BB melts with intumescence, and becomes 

 phosphorescent. 



Readily decomposed by muriatic acid, 

 the silica being separated in the form of a 

 viscid powder. 



Localities. — Scotch. Campsie Hills, Stir- 

 lingshire, in very fine brick-red crystals, as- 

 sociated with Quartz, Chlorite and Calcite. 

 Long Craig, Dumbarton Muir, in led crystals. 

 Ballygroggan, near the Mull of Cantyre, in 

 large red crystals. In small bright yellow 

 crystals in a vein of Calc Spar, traversing 

 Serpentine, at the south end of Balta Island, 

 one of the Shetlands. Irish. — The Giant's.
