THE BURBUNG OR INITIATION CEREMONY. 111 
In conclusion it may be remarked that with the aid of this 
extensometer, the behaviour of materials under stress may be 
studied with a thoroughness, that heretofore was very difficult if 
not practically impossible. The elasticity, solidity, plasticity and 
nachwirkung of materials may in the future be examined in larger 
specimens than have generally been used in the past. A series 
of exhaustive investigations in regard to these, to the effect of 
temperature, and to the influence of the duration of the applied 
stress, in determining the resultant deformations, ought to afford 
results valuable alike to the physicist and engineer.

Introduct y.—In two papers contributed to the Anthropological 
Institute of eeks Britain,’ I gave a short account of the Burbung 
of the northern section of the Wiradthuri tribes, who occupy the 
country commencing somewhere about the Barwon River, and 
*xtending southerly up the Macquarie, Castlereagh, Bogan, and 
other rivers, to the sources of the Lachlan, New South Wales. I 
also communicated a paper to the Royal Geographical Society of 
Australasia, * Queensland, on the initiation ceremonies of the tribes
