          time to examine them this summer. Indeed I have
done nothing in Botany this three weeks. The C.
oligocarpa, I have found this year I hope. The one I used
to call so, I saw was C. varia. Carex senta grows here
so differently in its appearance, & so like the C. cespitosa,
that I an often at a loss, & I send it to you just as I [?]
when I examine it. In one place I know it - in another
it grows like C. cespitosum, & not in a bog, & its characters
are much less distinct to my eye. I wrote to you a while
ago, that I had C. bromoides it is what I had called C. sterilis.
But C. paniculata is very difft. Eaton says, C. bromoides grows
on dry ground, I think - your Cat. I believe, is wet this
grows in small bogs. I hope you are right about C. trichocarpa.
By the way the habit of C. pubescens is so difft [different] from
that you called so, whose leaves are not pubescent, by very glabrous.
that they need looking at again. C. [?], I
shall send you in abundance.

I shall send you a set of
our Carices, as you wish at least, all that are not well settled.
I hope to get a box to you about 10 days hence but you
will hear of it when it gets to N.Y so give yourself no
[uneasiness?] about it, till you hear more. The man may not
take it, & my [business?] may prevent me putting them up.
I have not all my time lately one of our officers is un
well & another about a day or two - & my works must got on
in College [hence?] Botany must lie by. And I am [slow?]
it & have lost the [zeal?] you liked a few weeks ago.

I shall send you minerals - Chlorite & chlorite [Slate?], to your
fill. I am now handing off 3 or 4 boxes- these are completed
& one to the Geol. Soc. is on hand. I want to [charact?]
[?] too for I have been so buried in rocks, that I
can no longer delay clearing out.

I have lately had a short visit from Mr. Hitchcock
of Deerfield. He is a preacher and attends now to Nat.
Hist. only by the by. But his activity of mind is so much,
that he will accomplish no little, I think & hope.

I have just recd. fine Nodular Argil. Iron Ore from
Baltimore - some Carnelian - & petrified wood from
the Sandstone on the Potomack.

Is not ore of Cobalt
sold in N. York, from which sympathetic ink is made? I
got some a while since but it was an ore of arsenic
& iron, I believe, & no cobalt. I have the [arseniate?] from
Can. but I want more of it for the above purpose.
If you know of any, I would purchase some gladly.
I want ores much the [sulpherent?] of copper, I have not,
altho' more than one specimen has been sent me
for that.
