I have before expressed my sentiments upon several 

 of these Orders a : I shall not here repeat them, but shall 

 merely observe, with respect to those I have not adopted, 

 that, though perhaps not entitled to rank as Ord'rs, 

 most of them form natural groups. His Orders, however, 

 of Arachnida must be excepted from this remark, since 

 they are evidently artificial. His analyses of his Orders, 

 though in general they give natural groups, are usually 

 not carried so far as those of M. Latreille, so as seldom 

 to indicate what may properly be denominated families. 

 He has made his nomenclature for his so-called families 



a See above, pp. 378, 380, 385, 390.
