 Nat Gaz no 1981 (1833). In this last he has given some fine
 touches of genius. In a Botanical review I lately
 read in the N Amer Rev [North American Review] no 82 p 41.  I was pleased 
 with an extract from Cuvier but know not [crossed out: when] on what accasion 
 it was written any farther than it being in praise of 
 Botany when he said "that in the Science of observations 
 botany created an epoch as important as the 
 Chemistry of Lavoisier in the Science of experiments."

 If you should be writing soon to Dr Darlington of Westchester
 say to him that I found one or two specimens of (the true) 
 Salix recurvata of Pursh in Hookers Herbarium send by him
 but his specimens want the [mas?] ament this is much 
 wanted perhaps he would kindly exert himself to 
 procure it for you or me There were some other
 willows in his Herbarium without flowers but I was
 so fortunate as to find the same growing about here 
 last fall procured the leaves and shall this spring 
 look sharp after them myself. I thind you had better 
 not delay writing to Dr Darlington about this matter even 
 if it is only a line at the same time you could 
 ask him to give a sharp look out for such things 
 my attention this spring will be directed mostly to the
 Willows with glacous [glaucous] leaves such as Eriocephala 
 Muhlenbergiana [Trustis discolor?] &c I find great
 trouble with the earliest since there are many 
 varietes [varieties] and some curious facts in relation to 
 them having watched them for years and now 
 knowing all the trees and their exact localities I can 
 go direct to them, and compare their times of flowering
 from year to year. 


 Yours truly 
 J Barratt.
