received a case of minerals sent by the Mayor of Nantes to the 

 Society, to be exchanged for American minerals ; he also had 

 a copy of Catesby's Natural History of South Carolina for the 

 Society. About to return to France in a few weeks, he requested 

 the Society to communicate to him a series of instructions 

 relative to its wants, which he would use all his influence to 

 answer. 



The letter, containing suggestions of great importance, was 

 referred to the Curators. 



Prof. Wyman, in alluding to the remarks of Mr. Alger 

 at the last meeting on the carnivorous propensities of bull- 

 frogs, said, that on dissection of a large bull-frog he had 

 found a mouse in its stomach. 



He had seen one devour a large spider which had been for a 

 longtime preserved in alcohol, an Ascaris lumhricoides from the 

 human body, &c. showing that they are not at all particular in 

 their choice of food. 



Prof. Wyman announced that he had received other 

 fossil remains of seals from the Miocene deposit of Vir- 

 ginia, near Richmond, with the exception of South Ber- 

 wick, Me. the only locality where such bones had been 

 found. 



He had a large portion of a cranium, of a well known genus, 

 but of a species not yet ascertained. As these bones were found 

 at some distance from each other, farther discoveries would 

 probably be made. 



He had also received from the same locality an immense 

 Coprolite ; according to Buckland the usual size of these bodies 

 is about three inches ; this specimen was nine inches long, and 

 three in diameter. It contained fragments of bones ; and inter- 

 nally was of a bilious brown color, perhaps accidental. It had 

 a few marks of a spiral valve such as is found in the intestines 

 of the cartilaginous fishes. 



Dr. C. T. Jackson observed that he had received speci- 

 mens from Duxbury showing the extent of our tertiary 

 deposit.
