106 On the Occurrence of the Duwiond near Miidgee. 



The minerals characteristic of the Cudgegouy diamond area 

 are the lustrous black vesicular pleonast, brookite, and the variety 

 (c?) of corundum already mentioned. We are not a\Yare that 

 these minerals have been recognised in any other part of 

 Australia with the exception of brookite, which has been found 

 in Victoria. The source of these has not been traced, and it 

 will be interesting to notice whether they accompany the diamond 

 in any new localities which may be discovered. 



In suggesting that future discoveries of the Diamond are very 

 probable, we may state that at Trunkey Creek gold-field there is 

 a drift in most respects similar to that of the Two-mile Plat ; it 

 is found similarly situated beneath basalt, and we have seen one 

 diamond which has been obtained from it.
