New York: Charles Scribner's Sons, 1923. First edition. Hardcover. Near Fine / Near Fine. Original black cloth, lettered in red. The dust jacket shows some wear at the corners and the spine ends, else fine. A fascinating and infuriating look at racial groups and how mankind would be better off if these groups remained intact. The Scribner's jacket blurb states, "A powerful argument for the permanent domination of the world by the white race." A very scarce title and even scarcer in the jacket. This man taught at Dartmouth!
