chloride giving hydroxylamine chloride has been applied by the 

 author to the quantitative determination of nitrates in potable 

 waters. — The action of various alcohols upon some acetals of 

 monovalent alcohols, by M. Marcel Delepine. — On 

 three new alkaloids from tobacco, by MM. Ame Pictet and 

 A. Rotschy. Further particulars of the physical and chemical 

 properties of the three alkaloids nicoteine, nicotimine and 

 nicotelline. — The action of phenylhydrazine and of hydrazine 

 upon the two isomeric methyl butyrylacetylacetates, by M. 

 Bongert. On paraoxyhydratropic acid, by M. J. Bougault. — ■ 

 Some new reactions of organometallic derivatives, by M. E. E. 

 Blaise. — On a new base derived from glucose, by MM. L. 

 Maquenne and E. Roux. The base, which is termed glucamine, 

 is obtained by reducing glucosoxime with sodium amalgam. — 

 Action of the alkylcyanacetic esters on the diazochlorides, by 

 M. G. Favrel. — Reduction of the nitro-derivatives of the azoic 

 colouring matters, by M. A. Rosenstiehl. — On two new 

 acetylenic acids. Synthesis of caprylic and pelargonic acids, 

 by MM. Ch. Moureu and R. Delange. — On the indoxylic 

 origin of certain red colouring matters of urine, by M. L. 

 Maillard. — The calculation of the results of milk analyses, by 

 MM. Louise and Riquier. — Segmentation in the genus Trochus, 

 by M, A. Robert. — Action of isotonic solutions ol chlorides 

 and of sugar on the eggs of liana fusca, by Mme. Ronfeau- 

 Luzeau. — The stimulation of nerve and muscle by waves of very 

 short duration, by M. G. Weiss. — Action of alcohol upon the 

 gastric secretion, by MM. Albert Frouin and M. Molinier. The 

 increased secretion of the gastric juice caused by alcohol is 

 shown experimentally not to be due, as has been usually supposed, 

 to a direct local action, nor is it due to an effect produced upon 

 the nerves of taste. — On the second fermentation of the wines of 

 Champagne, by M. E. Manceau. — Apparatus for the exact 

 measurement of the skeleton and of other organs giving a clear 

 image in radiography, by M. G. Contremoulins. — On the origin 

 and mode of formation of the Oolitic iron ore of Lorraine, by
