Stone Implements in Lateritic formations. 29 



that they will turn out to be synchronous with those we 

 have now been describing. 



The same will probably be the case with the Detrital 

 laterite of Cuttack and the S. W. frontier of Bengal — indeed 

 if these widely distributed lateritic formations should even- 

 tually be found to belong to the same series as the typical 

 laterite of the neighbourhood of Madras, but little doubt 

 can remain that the whole or very nearly the whole Indian 

 peninsula has undergone a considerable elevation since man's 

 first advent. 



The non-discovery hitherto of any remains of the animals 

 contemporary with the Implement manufacturing men of 

 Southern India, render it as already stated above, impossible 

 at present to correlate the lateritic formation more nearly 

 with the European formations which contain remains of 

 ancient man. There is no reason why we may not yet find 

 such remains and ascertain whether any representatives ex- 

 isted in India of the gigantic extinct Mammalia which were 

 the congeners of ancient man in N. W. Europe — such as the 

 Elephas primigenius, E. antiquus, Rhinoceros tichorhinus, a 

 species of Hippopotamus and the ancient cave inhabiting 

 bears, hyenas and lions. 



On the period of time required for this great elevation 

 to be accomplished, it is impossible to speculate safely in 

 the absence of any satisfactory data. 



The greatest well ascertained elevation at which our Im- 

 plements have been found is about 370 feet above mean sea 

 level at Kircumbaddy, and at about 1J mile East of Arco- 

 num Junction at an elevation of very nearly 300 feet. 



If we attempt to form an estimate of the time required 

 for the elevation of the lateritic formations to such a height
