CHAPTER X. 



EXPRESSION IN THE HEAD. 



Positions and movements of the head defined Flexion the only 

 symmetrical movement Action of light in causing head 

 movements ; varying effect of such stimulus in different brain 

 conditions A weak posture Effect of gravity The head 

 usually free Application of the principles of analysis to 

 head postures Movements of the jaw Physiognomy, or

IN the study of expression in the head, as in other

 and also to its movements and the postures which 

 result from those movements. 



The title of Sir Charles Bell's first essay is, " Of 

 the Permanent Form of the Head and Face, in con- 

 tradistinction to Expression." He goes on to say,* 

 "A face may be beautiful in sleep, and a statue 

 without expression may be highly beautiful; on 

 the other hand, expression may give charm to a 

 face the most ordinary. Hence it appears that our 

 inquiry divides itself into the permanent form of 

 the head and face, and the motion of the features,
