          present. He has in his hands an imperfect 
 specimen of Nasturtium natans, De Cand. [Candolle] wh. [which] I sent him 
 2 years ago. He did not know it, supposed it N. [Nasturtium] palustre
 & I do not know whether he has determined it or no. 
 I will tell him what it is. He has that Ophioglossum
 & probably will publish. it. If you please 
 you can publish this, that Scleria&c in Silliman
 ie. [id est] if you think them new. I will send none 
 of these to Beck. but will give him the localities 
 [&c?] of some of our most interesting plants. &c &c


 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 rapidly in science
 in botany especially.


 I succeeded, some days ago, in making the Chlorochromic
 acid of Dr. Thomson (of which you spoke to me
 when at your house). with Chromate of Lead.
 instead of Bichromate Potash. which I was. 
 unable to obtain. It. set alkohol. Ether.
 Spts [Spirits] turpentine &c. on fire. I did not try it upon 
 Phosphorus. Shall prepare it again in a 
 few weeks for class experiments.


 I am, Sir, 


 Yours Respectfully
