clear and unafTectecl style of writing, and of 

 his devotedness to the interests of the Society. 

 Not only did he do this, but voluntarily under- 

 took to solicit the necessary subscriptions, in 

 which he had so far succeeded as to put his 

 final success beyond a doubt, when disease 

 arrested him. 



He was a member of all the scientific bodies 

 in this country; — the American Philosophical 

 Society ; the American Academy of Arts and 

 Sciences ; the Academy of Natural Sciences of 

 Philadelphia ; the New Yovk Lyceum ; the Na- 

 tural History Societies of Hartford, Salem, Port- 

 land, and many others. 



He was also one of the prominent members of 

 the American Association of Geologists and Na- 

 turalists. He had read several very interesting 

 papers at its sessions, most of which were des- 

 tined to form a part of his work on the Terres- 

 trial Mollusks. When, at the session of the 

 Association in Boston, in 1844, it was proposed 

 by several of our most intelligent citizens, that 

 the valuable papers which had been read should 

 be printed, and liberal contributions were A'olun- 

 teered by them for the purpose. Dr. Binney 

 was made chairman of the publishing committee.
