214 PHYSICAL EXPRESSION. 



CHAPTER XII. 



EXPRESSION IN THE EYES. 



The eyeballs : their position and the mechanism for their move- 

 ment Iris, a muscular apparatus; its nerve supply The 

 pupil contracted by light, and accommodation for near vision ; 

 its reflex dilatation, and its variation in conditions of emotion 

 and on brain stimulation Mechanism of the eyelids Im- 

 portance of distinguishing expression by the eye and the parts 

 around Movements of the eyes Loss of associated move- 

 ments of eyes under chloroform, and in deep sleep Movements 

 of eyes from brain stimulation Horizontal movements most 

 common Attraction and repulsion of the eyes by sight of an 

 object Spontaneous movements Eyes free or disengaged 

 Mental states expressed by attraction or repulsion of the eyes 

 Horizontal and vertical movements contrasted Intel- 

 lectuality of upward movements. 



MOST people, if questioned, would say that in the 

 human face there is great expression in the eyes ; 

 that the eyes are very expressive features, and that 

 the soul and mind shine out in the eyes, etc. In 

 conversational language, which is not always quite 

 precise, the term " eye," as a feature of the face, is 

 used somewhat loosely ; but it is necessary in this 

 method of study to differentiate carefully between 

 expression seen in the eyeball, and expression in the 

 parts that surround the eyeball the eyelids, the 

 eyebrow, etc.
