comparative study of the physiology of the vocal organs, and of ~~ 
the connection between the brain and the faculty of speech throw 
light on this problem? May not the power of speech have best 
a differentiation of the musical power, and have originated from 
the play of the intenser emotions or passions rather than from 
the mechanical movements of the arms or legs in labor?
