 members were elected, and eighty-nine donations received. 

 The follow ing papers were read : — Notes on the genus Macro- 

 zamia, with descriptions of some new species, by C. Moore, 

 F.L.S.— A list of double stars, by II. C.Russell, B.A., F.R.A.S.

 of an extinct Chelonian reptile {Notochclys costata, Owen) from 

 the Flinders River, Queensland, being the first Chelonian found 

 in Australia. 



Paris 

 Academy of Sciences, October 22. — M. Blanchard, presi- 

 dent, in the cliair. — River navigation ; endless chain towing, 

 by M. Dupuy de Lome. The author describes the recent ex- 

 p2riment made on the Rhone of a new system of towage, wliich 

 appears satisfactorily to solve the problem of the economic trans- 

 port of goods on this most difficult of navigable rivers, and, a 

 /orliori, on all streams with a moderate current. The success of 

 the experiments is due to the employment of two endless lateral 

 chains, worked with independent machinery by a single hand, 

 and serving at the same time to steer the vessel. — Note on a 

 formula of Hansen applicable to the celestial mechanism (con- 

 tinued), by M. F. Tisserand. — Disinfection of ornamental plants 

 intended for exportation, by M. Laugier. The successful ex- 

 periments m.ade in concert with Dr. Krenig of Asti at the 

 Agronomic Station of Nice in December, 1S82, were renewed 

 during the month of September last with most satisfactory re- 

 sults. — Note on some arithmetical theorems, by M. Stieltjes. — 

 On surfaces whose curve is constant, by M. G. Darboux. — On 

 the law regulating the distribution of tension in an elastic plate 

 of arbitrary primitive form encircling a cylinder of any right sec- 

 tion, in cases where the friction is uniform, by M. H. Leaute. — 

 On the movement of a rolling weight along an elastic horizontal 

 rod fixed at both ends in cases where tlie mass of the rod is 

 much smaller than that of the weight, by M. J. Boussinesq. A 

 wider application is here shown of the problem of rolling masses | 



solved by Willis and Stokes, as described in the paper inserted 

 by Stokes in the Cambridge Phil. Trans., vol. viii. 1^49. — Ob- 

 servations on a reply of M. Faye touching diverse phenomena of 

 solar spectroscopy (Comptcs Ki'ndtis, October 8, p. 779), by M. 

 L. Thollou. — On the inductive force due to the variation of 

 intensity in the electric current of a flat spiral multiplication, 

 and, on the comparison of this force with that exercised at great 

 distances by a spherical solenoid or a solenoidal fictitious sun, by 

 M. Quet. — -Note on the determination of the equivalents of 

 copper and zinc by means of their sulphates, by M. H. Bau- 

 l)igny. — On the transformation of hydrocarburets into correspond- 

 ing aldehydes by means of chlorochromic acid, by M. A. Etard. 

 — Note on the state of the sensitive nerves dnring the excitement 

 produced by strychnine, by M. Couty. — On two cases of peri- 

 pheric nervo tabes (ataxy of the lower members, combined 

 with absolute integrity of the posterior roots, of the spinal 

 ganglia and spinal marrow), by M. J. Dejerine. — On the 

 secreting epithelium of the kidney of 13atrachiaus (triton and 

 axolotl), by M. J. Bouillot. — On the extent and age of 

 the dioritic formations of Cors'ca, by M. Dieulafait. In-tead 

 of occupying a deep continuous vertical range, as hitherto sup- 

 posed, the author shows that the Corsican diorites belong to 

 three distinct systems — granites at .San Luccia di ToUano and 

 Ajaccio, ophiolithic or serpentine rocks of the Triassic and 

 Permian formations at Bastia and elsewhere. With these last 

 are exclusively associated the numerous sulphuretted metalliferous 

 ores occurring in the island. — A discussion of the causes to 

 which is due the movement of glaciers, by Mr. Walter R. 

 Browne. This movement is here attributed rather to atmo- 

 spheric causes (pressure and temperature) tlian to gravitation. — 

 Observations on an earthquake felt at Ghadames (Algeria) 

 towards the end of last August, by M. Duveyrier.
