204 NATURAL HISTORY OF 



the peculiarities of the Negro type strongly marked. 

 Among them, in particular, the Naga tribes practise 

 circumcision, and have other eastern indications about 

 them ; the Cumbric Negroes may belong to this branch ; 

 and the Mocos, who file the teeth in order to resemble 

 the Lion, are still cannibals, and the most savage of the 

 Papaw nations. Like the eastern Papuas, they are of a 

 dirty black colour, and have the same Jewish rites as the 

 rest. Hebrew or Semitic words occur in their dialects, 

 as in the Houswana tongues. Ideas, and perhaps 

 affinity with the Angola and Benin tribes, recall to 

 mind the still existing barter trade across the continent 

 to Mozambique, and this may point out the route from 

 the east by which they may have come to their present 

 location; for, had they spread from west to east, no 

 oriental words or institutions would be found in their 

 ancient national dialects or habits. 



In Eastern Africa, the woolly haired races, though 

 occupying a vast extent, are likewise of intermixed 

 origin. The whole east coast is possessed by nations 

 tinged with Arabic blood ; the extreme south by appa-

 Numidians appear to have been propelled by Arabian 

 conquerors, and to have originated the red and black 

 Poulas, so called in proportion as the brown or black 

 colour of their skins predominates. These have horses 

 and camels, unknown to all other Negroes, and are now 

 Moslem. The JalofFs are a branch of this stem ; and
