(Plate xv., tig. 4.) 



A single specimen consisting of a large number of small, 

 green, transparent crystals about 1*5 mm. in length, associated 

 with massive cuprite is in our collection. Two crystals were 

 measured, and yielded the forms enumerated below; in addition 

 k (130) and I (230) are doubtfully present. Because of the 

 striated nature of the prism faces accurate centering is difficult 

 and the measurements are not good.
