 could not but shrink from encountering." 



728. About two months is considered the average time 

 necessary to fit a man for the ring, or for public exhibi- 

 tion as a boxer by the above means ; and it is particularly 

 worthy of observation, that alcoholic liquors are discarded

 powers and deotroy the courage of their pupils. Therefore, 

 he who has much labor to perform, or a battle to fight,

PRACTICAL INFERENCES FROM THE FOREGOING PRINCIPLES. 



729. Connexion between the Brain and the Muscles. The 

 intimate connexion which exists between the muscles and 

 the brain between the nervous system generally, and 

 those parts by w T hich the motions of the human frame are 

 produced, and which connexion has been illustrated by a 

 reference to the voluntary muscles indicate in a most de- 

 cided manner the mutual dependance which subsists be- 

 tween them ; and tend to show as clearly as the nature of 

 the case will admit, the necessity of employing both the 

 nervous and muscular functions at the same time, in order 

 that both should be in a healthy state. And especially do

730. It has been our chief object in the foregoing sec- 

 tions, to show the connexion which exists between the 

 nervous system and the voluntary muscles, but this may be 

 taken as an example of the existence of the same relation 

 between that system and all the muscular fibres in the
