          Washington City, April 4th, 1845

My dear Sir,

I have the pleasure to acknowledge
your last letter of the 31st containing your
final determinations. I trust with you
that we shall not find it necessary to
make any sacrifices at the end of the next
campaign - at the same time it is really wonderful
to see that you have been able to 
make out so many of this collection, but
the beautiful condition in which you will
see those of the next, will be some
amends for your labor. As we do not
publish any appendix, I suppose you will
think it not advisable to annex Dr. Grey's
pamphlet to New York. I hope that you
will succeed with the plate of the Fremontia
you know that can always be put in
at the last hour. We shall require
certainly ten thousand, & probably twenty
thousand impressions. I enclose a
little note, on which I beg you
to just the answers to the questions, if there
are any, and enclose it back to me. They
