3. This rare mineral occurs in a bed of gneiss at the copper mine of 

 Nya Bastnaes, near Riddarhyttan, Westmoreland, in Sweden. It is ac- 

 companied by Bismuthine and Mica. 



CHABASIE. Rhombohedral Kou phone-Spar. 

 MOHS. 



Primary form. Rhomboid. P on P = 94 46'. 

 Secondary forms. 



Fig. 127. Fig. 128.

Fig. 127, the primary, having the upper edges and the 

 lateral angles replaced by tangent planes. P on r = 120 

 5'. n on r=143 59'. Fig. 128, the same, in which the 

 edges between P and r are replaced by the planes x. x on 

 a?' = 173 32'. x on x' (over the base) =96 40'. P on 

 = 175 30'. 



Cleavage parallel to the primary rhomboid, but not dis- 

 tinct. Fracture uneven. The faces P are generally stri- 

 ated parallel with the upper edges of the rhomboid.
