SYNONYMES, AND PRIMARY FORMS. 475 



red. 



decomposed. The Atramentstein and Misy, and 

 the red sulphate are, according to Leonhard, 

 related to this species, but their composition 

 is not given, 

 sub-sulphate, resinous ; Pittizite. 



earthy. 



sulphuret ; Iron pyrites, 

 common. 



crystallised. A cube, the modifications of 

 which are frequently defective, and such 

 as might occur if the pentagonal dodeca- 

 hedron were the primary form, 

 auriferous, 

 fibrous. 

 in hexagonal prisms, probably pseudomor- 



phous. 



arsenical ; arsenical Iron ; Mispickel ; Marcasite. 

 crystallised. A right rhombic prism ; M on M ; 



111 12'. 

 amorphous. 



, argentiferous. 



magnetic ; cleavage parallel to the planes of a 



regular hexagonal prism. 

 white. 



crystallised. Aright rhombic priam ; M on M', 



106. 

 scheelate of Iron and Manganese ; Wolfram, 



crystallised. A right oblique-angled prism ; 



M'on T, 117 22' as measured by W. P. 

 fibrous, 

 amorphous, 

 undetermined species, 

 green Iron earth. 



fibrous. 



, containing Lime and Copper ; 



Chalcosiderite. 

 Iserine, see Titanium, oxide, ferriferous. 



K 



Kali, see Potash. 



Kaolin, see Felspar, decomposed. 



KARPHOLITE. Occurs in fibrous crystals radiating from a 



centre, but those which I have seen are too imperfect 



to admit a determination of their forms. 

 Karstenite, see Lime, sulphate, anhydrous.
