The measurements of the lower jaw show only moderate dimensions
throughout. The angle (mean of the two sides, which usually differ
somewhat in this respect) averages decidedly higher in the females
(130°), which is not always the case in American crania. Thus among the
Arkansas and Louisiana mound crania it averaged 118.5° in the males, or
practically the same as in the Munsee; while it was only 122° in the
females, or eight points lower than in the Munsee of the same sex.
