The ossiferous layer lay 4.55 m. from the surface and was 0.60 m. 

 in thickness. Beneath it were sterile layers of gravelly sand and clay. 

 In addition to the human lower jaw and ulna there was also found in 

 the ossiferous layer an animal bone with a neatly made artificial per- 

 foration. There is no mention in the report of any stone implements. 



A final report on the exploration of the La Naulette cave, accom- 

 panied by a chart showing the deposits, was made by Dupont in 1867.* 

 He reached the conclusion that the two human bones were in all 

 probability introduced in the cave by man himself and that they were 

 the remains of cannibalism. He also states definitely that notwith- 

 standing a most careful search, no worked stones nor any remains 

 of fireplaces were found in the cave ; there were, however, intention- 

 ally broken animal bones indicating human activity. 



After having submitted the human remains to various experts, 

 Dupont proceeds to their description, and then gives the following 

 measurements : 



mm. 



Height at chin 31 



Height at M2 22 



Thickness at chin 15 



Thickness at last molar 16 



The ulna is also briefly described by Dupont (ibid.). He tells us that 

 the bone, the head of which is missing, shows a " normal " form ; 

 that it belonged to an individual of small height ; and that its aspect 

 as well as proportions indicate that it proceeds from a female skeleton, 

 from which also may have come the lower jaw. The lower jaw was 

 studied intensively by Topinard, and since then more or less by most 

 other workers in human Prehistory. 



In 1923, thanks to Professor A. Rutot, Director of the Musee at 

 Brussels, the writer was able to examine the original. The specimen 

 comprises the frontal part and left body of the jaw. It is a normal 

 bone of primitive build. It belonged to an adolescent female ; the 

 socket for M3 indicates that the tooth had not yet fully erupted. It 

 resembles closely the female lower jaws of Krapina. 



The bone is stout, especially for a female ; at the same time the 

 body is low, indicating the female sex. The symphyseal region is 

 nearly flattened from side to side between the elevations of the canine
