Chapter III 

 SOUND BODIES 



"Do nothing unknowingly, but be taught what is requi- 

 site; and thus you will pass life the most pleasantly. Nor 

 is it meet for you to have no care for the health of the body; 

 but to make to yourself a moderation in drink and food and 

 exercise; and I call that moderation which will give no 

 pain." From the "Golden Words" of Pythagoras.
