The moral and intellectual character of the Africans is widely different in different nations.
The Negroes have little invention, but strong powers of imitation, so that they readily acquire mechanic arts. They have a great talent for music, and all their external senses are remarkably acute.
In disposition the Negro is joyous, flexible, and indolent; while the many nations which compose this race present a singular diversity of intellectual character, of which the far extreme is the lowest grade of humanity.
The American Race is marked by a brown complexion; long, black, lank hair; and deficient beard.
