 and copper, containing water. 



2. It is very rare, and has been met with only in an abandoned mine 

 at Joachimsthal in Bohemia. 



JURINITE. (See Brookite.)

In imitative shapes, and compact. Fracture conchoidal, to un- 

 even. 



Lustre resinous. Color bluish black. 

 Hardness = 25... 3-0. 

 1. Locality not mentioned. 



KAKOXENE. 



In capillary crystals, and massive, with fine columnar compo- 

 sition, consisting of divergent individuals. 



Lustre silky. Color yellowish, to brown. Streak yellowish.

1. Analysis. 



By STEINMANJV. 



Phosphoric acid 17-36 



Alumina 10-01 



Silica 8-90 



Peroxide of iron 36-82 



Lime 0-15 



Water and fluoric acid 25-95 



2. It is found in the fissures of a variety of Limonite, in the mines of 

 Hrbek, near Zbirow in Bohemia. 



8. It is altogether probable that this mineral is only a variety of Wa- 

 vellite.
