          Halle 1820, Jul. [July] 5.

Dear sir,

Your friendly, indefatigable and unparalleled carefulness and diligence 
in furnishing me with plants of your country and procuring me the 
valuable correspondence of those gentlemen, who with the same humanity 
and benevolence you are possessed of, with as much zeal for the 
promoting of that fascinating science, to which I have consecrated my 
life, requires my hearty and during thankfulness. I have received 
your kind letters of Feb. 2 and March 17, the latter being accompanied 
by a package of yours and of Dr. Halsey. But the box 
your former letter speaks of, is not arrived till I reclaimed it from 
Holland, on whose coasts I am informed the ship did [stand?]. This 
is the reason of the retardation of my answer. Now, being in 
possession of all the books and collections of plants you and your 
friends had the kindness to favor me with, I feel myself highly indebted 
to you, and I wish nothing more than to be thankful to 
you and to [can?] prove my feelings towards one of my most beneficent 
correspondents.

I have the honour to offer you the accompanying
