THE DOCILE MAMMALS. 271 



in the diversity of their uses, and hare also observed the 

 adaptation of certain organs to special purposes fitting dif- 

 ferent •beings for special stations in life. We have seen 

 that there is a balance of power between the vegetable- 

 feeding animals and those which prey upon them, and that 

 there is a harmony in nature between animals and their 

 surroundings. Throughout our studies we have seen that 

 in the higher animals, especially the vertebrate forms, the 

 brain has increased in size and complexity, accompanied on 

 the whole by an increase in intelligence, until it reaches 

 its highest development in man, who is fitted to become 

 the historian of creation, and by observation and reflection 

 on external nature to rise to the conception of a God of 

 nature, by whose infinite and all-pervading intelligence all 

 things, material and immaterial, have been created by pro- 

 cesses which man can in a measure trace. The study of 

 animated nature, then, is glorious in its results, while 

 disciplining and developing man's intellectual and moral 

 powers.
