 were links in the wondrous chain of early life — evi- 

 dences of a remarkable ancestry. A volume could 

 be filled in describing the many recent discoveries 

 which naturalists of to-day consider as evidences of 

 the correctness of the deductions of Darwin. To 

 him the story of nature was plain and simple ; the 

 Giver of all things created life ; this, acted upon by 

 the natural conditions of its environment, produced 

 the varieties, which, in turn, in the long eras of time, 

 became species ; from these genera were evolved ; 

 and so the change went on, populating the world. 



The story of this evolution is told in the " Origin 

 of Species," " The Descent of Man," and other works 

 of the great naturalist, which mark epochs in the 

 history of scientific thought.
