Prof. Torrey, N.Y.

Dear Sir,

From the public papers you know perhaps, that my little 
book will be printed by order of the senate. The printing
of it will com̃ence [commence] probably in the course of this 
week. The enclosed papers contain the botanical appendix, 
written by Dr. Engelmañ [Engelmann]. I received them but a few 
days back. He advised me in his letter, to send his manuscript, 
if time allowed to do so, to you, to correct perhaps 
four mistakes com̃itted [committed] by him from want 
of botanical literature. I take therefore the liberty to 
send it to you for your inspection, with the request 
to make your remarks on a separate sheet of paper,
to write them as distinctly as possible and to send 
the whole back to me within a week. Of the error
in regard to the new genus Wislizena [Wislizenia] Dr E. [Engelmann] is
already informed.

Give my best respect to Dr. Le Conte.
Most respectfully 
yours 
A. Wislizenus
(at Mrs. Peyton's Washington
City. D.C.)
