FROM GRAYS, ESSEX.

Terrace gravels, which are without doubt of the same age as the 

 gravels at St. Acheul. It also occurs in the still older palaeoliths, 

 the " Hill Group " of Sir Joseph Prestwich. Hence, in my 

 opinion, this type cannot be considered to be in any sense dis- 

 tinctive of a particular period. 



That there is a difference between the tools from Le 

 Moustier and the High Terrace implements cannot be doubted, 

 and judging from workmanship the latter are the older. In my 

 opinion the implements from the Middle Terrace of the Thames 

 are of the Mousterian age. To this period I would assign the 



A 



3 FULL SIZE 



LONGITUDINAL AND TRANSVERSE SECTIONS OF THE GRAYS IMPLEMENT, 

 ALONG THE LINES INDICATED IN PLATE VI. 



Palaeolithic Floors at Grays, Crayford, and Stoke Newington, 

 some of the implements from Ilford (several of the palaeoliths 

 from this locality are undoubtedly derived from the High 

 Terrace), and many other localities outside the Thames area, as 

 at Hoxne, Hitchin, Mildenhall, Caddington, etc. 



I have pleasure in presenting the implement above 

 described, to the Essex Museum of Natural History, and I 

 must not forget to thank Mr. F. W. Reader for excellent 

 photographs of the stone.
