02 Measf(re)}W)its of One Hundred and Thirti/ Criminals 
"Facial Symmetry" is not a measurement but is judged by carrying the steel 
tape from the External Occipital Protuberance forward to the middle point of the 
Chin and noticing which side is greater. 
" Nasal Deflection " is judged in a similar manner. 
The Curve of the Forehead is taken :— the limbs of the callipers are fixed 
at 10 cm. apart, and one limb placed on the Nasion and the other on the Vertex in 
the middle line. The curve between these two points is measured with the tape 
and is the Forehead Curve. 
The Auricular-Alveolar, Auricular-Nasal, Auricular-Occipital, and Auricular- 
Mental Diameters are taken with the callipers, and are the distances between the 
Middle of the External Auditory Meatus and the Alveolar Point, the Nasion, the 
External Occipital Protuberance, and the Chin respectively. 
The Chin and Occipital Projections are taken by placing the standard behind 
the subject with the horizontal arm pointing forward. A weighted tape is hung 
from the horizontal arm and hangs plumb, just touching the External Occipital 
Protuberance or Chin ; and the distance taken by callipers between the External 
Auditory Meatus and a steel bar at right angles to this plumb-line is the 
Projection required. 
The head measurements are all expressed in millimetres. 
The Horizontal Circumference is divided into four segments to facilitate the 
comparison of the Anterior and Posterior and Right and Left Segments. 
The following terms and abbreviations are used in describing the shape of the 
Nose : — 
Rect. = Rectilinear, Concave, Convex, Hump, Und. = Undulating, refer to 
shape from Nasion to tip ; Hor. = Horizontal, Elev. = Elevated, Desc. = Descending, 
refer to angle from tip to junction with upper lip. 
The present investigations have been made on 100 " Ordinary " and 80 Lunatic 
Criminals.
