Eskimo Osteology c33 



XIV r-31 



This group represents the skeletal remains of one individual. 



The skull is that of a young adult female. There is still a large area of 

 scalp bearing long black hair adherent to the occipital region. The sutures are 

 very distend. There is osseous union between the basi-occipital and the sphen- 

 oid, thus placing the age over 25. All the teeth of the upper jaw had erupted. 



The mandible is small. All the teeth had erupted except the third left 

 molar; the first left molar had apparently never developed at all and the second 

 is in consequence strongly tilted forwards. The angle is strongly everted and 

 registers 125°. 



MEASUREMENTS 



(1) Intergonial width — 114-5 mm. 



(2) Distance from the ridge between the central incisors to the lower border of the symphysis 



— 32 mm. 



(3) Distance from the inner edge of the alveolar border of the mandible opposite the site 



of the third molar teeth to the lower border of the mandible — Right, 28-5 mm.; left, 

 29-25 nmi. 



(4) Index of height of molar region of jaw — 



28-5X100 



Right =89-06

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



tooth to the point opposite this externally, where the anterior border of the ramus 

 joins the body — Right, 18-25 mm.; left, 17-5 mm. 



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



the borders — Right, 52 mm.; left, 53 mm. 



(7) Width of each ramus, measured at right angles to its borders — Right, 37-5 mm.; left, 



36-5 mm.

The other bones are: — 



The atlas and a typical cervical vertebra. One typical rib, scapula, humerus 

 second and third metacapals, astragalus, second and fifth metatarsals, all of the 

 right side. One typical rib, internal cuneiform and the proximal phalanges of 

 the great toe, all of the right side. 



The cranium is that of a young adult female with black hair still adherent 

 over the occiput. The skull is badly holed.
