          in Dict. Sc. Nat. vol. 29. p. 174 when I suppose
 the etymology is given.  If that dictionary is in
 any of the libraries, within your reach, I shall
 [illegible] it a favor if you will procure me the
 desired information - that is, supposing you do
 not already possess it.  It is, to be sure, a very
 small matter; but as it is the only genus, with
 a modern name, in my list, of which I have
 not the derivation, I feel the more desirous to obtain
 it: so I hope you will excuse the liberty I have taken.


      I have not heard from Dr. Grey very lately;
 but I am in hopes we may expect the concluding
 number of the second volume of the N.A. Flora,
 sometime in the ensuing Spring.


     I do not know whether you every had an oppor:
 tunity to get a copy of Dr. Baldwin's Correspondence.
 If you have it not, I will take the first oppor:
 tunity to send you one.  There was but a small
 edition published - & I have a few (being all that
 are left) yet on hand, which I propose to dis:
 tribute among Botanical friends, & in public
 libraries.  I have send a copy to Princeton's
 library by Mr. Crowell. - Hoping for the pleasure
 of hearing from you before long.  I remain
               very sincerely your old & obliged friend
