Height of obturator foramen. 



Breadth of obturator foramen. 



Interobturator width: The distance between the inner 

 margins of the obturator foramina. 



Breadth of innominate bone: The distance between the 

 angle of the os pubis and the most distant part of the ihac 

 crest, generally a little above the posterior superior iliac spine. 



Breadth of ilium : The distance between the anterior 

 superior and posterior superior spines of the ilium. 



As far as possible, the measurements about the innominate 

 bone were taken on the right side. 



The indices used, and the formute by which they are 

 calculated, are as follow : — 



Breaclth-heiglit index 

 Index of the pelvic brim . . 



Index of the pelvic cavity 

 Sacral index 



Obturator index .. .. .. — -^^^^-r : — -. — r— ,- — 



Obturator height 



The following table gives the breadth and height of the 



whole of the pelvis, and the height-breadth index, or proportion 



between the two, distinguishing the sexes, and giving the 



maximum and minimum as well as the average in each case.

The greater height of the male pelvis, not only absolute, 

 but relative to width, is clearly shown in the table. 



The measurements of two Maori pelves, both males, are 

 given by Sir William Turner. '■= The maximum width of one 

 is 255mm., and its height is 221mm. — a pelvis, therefore, 

 somewhat narrower and higher than the average of my male 

 specimens. Its index is 87, higher than that of any in my 

 series. In the other pelvis, which was scarcely full grown, 

 the breadth is 238mm., the height 188mm., and the index 

 79mm.
