The adult male mandible exhibits marked wearing of the few teeth that 

 remain. The third left molar had never developed. The second right premolar 

 had been lost during life as its alveolus is obliterated. All the other teeth had 

 been present at death, as their alveoli are deep and healthy. The jaw is massive, 

 and the muscular markings are pronounced. 



The angle is obtuse, measuring 129°. The groove for the lingual nerve is 

 strongly marked on both sides. 



MEASUREMENTS 



(1) Intergonial width — 117 mm. 



(2) The distance from the ridge between the central incisor teeth to the lower border of the 



symphysis is remarkable— 47 mm. 

 •(3) Distance from the inner border of the alveolus of the third molar tooth to the lower 

 border of the mandible (right side only) — 32 - 5 mm. 



(4) Index of height of the molar region of the mandible (right side only) — 



32-5X100 



= 69-1

(5) Thickness of mandible, measured from the inner border of the alveolus of the third 



molar tooth to the point where the anterior border of the ramus joins the body (right 

 side only) — 18-25 mm. 



(6) Height of each ramus, measured from the bottom of the sigmoid notch, and parallel to 



the anterior and posterior borders — -53-5 mm. 



(7) Width of each ramus, measured at right angles to the anterior and posterior borders — 



Right, 45 mm.; left, 47-5 mm.
