The indices for other races collected from various sources, espe- 

 cially Turner's Monograph, are : — 



THE PELVIS. 



Five pelves were available for examination, though for various 

 reasons a complete series of measurements could not be taken. 



The measurements comprised : — 



The Maximum BreadtJi between the Iliac Crests. 



The Height of the Innominate Bone from the iliac crest to the 

 lowest point on the tuberosity of the ischium. 



The Breadth of the Innominate Bone between the extremities of 

 the anterior and posterior iliac spines. 



The Maximum Transverse Diameter of the Pelvic Brim from the 

 mid-point of the promontory to the mid-point of the upper border 

 of the posterior surface of the symphysis pubis. 



From these three indices may be computed : — 



m, 71 7 ■ T 7 Breadth between iliac crests x 100 



The Pelvic Index = v-t^^t f~. -. -, •

The Innominate Index = Breadth of innominate bone x 100 ^ 



Height of innominate bone. 



The pelvic index was computed in two skeletons : —

Maximum distance between iliac crests. . . 201 191 



Height of innominate bone 177 172 



Pelvic index 880 901 



Turner obtained from one male an index of 91.
