Thus it is in the zone of the a-axis that these crystals 

 display a great richness in forms. At the ends, on the contrary, 

 they often present imperfect crystal boundaries. Sometimes 

 the crystals have been attached at the end , or have been 

 broken. Usually, however, they show a single transverse face, 

 the first pinacoid, which is deeply striated in the vertical direction 

 and is totally lustreless. Beside this face, the prism n and the 

 pyramid p sometimes occur on the edges of the plates (Fig. 7, 

 Plate III). It is the faces of this prism that, by occurring 

 alternately, cause the s triatlon on the first pinacoid a. 



Small, detached epididymite crystals of type II have been 

 found at the locality No. 3 together with catapleiïte, eudidymite, 

 etc. In larger amount, however, and in very large individuals 

 the mineral is met with at the locality No. 2. Here the crystals 

 occur together with iieptunite of type II, parisite, etc. The 

 minerals found here were won by digging in the solid or some- 

 what cracked syenite ground, unfortunately, through the careless- 

 ness of the Greenlanders many fine crystal specimens of epidi- 

 dymite were destroyed, and only a few large individuals were 

 obtained entire and unbroken.
