The massively modelled mandible, of an adult male most probably. The 

 various muscle markings are very pronounced. The angles and the lower halves 

 of the rami are strongly everted, giving the mandible a remarkable appearance. 

 The grooves for the lingual nerves are well exhibited. The molars and the 

 second left premolar are still present, but all the remaining teeth had been in 

 existence at death. The teeth show very little wear while the cusps of the third 

 molars are practically intact. The jaw therefore belonged to a young adult. 

 The angle is obtuse, measuring 126°. 



MEASUREMENTS 



(1) Intergonial width — 125 mm. 



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



S3rmphysis — 35-5 mm. 



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



border of the mandible — 32 mm. 



(4) Index of height of the molar region of the mandible — 



32X100 



=90-1 



35-3 



(5) Thickness of the 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, 17 mm.; left side, 16-5 mm.
