The size of the head, as is well known, increases with stature. This
increase is not uniform, but progresses in a diminishing ratio. The
fact holds true in all races, though the exact values of the ratio
with the different racial elements have not as yet been determined
definitely. In the case of skeletal remains, in which it is not
possible to learn the exact stature, the most suitable manner of
obtaining light on the subject is to compare the length of the femur
with the cranial capacity, by which means we ascertain the number of
cubic centimeters of the capacity that correspond to each centimeter of
the length of the femur. The following data give the results of such
a comparison among the Munsee and on Indian skeletal remains from
Arkansas and Louisiana.[23]
