ANATOMY OF CARTILAGE. 489 



The reader is referred to works upon anatomy for a his- 

 tory of the action of the muscles. In some works upon 

 physiology, will be found descriptions of the acts of walking, 

 running, leaping, swimming, etc. ; but we have thought it 

 better to omit these subjects, rather than to enter as mi- 

 nutely as would be necessary into anatomical details, 

 and to give elaborate descriptions of movements, so simple 

 and familiar.
