but know not where to send to him.

Emmons was
here some weeks since, returning from Medical Lectures
in Vermont. I hear he has been invited by the people
generally to settle in Chester, adjoining his native Mid_
dlefield, & that he has begun to practice there. I can not
yet vouch for all this -but I have reason to believe it.
He found topaz in Middlefield - he has sent you some, I
believe. His is very small crystals, in [connection?] with the
Serpentine, & in disintegrated Serpentine, I suspect. I call
it topaz, from its hardness & colour etc., & general resemblance
to the fine topaz I saw in Webster's Cabinet. I can
send you a [?].

I had recd. no plants from Cooley when I wrote you,
except one grass, [?] etc. which he said you did not name,
but which seems to be an Agrostis in Muh. according to my
short look at it. I feel confident that C. conoidea can not be
No. 2. No. 4. is very difft. from C. [sortrola?] I hope it
is really difft. C. disperma varies in height, but
it is always so like itself, that I never mistake it
both high & low have occasionally 3 [buds?]. The specimens of C.
muhlenburgii are very poor - I think with you it is not that
but it grows in a place as difft. from the places of C. disperma,
as you can conceive, & I suspect it is a variety of our variety of
what I called C. [?].

Viburnum prunifolium is a [tree?] 8to 10 feet high _ I supposed V.
lentago, a shrub. But I overlooked it strangely - & know how
it was. The Onoclea, I give up a hopeless. I sent the same
one to Sprengel, & he calls it Struthioptris germanica.
That Prunus nigra, grows in cultivated fields, & some hundred feet
up our hill, in the borders opf woods & along fences, & in the
valley - in many of those places, it was never set out or planted,
but by itself or birds. It bears a [crossed out: brownish and] plum brownish - and on
one side & white on the other, generally wormy, or knotted, so that
[?] on fair - not pleasant at all to the taste, unless very [?]
It grows in other parts of the county in the smae way. It is only rarely
cultivated. This is all about it. I should suppose it must be
about you, if [?] an exotic. Yours with much respect C. D.

That Erigeron purpureum, as I have it named, seems like that in Eaton, more than like
his philadelphium - but I doubted, tho' I supposed it was not the latter. Its flow_
ers [come?], & [are?] gone quickly - so that it is [bad/hard?] to [?]. I have another [mess?] of [?].
for you in the box for [Princ?]. Do write me what I [wanted?] in my last, as well as
what I ought to know in this. I am a member of the Linnaean Soc. Boston, but I shall,
keep up correspondence, as usual, with you, as a matter of course.  C. D.
