On the Skeleton of an Aboriginal Australian. 65 



the portions of the limbs. One set, like that given here, tells us 

 comparatively little of ethnological importance, as the original 

 may have been a Rob Roy among his tribe, or else brachybrachial, 

 but an extensive series of such measurements would, doubtless, 

 be of value. 



The vertebral column showed no appearances of note. The 

 third cervical had a trifid spine, as is not uncommonly the case. 

 The spine of the sixth cervical was bifid, and the transverse pro- 

 cess of the seventh perforated at each side. The sacral laminae 

 were mesially ununited, and the spinal curvatures were smaller 

 than usual. The sacrum measured 3{ inches in length, and 46 

 inches in breadth, the average male European sacrum being 3*9 

 inches by 5 inches. 



The os innominatum is small, not unduly elongated, with no 

 pre-auricular groove (Zaaijer), but with well-marked muscular 

 impressions. The thigh bone has a small carina, and its neck 

 forms a large angle (123°) with the shaft. The anterior inter- 

 trochanteric and the ectogluteal ridges are strong and rough. 



The tibia has a tuberous external condyloid eminence for the 

 attachment of the ligamentum iliotibiale (Maissiat and Merkel), 

 a structure which I have always found to be of proportional 

 strength in all persons, with great powers of endurance in their legs. 



The skull presents the usual Australian dolichocephaly, and is 

 of the usual small size, with narrow frontal region. The sutures 

 are open and are comparatively simple, the lachrymo-planal being 

 reduced to a very short space 0*2" in length. There is a distinct 

 double temporal crest (HyrtL), a double supra-orbital hole on the 

 right side, the inner opening being for the supra-trochlear nerve. 

 The spheno-parietal suture measures 0'4" on the left, 0*35" on the 

 right. The occiput has two rough splenial ridges and a short 

 fissure exists behind each. The tympanic is separated from the 

 periotic by a distinct deficiency, and the post-glenoid process is 

 separated from the tympanic bone by a fissure continuous with 

 the glaserian. A strong supra-mastoid ridge exists, and strong 

 stylohyals; a narrow transverse glenoid cavity, and a vertical 

 anterior edge of the squamosal. The spine of the sphenoid has a 

 double styloid process, one external and one internal to the 

 foramen spinosum. The left lachrymal bone has an inferior 

 hamulus, and the chin process is small.
