24c Canadian Arctic Expedition, 1913-18 



XIV r-17 



The bones of this cranium are so comminuted that it is impossible to carry 

 out a reconstruction. The facial portion, however, is sufficiently preserved to 

 make one decide that it had belonged to a young adult female. The sutures are 

 still very distinct, but the teeth exhibit a considerable degree of wear, though 

 there is no caries. 



The mandible had belonged to this skull, as the two dental arches articulate 

 perfectly. It is small and slimly built. The left condyle had been gnawed away. 

 The left angle is slightly damaged. All the molar teeth, the second right pre- 

 molar and the right canine are present. The other teeth had been in existence 

 at death as their alveoli are normal. The angle of the jaw is strongly everted, 

 and measures 126°. 



MEASUREMENTS 



(1) Intergonial width (approximate) — 102 -5 mm. ' 



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



sjTuphysis — 37 -5 mm. 



(3) Distance from the innder border of the alveolus of the last molar tooth to the lower 



border of the mandible — Right side, 28 mm.; left side, 27-5 mm. 



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



28X100 



Right = 74-6 



37-5 



27-5X100 



Left — = 73-3 



37-5 



(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, 

 16-5 mm.; left side, 16 mm. 



(6) Height of each ramus, measured from the bottom of the sigmoid notch — Right, 51 mm. ; 



I'eft, 50.5 mm. 



(7) Width of the rami measured at right angles to their borders — Right, 37-5 mm.; left, 



36-5 mm. 



(8) Index of width of each ramus — ■ 



37-5X100 



Right = 73-5

Left = 72-2

The two broken limb bones are the shafts of the right and left humeri 

 belonging to one adult skeleton. The articular ends had been gnawed by wild 

 animals. The muscular attachments are well marked.

The slightly weathered skull of a young adult female. The teeth had all 

 erupted but the alveoU for the third molars are still very small. All the sutures 

 are very distinct.
