          I despatched by the last Santa Fè mail a letter to Dr Engelmann
with a request that he would forward to you Dr Gray & giving 
some account of my travels and discoveries in Northern Sonora.
I hope soon to have time to give you a detailed account of that 
excursion in which I collected many things which I have no
doubt will prove interesting.

I received along with your letter one from Mr Carter
giving me some brief directions for preserving Fungi.
I have writtne you already on the subject of books. In your
letter you speak of your labors on Dr Parry's collections. I 
hope you will not forget to secure me a copy if it is in your
power. You may find me an incorrigible book-beggar. Well
I need them. I ought to have a few comforst to relieve the many
hardships & deprivation which I have to endure.

It is now about a year since I last heard from Dr Gray.
Tell him I shall expect him to remember me among his
first friends whom he favors with [added: a] scrawl from his ugly fist.
I want a work on the Marsupialia. Is there any of small
or moderate size that you could send me.

I believe I acknowldeged the receipt of the books you sent me
for Col [Hoyle?] as well as the Annual of Scientific Discovery though
this last is not the one I sent for (as you will see by reference
to my letter) having previously received it from Dr Gray. I wished
for the vol. of the present year and would yet be glad to have it.

I don't expect you to be at this trouble and expense for nothing. 
If you will jsut keep a memorandum of such things as you 
may sendme or have already sentI will direct Dr Gray who
will probably have some funds for me on his return to repay
you. I want everything relating particularly to the plants
of this region that can be procured, if of portable size & weight
regardless of expense and when my collections come to [harm?]
just repay yourself to your satisfaction.
