Anhalt. The fibrous variety occurs at Loben in the valley 

 of the Lavant in Carinthia, in beds of brachytypous Pa* 

 rachrose-baryte, and the compact one particularly at Ma- 

 gurka in Hungary. 



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

 metal itself, which is employed in the manufacture of se- 

 veral metallic alloys, and in medicine. 



3. AXOTOMOUS ANTIMONY-GLANCE. 



Prismatoidal Antimony-Glance, or Grey Antimony (in 

 part). JAM. Syst. Vol. III. p. 390. Man. p. 285. 



Fundamental form. Scalene four-sided pyramid. 

 Vol. I. Fig. 9. 



Simple forms. P + oo = 10120' (nearly) ; Pr-f oo. 



Combinations, "of the preceding forms, their ter- 

 minations not observed. 



Cleavage, P oo highly perfect ; less distinct, 

 though easily observed, when the crystals are not 

 too small, P -f oo and Pr -f- oo. Fracture not 

 observable. 



Lustre metallic. Colour steel-grey. Streak un- 

 changed. 



Sectile. Hardness = 2-0 ... 2-5. Sp. Gr. = 5-564. 

 Compound Varieties. Massive : composition co- 

 lumnar, individuals generally very delicate ; straight 



and parallel, or divergent. 



OBSERVATIONS. 



1. Nothing as yet is known of the proportions among the 

 ingredients of the present species. It contains sulphur, an- 

 timony, and lead. 



2. The axotomous Antimony-glance seems to be a rare 

 mineral, or at least not sufficiently attended to by mine-
