EEPORT ON THE BONES OF THE HUMAN SKELETON.

The Hindoo pelves were a male and a female. In them, as in the male Sikh, the alse 
of the ilium were expanded. In the Sikh and female Hindoo the iliac fossae were semi- 
translucent, but this was not the case in the male Hindoo. The Sikh dominated largely 
in its dimensions over the Hindoos, indeed it is one of the largest pelves that I have 
measured in the course of this inquiry. But notwithstanding this difference in absolute 
size, there was in many jDarticulars a great similarity in the relative proportions of the 
Sikh and the male Hindoo. The breadth-height index of the male Hindoo, 78, closely 
approached that of the Sikh, 79. The obturator indices in these males also closely 
approximated, in the Hindoo being 66, in the Sikh 68, whilst the female Hindoo 
again had a higher index, 71. Although in both the Hindoo and the Sikh the transverse 
diameter of the pelvic brim was greater than the conjugate, yet in these males the inlet 
narrowed towards the symphysis so that the outline of the brim approximated to the 
cuneiform. In the female Hindoo this narrowing was not so rapid, and the outline of 
the brim was more rounded. The pelvic index in the male Hindoo was 89, in the 
Sikh 90, in the female Hindoo 93. In both these males the intertuberal diameter was 
about 30 mm. below the transverse diameter of the brim. The inferior sagittal diameter 
in the male Hindoo and in the Sikh somewhat exceeded the conjugate ; in the female 
Hindoo it was somewhat below the conjugate. The pelvic cavity both in the male 
Hindoo and in the Sikh was deeper than in the female Hindoo. They differed in the 
relative value of the iliac index, for in the Hindoo it was 132, in the Sikh 125. The 
pubo-innominate index in the male Hindoo was 42, in the Sikh 44 ; the ischio-innominate 
index, again, in the male Hindoo was 44, in the Sikh 43. They differed also in the sacral 
index, which in the Sikh was as high as 124*5, and in the male Hindoo only 109, whilst 
in the female Hindoo it was 127; the breadth of the sacrum, 121 mm., in the Sikh, was 
indeed quite remarkable for a male pelvis, but as the subpubic angle was only 62°, this 
great sacral breadth, though associated with a correspondingly wide brim, had not 
occasioned an opening out of the subpubic angle. 
The Chinese pelvis in its external dimensions was in most of its measurements larger 
than the Malay. In both the iliac fossae were somewhat thinned, but the alee were 
expanded, flattened, and thrown outwards in the Chinese, and more nearly vertical and 
looking inwards in the Malay. In the Chinese the anterior border of the ilium slo23ecL 
upwards and outwards, and the anterior inferior spines were 173 mm. from each other, 
being 78 mm. less than the diameter between the anterior superior spines ; in the 
Malay the anterior border of the ilium was nearly vertical, and the anterior inferior 
spines were 183 mm. asunder, being only 10 mm. below the distance between the anterior 
superior spines. The proportions of breadth and height were very different, the index in the 
Chinese being 73, in the Malay 85. The dimensions of the obturator foramen were larger 
in the Malay pelvis, in which the obturator index was 62, whilst in the Chinese it was 5 5 "5. 
They differed materially from each other in the shape and diameters of the pelvic brim.
