"If (all types of men) are taken, from the first, and one placed after another, like the Negro from Zanzibar, in the Southern-most countries, the Negro does not differ from an animal in anything except the fact that his hands have been lifted from the earth -in no other peculiarity or property - except for what God wished. Many have seen that the ape is more capable of being trained than the Negro, and more intelligent."
