some formate is also produced.—A general method for the 
preparation of anhydrous chlorides: C. Matignon and F. 
Bourion. A mixture of chlorine and sulphur chloride re- 
acts with metallic oxides at moderately low temperatures, 
giving an anhydrous chloride. Details are given of the 
preparation of the chlorides of silicon, aluminium, thorium, 
praseodidymium, neodidymium and samarium.—On_ the 
phenylurethanes of the sugars: L. Maquenne and W. 
Goodwin.—On allyl- and propenyl-alkyl ketones: E. E. 
Blaise. In the allyl-alkyl-ketones, migration of 
ethylene linkage occurs with extreme facility, and details 
are given of the various ways in which this may be effected. 
—The combination of saccharose with some metallic salts : 
D. Gauthier.—On the development of annual oil-contain- 
ing plants: G. André.—On the development of the peri- 
thecium in the Ascomycetes: P. A. Dangeard.—On the 
perpetuation of the mildew of the vine: Gy de Istvanf. 
The author has been able to prove the presence of the 
mycelium in a latent state in several organs of the vine | 
during the winter months.—Faults and folds: H. Douvillé. 
—On the chemical composition of the crystalline strata of 
the Belledonne Chain: Pierre Termier and André 
Leclére.—The action of the n-rays upon the sense of hear- 
ing: Augustin Charpentier. The sensibility of the ear is 
increased when acted upon by the n-rays.—The physio- 
logical action of the m,-rays of Blondlot: Augustin 
Charpentier. M. Blondlot has recently described a new 
species of rays possessing physical properties which are the 
inverse of the n-rays previously studied. These rays also 
produce the inverse effects on the nervous system; thus 
they diminish the intensity of the sensation of smell, whereas | 
the n-rays increase it.—On the relations of the colouring 
matter of subrenal extract with tyrosine: Gab. Bertrand. 
—The oxidation of formic acid by extracts of animal tissues 
in presence of hydrogen peroxide: F. BattelliimThe action 
of artificial oxydases upon the tetanic toxin: Aug. Lumiere,
