          pseudomorphous anything. I have such crystals, that I
know it can not be so. I shall be able, I hope, to satisfy
you ere long. I shall hold out, to be sure, on those crystals
at Middlefield I can not do otherwise &, I can not see
how any one can doubt. I have good authority to hold me
up if any be needed for Jameson does not convince
many that those of [Europe?] are false crystals.

I wrote you the other day & told you of my views
of that box of minerals. I have not had much time to
examine them, I was obliged to look a little.

Most of the alterations in names, on those sent before,
I had already made. Some of them I had previously
mentioned &, I am glad you have mentioned them to me,
that I might have the whole before me. I do not find
Spinelle & [Hypusthum?] on your labels but Spinelle in Hornblend.
[Green?] Feldspar I can not find it do not know what
you mean You sent me green Feldspar from
Long Is. a while ago I recollect no other.

Laumonite [Laumontite?]? I was well persuaded it could not be, & suspect
more examination will prove it to be Zeolite.

Scapolite. Puzzels me much looks like Augite some
of it [?] pretty easily & others [scarcely?] at all. And on the
Augite, I found just such [differences?]. I suspect, it will
all turn out to be Augite, perhaps a subspecies. I
wish you would analyze it, to be sure.

[Dysluite?]. Do you mean that you called Augite in Carb.
of lime, with Spinelle, I believe.

If your crystals from Litchfield are in Dolomite, the
mineral has long been called white pyroxene. If not, I know
not what you have. It may be pseudomorphous for
some things are so, & some are not, & I can say both
& laugh or be sober. Silliman would not talk on it,
