mon form. Indeed, judging from a plaster cast in the Army Medical Museum, we believe it to be 

 the form of the celebrated femur of Cro-Magnon, whereof the index is 128. There is no suggestion 

 of disease about the cox* nor about the leg bones of this negress's skeleton, nor is there any pecu- 

 liarity of the skeleton as a whole which in any conceivable mechanical means could have brought 

 about such a result. 



Two other hunchbacks, the one mentioned as having the minimum index of the section of 

 the femur, and also No. 938, an Alaskan, show no such peculiarity. 



In connection with platycnemia let us mention the Bannock male. No. 2133 (Table Lxxvii). 

 The indices of his tibi* are 85.07 for the right and 93.75 for the left. These figures, while not the 

 highest on record, are nevertheless very high, and show an entire lack of platycnemia. \f we may 

 so express it. This is not what we should expect to find in an Indian skeleton, according to the 

 facts learned in pursuing our investigation. 



It happened thrice in our series of tibiae tliat the nutrient foramen of a certain tibia was so 

 very far out of normal place that it would falsify any measurement. Upon finding such a bone 

 we would compare it to its fellow of the opposite leg of the same individual and measure it at a 

 position corresponding to the level of the foramen in the latter. This is indicated on the margin 

 of our tables.
