26 SPHERE AND FUNDAMENTAL 



Being made .'n the spiritual image of God, he is competent to 

 rise to the conception of His plan and purpose in the works 

 of Creation. Having also a material body, like that of 

 other animals, he is also in a condition to understand the 

 mechanism of organs, and to appreciate the necessities of

 together, so as to make of them that vast picture in which 

 each animal, each plant, each group, each class, has its 

 place, and from which nothing could be removed without

 are now known to us by their fossil remains only. And 

 these are of the greatest importance, since they furnish us 

 with the means of ascertaining the changes and modifica-
