at Dundas it was discovered forming a dense compact lode, 

 the fractures of which contained bands and coatings of the 

 mixed oxides of antimony and lead. At this locality it 

 occasionally forms bunches of fine acicular crystals which 

 are implanted upon brown spar, and it is not uncommonly 

 intermixed with boulangerite and galena. 



At Zeehan a considerable quantity of this mineral closely 

 resembles schultzite. In colour and streak it is lead-grey ; 

 lustre dull, metallic, and silky ; very brittle, with a sub- 

 conchoidal fracture ; hardness, 2*5 ; specific gravity, mean 

 of five examples tested, 5-98. On coal it is very fusible, 

 depositing white antimonial sublimate. It is found in 

 masses, often with blende, intermixed with galena, in 

 various mines at Zeehan.
