          I am glad Eaton visited you & his Manual will, I have
no doubt, be better for it. He is now lecturing in his
Professorship in great style, & with much eclat. He
lectures 3 times a day, on Botany, & Chemistry, &
Medical Jurisprudence, & then spends an hour in
examination of the students. Emmons is with him 
says there are about 40 medical students - fine
fellows - eagerly in pursuit of knowledge, etc. etc.

I can hardly believe that the Wavellite analyzed by
Davey is the same with that on Berzelis tried.
If so, Davy was greatly mistaken indeed. At least, it
will be necessary to try the W. of England again. I think
[Choveland?] says, a little fluoric acid was in it - & some other
ingredients. I shall, by & by, try the Richmond mineral
again. I meant to try it before now - but I have been
too much hurried in my usual course of chemistry.
The atomic theory is about as short a cut to Chemistry
as the royal road is to Geometry. Both are about as
[?] - & about as sure to fail. The former is built on
[?] hypothesis - & the latter is imaginary. The theory
of definite proportions seems well established - but the
atomic fellows split their indivisible atoms, & hardly
any two agree in splitting them in the same place.
I make no objecton to the doctrine of atoms, after all this 
but think they are rather too minute to be bandied about
as they have for a few years past.

Emmons sent me fine specimens of pseudomor
phous crystals of Steatite. You doubtless have the
same.

I hope you had a fine trip through the Barrens &
found all you wished. And what news do you
bring from Phila., & did you not on that [Hartinum?]
