          I have some minerals which I may send. Perhaps 
few new ones, but better specimens of some I
sent  you. I have taken pains to get some, with particular 
reference to you. I had hoped to receive some
from you & the Lyceum. They might be valuable to me,
as I am now lecturing on mineralogy to a class. Have
brucite to spare me, &, I might mention others.

I have also analyzed the mineral from Carlisle N.Y,
I had hoped to tell you of the misnomer. Do you find
a little [lime?] in it, as well as much [barytes?]? The mean
sp. gr. of six specimens was about 4.4, tho' I found another
one a little below 4. I think also it is a new variety
of fibrous sulph. [sulfate] of [barytes?].

In Jan. last I visited a spring, in this town,
whose temp. was then 60°, ground partially frozen,
& no snow. Frogs were hopping about in the [page torn: wood?]
& two striped snakes were in it also. I think, [page torn; as? I?]
hinted before, those animals do not pass into so
torpid a state in winter, as has generally been
supposed.

I congratulate you on your discourse
in relation to the brucite. A new mineral is rare. I
suspect I have a new one, but will not say so yet.

Has not the Lyceum enough of those crystals of
quartz to break one, to [expt?]. on the fluid it contains. 
I have only one, & I wish much to [try] the
liquid. May I expect to hear from you soon?

With respect, yours &c.

Chrysosplenium oppositifolium is now in flower,
& one of Salix nearly out, probably Tussilago farfara is
in flower, it grows with in [?] [plains?].

I have had brought to me a lobster, about 2 inches long, found in our fresh
streams in abundance it is said. I never saw one before - are you familiar
with the species? & what is its name?
