index (see Tables 9 and 10). The ascending rami are broad and 

 heavy and the coronoid processes low and stout. The extent of the 

 condylo-coronoid width gives additional leverage to the temporal 

 muscle. The surface roughenings for muscular attachment are 

 very prominent (pi. xv), the area for the insertion of the masseter 

 and pterygoid muscles being very extensive. 



The extraordinary pressure to which the jaw is subjected has 

 led to an accessory thickening in the alveolar process at the second 

 molar. This occurs in the adolescent and infantile jaws as well as 

 the adult, so it probably is an inherited trait. One of the male 

 mandibles (fig. 26) exhibits a diseased condition, which has resulted 

 in atrophy of the alveolar and coronoid processes and a shriveling 

 of one side of the jaw. The skull is similarly affected at the base and
