rate of 77*9%. Three other pieces weighing collectively four 

 hundred weight, and many smaller samples were obtained in 1891, 

 the total amount of this mineral raised, between January and 

 September of the year referred to, totalling six tons seven hundred 

 weight one quarter and eighteen pounds, and which gave a silver 

 return of 142*554 ounces troy. 



A specimen of dyscrasite from Broken Hill, examined by me, 

 was found to have a Sp. G. of 9*70; lustre bright metallic ; colour 

 silver-white on newly broken parts, but tarnishing to yellowish- 

 white on exposure. The containing gangue was calcite in which 

 the mineral occurred in beautiful arborescent forms. B. B. on 

 charcoal gives coating of oxide of antimony and a remaining 

 globule of silver. Dyscrasite is said also to occur in beautifully 

 perfect crystals, in calcite in the mine before referred to. 



Note. — A most interesting paper on the occurrence of dyscrasite 

 at Broken Hill, was read by Geo. Smith Esq., of Broken Hill, at 

 the inauguration of the Australian Institute of Mining Engineers 

 at Adelaide in 1893, and the statistical information quoted in 

 these notes has been gathered from the paper referred to.
