BB fuses, with diflicnlty, at the edges to 

 a black mass ; with borax yields a pearl 

 which is yellow in the outer flame, and be- 

 comes colourless on cooling. 



Locality. The Ozark Mountains, Magnet 

 Cove, Arkansas, U. S., in small masses, Avith 

 Elasolite and Brookite. 



Name. From Schorl, and oiu,oioi, like, from 

 its resemblance to Schorl in colour, fracture, 

 and crystallization.
