Note 1 — LECTURE I. THE PHYSICAL ELEMENTS OF ETHNOGRAPHY.

The cranial indices on one of these islands varied from 70 to 83. The excessive claims of craniometry have been severely but justly rebuked by Moriz Wagner, in his thoughtful work, Die Entstehung der Arten durch räumliche Sonderung, s. 528, sq. (Basel, 1889), and more forcibly censured by Waitz, Anthropologie der Naturvölker, Bd. I., ss. 84-88. The French school of anthropologists have been especially one-sided in their devotion to this one element of the science. Among other great naturalists, Charles Darwin was careful to point out the variability of the skull as an anatomical part. (The Descent of Man, p. 26.)
