Botany. — M. A. Steinheil (the late) on opposite leaves which 

 become alternate by union. — Arendt on the capillary action of hairs 

 (from the ' Flora '). — M. Desmazieres on Cryptogamia new to 

 France. — M. Tulasne on French Ly coper dacece. 



July. — Zoology. — I\I. Serres on the human allantoic!. — M. d'Or- 

 bigny on the Gasteropoda of the Cretaceous system. Of 325 spe- 

 cies found in the cretaceous strata of France, 250 are new. Out 

 of the total, 81 species belong to the Neocomian (the lowest portion 

 of the Lower Greensand) and 9 to the " Aptien," which two divi- 

 sions form together the " Etage Neocomien" of D'Orbigny, a name 

 equivalent to the Lower Greensand of Dr. Fitton. To the "Albien," 

 I. e. the Gault, belong 77 species; to the " Turonien," i. e. Upper 

 Greensand, 134; and to the " Senonien," i.e. white chalk, 24. Each 

 geological group is marked by an assemblage of peculiar species. 

 The new names given by AL d'Orbigny to the groups will appear to 

 most geologists useless and inconvenient : it is a relic of an old, but 

 very bad habit of French naturalists. — Experimental researches on 

 Inanition, by Dr. Chossat. 



Botany. — JM. Mirbel on the anatomy of the Date-Palm. — AL Gau- 

 dichaud's reply to M. Mirbel. — M. A. Meyer on the Daphnacece

 soonii of Brandt. With plates. 



Botany. — Note on the distinctive characters which separate vege- 

 tables from animals, and on mineral secretions in plants, by M. Payen. 

 The author, by chemical analysis, comes to the same conclusions which 

 M. Decaisne arrived at by organographical research, viz. that Corul- 

 lina officinalis, Halimeda, Opuntia and their alUes are vegetables and 

 true Algae. — Dr. Montague on the tribe of Podaxinece, and on Gyro- 

 phragmium, a new genus of that tribe. — Conspectus generis Gaillo-
