          lay by for him what I can which will be
valuable. Have you any quantity of Eaton's Sulphate
of Strontian [strontium]? By the way, have you a [?] [?] of
Topaz rock, or can I find any in N. York, in return for
any minerals I can send? Do you not get Zircon from
Trenton, N.Y., or, is the quantity small there?

I intended to say that probably Aspidm. [Aspidium] spinulosum was
mistaken by Mr. Eaton for Poly[letter crossed out]. hi[letter crossed out]org., not certainly - for I
had no certain means of determining. If I left out probably, I
did not intend to do it. My reasons are I can find no such Poly
pod - no such one was named while Mr. E. was here, that I know 
of  and, I have seen the indusium so [gone?] from the fruit on
many [leaflets?] that I should have misnamed, had not I found
a few with the indusium. All this is not proof  but
my opinion remains as before. If I visit Troy the coming
spring, I will on Mr. E's specimen. I have looked over
the brake family so much, that I know not where to
look here for that Polypod. Still I may get it another
season - at least, I shall look for it, as well as
to see if there be any yet unnoticed.

I should be glad of the minerals you mention from
WestChester, & thank you for the prospect of some
curious things. I hope you will not forget me among
your numerous friends. As to plants, I could dis
pose of duplicates very well. I want some of your
[?] plants - your [Solices?] - Carices - asters etc. And
I shall be [?] ready to send you all in my power.
As I have before said, my time is much taken up - 
but should some students, who have expressed their
wishes, still desire instruction in Botany the next
season, I shall devote more time to it, & again
be able to help you to what you want. Indeed,
I shall without this, to a considerable extent.

I am sorry to hear thus from my friend
James. He is a fine young fellow - & I hope he
will yet be successful. He can [?] in many
plans, I presume, the next summer, if he should
please. Botany is becoming popular, & tho' great
Botanists are not soon made, good may be done
