Dear Sir,

In answer to your urgent request for that
analysis of Zenite, I can only say I can not send it
now. I have just closed my lectures on Chem. for the
[fall?], & have been so hurried that I could not finish
that analysis. My family have been sick all this time,
Mrs. D. absolutely confined & has [?] left her room
for 10 [winks?]. This is abundant excuse, tho' I would
gladly let you have it. It would take me a few days
work to get it out, by odd hours - but I would not spend
my time now on the matter, to announce 20 minerals.
If I must be anticipated, I must. Tho' I give you full
liberty to do all you please, only you will say that
I [?] [?] [?] the thing. The case is just so
& I can not do otherwise but let me not stand in
your way, [?].

Emmons has sent me
[?] from [?] clearly so.

Swinitz [Schwinitz?] has sent me a copy of his analysis.
He puts on C. Alba & C. [alprstris?], which I sent him, &
which he says agree exactly with his Europ. sp.
C. pollisums, he agrees with me, is it. I am glad he has
left off the doubtful ones - but there one [?] more,
which he has not, as I think. C. ovalis, I do not believe
is here. Muh. has it not, tho' on the ground of it.
I have written to Swch. today & sent 3 or 4 more sp.,
whether he will call now, I do not know.

I am glad your name becomes mineralized, it
will stink, I hope.

You told me nothing about Cooper till now, & that only
