SUCCESSION OF ANIMALS AND PLANTS.

me to make a few more remarks upon this topic. I can, fortunately, he very 

 brief, as we possess a text-hook of Palaeontology, arranged in zoological order, in 

 whith every one may at a glance see how, throughout all the classes of the animal 

 kingdom, tiie diflerent representatives of each, in jjast ages, are distributed in the 

 successive geological formations.' From such a cursory survey, it must appear, that 

 Avhile certain types prevail during some periods, they are entirely foreign to others. 

 This limitation is conspicuous, -with reference to entire classes among Yertebrata, 

 ■while, in other types, it relates more to the orders, or to the families, and extends 

 frequently only to the genera or the sjiecies. But, whatever be the extent of 

 their range in time, we shall see presently, that all these types bear, as far as 

 the order of their succession is concerned, the closest relation to the relative rank 

 of living animals of the same types compared with one another, to the phases of 

 the embryonic growth of these types in the present day, and even to their geo- 

 graphical distribution upon the present surface of our globe. I will, however, select
