were not the exterminators of the earlier inhabitants seemed to be 

 shown by their own traditions, from which one learnt that they never 

 encountered on their migration southwards any other human in- 

 habitants. Lower Palaeolithic man was extinct before the Bushmen 

 reached the Zambesi, perhaps as the result of epidemics or the same 

 mysterious causes as had led to the extinction of the horse in 

 America before its re-introduction by modern Europeans. The 

 Bushmen were probably the recent representatives of Solutrean 

 man, and thus of Upper Palaeolithic origin ; but, if an Upper Palaeo- 

 lithic European stage was now represented in South Africa by a 

 recent race, then a Lower Palaeolithic European stage might be 

 similarly represented by a chronologically Upper Palaeolithic race. 

 It seemed probable, therefore, that the implements exhibited 

 belonged to a Lower Palaeolithic race which inhabited the Zambesi 

 in Upper Palaeolithic times ; but this, according to the argument 

 employed, was the latest date that could be assigned to them, 

 since the next succeeding stage was represented by recent races 

 which were homotaxial with the Upper Palaeolithic. 



The Author hoped that the proof asked for by Mr. Lamplugh 

 of the volcanic character of what he had called ' tuff ' would shortly 

 be forthcoming on the arrival of samples of the material. The 

 reasons for a contrary opinion to that expressed by Col. Feilden, 

 that the detritus on the left bank above the Falls was Zambesi 

 gravel, were stated in the paper, and there the question must rest, 

 until further evidence became available.
