Cleavage distinct, parallel to p and t. 



Fracture imperfectly conchoid al. 



Lustre vitreous. Color black, often greenish ; 

 splinters are faintly translucent, and of a green color, per-, 

 pendicular to p, of a brown color parallel to it. In large 

 crystals, it appears opake. 



Hardness = 5*5 . . . 6-0. 



1. According to Mr. CHILDREN, it is composed of silica, iron, man- 

 ganese and lime, with a trace of titanium. 



2. It occurs at Arendal in Norway, in small crystals, (resembling dark 

 colored crystals of Pyroxene,) disposed on the surface of crystals of Albite ; 

 and at Governeur, (N.Y.) coating crystals of Feldspar.
