 with the lower vertebrates and with the higher 

 vertebrates. He asks: " In what sense are the 

 Liassic Chelonia inferior to those which now 

 exist? How are the Cretaceous Ichthyosauria, 

 Plesiosauria or Pterosauria less embryonic, or 

 more differentiated species, than those of the 

 Lias?'' It is not necessary to multiply instan 

 ces. Where, then, is there evidence of Father 

 Wasmann's evolution, to "the very nature of" 

 which "it is essential to advance from what is 

 simple to what is complex'? Professor Hux 

 ley sums up by saying: 



"These examples might be almost indefinitely 

 multiplied, but surely they are sufficient to 

 prove that the only safe and unquestionable 

 testimony we can procure positive evidence 

 fails to demonstrate any sort of progressive 

 modification towards a less embryonic, or less 

 generalized, type in a great many groups of 

 animals of long-continued geological existence. 

 In these groups there is abundant evidence of 

 variation none of what is ordinarily under 

 stood as progression ; and, if the known geo 

 logical record is to be regarded as even any
