 have held the same opinion. 



But though I feel convinced, as far as 

 my experience goes, that genera are really 

 founded in nature, I am far from asserting 

 that Linnseus, or any other writer, has suc- 

 ceeded in fixing all their just limits. This 

 deep and important branch of natural science 

 reo x uires the union of various talents. Many 

 persons who can perceive a genus cannot de- 

 fine it ; nor do acuteness of perception, so- 

 lidity of judgment, and perspicuity of ex- 

 pression, always meet in the same person.

 which should separate the species of a good 

 genus, would by that very test alone, prove 

 entirely worthless ; and if such a defect be 

 sometimes unavoidable in an artificial one, 

 contrivances must be adopted to remedy it,
