and mixtures of neutral sulphates of zinc and copper with sulphate 

 of hydrogen. — M. Elie de IJeaumont made some remarks upon 

 the Mont Cenis tunnel, and read a letter from Fatjier Secchi on 

 the pendulum experiments which it is pro]iosed to make in the 

 tannel. — M. J. Bourget presented n paper on the velocity of sound 

 in sonorous tubes. -M. Jamin communicated a note by M. E. 

 Gripon on the transverse vibrations of wires and thin plates, and 

 also a note by M. Alvergniat on a new phenomenon of phospho- 

 rescence produced by frictional electricity. According to the 

 latter a small quan'ity of chloride or bromide of silicium 

 hermetically sealed in a vacuum tube givt-s a bright luminosity 

 when the tube is rubbed with a piece of silk. The cliloride 

 gives a rose colour, the bromide a greenish yellow. — M. Le 

 Verrier presented a note on the history of the observations on 

 the action of ecliptic conjunctions upon the elements of terrestrial 

 magnetism, by M. Moise Lion. — M. Le Verrier also pre5ented 

 a note by M. Tarry, giving an account of an aurora borealis ob- 

 served at Brest on the 9th November, in which the author 

 noticed particularly the perturliations manifested l)y the appara- 

 tus employed in telegraphy. — M. Le Verrier also remarked that 

 auroras had been observed in Piedmont on the nights of the 

 2nd, 9th, loth, and 15th November, and referred to the coin- 

 cidence between the occurrence of these phenomena and the 

 November flight of meteors, which M. C. S.ainte-Claire Deville 

 supposed to exist. — M. Berthelot read the conclusion of hisp.aper 

 on the formation of precipitates. In this he discussed the changes 

 which take place in the state of aggregation of precipitates, 

 illus'rating his views by the facts observed in the cases of the car- 

 bonates of strontia, baryta , lead, and silver, and of the oxa- 

 lates. — M. Wurtz presented a note by M. E. Ritter on the trans- 

 formation of albuminoid matters into urea by permanganate 

 of potash. This note contained air experimental confirmation of 

 M. Bechamp's statement. — M. de Quatrefages communicated an 

 extract from a letter by M. E. S. Delidon, on the butts of Saint- 

 Michel-en-rHerm, and on the means by which their elevation 

 above the sea, and other local elevations, may have been 

 effected. He considers that local elevations may be due to infil- 

 tration of fresh and salt water. — Mr. E. Blanchard presented a 

 note by JL S. Jouidain on the anatomy of the sunfish (Ortlnv^c- 

 risciis iiio/a) —An extract of a letter from M. A. Poey to M. Elie 

 de Beaumont, on the influence of violet light upon the growth 

 of the vine, pigs, and cattle, was read. — M. de Qiratrefages pre- 

 sented a note by M F. Garrigou on lacustrine habitations in the 

 Pyrenean region of the South of France. In this note the author 

 describes the results obtained by him in the investigation of the 

 deposits of ancient lakes at the foot of the Pyrenees.
