NEXT STEP IN EVOLUTION 



Nature is not divided. What 

 means the hereditary likeness, 

 mental and spiritual — not less 

 marked than the physical ? These 

 marks often skip many generations 

 and then reappear again in full. 

 They can not, therefore, be the 

 result of education or imitation. 

 Nor is it easy to believe that they 

 were placed within us by a direct 

 act of creation, as the old-fash- 

 ioned theological professor taught 

 that God mixed the fossils with 

 the plastic stones at creation, 

 somewhat as a cook mixes raisins 

 and other fruits in the dough for 

 her plum-pudding. 



What means the gradual devel- 

 opment in the brain of the cere- 

 brum and cereballum, the organs 

 of the soul powers, enlarging from 

 generation to generation? These 

 are scarcely visible in the lowest 

 animals. They become larger as 

 we advance up the animal scale
