HISTORY OF ENTOMOLOGY. 473 



cessors in the progress that he has made towards ex- 

 tricating the true system. Setting out from a common 

 centre he holds on his unwearied course, endeavouring to 

 trace every set of objects that branches from it to its ex- 

 treme term. But though he studied insects analytically 

 with unrivalled success, he was not always equally happy 

 in his synthetical arrangement of them. I do not here 

 so much speak of the result which must necessarily fol- 

 low from any arrangement in a series, and which cannot 

 well be avoided ; but I allude particularly to his intire 

 adoption of the Geoffroyan system in the Coleoptera, 

 which has prevented him in many instances from seeing 

 the natural distribution of his groups. 



In 1 798, two years after the publication of Latreille's 

 first enunciation of his system, M. Clairville, a very acute 

 and learned Swiss Entomologist, drew up the following 



analytical table of insects.

Every one will think that the change of the received 

 names of the Orders, here denominated Sections, is per- 

 fectly needless. The principal merit of this system is the 

 division of insects, tacitly pointed out by Fabricius, into 



Tterophora
