20. Bismuruire (Carbonate of

20a, Bismurarre (Carbonate of 
Bismuth). 
Tarrangower. 
Occurs in tolerable abundance in the washing-stuff of Ramshorn 
Gully, Sandy Creek, Tarrangower. 
It forms grey or yellowish-white 
round and nodular pieces, from a few grains to several penny weights, 
the larger of which show usually, on being broken, a dark color, tending 
towards grey—metallic in the centre. 
Its chemical composition, as 
determined by a quantitative analysis by Mr. J. C. Newbery, is as 

follows :—

1, Small grains, of uniform color throughout. 
2. Larger grains, with discolored centre, 
3. Piece $-inch in diameter, with dark centre, 
As shown by these results, the mineral cannot be considered as a 
well defined species. There is every reason to suppose, that it has 
actually been formed, or at least grown, in the drift, small particles, 
derived from quartz reefs in the neighborhood, having perhaps served 
as nuclei. Several specimens have been found enclosing small water- 
worn specks of alluvial gold. ,
