clear and unaffected 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 York 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 volun- 
teered by them for the purpose, Dr. Binney 
was made chairman of the publishing committee.
