Grey Antimony. 



4, Veins, consisting almost entirely of the 'present species, have been 

 discovered at Posing near Pressburg in Hungary, and at Wolfsthal in 

 the county of Stollberg in the Hartz ; also such as contain considerable 

 quantities of it associated with other minerals, at Felsobanya in Upper 

 Hungary, at Crcmnitz, Schemnitz, and other places in Lower Hungary, 

 and in France, Other localities are Br'dunsdorf near Freiberg in Saxo- 

 ny, Neudorf in Anhalt, Cornwall and Scotland. The fibrous variety oc- 

 curs at Loben in the valley of the Levant in Carinthia, and the compact 

 at Magurka in Hungary. 



5. It is used for extracting the crude antimony, or the metal itsef, 

 which is employed in the manufacture of several metallic alloys, and in 

 medicine.

i. Haidingerite. BERTHIER. 



Massive ; sometimes exhibiting appearances of prismatic crys- 

 tals, but generally in confusedly aggregated masses, whose struc- 

 ture is foliated. 



Lustre feeble, metallic. Color iron-grey, with tarnished hues. 

 1. Before the blosv-pipe, it melts readily. It is quickly acted upon by 

 cold muriatic acid, giving out pure sulphuretted hydrogen ; and is total- 

 ly dissolved except some Pyrites and Quartz, 



2. Analysis. 

 By BERTHIER. 



Sulphur 308 



Antimony ..... 52-0 



Iron 16-0 



Zinc 0-3 



3. It occurs along with Quartz, Calcareous Spar and Iron-Pyrites, at 

 Chazellesin France. 



4. It has until lately been rejected as an ore of antimony, on account 

 of the impurity of the metal obtained. 



5. It is probable that this mineral is nothing more than an impure va- 

 riety of Grey Antimony.
