Size of the head, as expressed by the mean diameter of the head, or cephalic module, by 



stature groups — Continued 



Growth of the face. — The measurement of the face was restricted to 

 its two principal dimensions, namely, height and maximum breadth. 

 The height, measured with the compass d'epaisseur (Mathieu), is 

 the distance from the lowest point of the chin in the median line, 

 the compass being applied with some firmness, to a point corre- 

 sponding to the nasion. The location of this point is not difficult to 

 determine with fair accuracy if the investigator has a working 

 acquaintance with the location of the naso-frontal suture in chil- 

 dren's as well as in adults' skuUs."^ 



The breadth is the maximum bizygomatic diameter, measured also 

 with the compass d'epaisseur. This measurement offers no special 

 difficulty in subjects of any age. 



The data obtained are arrangred in the succeeding form: 



Growth of face, by stature groups 



a The writer prefers the nasion point as the superior tenninus of the facial height measurement to 

 either the obelion or crinion (hair hne). The former is always uncertain and the latter is particularly 

 difficult to determine in the younger children, in some of whom much of the forehead is covered by a 

 rather long hair-like down.
