          Wms. Coll. Dec. 1st 1819.

Dear Sir,

Mr. Johnson of this town will hand you this. He
goes to New York to attend the Medical Lectures. He has studied
physic for some time with his [uncle?] [?]. Tho' he has not
obtained a liberal education, he has made some organisiations
in [?], & is a pleasant, agreeable young
gentleman. Any assistance or advice which you may be
able to give him, would be gratefully received.

Your letter of Oct. 1, with the cryptogamia came
to hand three days ago, after the short passage 7 1/2 weeks
from N. York. I thank you much for both. The plants
form a rich accession to my herbarium. And I am 
fully sensible of your kind attention & aid. I have
sent you plants twice since I have heard from you.
I hope you have recd. them before this. Also I received
the bundle you allude to in the last letter, but no
letter came with them, or, has yet come. While I repeat
my thanks for all the plants, I thank you for the prospect of any
more. I sent you some plants for Germany. But it is
singular I did, for I had not then your last letter, in which
you ask for some. But I suspect you got them too late.

You ask me to study the Lichens. You honor me, even to
mention it. But I should not effect any thing. I am so fully
aware of this, that I can not think of setting about it. If I had
time, I might perhaps consider upon it. Indeed two years ago,
the very project came into my mind. But my multiplied duties
here, my want of means, distance from collections of books,
& [?] [?] thus engaged, with a deep but just conviction
