mannite, by A. Sivoloboff and A. Alekhin. — On the structure 

 of the atmosphere and on the general laws of gases (second 

 paper), by E. Rogovsky. The criticism of the author brings him 

 to the conclusion that the kinetic theory of gases must be revised 

 before deducing the hypsometrical formula. The inquiry is to 

 be continued. — On the magnetism of iron wires which are 

 partially inclosed by a magnetising bobbin, by P. Bakhmetieff. 

 The curve which expresses the relations between the magnetic 

 momentum (in) and that part of the wire (/) which is directly 

 submitted to the action of the bobbin has an irregular shape ; 

 the fraction m : I reaches a maximum, which is reached sooner 

 when the magnetising force is greater. —On the specific heat of 

 liquids, by A. Nadejdin. — On the theory of dimensions, by N. 

 Sloughinoff. — On a general law of dilatation of liquids, by M. 

 Avenarius. — Remarks on M. Bardsky's paper on the intramole- 

 cular force. 



Vol. xvi. fasc. 5. — On alizarine oils, by P. Loukianoft". They 

 are found to consist chiefly of basic salts of common fatty and 

 sulpho-fatty acids, the former in greater amount. — On the de- 

 pendency of photo-chemical phenomena upon the amplitude of 

 the luminous wave, by C. Timiriazeff. On the ground of several 

 observations the author concludes that it is probable that the 

 more energetic reactions are due to waves having a greater am- 

 plitude ; and that, out of the waves absorbed by a body, those 

 having a greater amplitude act more energetically. — Action of 

 ethylic iodide on the azobenzoate of silver, by P. Goloubeff. — 

 On naphtochinone and its derivatives, by O. Miller. — On the 

 separation of calcium from strontium by Snidersky's method, 

 by J. Bogomoletz. — On triphenylamidomethan, by W. Hemilian 

 and G. Silberstein. — On some salts of mesotartaric acid, by 

 S. Przibytek. — On the heat of magnetisation of a circular mag- 

 net, by P. Bakhmetieff. It is much less than in rectilinear 

 magnets, and seems to follow other laws ; the development of 

 heat is altogether doubtful in such magnets. — The steam-engine 

 made by Polzounoff in Siberia in 1763, by W. Lermontoff. — 

 Notes on elementary optics. — Note on M. Kraaevitch's paper on 

 a hydrodynamic equation, by N. Petroff. — On the dilatation of 

 liquids and its relation to their absolute boiling-points ; an answer 

 to M. Avenarius, by D. Mendeleeff, being a few remarks on the 

 history of the subject and on M. Avenarius's logarithmic formula 

 of dilatatiin.

SOCIETIES AND ACADEMIES 

 Paris 

 Academy of Sciences, August 4. — M. Rolland, President, 

 in the chair. — Reply to two notes of M. Wroblewski on the 

 subject of the liquefaction of hydrogen and other gases, by M. 

 L. Cailletet. — On the influence of temperature on the property 

 of absorbing and losing moisture, possessed by vegetable earth 

 and other substances exposed to contact with the atmosphere, by 

 M. Th. Schlcering. — On the change in the excentricities of the 

 planetary orbits due to the concentration of matter in space, by 

 M.Hugo Glyden. — Report of Messrs. Gosselin, Vulpian, Marey, 

 Bert, 'Pasteur, Richet, Bouley,and Charcot on various communica- 

 tions received by the Academy on the subject of cholera. An 

 examination of forty-three letters, notes, and memoirs has led to 

 no results calling for special consideration. The chief remedies 

 proposed are hypodermic injections of chloride of pilocarpine, 

 the internal application of sulphate of quinine, of oxygenated 

 water, sulphuric lemonade, &c. More important are the views of 

 Dr. Duboue of Pan, who recommends as a preventative the 

 strengthening of the endothelial and epithelial systems by the 

 daily administration of two doses of C25 grain of pure tannin 

 prepared with ether. His curative method consists in restoring the 

 circulation by copious intravenous injections of an artificial serum 

 to which should be added one grain per litre of pure tannin. —
