531. THE order of Crustacea was that of the Trilobites, those of 

 the Mollusca the Tentaculiferous Cephalopods, and the Brachio- 

 pods ; and that of the Radiata the fixed Crinoids. Two had their 

 greatest number of genera in the Jurassic period. These were 

 the Saurian reptiles and the Free Crinoids. Four had their 

 greatest number in the Cretaceous period, of which two were 

 Mollusca and two Iladiata. In five, two had their greatest 

 generic development in the Tertiary period, both being Mam- 

 malia, one Pachyclcrmata, and the other Edentata. The elephant 

 is a living example of the former, and the sloth of the latter. 



From what has been stated, it appears that of the seventy- 

 seven orders of animals, thirty-one were called into existence 

 during the Paleozoic period. These were distributed among the 

 four principal divisions of animal forms, as follows : 



Yertebrata 3 



Annulate, . . . ... 11 



Mollusca 9 



Radiate . 8

532. Thus the four principal divisions of animal forms were re- 

 presented at the first moment of creation, in a relative numerical 

 proportion not very different from that in which they still exist. 

 This result is completely incompatible with a notion which has 

 been long prevalent, that creative power manifested itself by
