Respected Sir,
Yours of Aug [August] 18th was received,
and many thanks to you for the information
it contained.

I have got Bot. [Botany] of Beechy's voy [voyage], where 
Adiantum Chilense is noticed as from Conception, 
Chili. We found it abundants in the vicinity of 
Valparaiso, and as I said before, I have seen
it mentioned in some work, as being a native 
of Calfornia, and I believe in some of Sir 
Wm. [William] Jackson Hooker's [serap?] works. 
I would give almost any thing to have Gaudichauds 
Bot. [Botany] of Freycinets voy [voyage]. We have every thing 
in Wash. [Washington] of that voyage but the Botany. Do 
you know if it to be be had in Philadelphia?
I shall fee very much obliged for 
the loan of Agargh's monograph on Pteris. 
if you could send it on by Adams Express, 
it shall be taken good care of.

I regret very much that you did 
not see Captain Wilkes, on his way North,

to talk over with you, regarding the botany of
