TO GEORGE ENGELMANN. 



New Yobk, November 30, 1841. 



Dear Doctor, — Don't hesitate about sending me 

 anything for fear I may already have it. Very many 

 plants pass through my hands while I am describing, 

 but my own herbarium is not very rich; and dupli- 

 cates will not oppress me. Mr. Carey does not keep 

 European plants except those identical, or supposed 

 identical, with North American species. Browne, 

 however, does, and I dare say would be glad to have 

 any you can give him. They are the gentlemen men- 

 tioned in the " Flora." . . . 



Eupatorium Engelmannianum, sp. nov. Am. Bor., 

 semina misit Engelmann. Can this be it, think 

 you ? If so pray help me to it ; and to anything else 

 you can, as I mean to give addenda et corrigenda to 

 the Compositse at the end of the order, if I ever get 

 through this formidable job. No wonder seven years' 

 labor at them ruined De Candolle's health. You know 

 he is dead? He died the 9th or 10th of September 

 last. . . . 



I send you my article in the January number of 

 " Silliman's Journal " with a little one by Sullivant, 



— by mail. I am extremely busy this winter, but I 

 hope always to answer your letters promptly, and to 

 attend to your desires as well as I can, whence I beg 

 you to continue your useful correspondence.

It is not a great while since I got aU the copy 

 ready for the number of the " Flora " now printing, 



— during which I could do little else. Immediately 

 this was done I completed an arrangement with my 

 publishers for preparing a handsomely got up Intro-
