From Darwin to Hitler
"The Negro is far removed from the European and close to the ape through its small build, through the relatively small breadth of its skull, through its relatively long upper limbs, and further the relatively short length of the thigh....
Also the Negro is more animal, in that it gives off a disgusting odor, distorts its face in grimaces, and its voice has a harsh, grating tone."
