RECAPITULATION. 201 



limited to particular geographical areas, and the various 

 combinations of these types into zoological provinces of 

 unequal extent, exhibit thought, a close control over the 

 distribution of the earth's surface among its inhabitants. 



10th. The identity of structure of these types, notwith- 

 standing their wide geographical distribution, exhibits 

 thought ; that deep thought, which, the more it is scru- 

 tinized, seems the less capable of being exhausted, though 

 its meaning at the surface appears at once plain and in- 

 telligible to every one. 



llth. The community of structure, in certain respects, 

 of animals otherwise entirely different, but living within 

 the same geographical area, exhibits thought, and more 

 particularly the power of adapting most diversified types 

 with peculiar structures to either identical or to different 

 conditions of existence. 



12th. The connection, by series, of special structures 

 observed in animals widely scattered over the surface of 

 the globe, exhibits thought, unlimited comprehension, and 

 more directly omnipresence of mind, and also prescience, 

 as far as such series extend through a succession of geo- 

 logical ages. 



13th. The relation there is between the size of animals 

 and their structure and form, exhibits thought ; it shows 

 that in nature the quantitative differences are as fixedly 

 determined as the qualitative ones. 



1 4th. The independence, in the size of animals, of the 

 mediums in which they live, exhibits thought, in establish- 

 ing such close connection between elements so influential 

 in themselves and organized beings so little affected by 

 the nature of these elements. 



15th. The permanence of specific peculiarities under 

 every variety of external influences, during each geological
