The percental relation in length of the femur to the humerus in the
Munsee, the humero-femoral index
maximum length of humerus × 100
———————————————————————————————,
bicondylar length of femur
approximates in both sexes 72, which is very near the average in human
races generally. The similarity of this important relation in different
racial groups, as may be seen from the measurements by the writer in
the next table, is quite remarkable.
As a rule the humero-femoral index is in both sexes slightly higher on
the right than on the left side, and the Munsee form no exception in
this particular. As to sex, while in all branches of the whites, as
well as in the United States negroes, the male index on both sides is
slightly higher, in the Munsee, as well as in other Indians, the index
in the male is slightly lower than that in the female. These features
are all connected, of course, with the peculiarities of the length of
the Indian humerus as well as the femur, outlined in other chapters.
