1. Zoology of the Chalk. — The examination of the 

 Cretaceous and Wealden formations has afforded an in- 

 structive exposition, not only of the nature of oceanic 

 and river deposits in general, but also of the condition of 

 animated nature at the close of the geological cycle which 

 comprises the secondary epochs. It will therefore be 

 expedient in this stage of our inquiry to consider the 

 general features of the animal kingdom during the periods 

 embraced in this review.
