum at a certain pressure for each range of temperature. 

 This maximum corresponds to a higher pressure as the tempera- 

 ture rises. For the other gases the coefficient decreases regularly 

 as the pressure increases. As regards temperature, the coeffi- 

 cient of expansion of COj for each pressure reaches a maximum 

 at a certain temperature and then decreases. This'temperature 

 is the higher, the greater the pressure. The more permanent 

 gases behave as if they had already passed their maximum. — 

 Study of the pathogenic power of fermented beet-root pulp, 

 by M. Arloing. — Observations of the new comet Holmes (/ 

 1892), made at the Paris Observatory (west equatorial), by M. 

 O. Bigourdan (see Astronomical Column). — Transformation of 

 the great telescope of the Paris Observatory for the study of 

 radial velocities of the stars, by M. H. Deslandres (see 

 Astronomical Column). — Summary of solar observations made 

 at the Royal Observatory of the Roman College during the 

 third quarter of 1892, by M. P. Tacchini. — On the inversion of 

 Abelian integrals, by M. E. Goursat. — On the summation of a 

 certain class of series, by M. d'Ocagne. — On the equations of 

 dynamics, by M. R. Liouville. — Experimental researches on 

 the deformations of metallic bridges, by M. Rabut. — Conditions 

 of equilibrium and of formation of liquid microglobules, by M. 

 C. Maliezos. The following experimental results were arrived 

 at : When a liquid spreads over the free surface of a denser 

 liquid, microglobules are produced on inverting the position of 

 the two liquids. If a liquid rests in drops on the surface of a 

 denser liquid, then in the inverse position the denser will spread 

 over the less dense liquid. — Demonstration of the existence of 

 interference of electric waves in a closed circuit, by means of 

 the telephone, by M. R. Colson. A Rhumkorff coil was kept 

 vibratincr at 130 per second by a thermopile. To one of its 

 terminals was attached a copper wire ending in a hook, to 

 which a linen thread soaked in calcium chloride was attached 

 by one end, the other hanging free. One of the terminals of a 

 telephone was placed in contact with the thread, the other 

 terminal being isolated. Under these conditions, the sound in 

 the telephone was completely extinguished at a certain distance 

 from the copper. When both the ends of the thread (which 

 was 3 m. long) were connected up by fine copper wires, two 

 points of extinction were reached, one from each end. On 

 shortening the thread these points approached each other and 

 formed a zone of extinction between them. This zone of ex- 

 tinction spread over the entire copper w ires as the thread was 

 shortened to zero. The neutral zone is due to interference of 

 two waves of the same period and of equal potential meeting 

 in opposite directions. — On the co-existence of dielectric power 

 and electrolytic conductivity, by M. E. Cohn. — Observations 

 on the preceding communication, by M. Bouty. — Magnetic 

 properties of bodies at different temperatures, by M. P. Curie. 

 These were measured by bringing samples of the bodies between 

 the ends of two electromagnets inclined to one another, and 

 measuring the forces experienced by means of a torsion balance. 

 The bodies were heated in a porcelain crucible, the heat being 

 supplied by platinum wires carrying a current, and measured 

 by a Chatelier thermocouple. — On the propagation of vibrations 

 through absorptive isotropic media, by M. Marcel Brillouin. — 

 On a new relation between variations of luminous intensity and 

 the numerical order of the sensations, determined by means of 

 a luminous paint, by M. Charles Henry. — Essay of a general 

 method of chemical synthesis : experiments, by M. Raoul 

 Pictet. — On the fusion of carbonate of lime, by M. H. Ee 

 ■Chatelier. — On the molecular weights of sodammonium and 

 potassammonium, by M. A. Joannis. — On some crystallized 

 sodium tilanates, by M. H. Cormimboeuf. — On a propylamido- 

 phenol derived from camphor, by M. P. Cazeneuve. — On the 

 colouring matter of the pollen, by MM. G. Bertrand and G. 



Poirault. — On the manufacture of melanite garnet and sphene, 

 by M. L. Michel. — On the rotating power of solutions, by M. 

 Wyrouboff. — Researches on the mode of elimination of carbonic 

 oxide, by M. L. de Saint-Martin. — Vital fermentations and 

 chemical fermentations, MM. Maurice Arthus and Adolphe 

 Huber. — Remarks on th^ preceding communication, by M. A. 

 Gautier. — Influence of the transfusion of blood from dogs vac- 

 cinated against tuberculosis upon tuberculous infection, by MM, 

 J. Hericourt and Ch. Richet. — On a new species of chromo- 

 genic bacteria, the Spirillum luteum, by M. Henri Jumelle. — 

 On two parasitic myzostomes of the Antedon phalangiiim 

 (Miiller), by M. Henri Prouho.
