          long been convinced that the Neptunian Theory must go down - &
I do not believe Vulcanian will be adopted in all its [extat?].
Some middel course, or some new Hypothesis must be formed.

Can not you find Playfair's llustrations of the Huttonian Theory,
in N.Y. & get it for me. I want it much. It seems to be established
that Basalt & [Grinstone?] etc. must have had an igneous
origin, at least, as fully as the case will admit, & that those
minerals come from the depth of the oldest Granite.

Prof. [Green?], I do not know - his remarks on the yellow
Bird are odd enough to one who has ever seen the animal as
he describes it. Silliman's Journal is better but that [?]
[?] is little enough. In the 1st vol. I had given
account enough of the Snow Hole on the Mt W. of us. [?]
the Min. of this town in that Vol. And I was surprised
to see that letter from Dearborn, & commentary by [Ives?] it
is all little enough. Where do you publish your account
of the Hydrorgillite ?

Hayden has entirely demolished the old notion,
of formation of soil & alluvial from the disintegration
of rocks. His reasoning is very powerful to my mind - I
want again to read it, & shall, soon as time permits, to
see if I can detect any fallacy. But I was amazed at
what he collected on the subject.

I am now fitting up a box of minerals & plants &
bugs for you. I can not send by Mr Wright, as he goes over
land too far & round. This letter will get to you in a week - &
if possible, I shall start the box for the Steam Boat next 
Tuesday; if not  then, the Tuesday after. Do make up a
load for me by Mr. W. - a box of any size he will get
along.

I want Playfair's Illustrations, & then, as you
see, I shall be ready to be a Huttonian, on a modified plan.
I think of illuminating the work on this hot point. All this is fun.

I found Chrysosplenium oppositifolium in flower [from?] 10 days since
I rcd. Schwinits [Schwinitz's?] work from your hand,  & am much obliged. I am
greatly pleased with the plan. He is better than any author
I have read on the [Hipotics?]. I wish he might go on with it.
