committed suicide; No. 2, a prominent politician during the civil war;
No. 3, a banker; and No. 4, a notorious assassin. Nos. 5 and 6 are negro
skulls. Further comparison may be made with the Jewish skull, as
represented in No. 7, in which the nasal bones project so far beyond the
general contour as to form a bird-like appendage.

A collection of Aleutian heads, as seen from a vertical point of
observation, when I looked down from the gallery of the little Greek
church at Ounalaska, presented at first certain collective characters
by which they approach one another. But anatomists know that a careful
comparison of any collection will show extremely salient differences. In
fact, individual differences, so numerous and so irregular as to prevent
methodical enumeration, constitute the stumbling-block of ethnic
craniology. Take, for instance, a number of the skulls under
consideration: in proportions they will be found to present very
considerable variations among themselves. The skulls figured by A and B
are respectively brachycephalic and dolichocephalic. The former has an
internal capacity of 1,400, the latter 1,214 cubic centimeters; but the
facial angle of each is 80°, and in one Eskimo cranium it runs up to
84°. If the facial angle be trustworthy, as a measure of the degree of
intelligence, we have shown here a development far in excess of the
negro, which is placed at 70°, or of the Mongolian at 75°, and exceeding
