Pe ADVERTISE MENT. 
wt AP PAE, EC : 

Tur following work having superseded in Germany 
all other Introductions to Botany, of the longest 
standing and greatest reputation, it occurred to the 
present Editors that a translation of it would be a ~ 
very acceptable present to the lovers of natural 
science in this country. They do not here intend. 
to draw a comparison between this and the elemen- 
tary treatises on Botany in our own language; but 
it may be allowable to say that it contains many 
things which are not to be found in any of them ; 
particularly an explanation of the phenomena of Ve- 
eetable Physiology, on the principles of the latest 
discoveries in chemistry. ‘There are also added sec- 
tions on the Diseases of Plants, a History of the 
Science, and an account of Botanical Writers. ‘The 
Plates illustrate every botanical term; and the table 
of Colours, which is altogether new, will be of es- 
sential use to students, not of Botany only, but also 
of Natural History in general.
