1-4 Mr. R. Bruce Foote on the occurrence of 



and which no where exhibits a thickness of more than 

 15' or 16' at the greatest. 



The lateritic conglomerates, gravels and sands all ex- 

 hibit the appearance of deposits rapidly accumulated, for 

 although the formation of the prodigious quantities of 

 quartzite shingle and gravel they contain, must have re- 

 quired a period of considerable duration for their production, 

 yet can such period not be referred to the laterite age, but to 

 one of far greater antiquity. 



As already before mentioned, this shingle was derived 

 from the Sattavedu conglomerates which belong to the 

 Stri Permatoor series. 



The evidences of the artificial origin of these Indian Stone 

 Implements are the same as those already so often given of 

 the flint Implements in Europe— namely their all showing, 

 however rude, that there was design in the shape given to 

 them. This cannot be doubted by any one who has had the 

 opportunity of examining even a moderate number of these 

 Implements — and the figures given of some selected specimens 

 will, it is trusted, amply satisfy even the most sceptical 

 that design is clearly traceable in all, however various their 

 shapes may be. 



As Mr. Prestwich originally pointed out in his ad- 

 mirable paper read before the Royal Society in May 

 1859,* the casual resemblance of a piece of naturally 

 broken flint to an Implement for warlike or industrial pur- 

 poses is not an impossibility, though such resemblances are of 

 extraordinary rarity — for no natural causes that are known 

 would produce such an effect. 



If a pebble of flint or quartzite, which in its fracture 

 differs from flint only in so far as depends on the greater 

 coarseness of its grain, is exposed to blows and friction in 

 the current of a rapid and powerful stream, it is either gra-
