Dear Sir,

I avail myself of Mr Tuckerman's return
to Boston to acknowedge the receipt of your
letter of May last which I received through Dr
Heister. I trust he was pleased with his short stay
in this great capital. It will always give me great
pleasure to see and be useful to any of your friends
and I do not despair of hearing, that one day or another
you may yourself undertake a second voyage to Europe
and that I shall have the gratification of making
your personal acquaintance. The geological reports
of the State of New York are exceedingly interesting and
I am very much obliged to you for having sent them
to me. I was once a good deal of a geologist, as proof
of which I send with this a letter which I formerly drew
up on the generalities of the Canarian geology & which
I have since developped in our work on those islands. But
I am now a miles emertius of that troup  [crossed out: and] occupying
my time solely in botany, and your botanical catalogue
