Dear Friend

I suppose you received my Index
to Geology. I do not expect to have
justice done me, respecting that pamphlet
by an person in N. York but Doct. [Samuel] Mitchill
and yourself. The labor was immense but
I shall be censured for not following European
geologists in a more servile manner. To have
done this I must have shut my eyes to 
truth and common sense.

I want your catalogue now very
much. But if it will surely be printed
by the midle of March you need not
take the trouble to give me a manuscript 
copy.

I am now giving my fourth course
of lectures in Geology and Chemistry for
this winter. You Yorkers who have every convenience
about you know very little of the
immense family of children brought forth
by dame Necessity. I give most of the
experiments of Henry and [?] with
about 50 dollars value of apparatus.
