          some general system upon the plan of Persoon's, but more
 extensive. Decandolle's [de Candolle's] Prodomus (I believe he calls it)
 in 4 vols. 800. comes nearest what I mean. Can I get
 anything better than that and if not can you procure
 that for me from Paris with the Organography of the 
 same author that you refer to? These (if you can get them
 so soon) and also Elliotts sketch. I shall have an opportunity
 of sending for in the course of two or three months
 by Mr. Brooks and Lady who visit your City on their
 way north. And if in the interim you will let me
 know how much you will have to expend in executing
 [inkblot: these?] troublesome commissions I will send along in two
 [?] by him. The flowers you were so kind as to
 forward to Balt. [Baltimore] for me have not reached this place 
 yet. Have been waiting for a safe opportunity. Shall
 probably receive them in a day or two. 


 If you knew the 
 pleasure your letters afford me you would excuse my requesting
 you to write often to 


 Yours most sincerely


 W. E. Aiken.


 P.S. If you are ever at a loss where to find me, just direct 
 your letter to Troy, N.Y. and my friends there will forward
 it.


 Do you know the character of Sowerby's Mineral Conchology?
