forgeries we may be certain : firstly, because they have 

 been found in situ by many excellent observers — by all, 

 in fact, who have looked perseveringly for them ; and 

 secondly, because, as the discolouration of their surface is 

 quite superficial, and follows the existing outline, it has 

 evidently been produced sinee the flints were brought to 

 their present forms. This is 

 clearly shown in Fig. 57, which 

 represents a fractured surface 

 of Fig. 56, and shows the dark 

 natural flint surrounded by 

 the altered surface. The for- 

 geries — for there are forgeries 

 — are of a dull lead colour, 

 like other freshly-broken sur- 

 faces of flint. The same evi- 

 dence justifies us in concluding 

 that the implements are coeval 

 with the beds of gravel in which 

 they are found. 



7. Without counting flakes, 

 several thousand flint imple- 

 ments of the Palaeolithic Age 

 have been discovered in north- 

 ern France and southern Eng- 

 land. These are all of types which differ considerably 

 from those which came subsequently into use, and they 

 are none of them polished ; we may therefore, I think, 

 infer that the art of polishing stone implements was as 

 yet unknown. 



8 and 9. In the same manner, I think, we may 

 safely conclude that the use of metal and of pottery
