The western as well as other Eskimo show arches that are about equal in absolute dimensions to those of our taller Indians, such as the Munsee, Arkansas, and Louisiana;[155] but relatively to stature the Eskimo arch is decidedly larger. The upper dental arch index (L×100/B), now being used in preference to the unwieldy "uranic index" (B×100/L) of Turner, is rather high, showing that the arch is relatively, as well as absolutely, broad. The same index in the Munsee averaged in the males _82.8_, in the females _82.7_; in the Arkansas and Louisiana mound skulls _84.4_ in the males and _85.1_ in the females. Data are needed here for more extensive comparisons.
