XIY H-7 



The mandible belongs to Cranium XIV H-5, and is therefore that of a young 

 adult female. All the teeth had erupted but already exhibit moderate wear. 

 The angle is obtuse, 129°, and is everted. The grooves for the lingual nerves 

 upon the inner aspect immediately below the third molar teeth are well marked. 

 The genial tubercles and the other muscle markings are pronounced. 



MEASUREMENTS 



(1) Intergonial width — 101-3 mm. 



(2) Height from the ridge between the central incisor teeth to the lower lorder of the sym- 



physis — 37-0 mm. 



(3) Height from the inner edge of the alveolus of the third molar tooth to the lower border 



of the mandible — Right, 30 mm.; left, 30 mm.
