          Colunbus Ohio Septr 1st 1840

Drs. Torrey & Gray

By the bearer (Mr. Platt)
of this I send a small parcel of plants for
your examination. In a few weeks
or a soon as the season for collecting is
over I shall send you a large number of our
Ohio plants as I mentioned in my last 
letter to Dr. Gray. It was my intention 
to have sent by this opportunity a set of our
mosses for Dr. [William Jackson] Hooker but I have not had
time to put them up. It is surprising
what an amount of labor & time is [?]
in collecting, preserving, examining, arranging etc. 
a large number of plants, as you well know.

Dr. Torrey sent me last fall a copy
of [Dr. C.A.] Agardh's Systema Algarum which I fear has
proved to him a troublesome present, part if it 
is still missing. All is complete & including
the XXVIII page ending with "fructus tantum differt"
from thence on all is missing to the 17th page
beginning with "hoc cm seguente" etc.  The rest in complete.

The 3 col. of Hooker Icones Plantarum
& the 11th no. of the Flora Bo. Am. [Flora Boreali-Americana] came safe to hand
They are the most interesting parts of the two works.
Dr. Brotts doings among our Carices are quite
