 sented minerals and fossils, as follows — cubic pyrites, forest marble, 

 quartz crystals, two specimens of fossil fishes from Mount Hebron, 

 fossil Ostrea from Florida, four specimens of polished madreporites. 

 Mr. Glover presented a specimen of reddish clay, raised in the Chinese 

 Sea upon the flukes of an anchor. Dr. David Hosack presented a 

 bust of Sir James Edward Smith. Mr. H. R. Schoolcraft presented, 

 through Dr. Dekay, a box of fossils from Lake Huron and the sur- 

 rounding country. Mr. Cooper exhibited, from Baron Lederer, a 

 number of a work recently published, on the animals of Brazil, en- 

 titled "Collectanea ad Faunam Brasiliae, von Karl Von Schreibers, 

 Vienna, 1833," which work he was desired to exchange for others 

 on natural history. Dr. John Backman, of Charleston, S. C, was 

 elected a corresponding member. James McGillivray, Esq. of Ed- 

 inburgh, was elected a corresponding member. 



May 19. — Dr. Swift in the chair. — Visitor, Mr. Whelpley of 

 Cleaveland, Ohio. Dr. S. L. Metcalf delivered some remarks on the 

 phenomena of the galvanic pile, and declared his opinion, that the 

 results perceived on varying the number of plates, proved beyond 

 doubt the identity of caloric and latent electricity. As the size of 

 the plates were diminished and the number increased, the imponder- 

 able fluid evolved presented less and less the properties of caloric, 

 and more and mote those of electricity. By immersing the plates 

 in the acid solution, the oxygen of the acid and the metal, give out 

 their caloric in the process of oxidation. Dr. Boyd presented a spe- 

 cimen of Orthoceratite from Newburg, N. Y.
