THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 169 
TORREY ‘TO SCHWEINITZ 
. NEw York March 17th 1823. 
My Dear Sir 
I am ashamed to acknowledge your esteemed favour of De- 
cember last at this late day. The principal reason why I have 
delayed writing is that I expected to accompany an expedition 
which was to have set out this spring for the Rocky Mountains. 
All my time was employed in making preparations, such as packing 
my plants, , the Secy. of 
War has concluded not to send the expedition. Before writing 
about my own business, however, I will answer your letter. The 
determinations of my cryptogamic specimens delighted me much, 
as I was exceedingly anxious to receive them. I regret however 
to find so many blanks in the list. For those between Nos. 374 
& 447 I can account as I passed over a whole hundred in numbering | 
& afterwards commenced filling up the chasm—I shall continue 
filling this up till I get to 447, & then proceed regularly from 
504 where I left off. But before the No. 374 there are 52 scat- 
tered blanks, & these too, respecting specimens I was very anxious 
to hear about—Many of the blanks I believe are Jungermanniae. 
You mention some of the specimens having been destroyed by a 
broom—but that was probably not the cause of the whole loss. 
But it is useless to regret. I believe I can supply most of the de- 
ficiencies from my retained specimens—Indeed, I am confident 
that I can send you duplicates of many of them. 
I am pleased that you agree with me respecting that new 
little Botrychium. You have before this time, doubtless, seen 
Mr. Hitchcock’s description of the plant in the last No. of Silli- 
man’s Journal [30]. 
No. 374 you observe is a new species of ne am 
much pleased with this information. as I had determined the fun- 
gus to be a Sclerotium & could not find a description of the species, 
though I hardly dared to call it new. 
No. 366 you suspect to be the Targionia hypophylla—ls it 
not a Jungermannia? The plants from Prof. Dewey are certainly 
lost. The loss is as great to me as to you, as there were in the 
box a great many good things which our friend kindly intended 
for me.
