618 HUMAN JAW AND FLINT-IMPLEMENTS 



To summarize the result of the intrinsic evidence in the 

 view here taken. 



1. The suspected haches showed the characters which are 

 found in modern fabrications, and they were wanting in all 

 those which stamp haches of unquestionable antiquity. 



2. The human jaw exhibited the physical characters 

 which belong to ancient bones of the modern period, and it was 

 wanting in those commonly seen in Quaternary fossil bones 

 of undoubted antiquity occurring under analogous conditions. 



One part of the case which was entered for inquiry upon 

 the programme forwarded from London before the meeting of 

 the Conference, was not gone into at all, viz. the anatomical 

 character of the jaw, as significant of race-distinction. The 

 issue was narrowed to fossil, or non-fossil ; and on the present 

 occasion I shall not cumber this communication by any 

 remarks on the subject, although fully impressed with its 

 importance. 



[The precise measurements of the jaw were as follows : 1 



Dimensions of Fossil Lower Jaw (Moulin-Quignon) Inches 



1. Extreme length of ramus from chin to poster, edge of condyle by 



callipers ........... 5 - 



2. Length of horizontal ramus from anterior marg. coronoid to incisive 



border 2-6 



3. Height of ascending ramus to apex of coronoid .... 2 - 2 



4. Height of sigmoid notch measured parallel to posterior border along 



middle of ascending ramus . . . . . . . . 1"9 



5. Width of ascending ramus at constriction . . . . . 1'4 



6. Antero-post. extent of sigmoid notch (from edge of condyle to ditto 



coronoid) ........... 13 



7. Height of sigmoid notch ........ 0'53 



8. Height of jaw at incisive border ....... 1-13 



9. Ditto at middle exact where antepenult, alveol. filled up . . 1*2 



10. Ditto behind last molar alveolus ....... 1-2 



11. Transverse diameter of condyle ....... 078 



12. Antero-posterior of condyle ........ 0'4 1 



B. Extrinsic Evidence. — The counterfeit characters of the 

 Moulin-Quignon haches of the 'black seam,' insisted upon 

 by the English members of the Conference, were contested 

 seriatim, and more especially the films, by the French mem- 

 bers. M. Desnoyers, at the second sitting, in view of this 

 difference of opinion, and of the admitted difficulty in certain 

 cases of distinguishing the genuine from the counterfeit, urged 

 that the material proof was, above all, a question of gisement ; 

 and that if the position of a hache in the deposit were proved 

 to be unquestionable, the hache ought to be accepted as 

 genuine, whatever might be the characters which it presented. 

 Others of the French savants advocated the same view. One 

 of the English members replied that he fully admitted the 

 importance of the evidence yielded by the gisement ; but that
