TO GEORGE ENGELMANN. 



NEW YORK, 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 Compositae 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 all 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-
