RECAPITULATION. 203 



how wide a cycle of modulations may be included in the 

 same conception, without yet departing from a norm ex- 

 pressed more directly in other combinations. 



21st. The order of succession of the different types of 

 animals and plants characteristic of the different geo- 

 logical epochs, exhibits thought. It shows, that, while 

 the material world is identical in itself in all ages, ever 

 different types of organized beings are called into exist- 

 ence in successive periods. 



22d. The localization of some types of animals upon 

 the same points of the surface of the globe, during several 

 successive geological periods, exhibits thought, consecutive 

 thought ; the operations of a mind acting in conformity 

 with a plan laid out beforehand, and sustained for a long 

 period. 



23d. The limitation of closely allied species to different 

 geological periods, exhibits thought ; it exhibits the power 

 of sustaining nice distinctions, notwithstanding the inter- 

 position of great disturbances by physical revolutions. 



24th. The parallelism between the order of succession 

 of animals and plants in geological times and the grada- 

 tion among their living representatives, exhibit thought ; 

 consecutive thought, superintending the whole develop- 

 ment of nature from beginning to end, and disclosing 

 throughout a gradual progress, ending with the introduc- 

 tion of man at the head of the animal creation. 



25th. The parallelism between the order of succession 

 of animals in geological times and the changes their living 

 representatives undergo during their embryological growth^ 

 exhibit thought ; the repetition of the same train of 

 thoughts in the phases of growth of living animals and 

 the successive appearance of their representatives in 

 past ages.
