 Fevrier. — The greater portion of the Number is occupied with a 

 continuation of Bra va is' essay, sur la disposition des fenilles cur-

par M. Aug. de Saint-Hilaike. Precis des observations sur 



lafamille des Hypoxylos, par M. de A. Libert. The Number con- 

 tains besides a short notice of Esenbeck's well-known Genera Plan- 

 tarum ; and of a large systematic work on the Grasses by Kunth. 

 An error in the memoir of Jussieu is corrected. It is there stated,

 author of this, as the former had himself acknowledged. 



Mars. — The only original paper is a Memoire sur I' accroissernent

 the ancients, M. Tritonis, Linn. — Murex, — affording the dye used 

 by painters. — Ostrea edulis, — the history of this shell-fish is imper- 

 fect, the writer also considers the European oyster " smaller and 

 thinner, and more rounded than the American, while the lower valve 

 is less concave or vaulted. It is not beaked, and the fish, compared 

 with the size of the shell, is smaller, and it possesses a different 

 flavour, while their habits are so dissimilar, that there can be no 

 doubt of their being distinct species." — Ostrea scahra — My a
