 Upon ignited charcoal, or before the blowpipe, it emits a 

 strong garlick smell, and copious white fumes, and at last 

 disappears altogether. It is the volatilized metal, and not 

 the white fumes of arsenious acid, which possess that odour. 



2. It is most generally found in veins, seldom in beds, 

 and is accompanied by hemi-prismatic Sulphur, rhombohe- 

 dral Ruby-blende, and various species of the orders Metal, 

 Pyrites, Glance, &c. Rarely it is met with along with 

 hexahedral Gold and prismatic Tellurium-glance. 



3. Native Arsenic is not uncommon in several of the 

 mines of Annaberg, Schneeberg, Marienberg, and Frei- 

 berg in Saxony ; it occurs at Joachimsthal in Bohemia, 

 at Andreasberg in the Hartz, in the Black Forest, in Al- 

 sace, at Allemont in Dauphiny, at Kongsberg in Norway, 

 at Kapnik in Translyvania, and in beds at Orawitza in 

 the Bannat of Temeswar. 



4. It is variously employed in metallurgical processes, it 

 enters into the composition of certain kinds of glass and of 

 many colours, and has been introduced even among the 

 pharmaceutical preparations. It is a violent poison.
