 Wagnerit. FUCHS. Schweiggers Journal. VoL III. p. 269. 



Hemi-prismatic. Horizontal projection of a crystal 

 represented Fig. 197* ; a is not a right angle, 

 b, Jc, and g, if enlarged, would produce parallel 

 edges of combination. 



Lustre vitreous. Colour several shades of yellow, 

 sometimes nearly orange-yellow, often inclining 

 to grey. Streak white. Translucent. 



Hardness = 5-0 ... 5-5. Sp. Gr. = 3-11, FUCHS. 



It has been analysed by FUCHS, who found it to con- 

 sist of 



Phosphoric Acid 41-73. 



Fluoric Acid 6-50. 



Magnesia 4<>-66. 



Oxide of Iron 5-00. 



Oxide of Manganese 0'50. 



The only locality of Wagnerite known at present, is the 

 valley called Hb'llgraben near \Verfen in Salzburg, where 

 it occurs in short and irregular veins of rhombohedral 

 Quartz in clay-slate.

 HOSE, who first ascertained the crystal to which it refers, in 

 the possession of Mr HEULAND, to be "Wagnerite. H.
