RISE AND PROGRESS OF ZOOLOGY. 83 
proceeded to other and much more numerous com- 
binations and divisions. This school was founded 
by three eminent men, all of whom have disappeared 
from the ranks of science within the last two years. 
M. Lamarck* undertook the investigation of the 
invertebrated animals; M. Cuvier+, the vertebrated; 
and M. Latreille{, the class of Annulosa or of Insects. 
The systems respectively invented by these able 
zoologists will be examined in some detail during 
the course of this publication, and it will therefore 
be unnecessary, in this place, to investigate their 
merits. We have also come to that era of the 
science, whereof many of the chief actors are now 
living; and whose works cannot, with propriety, be 
spoken of with that freedom (and, we hope, with 
that impartiality ) we have hitherto done, and which 
is expected from the historian of times that are past. 
We shall, therefore, merely state the chief charac- 
teristics of that school which succeeded, in France, 
to that of Buffon, and briefly enumerate the leading 
works which it has produced. 
(37.) It may naturally be supposed, that since the 
time of Linnzeus, our knowledge of nature had been 
vastly extended ; so that the species had been more 
than quadrupled. Hence arose the necessity of 
instituting a proportionate number of new genera,
