formation on their geographical limits ; to William 
Cooper, Esq., well known by his devotion to the study 
of ornithology ; to Mr. Oakes, of Ipswich ; to T. W. 
Harris, M. D., Librarian of Harvard University; to 
S. C. Greene, Esq. of Boston ; and to Mr. Nathaniel J. 
Wyeth, Mr. James Brown, Mr. John Bethune, and 
Mr. Russell, of Cambridge. 
The wood engravings, not sufficiently numerous, in 
consequence of their cost, have been executed by 
Mr. Bowen of Boston, and Mr. Hall, in the employ of 
Messrs. Carter & Andrews, of Lancaster. 
A larger work on the Ornithology of the United 
States, with numerous engravings, and more extensive 
details of Natural History, will also soon be issued, so 
as to complete and embody, with every necessary il- 
lustration, the History of the birds of the United States, 
and of British America.
