and Writ ings of Dr Olaus Swartz. 23 
i. 2. 24.), Cinclidium (Schrad. Journ, 1801, i. 25.), Calym- 
peres, lastly, which Weber published in his Tabula Muscorum, 
Kilon, 1813. 
It is to Swartz, especially, that we owe a more intimate and 
solid knowledge of the Ferns. When he returned from his 
great journey, he illustrated the genus Vittaria , confiding in the 
observations of Smith (Neue Schriften der Berk Gesellsch. Na- 
turf. Ereunde, ii. 129.) He elaborated a new systematic ar- 
rangement of this family (Schrad. Journ. 1800 ii., 1801 ii. 
273.), in which, besides innumerable new species, he first pub- 
lished the genera Lygodium , Psilotum , Botrychium , and Gram - 
mitis. His Synopsis Filicum, published at Kilon, in 1806, is 
deservedly admired, on account of its very accurate characters 
of nearly eight hundred species, its beautiful descriptions and 
excellent figures. In this work he gave to the world the new 
genera Anemia , Mohria , and Cheilanthes . Lastly, he increased 
his reputation by the Brasilian Ferns , collected by Freigreiss , 
(Vetensk. Acad. Handl. 1817, p. 53.) 
Nor was he deficient in the knowledge of Lichens , or even 
Fungi. Of the former, he described many in the Flora India 
Occidentalism and Fasciculus Lichenum Americanorum 9 Erlang. 
1811 ; and, of the latter, chiefly the indigenous species, in the 
Transactions of the Stockholm Academy (Vetensk. Acad. 
Handl. 1808, 1809, 1810, 1811, 1812, 1815); and kidded also 
the new genus Verpa (ib. 1815, 129.) 
Although less partial to Zoology than botany, he did not, how- 
ever, entirely neglect this study. He illustrated the History of 
Myxine (Vetensk. Acad. Handl. 1790, p. 114.), of the White 
Termite (ib. 1792, p. 228.), of the Medusa (ib. 1788, p. 198., 
1791, p. 188.), of the Pulex penetrans (ib. 1788, p. 40.), and 
of Copicerus , a new genus of insects (ib. 1802, p. 270.), and 
inserted several new species of insects in the Synonymia Insec- 
torum of Schonher, p. 2. and 3. Besides, he added descriptions 
of animals to the figures published by Palrnsbruch and Billberg 
(Svensk Zoologi.) 
Although, by these works, Swartz has evinced himself a dili- 
gent observer of nature, and especially a most learned and most 
sagacious botanist ; yet he was very fond of those arts which re- 
duced science to practice, and are conducive to public arid domes-
