generation was essentially that of Linnaeus ; hence he judged 

 of the Cryptogams according to the scheme of the Phanero- 

 gams, and, not perceiving their peculiarities, he virtually 

 characterised them by negative marks. 



If we notice in the above table how the Phanerogams are 

 separated into classes, it strikes us that the triple division into 

 hypogynous, perigynous, and epigynous is repeated no less 

 than four times ; this shows that Jussieu had mistaken ideas of 

 the value of these marks for classification, whereas the recur- 

 rence of them so often should of itself have suggested a doubt 

 on this point. To judge of his system more exactly we must 

 here give his series of the families, which he had already raised 

 to the number of a hundred.
