ANIMAL LIFE ASSIMILATION. 



tional connecting cells of the Cerebrum, 

 which alone has been estimated to contain 

 more than nine thousand million cells the 

 very image of infinite particularity unified 

 through association, or made universal though 

 still in a particular way or organ. The Cere- 

 brum may be deemed the creative prototype 

 of all human association, being itself so com- 

 pletely associated in its minute cellular divi- 

 sion. 



The Cerebellum is supposed to be the seat 

 of the co-ordination of the actions of the mus- 

 cles and of other organs. Many muscles have 

 to co-operate in walking for instance; then 

 again the muscular System requires respira- 

 tion for instance, which has its primal auto- 

 matic control in the Medulla. The Cerebellum 

 is composed of white and gray matter, like 

 the Cerebrum, but somewhat differently ar- 

 ranged, having not so much an originative as 

 a regulative power. An animal deprived of 

 its Cerebellum cannot make its muscles co- 

 operate to one end, although these may show 

 irregular movements. The many muscles re- 

 quired to give a sudden leap must be subordi- 

 nated for the single act: this subordination is 

 the work of the Cerebellum, which is in its 

 turn subordinated and has to obey the com- 

 manded purpose. Thus it is double, govern- 

 ing in one direction, yet being governed in an- 

 other.
