If this method, the only possible method, is applied in the 

 case of Piltdown, the evidence is quite overwhelmingly in 

 favour of an early pre-palaeolithic date for the human bones 

 found there. There appears to be no possibility of regarding 

 them as of palaeolithic antiquity. 



In my judgment then we have most definite and clear 

 evidence that the pre-palaeolithic peoples are abundantly 

 represented in this part of the world. This conclusion is based 

 on the following facts. 



i . The discovery in various parts of England of different 

 kinds of flint implements in deposits which are of a greater 

 antiquity than those containing the earliest palaeoliths. 



2 . The discovery at Piltdown in Sussex of the remains of a 

 very primitive type of human being in intimate association 

 with certain definite Pliocene mammalian forms, and the 

 earliest kind of flint implements known to science. 



The neolithic and palaeolithic stages in this country are 

 fairly well known, but the vast pre-palaeolithic periods await 

 examination. 



These periods are fully represented in England, and the 

 flint implements, etc., contained in the deposits laid down 

 during these epochs must be collected and investigated. 

 Such an investigation, I submit, will show that the evidences of 

 man's pre-palaeolithic history are as abundantly represented 

 here as in any other part of the world, and lead us to be careful 

 in speculating as to unknown Asia's monopoly in this direction. 



Note. — In the article on "The Relationship of the most 

 ancient Flint Implements to the later River-Drift Palaeoliths " 

 in Science Progress, July 19 17, p. 93, fig. $a does not show
