Taking the antero-posterior and lateral diameters at the middle of
the shaft separately, we find several more interesting points. The
antero-posterior diameter in the Munsee (and the same is true of the
United States whites and United States negroes, as will be seen by the
following table) is practically equivalent in the right and left femora
in the males; but except in the whites it is perceptibly smaller on the
left side in the females of all groups. On the other hand, the lateral
diameter, excepting in the probably too small male negro series, is
invariably larger on the left than on the right side in both males and
females. Thus it may be said that the left femur is almost invariably
slightly broader on the average than the right, and this especially in
the females of probably all racial groups.
