Explanation of Plate 1. 
Section through the left Glenoid hossa of a European. 
C *= Condyle of lower jaw. 
E = Eminentia articularis. 
F = Glaserian fissure. 
G = Anterior concave portion of glenoid fossa. 
P = Petrous portion of temporal bone. 
S = Squamous portion of temporal bone. 
The above section was cut in the sagittal plane a little to the left of the 
deepest part of the Glaserian fissure. It will explain the diagrams drawn 
from the sections of the casts of various Glenoid Fossae shown in figure 2, 
as it illustrates the relations of the parts of the skull at that point. The 
lines EGF in Plate II correspond in position in the skull to the line EGF 
in Plate I. In these diagrams the fossa has been drawn in its natural position, 
i.e. with the skull placed upright. In order to recognize the term ‘concave 
as applied to this fossa in its anatomical description, and the height of the 
eminentia articularis, it is only necessary- to turn the diagrams upside down.
