240 Mr Solly, Liveingite, a new mineral from the Binnenihal. 



The crystals were finely powdered and then examined in the 

 manner described in a former publication (Min. Mag. XII. 289). 



The amount of substance placed at my disposal was '5 gram 

 and this was used in the single estimation. The results obtained 

 were 



Pb = 47-58 



S = 24-91 



As = 2693 



99-42 



A small trace of Iron was present, but could not be estimated. 

 The percentages required for a mineral having the formula 

 4PbS 3As 2 S 3 are 



Pb = 48-75 



S = 24-61 



As = 26-64 



10000
