196 PHYSICAL EXPRESSION. 



hence the necessity, in analyzing a facial expression, 

 to observe whether it be symmetrical. 



An expression may affect the face principally in 

 the upper, middle, or lower portions, and it may 

 appear more on one side than on the other ; hence, in 

 analyzing a face, each half and each region must be 

 examined separately. I have found the following 

 method convenient for making an analysis. 



To examine a face, hold a sheet of paper in front of 

 it, with one edge vertical, and opposite the middle of 

 the face ; either half of the face can then be covered 

 in turn while the other half is examined. Again, 

 the face may be divided into three zones, or 

 horizontal areas, the upper, middle, and lower. To 

 observe each zone in turn, hold the sheet of paper 

 with one margin horizontal, leaving the forehead 

 above the eyebrows uncovered, this shows the 

 upper zone ; then view only that part of the face 

 which is below the lower margin of the orbits, 

 showing the mouth, the greater part of the cheeks, 

 and the openings of the nose, this is the lower zone ; 

 lastly, the middle zone may be demonstrated alone 

 by holding the horizontal margin of one sheet of 

 paper so as to cover all above the eyebrows, and 

 another sheet of paper so as to cover all below the 

 orbits, thus leaving to view the eyebrows, the eye- 

 lids, and eyeballs, with the bridge of the nose. 



By these methods we can easily examine for 

 symmetry in a face, both as regards form and 

 action ; and we can, at the same time, also observe 

 any special nerve-muscular conditions in any 

 particular zone.
