Introduction. 



During a visit to the Grampians in February, 1913, in conn- 

 pany with Mr. W. H. Ferguson, of the Geological Survey, I paid 

 a visit to the Stony Creek basin, near Hall's gap, from which 

 a considerable quantity of alluvial gold has been obtained. From 

 the gold-bearing gravels and sands a large number of australites 

 has been found from time to time. The gravels are quite shal- 

 low, and I understand that some of the australites have been 

 obtained from a depth of a few feet below the surface. I was 

 not successful in my search, but Mr. Charles D'Alton. of Hall's 

 Gap, showed me some which he had found, and generously pre- 

 sented to me for the Geological Museum of the University, two 

 small forms, of remarkable character. 



Last Aveek Professoi- Baldwin Spencer, C.M.G.. F.R.S.. Director 

 of the National Museum, showed me another remarkable form 

 of australite, from Western Victoria, recently presented to the 

 National Museum by Mr. H. Quiney. 



Professor Spencer kindly allowed me to describe this specimen, 

 with the tAVo presented to me by IMr. D'Alton.
