human oriL;in of the sub-crag flints h'es in the suggested 

 traces of an evolution in vvorknnanship of the t\-pe shown 

 in examples of mid-glacial age. It must be remembered, 

 however, that these later flints are very few in num.ber, 

 and that the best of them were collected by a quarr\'man 

 presumably accustomed to Paheolithic flints, hence not 

 unlikely to be a plausible illustration, ruder types having 

 been inevitably overlooked. 



This evidence is now discredited by some flints which 

 recently came into my hands. Amongst some implements 

 from Hackney (obtained from the well-known dealer, 

 Mr. F. H. Butler) are four flints which agree very closely 

 with Mr. J. Reid Moir's Rostro-carinate type. They 

 agree exactly in colour, patiiiation, and the character of 

 the flint with t}'pical early Acheulean or Chellean imple- 

 ments from the same locality. P^our of them are described 

 and two figured in detail in an appendix to this paper. 



Comparison of these descriptions and figures with 

 those given by Sir E. Ray Lankester of sub-crag flints 

 will show the complete resemblance of the two series in 

 shape, size, character of the flaking, and general roughness. 

 Sir E. Ray Lankester has already shown that the same 

 form occurs in the upper Miocene of Aurillac. 



It is inconceivable, in view of our present knowledge 

 of early flint industries, that a tool should retain exactly 

 the same form and rudeness over this enormous period. 

 I have little doubt that search would show the same form 

 in many of the flint-bearing gravels. 



It would be interesting and instructive to collect all 

 the flints from the Red Crag stone bed which show an)'- 

 traces of flaking, without reference to their form, and 

 then compare the series so arrived at with the Rostro- 

 carinate and other types described by Sir E. Ray 

 Lankester.
