mentioned are as follows, remembering that, unless there is much dis- 

 parity in leg-length, a low index means a short arm, and vice versa. 



* The total length in millimeters of Fuegian limbs (bones) averaged at 758 mm. 

 for males, and 709 mm. for females, according to Martin. These were taken from a 

 large number of individual bones. 



length of humerus X 100 

 4. Humero-femoral index - T .-^ 



length of femur 



This comparison gives the relative length of the humerus, when compared 

 with the thigh. Martin gives the following values:- 



The indices that follow have been seldom used, and some of them may 

 even have never been practically employed. They are placed here 

 mainly to show some of the many possible combinations, since any one of 

 these or similar ones may at any time be found to clearly present a certain 

 new relationship. To guard against an excessive employment of indices, 

 one should always have in mind exactly what real relationship a given 

 index is intended to show, and never use one (in published writings) 

 merely for the reason that it has never been employed before.
