It will be observed, in the first place, that at the middle of the 
shaft the mean of the two diameters at the upper flattening in the 
Munsee is smaller in both sexes and on both sides than that in either 
the whites or the negroes, thus indicating that’ the bone is more 
slender. 
The most striking points brought out by the data are, however, 
those relating to the degree of the flattening in the subtrochanteric 
region in the different racial groups. The Munsee femora are decid- 
edly flatter-than those of the whites, which in turn are slightly flatter 
than those of the negro. As a result the platymeric index in the 
Munsee is considerably below that in both the other races. 
Taking the two diameters separately it will be observed that the 
diameter maximum or breadth is frequently larger in the left than in 
the right femur. This is true in both sexes among the Munsee and 
in the white females and negro males. In the white males the meas- 
urement is equal on the two sides, and in the negro females it is 
slightly larger on the right than on the left. In all probability the 
tendency of the left femur to be shghtly broader than the right at the 
subtrochanteric flattening is quite universal,
