Dear Sir,

Yours of the 4th just came in due time. I embrace the
opportunity of answering it by Dr. Hooker, who starts for tomorrow for New Haven.
There is another letter of yours, dated Sept. 7th  last which I received after
my return from the country, that should have been answered long since, but
it got mislaid. It seems my paper on the new Lichen [was?] too late for
the last No. of your Journal. Should you incline to give it a place in the 
next No. my friend Dr. Hooker, who is an excellent botanist will examine the
proof sheet.

I thank you for your kind attention to myfriends Dr. Smith & Mr. Linberg
they feel much indebted to you.

You are right about that mineral I sent you from Fishkill. It seems
to be nothing more than a fine grained trap or or perhaps a gray-wacke incrusted[encrusted]
with anthracite. It was scarcely worth your notice.

If possible I will select some Sparta minerals for you tomorrow, but
it will not be in my power to lend you much now. I wish Messrs.
Keading & Vanneven would publicize their account of these minerals, that
I might see what they have to say, for I fear to send you any remarks
(many of wh.[which] I think interesting) on them for fear I shall be thought interfering
these gentlemen.

Respecting my remarks on the Hoboken minerals. I could ask your
opinion whether they would be of sufficient consequence to communicate to
the public if continued in the way I conceived them. If you think they
would, please retunr what I have written by Dr. Hooker & I will send
you a complete paper immediately
