‘THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 125 
& try to make drawings of such as appear new) & at the beginning 
of this year I have commenced an augmentation in such a manner, 
that I have 5 parallel collections as complete as I can obtain speci- 
mens in order to send to friends who wish to have them. Please 
therefore to let me know what species you have firmly established 
& I shall send you specimens of all the rest of mine of which I 
have any—for I don’t like to send such as you are already suffi- 
ciently acquainted with, as these may be wanted by some other 
friend. My catalogue of Fungi, together with descriptions of 
| all the new species by me established & specimens of them, I 
took with me to Europe òn my visit there in the year 1817-18 & 
left them in the care of Dr. Schwagrichen at Lipzic to make use 
of them at his discretion [75]. Since my return, having provided 
myself with instruments & books I have pretty zealously turned my 
attention to the Musci, Jungerman|[niae] & Lichens & sweet water 
Algae, & have succeeded in determining a considerable number. 
Especially Lichens & Musci hepatlici] we are richin. I have found 
above 300 species of the former, & about 50-60 of the latter. Of 
all these (or at least of most of them) I have duplicates & am con- 
tinuing their collection, so that you can get them as soon as ar- 
ranged & separated which however cannot be done on account of 
my avocations of duty before the end of next winter. What has 
been of great service to me was the happy circumstance that I 
succeeded in procuring from Dr. Schwagrichen & other botanists 
of Germany specimens of the greater part of the German musci, 
hepat., Lichens, & all their [sweet] water algae—by which I am 
greatly aided in determining our plants. In the mean time I 
have not neglected the Phaenogamic plants. My German 
friends liberally furnished me with the greater part of those 
growing on the continent & I have added a considerable number 
of the American ones, so that my Herbar[ium] which I have 
arranged handsomely & convenient, now contains, includ[ing] 
Cryptog[amia], near 6000 plants altogether from their native soil 
either of Germany & England, or America. Lately I have con- 
ceived some idea of preparing an English & Latin work on 
the Cryptogamia of the United States or of North America 
generally & you can therefore judge how much I wish that bo- 
tanical Friends like yourself would aid me by communicating
