 animals and plants, but doing violence to the 

 natural arrangement of those organisms. 



To do justice, however, to the discernment of 

 Linnaeus, it should be added that he was fully aware 

 of the artificial nature of his classification. A real 

 natural system, founded on the true affinities of 

 animals and plants as indicated by their structural 

 characters, he regarded as the highest ami of classifi- 

 cation. But, he never completed a natural system, 

 learning only a fragment. 



Even the larger groups of animals were extended
