GENERAL CONCLUSIONS. 33 



Why eminent men in all ages, after ex- 

 hibiting great proficiency or skill, either 

 declined or failed to advance. If some men 

 of transcendent genius seem exceptions, they 

 are so few that the exceptions tend to prove 

 the rule. 



Why Negroes, Kaffirs, or other inferior 

 races cannot raise themselves, or be raised, 

 to the level of the white races. 



Why a negroid hybrid of dark colour may 

 possess the intellectual faculties of a white 

 race ; or, 



The futility of attempting to educate 

 a brain above the capacity with which it 

 has been endowed.
