30. Review of the age of Reptiles. — From this 

 examination of the organic remains of the Secondary For- 

 mations we obtain the following results : — that the seas, 

 lakes, and rivers, during these geological epochs, swarmed 

 with reptiles, fishes, mollusca, Crustacea, radiaria, poly- 

 paria, and other zoophytes ; all of extinct species, and

On the land we find no analogy to the terrestrial inha-
