In no skull is there a complete set of teeth . Most of 



the teeth, however, seem to have been lost after deaths 



except in No. 4 (which appears to be the skull of an old 

 woman), 6 and 8. 



The molars have all been erupted in every case, except in 

 No. 8, where the third molars are not developed. 



In 1 and 2, these teeth are ground smooth, but in tho 

 remainina^ skulls, where present, they do not show the 

 same signs of grinding. The bicuspids, where present, 

 show the same grinding. 



The incisors have been lost in every case. 



No. 6 has a canine which is slightly worn. 



There is no sign of caries in any of the teeth. 



CRANIAL CAPACTTY. 



Sex. No. Average. Minimum. Maximum. Class. 



Male 4 1,325 1,220 1,410 Micro-cephalic 



Female 4 1,143 1,020 1,260 n 



Total 8 1,2,34 1,020 1,410 i. 



These crania are therefore micro-cephalic. 



The average capacity of seven crania in the Museum of 

 the Royal College of Surgeons in London is 1,294, as com- 

 pared with this average of 1,234.
