 their pupils. Therefore, he who has much labor to per-

PRACTICAL INFERENCES FROM THE FOREGOING PRINCI- 

 PLES. 



Connection between the Brain and the Muscles. The 

 intimate connection which exists between the muscles 

 and the brain between the nervous system generally, 

 and those parts by which the motions of the human 

 frame are produced, and which connection has been 

 illustrated by a reference to the voluntary muscles, indi- 

 cate, in a most decided manner the mutual dependence 

 which subsists between them ; and tend to show as 

 clearly as the nature of the case will admit, the necessi- 

 ty of employing both the nervous and muscular func- 

 tions at the same time, in order that both should be in a 

 healthy state. And especially do these principles show, 

 that the nervous system cannot long be employed alone 

 without a derangement in the functions of both. 



It has been our chief object in the foregoing sections, 

 to show the connection which exists between the ner- 

 vous system and the voluntary muscles, but this may be 

 taken as an example of the existence of the same rela- 

 tion between that system and all the muscular fibres in
