My Dear Doctor

Your favor of 22nd came this morning.
I am out of breath with a lecture 1 1/2 hour long. &
so set down to reply at once.

I have written
to Mr. Lowell for [Eriog?]. gambell, but have not yet
received an answer. You did not ask for descr. of
the other 3 species of Pl. Voy Sulphur, or you would
have had them.

I have none of Engelmann's Eriogonum atrorubens.
Write to him for it.

I do not care which of the
two genera you mention is given to Sprague. Take your
choice when you get the drawings. If Sprague
has time I was going to have him engrave the gen. [?]
[?], on the same stone [crossed out: with] which the Fremontia
is on. [crossed out: In the] (adding some more details [crossed out: of] [added: to] the latter)
In that case that stone should be worked here. I am
sorry you promised Endicott the printing of these plates
for (if not done by Prestele's [crossed out: himself] new man) I think
[?] press-man here would have done them better.
but perhaps not.

I will hurry Sprague to
finish the drawings, and you can [crossed out: have] yourself manage
the engraving & press-work as is most convenient & proper.

I am very sorry that there should have been any misunderstanding
or dissatisfaction on Prestle's account. I have a very high
