Munsee, the humero-femoral index ( BioaTaylar Ianeth “of Temir )i approx- 
imates 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.

THE SHAFT 
The measurements taken at the middle of the shaft in the Munsee 
femora indicate generally a moderate development. The mean 
diameter is smaller in both sexes than it is in ordinary American 
whites and negroes! of ‘the same stature. The same condition, 
though in a somewhat lesser degree, was observable in the Arkansas 
and Louisiana Indian femora, and there are reasons to believe that 
it is common to other Indian tribes, if not general in the race. The 
whites and negroes used here for comparison are of course those of 
the working classes, or such as find their way into dissecting rooms. 
As to the strength of the femur on the two sides of the body, 
the difference in the Munsee, as well as in other Indians and racial 
groups, is very small. However, in the males a slightly higher aver- 
age mean diameter is seen in the left femur, while in the females the
