In the following table we give the measurements of twenty males and ten females, all mature, the majority of whom belonged to the Arunta tribe. The measurements follow those recommended by Broca. The facial angle was determined by means of Broca's “facial and lateral goniometer” and it must be stated that, apart from the natural reluctance of the natives to remain sufficiently quiet under what was at least an uncomfortable and to them mysterious and therefore not agreeable operation, the thick hair on the upper lip made it very difficult to take the measurement satisfactorily. The greased and matted nature of the hair make it also difficult to be quite accurate with regard to other head measurements, while the habit of pulling out the hairs on the forehead render it sometimes a little difficult to be quite sure as to exactly where the hairs start on the forehead.

We did not attempt to obtain any skulls, for the simple reason that while the desecration of native graves might have enabled us to secure a few, it would at once have put a stop to work in other branches which we have been as yet more anxious to study than to obtain anthropometric data. To have opened native graves would have meant the closing of sources of information with regard to habits and customs.
