in a sliding shelf which holds the protractor with margin parallel to the base line, 

 and a needle made to coincide with the line previously drawn across the head indi- 

 cates the degree of torsion. 



The results obtained by this method vary from those of Broca, who made use 

 of the inter-epicondilar axis in place of the axis of the elbow joint. An objection 

 to the use of the epicondyles is their variability in size and direction.

Femtirs. — The index of diameter is taken with the caliper square at the mid- 

 dle of the shaft. The percentage is derived at by dividing the antero-posterior 

 measurement by the lateral measurement. 



No femurs were measured as to index where the shafts were incomplete, an 

 accurate determination of the center of the bone being thus assured.
