768 Historical Sketch of the Science of Botany |December, 
Americe Septentrionalis Cryptogamicz,” containing the liver- 
worts, and 1825, a Monograph of the genus Carex. He col- 
lected the fungi of Carolina, a catalogue of which, containing 
1373 species, was published by Schwaegrichen, the well known 
cryptogamist, in Leipzig, 1822. 
The catalogue of plants collected in the North-western terri- 
tory during Major Long’s second expedition, is written by 
Schweinitz. This expedition was described by Wm. H. Keating, 
the geologist of the party, and published in London in 1825, in 
two volumes, entitled, “ Narrative of an Expedition to the Source 
of St. Peter’s river, Lake Winnepeek, Lake of the Woods, etc., 
performed in the year 1823.” The party left Philadelphia on the 
30th of April, and the route of the expedition was the following: 
Wheeling, Fort Wayne, Chicago, Fort Crawford, Fort St. Aa- 
thony, up the St. Peter’s river to its source, down the Red 
river to Lake Winnipeg, Rainy lake, Fort Williams on Lake 
Superior and return on the lakes. Edwin James was appointed 
botanist, but he missed the place of meeting, so Mr. Thomas Say, © 
the zoologist of the expedition, undertook to collect the plants. 
As several boxes containing collections, and dispatched during 
the expedition, were lost, the botanical collection was very poor, 
only 130 species. As poor as the collection was, the description 
of the species called new by Schweinitz, are mostly riddles not 
yet solved. So the expedition, otherwise interesting, was unim- 
portant as to botany. 
Dr. Douglass Houghton, who met, in 1845, a sad end by 
drowning in Lake Superior, was a member of Schoolcraft’s Ex- 
pedition to the sources of the Mississippi river in 1832, the nar- 
rative of which was published in 1855. He collected about 250 
species of plants, only a few of which were new. 
Up to this time a number of botanists were at work on the 
Pacific coast. 
Adelbert Chamisso de Boncourt (1781-1838) and Frederik 
Eschscholtz (1793-1831) were commissioned by the Russian 
government, the one as naturalist, the other as physician, to 
the Russian Exploring Expedition in the Pacific and Behring 
straits, under the command of Kotzebue, 1815-1818, and explored
