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 -f , the vertebrated ; 

 and M.LatreilleJ, the class ofAnnulosa 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 Linnaeus, 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,
