40 EARLY UNDERTAKINGS. [1833, 
County, N. Y.; the same as published in fifth. edi- 
tion Eaton’s “ Manual” under the name of R. pro- 
stratus, Lamk. I have never seen their specimens, 
but have little doubt it is a form of R. repens, which 
flowers with us from April to September and assumes 
many forms. Dr. Beck wishes me to send him any 
undescribed or interesting plants, localities of rare 
plants, ete. eel somewhat interested in the work, 
as I wish it to supersede Eaton’s entirely. (I hear 
Eaton is coming out with a new edition in the spring. 
I see Beck means to anticipate him.) But all the 
undescribed plants I have are in your hands, and it 
would be improper to send him such at present. He 
has in his hands an imperfect specimen of Nasturtium 
natans, De Candolle, which I sent him two years ago. 
He did not know it; supposed it N. palustre, ind I 
do not know whether he has determined it or no. I 
will tell him what it is. He has that Ophioglossum 
and probably will publish it. If you please you can 
publish this, that Seleria, ete., in Silliman, that is, 
if you think them new. I will send none of these to 
Beck, but will give him the localities of some of our 
most interesting plants. 
I have not heard from you since I wrote you on the 
subject of your letter, but hope you will write me 
soon. If we can make any arrangement for a year, 
by its expiration you will know whether or not I 
shall be of any use to you. I wish to be situated in 
such a manner as will enable me to advance most rap- 
idly in science, in botany especially. 
I succeeded, some days ago, in making the chloro- 
chromic acid of Dr. Thomson (of which you spoke to 
me when at your house), with chromate of lead, in- 
stead of bichromate of potash, which I was unable to
