Dear Sir:— 
Will you pardon the liberty which I, a stranger to you, have

community of the country owes to you for your unexampled liberality 
in purchasing the splendid collection of birds now in your possession, 
and of placing it in a place so accessible to everyone as the Acad. of

of North American birds. Had I gone to Paris, my first visit would 
have been to this collection. Judge then of my delight when I heard 
that it had been brought to our own doors. Heretofore when Ameri- 
can ornithologists wished to do anything in their favorite field of 
science, they were prevented by the want of specimens for comparison, 
and of books for determining the validity of their discoveries. Now, 
if I did not misunderstand Doctor Morton, what in time will probably 
be the finest collection of birds and of ornithological books in the 
world is thrown open to us. I for myself am waiting impatiently

as I have several monographs in preparation, with drawings, which 
I cannot complete until I see those species you possess which are

great generosity and extreme modesty. He died Mar. 15, 186s.
