HISTORY OF ENTOMOLOGY. 461 
the exception of some of his sections, merit the same 
character. Indeed, he has left far behind all his prede- 
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 serzes, and which cannot 
well be avoided; but I allude particularly to his adop- 
tion of the Geoffroyan system in the Coleoptera, which 
has prevented him in many instances from seeing the 
natural distribution of his groups. 
In 1798, 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.
