■252 A XATUKAL ' EOLITH ' FACTORY [vol. IXXVl, 



Mr. J. F. N. Green felt that he must protest against a 

 statistical error. The demand that provably natural objects equal 

 •to the best Eoliths, etc., should be produced was unreasonable, since 

 the selectors of the latter had all the chipped flints of England to 

 work on, while flints absolutely proved to be naturally flaked were 

 few. Those who held Eoliths to be artefacts had a held a million 

 times larger than that open to the holders of the opposite view, 

 and should obviously obtain specimens more closehy resembling 

 human work. Nevertheless, their results were so small that 

 Mr. Reginald Smith, who had previously referred the Society to 

 the British Museum, now went to Cardiff. A case which had to 

 rely on a specimen, hyperselected from an almost infinite range, 

 was in a bad way. 



Mr. F. N. Hawaed exhibited, in support of the Author's argu- 

 ments, a small series of ' chipped flints ' of various forms — 

 bulbous flakes with and without edge-chipping, pieces of flat Hint 

 with 'one-edge' chipping (on one side only), and several ' rostro- 

 ■carinate i'liplement' forms from the Basement Bed (Zone C) at 

 Eaton Pit, Norwich. He also exhibited a split unrolled Chalk- 

 flint, found in three separated pieces (one above the other) in the 

 gravel of a pipe in Eaton Pit. One piece showed a sharp split 

 edge, well chipped along one side only, in a manner exactly similar 

 to specimens in the Basement Bed (Zone C) above. 



These specimens, the speaker considered, furnished important 

 evidence, as they are not the result of searching over a great 

 amount of material or over a large area, nor the result of ' selection.' 

 Practically every flint in the Zone is more or less chipped, some 

 far better than others. 



The chipping on these specimens is of the same order as, and 

 often exactly similar to, that of the so-called ' implements of the 

 sub- Crag ', and of many of the ' Eoliths ' of the Kent Plateau. 



In the first instance, the chipping on these Norfolk specimens 

 was probably due (as in the case of the Author's specimens) to 

 movement in the Basement Bed caused by dissolution of the Chalk 

 below, and further, in the case of the Eaton specimens, to 

 transportation as the gravel shifted one way or the other since its 

 deposition. During this subsequent movement, the sharp edges 

 would be further chipped, crushed, and abraded. 



The speaker felt confident that the Author had found evidence 

 which bears directly on the probable origin of the so-called imple- 

 ments of the 'sub-Crag' and the ' Basement Bed' of East Angiia 

 and possibly some of the ' Eoliths ' of Kent. In conclusion, he 

 paid a personal tribute to the careful and thorough investigation of 

 the fracture of flint carried on by the Author for very many years. 



The Author thanked his supporters in the discussion, and, in 

 answer to criticisms, said that he considered the Mousterian 

 affinities to have been exaggerated by several of the speakers. The 

 series exhibited was of purely Eolithic character, but there were a 

 few specimens which resembled Mousterian work to an astonishing 

 degree. In opposition to the remarks of Mr. Reginald Smith,
