Dear Sir,

I have the pleasure of acknowledging the favor
of your letter of the 7th inst. [instant] containing very many names of
plants I sent you. In Cryptogamia, I think this plan tells well.
I shall doubtless find more another season, unless I have too much
work to recognize those you have already named. Several of the
names I do not see in your Catalogue. The fungi I found
would spoil, but they were so dry, I hoped not, & I want to
know them if possible, but it is well. I only regret their bad
state of unpleasant smell. The plants, yet unsettled, I hope you
will find out. I will mention some, you have not noted, of
which I wish to hear, by & by. I have kept all my numbers as
yet distinct, so that I have had no difficulty in determining
which you meant. But they have become so various,
that when I send many more, I shall perhaps find it [?]
to throw away old numbers. You do not speak of the
[Salices/Saliers?] specifically. I tried my best on those from Eaton, &
could do no more, but supposed some were wrong in all
probability, as they are so bad to get at, & I want your
remarks on them. Am glad of any were new to you. I think
I have looked up all of them here. And I hope to get the
flowers of all in the spring in good state.

Siderographite is a good, tho' long name. I should however 
be pleased with Gibbsite. Minerals grow [scarce?] for
[some? new?] names, & I should be glad to honour that Mineralogist. 
If it will be pleasing to him, call it by his name.
Has he yet recd. [received] my minerals, or would not he [ought?] them?

I hope Eaton is now right, but truth must prevail, &
the [sulph.?] of [Borytis?] be so, if so it be. Zircon is not in
this part of the country, that I know of. I have not even
a specimen, which I much need. I have no belief that
it will be found in Brimfield in any abundance. It is
a rare mineral, & for a [bare?] specimen, I should be very
glad.
