Letter from Dr. Torrey to Professor Douglass. 
New-York, August 4, 182]. 
Dear Sir, 
Inciosep I have the pleasure of sending you a cata- 
logue of the plants from the North-West, which you for- 
warded me some time since for examination. Many of the 
species are very rare, others are from entirely new locali- 
ties, and the whole are valuable in increasing our knowl- 
edge of botanical geography. To those species which are 
but little known or imperfectly described, I have added 
such remarks as I supposed would be useful. 
The Indian and popular names and localities are taken 
from your notes annexed to the specimens. 
With great respect, 
I remain your humble Servt.
