"The Races of Man. - At the present time there exist upon the earth five races or varieties of man, each very different from the others in instincts, social customs, and, to an extent, in structure These are the Ethiopian or negro type, originating in Africa; the Malay or brown race, from the islands of the Pacific; the American Indian; the Mongolian or yellow race, including the natives of China, Japan and the eskimos; and finally, the highest type of all, the Caucasians, represented by the civilized white inhabitants of Europe and America."
