FIG. 23. Comparison of the right half of the lower jaw of A, Modern European ; B, Eoan- 

 thropus from Piltdown ; and C, Chimpanzee. The size of the drawings is two-thirds 

 of the linear dimensions of the actual specimens. The dotted outline in B represents the 

 part which was wanting in the original specimen and was thus re-constructed by Dr. 

 Smith Woodward. .A" in A is the bony chin or " mental protuberance " ; in B and C it 

 marks that part of the jaw which would become the mental protuberance were the 

 palisade or line of teeth retracted as in A.
