 centres. Inclination of r on T = 128 20', 

 of Mon T= 116 40', nearly, BREWSTER. 



Lustre vitreous. Colour carmine-red and pale 

 straw-yellow, in two different directions, perpen- 

 dicular to each other, and to the lengthened 

 prisms. Streak white. Translucent. 



Brittle. Hardness = 6-0 ... C-5. Sp. Gr. = 3-137, 

 TURNER. 



Before the blowpipe it intumesces, but fuses only with 

 difficulty into a dark greenish-grey scoria. Salt of phos- 

 phorus dissolves it with effervescence into a globule, which 

 contains a skeleton of silica, and becomes opake on cooling 

 It shews nearly the same reactions as the Epidote from 

 Arendal, with which it likewise agrees in most of its other 

 properties. This mineral is named in compliment to Mr 

 WITHABI, who discovered it in Gleucoe in Scotland, in a 

 reddish trap-rock.
