THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 135 
expedition to the Grandfather mountain this spring, chiefly with a 
view to Cryptog.—but unhappily have little prospect of being able 
to get into our famous Dismal swamp &c. of whose fertility I 
have a still better opinion especially in M. frond. & hepat. Can 
you procure me information as to where Mr. Nuttall now resides? 
I wish much to become acquainted with him, & to propose some 
questions to him concerning the Crypto. of the Western country. 
This year I shall exert myself together with Mr. Denke in 
collecting all Phaenog &c. plants which our neighborhood contains 
in order to be able to meet the wishes of you, Mr. Cooper & Halsey 
(this latter gentleman writes me that he has sent on a parcel 
for me which however has not yet arrived). I intend to send 
you a copy of my list of Am. plants generally not yet in my 
collection—hoping that you might perhaps procure some for me, 
not growing in your vicinity, by perhaps receiving duplicates 
from others. The small list now inclosed by Right Rev. Jacob 
Van Vleck designates such of your Catalogue as he would be 
glad to procure—& on the other page I repeat to you a more 
correct list of those which I myself should be glad to receive 
from your Catalogue, together with the few American mosses 
which are wanting in my collection. I hope you will find time 
shortly to let me know how the plants I sent you answered your 
wishes—With the greatest iieii I remain Yours most Sincerely 
Lewis D v SCHWEINITZ 
P.S. Do you think Dr. Silliman could give place in his excellent 
work [American Journal of Science, 6] to a short review of the 
Musci frondos of Am? 
Musci frondosi Americani—non in Herbario LD vS. [Lists 13.] 
What is intended by the Hypn[um] cupressiforme in your Cata- 
logue? & Hypn[um] setaceum Whence is the name? 
Targionia hypophylla—among the M. hepat. is said to be in Amer- 
ica—have you met with it? 
Revised List of Phaenog. &c. plants in New York Catalogue, 
wanted by me. [Lists 124.]
