THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 175 
At the same time let me know, if you are in possession of 
Hedwig’s Species Muscorum Frondosorum, Opus Posthum. a Frd. 
Schwagrichen editum in quarto with 72 Plates [z9]—I have 
chance of procuring it here for the very cheap price of 10 Dollars 
(at least I think it cheap) & perhaps might get it for 8$. If you, 
or any of your friends would wish to have it I will get it, and send 
it on. 
Forgive me for troubling you at such length & if you can with- 
out inconvenience let me soon hear from you. 
I remain with sincere regard 
Your most obdt Servt 
Lewis D v SCHWEINITZ 
P.S. I am preparing to go largely:into the Fungi this year & 
possibly reattempt the Algae aquat. 
TORREY TO SCHWEINITZ 
l NEw YORK, April 11th, 1823. 
My Dear Sir, 
I received a few days since your very acceptable letter of 
the 2nd inst. There is indeed no probability that an expedi- 
tion will be sent to the Rocky Mountains this season & I have re- 
solved to make myself contented here. It will be in the highest 
degree agreeable to me to see you in New York should you make a 
visit in this quarter, but you will doubtless be much disappointed 
in finding anything worth your notice among us. After being in 
Philadelphia, New York will appear to great disadvantage. You 
will, however, see our good friend Mr. Halsey, who beside myself, is 
the only botanist here! If you are fond of Mineralogy there are 
many collections among us that you would perhaps be pleased to 
see. Whether it will be in my power to make a visit to Bethlehem 
this season, will depend on my not being engaged in more im- 
portant avocations in July & August next, which was the time I 
had appointed to spend a few weeks in traveling. At any rate, 
while I am engaged in Botany you may depend I shall never forget 
a friend whose acquaintance has offered me so much pleasure as 
yourse'f. 
By a friend who goes to Philadelphia in a day or two, I 
shall send, to the care of J. & A. Ritter of Phila. a small package
