PRINCIPAL SIR WM. TURNER ON 



cotyloid notch was deep, narrow, 19 mm. in width; on the left side its ischial cornu 

 was prolonged into a sharp process, which overhung the notch ; it seemed as if the 

 transverse ligament had been partially ossified ; on the right side the cornu was not 

 pointed but rounded. The antero-posterior diameter of the great sciatic notch was 

 diminished by the projection into it of a sharp ridge, 16 mm. wide, which was 

 prolonged from the ilium immediately below the posterior inferior spine.

When the bones were articulated the breadth of the pelvis at the tubercles on the 

 iliac crests was 246 mm., and the height was 185 mm., which yielded a breadth-height 

 index 74*9. Dr Garson* computed the breadth-height index in four Tasmanian males 

 as ranging from 77 to 84 - 6 mm., with a mean of 80. Both in breadth and height the 

 Brussels pelvis was smaller than in male Europeans, in whom M. Verneau gave 27 "9 mm. 

 as the mean breadth and 220 mm. as the mean height in sixty-three pelves with a 

 mean index 7 8 '8. The mean breadth of six Australian males recorded in my 

 Challenger Report was 252 mm., and the mean height was 194 mm., which 

 resulted in a mean breadth-height index 77. Though in the Brussels specimen the 

 index was below the Australian mean, when its index was conjoined with the indices 

 of Garson's male Tasmanians the mean was 78'6. 



The transverse diameter of the pelvic brim, 123 mm., much exceeded the conjugate, 

 95 mm., the form of the inlet was transversely ovoid, and the brim index 7 7 '2 was 

 distinctly platypellic. In its form and relative dimensions the brim approximated to
