ANTHROPOMETRY

In plano-convex and related femora the shaft is so deformed and the 

 linea-aspera so displaced, that the measurement of the diameters is 

 impractical and should be omitted. 



Circumference of the shaft at middle as taken by some observers 

 and contrasted with the length of the bone, gives data of some value for 

 sexual identification; but the same may be done with the mean of the 

 two diameters.

Notes: To take the ordinary length of the tibia introduce the spine 

 into the orifice provided for this purpose in the vertical part of the 

 osteometric board, apply outer parts of the condyles to the vertical 

 outside of the orifice, let body of the bone repose on the horizontal 

 part of the board, and apply block to the most distant point (mal- 

 leolus).
