          nitrate. But I am willing to say, it is
possible that my salts were imperfect
and that the flame was as of simple alcohol, if such a concession is necessary.
With respect to spec.[specific] grav.[gravity] I have found 
it under 3.5 and over 4.5. Not one
half of you know how to take the spec.[specific] 
grav.[gravity] The thread by which you suspend it
often deceives you. Cut a small neck on a
corner of the specimen and tie a hair around it. Then
let it sink crossed out: both] [added: several] times so as barely to cover the
corner. Set in just consider a case. The thread
shall buoy up two grains. In air the specimen 
weighed [80?], in water its true weight is 10. The
spec.[specific] grav.[gravity]  would be above 1.14+ But if two
grains are supported by the thread the spec.[specific] 
grav.[gravity] would be 1.111+ I find my European 
specimen of baytes and strontium both [above?] that
given in books. also my American specimen
of barytes from Southampton. That from the
Little falls agrees tolerably well. However I have
not had time to do the subject justice.

I am now on my way to Hudson.  I remain
in Hudson two weeks, then I am at Troy &
Waterford three weeks. So I go on till October. Tell
Dr. Townsend, that I received his letter, devoted to
the case of the Mayor of Hudson. I will write him
when any thing new occurs.

I wish you could send the Troy Lyceum some
of your [Gungermannias?], mentioned in your catalogue.
We will send you anything we have, that
you want. We have two species of [Synimbrium?], the
amphibious [apahyte?].

Yours

Amos Eaton.
