SOME NOTES ON THE EARLY HOMINID^E 211 
with the fact that the mylo-hyoid ridge and the surface of 
attachment for the internal pterygoid muscle on the inner 
aspect of the angle and ascending ramus are poorly developed, 
one may be reasonably allowed to conclude that the race 
represented by Eoanihro'pus Dawsoni was speechless.

covery a few months later of a canine tooth shows that the 
modelled teeth are in harmony with nature. 
The teeth are of great size, eclipsing all the members of 
the Hominidae with the exception of the Java man. 
The Piltdown skull is in all probability contemporaneous 
with the Palaeolithic implements found in its proximity. These 
implements point to the Chellean epoch, and Woodward’s 
explanation of the presence of such a markedly simian jaw 
on a Chellean horizon is that this race, living in the region 
of Britain, was the last remnant of a very ancient stock, which 
probably was exterminated by Homo Heidelbergensis.
