          but, we have every reason to believe that the Gray Wacke [graywacke]
is the rock next above the Argillite at Troy, & [alternates?] with it,
& is as much a stratum as the Argillite. As yet, I am not
ready to subscribe to his notions.  I intend to examine more
in the course of the season, & on how he is mistaken.

The new Mineral of which I wrote you, turns out
to be an oxyd of Titanium.  The mineral might be obtained
so as to afford oxyd enough to be reduced, & afford the metal.
I have lately rcd. [received] Wollaston's Goniometer. But it is an
exceptionally troublesome instrument to use, as the eyes must
be so near the mineral & I should think it could be of
no great use, & would not be used, except in rare
cases.  Some other instrument is very desirable, if [?] be
consulted in determining angles of crystals.

I wish you would send me more of the the minerals in
your neighborhood.  I want specifically Rubellite in Limestone,
Actynolite [actinolite], your asbestos or Tremolite, Carb. of Magnesia,
& hydrous [Mognific?] [?] - Nuttall's Nimalite,
& Marmolite -Phosphate of Lime, Fetid Feldspar, etc.
I shall in the spring send you some Minerals,
& to get more, I want some of yours.  I hope to get
some from Mr. Schoolcraft by and by.  I have not
dendritic mineral - perhaps you got hold of such, & can
let me have a good specimen.

In the New Ed. Encyclopedia, is, as I suspect, Jameson's
Minerology.  Certainly, it is very good in some respects,
no Am. [?] as I have seen.  I want a piece
of Basalt much, very much.

Our new President [?] finely -&, we are likely
to live on.  I wish to know whether you hear of that
box of plants, & am with high respect your friend

P.S. No wonder you complained of the spelling etc. in
Silliman's journal.  It was horrid in your [?], &
bad enough in [?] [?].
