60 EARLY UNDERTAKINGS. [1836, 
A letter which Dr. Torrey has just received from 
Mr. Arnott gives me the information that you have 
honored my attempt at a monograph of Rhynchospora 
by commencing the reprinting of it in the “‘ Companion 
to the Botanical Magazine.” I might justly be proud 
that my first attempt should be thought worthy such 
notice ; but I wish it had been delayed until you could 
receive the monograph “ Cyperacez of North America” 
of Dr. Torrey, in which I had occasion, in the revision 
of our Rhynchosporz, to make some important altera- 
tions and corrections, as well as to introduce a new 
species and specify some additional localities. The 
paper referred to I hope you will receive with this 
letter. 
Except a few extra copies, all the sheets of the mon- 
ograph “ Rhynchospore ” were destroyed by fire soon 
after being printed, and when reprinted, about a year 
since, I added a few observations, notes of additional 
localities, ete. But owing to a want of careful revi- 
sion I find there are several errors (several of which 
are quite material), some of the pen and others of the 
types. I hope these have been detected and corrected 
in the course of the reprint. I send herewith the 
sheets of the paper as published here, with such typo- 
graphical corrections as now occur tome. Would it 
not be proper to append a reprint of the revision of 
Rhynchospore in Dr. Torrey’s monograph, a copy of 
which I hope will reach you with the present letter. 
If the specimens I send please Mr. Webb I shall be 
glad. It is the last perfect set I have. Please make 
no remittance, since the sum is too trifling, and more- 
over I may soon have some favors to ask as to its dis- 
posal. Indeed, I know not why I should not state 
that there is some probability that I may soon visit
