32c Canadian Arctic Expedition, 1913-18 



XIV F-28 



A very small mandible. All the teeth had erupted except the third molars 

 which can just be seen within their bony crypts. The individual was thus 

 between seventeen and twenty-four years of age, and was possibly of the female 

 sex. This mandible probably belongs to the cranial remains numbered XIV 

 F-26. The muscle markings are very faint. 



The angle is slightly everted and is obtuse, measuring 121° 



(1) Intergonial width — 90 mm. 



(2) Height from the ridge between the two incisor teeth to the lower border of the symphysis 



— 29 mm. 



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



of the mandible — Right, 20-5 mm.; left, 21-5 mm. 



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



20-5X100 



Right = 70-6

(5) Thickness of the mandible measured from the inner edge of the alveolus of the second 



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

 mandible — Right, 14-5 mm.; left, 14-5 mm. 



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



the two borders — Right, 41.5 mm.; left, 43 mm. 



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



Right, 28-5 mm.; left, 29-5 mm. 



(8) Index of width of each ramus — 



28-5X100

This collection represents the skeletal remains of four individuals, two 

 adult males, an adult female and an adolescent. 



A left adult scapula. 



The shafts of two adult humeri both of the left side, exhibiting pronounced 

 muscle markings. 



A slenderly modelled let radius. 



The shaft of a right adult femur with very prominent muscle markings 



A left femur much more delicately modelled with faintly marked muscle 

 attachments. The head exhibits osteo-arthritic mischief. ' 



The diaphysis of a right femur of an individual below the age of twenty. 



The shafts of right and left adult tibiae belonging evidently to one skeleton. 



The diaphysis of the left tibia of an adolescent below the age of twenty. 



XIV F-30 



Femur, tibia and fibula of the right side. The bones are in a good state of 

 preservation, with the exception of the lower end of the femuj. They are all 

 very short and slender and exhibit faint muscle attachments. They may 

 possibly belong to the female skeleton represented in the collections F-18 and 

 F-19. The upper end of the tibia exhibits well-marked retroversion.
