with hard materials, that their teeth have good opportunities 

 of becoming worn. Both in the men and the women the inci- 

 sors are more worn than the molars, and of the latter the first 

 two molars are often the most worn. In the old Masaitsiak 

 the front teeth were so much worn, that the new growth of 

 dentine in the pulp took up a great part of the plane, worn 

 surface; on the molars both the cusps and the hollows were 

 worn, so that all the enamel had disappeared except along the 

 edge. According to the scale set up by ßroca for degrees of 

 wornne&s, these teeth were thus in the A^^ or extreme stage. 

 In the old woman Krulé the stumps remaining did not show 

 any greater degree of wornness than in Masaitsiak. In the 60 

 year old woman Kiajuk the front teeth were worn down a good 

 deal into the pulp ; the first molar teeth were in the 3'*^ stage, 

 as the chewing surface was just worn level; on the wisdom 

 tooth, however, the cusps were not yet worn. In the ca. 35 

 year old Samik the pulp could be seen in the front teeth, and 

 the cusps were already worn down on the molars. In the ca. 

 30 year old woman Tukuminguark the pulp was not yet bare 

 in the front teeth, and the molars had not yet been worn quite 

 level. In the scarcely 30 year old man Manigssok the pulp of 

 the front teeth could already be seen, whilst the molars were 

 perhaps a little less worn than was the case with Tukumingu- 

 ark, who was about the same age. In the 20 year old man 

 Miterk facets had just begun to appear on the front teeth, but 

 distinct facets had not yet been worn on the enamel of the 

 molars. The unmarried girl Arnanguak, who was ca. 16 years 

 old, was at exactly the same stage, whilst the ca. 18 year old, 

 married woman Akutak also had distinct facets on the molars. 

 Thus, individual differences certainly occur in the amount the 

 teeth are worn , so that it is impossible to base general rules 

 for the wear of the teeth in men and women on so few examples; 

 but I think that the above observations are sufficient to prove 

 my contention, that the teeth of the men are also greatly worn.
