PALAEOLITHIC IMPLEMENTS 63 



years in the Nile Valley met with a drift that might 

 represent the rubble-bed that underlies the Alluvium 

 of the valleys of Western Europe. 



Nevertheless, judging by analogy, it would appear 

 that Palaeolithic Man did inhabit the Nile Valley, for 

 flint or chert implements of the precise type of those 

 found in the river drifts of the Thames and Somme 

 Valleys have been discovered there by Sir John Lub-' 

 bock, Prof. Haynes, and Mr. F. N. Flinders Petrie, 

 but they were all on the surface and nothing is known 

 of the beds from which they may have been derived. 1 

 Possibly, they may be specimens originally dropped 

 or lost on the surface, or embedded in some old fluviatile 

 drift. The sand- worn condition of one side of one of 

 the specimens shows it to have been long exposed 

 to drifting sand-storms. 



Another circumstance tending to show that Egypt 

 has not been submerged since the Palaeolithic period 

 is that several of the animals which lived in Western 

 Europe and North-Western Africa before the time of 

 the Eubble-drift disappeared in those areas after that 

 event, whereas they survived in the Nile Valley to 

 Historic times ; such for example are : 



Lion. Spotted Hyaena. Hippopotamus. 



Panther. Caffir Gat. African Elephant. 



This may be merely a coincidence, but it seems to 

 me to have a collateral bearing on the question, and 

 to afford, with the other facts named, grounds for 



1 Palaeolithic Man in Egypt may have preceded his appearance 

 in Europe.
