Dear Sir,

Yours of 6th reached me in due course.
I am glad to learn that the Box was found in good
condition. The manuscript copy of "Wilson's criticisms"
is intended for your convenience. I copied them from
the Journa of Botany kindly loaned by you some time
since. I think I returned the Journal while you
resided at Princeton.

For the "Contributions to the Smithsonian Institute"
be pleased to accept my sincere thanks. I received them 
yesterday not knowing how they were forwarded as I did 
not see the person who delivered them.

I am very glad to have description and drawing of
Darlingtonia Californica.

I do not know when to find Bruch & Schimper mosses.
There is not a copy in the Academy! At least there was
not last Octoebr.

My time has been altogether take up with business matters
since I came here but I hope soon to find a little time
to look in at the Academy.

Mr. Wilson of England has some new mosses in ahnd
which I am anxious to hear of. They were sent here by
my friend Thos. P. James Esq. last fall. He had reported
upon a few previously sent and said he would undertake
all that might be forwarded.

I regret that Mr. Sullivant cannot find time for our 
new mosses as I would greatly prefer that American mosses
