Extract

On November 14th, 1892, Prof. J. A. Krenner read before the Hungarian Academy of Sciences an account of a new silver ore from Felsöbánya, to which he gave the name of Andofite. It was described as orthorhombie with a : b : c = 0.97756 : 1 : 0.86995, and as having the chemical composition 2PbS.Ag2S.3Sb2S3.

page 289 note 1 Before the idea of tbe identity of the mineral with Sundtite and Andorite had been entertaiued, the axial ratios were deduced from the angles bn = 72°2½ and by = 37°58½, as a : b : c = 0.324 : 1 : 1.281.

The amount of this was too small to make a satisfactory determination of the chemical compnsition possible. PSblmann mentions antimony oxide as a yellow powder dusted over the crystals.
