fatty amines upon the dibenzoate of ethylene, by M. Marcel 

 Deseudc. — The action of halogen esters upon ammonim thio- 

 sulphocarbamate, by M. Marcel Delepine. — On the ichthyological 

 fauna of the fresh waters of Borneo, by M. Leon Vaillant. — On the 

 fishes of the Chondrostome group in the fresh waters of France, 

 by M. Louis Roule. — The morphological and anatomical variations 

 presented by the gizzard in some Coleoptera, by M. L. Bordas. — 

 On the polychoetal annelids in fresh water, by M. Ch. Gravier. 

 Excretion in the Cirripedes, by M. L. Bruntz. — The application 

 of a character of ethological order to the natural classification, 

 by M. L. Matruchot. — The distribution of sph?erulins in vegetable 

 families, by M. Louis Petit. — The present state of the volcano 

 of Martinique, by M. Lacroix. — On the evolution of the 

 spermatid in the Not onecta glauca, by MM. J. Pantel and R. de 

 Sincty. — On the presence of paranucleolar acid corpuscles in the 

 cells of Locus niger and Louts coerulens, by M. G. Marinesco. — 

 The ratio of the weight of the liver to the total weight of the 

 animal, by M. E. Maurel. Adult animals have less liver per 

 kilogram weight than young animals of the same species. In 

 the same species of animal, when differences of volume corre- 

 spond to different varieties, as in the dog, the quantity of liver 

 per kilogram of animal is higher as the animal is smaller. This 

 proportion also varies with the nature of the food. — On the 

 variations of phosphorus in animal tissue, by M. A. L. Percival. 

 — Physiological researches on the effects of cervical sympathi- 

 cectomy, by MM. Moussu and Charrin. — Muscular hfemoglo- 

 binuria, by MM. Jean Camus and P. Pagniez. — On the formation 

 of the anticorps in the serum of vaccinated animals, by MM. A.
