52 NEW OXYCHLORIDE OF LEAD. 



Analysis, kindly made by Mr. O. E. White, of 

 llobart': — 



PbO = 74-04 

 As.,0-, = 260 

 P.,07 = 210 

 SK,0-, = -50 

 Cr ' = 20- 



' Locality. — In the superficial workings of the Britannia 

 Mine, Zeehan. 



It is evidently rare, and, so far as known, confined to 

 the locality mentioned. One remarkably fine specimen 

 contains about 200 perfectly formed implanted crystals. 

 The accompanying illustration fairly represents this 

 specimen. It is an attractive mineral when in large 

 groups, as shown, and is easily distinguishable from the 

 more abundant sulphate and carbonate of lead. It is 

 occasionally associated with fine groups of campylite.
