THE DAWN MAN OF PILTDOWN 



195 



6 — More direct evidence that the lower 

 jaw in spite of its apelike features is really 

 that of a human being is furnished by 

 the measurements 

 given by Dr. Smith 

 Woodward {op. cit., 

 p. 130). These 

 measurements are 

 on the whole nearer 

 to those obtained 

 from early human 

 jaws than to those 

 of full-grown apes. 



7 — The lower mo- 

 lars approach those 

 of apes in their rela- 

 tive narrowness and 

 in the large size of 

 the third lower mo- 

 lar (as indicated by 

 its alveolus), but in 

 their flattened worn 

 surfaces with very 

 thick enamel they 

 recall human rather 

 than simian teeth. 



8 — The condyles, 

 or articular surfaces, 

 of the Piltdown jaw 

 as compared with 

 those of the great 

 apes were more slen- 

 der, less expanded 

 transversely, and 

 supported by more 

 slender pillars of 

 bone. In this fea- 

 ture the Piltdown 

 jaw is more like the 

 average human type, 

 and this fact tends 

 to remove the sup-, 

 posed difficulty in 

 fitting this, in many 

 ways apelike jaw on 

 to a human glenoid, 

 or upper jaw socket. 



9 — Doubts have also been expressed 

 as to the association of the remarkably 

 apelike canine with the other Piltdown
