200 KARABfi DE SODOME 



Localiti/. Altenberg, near Aix-la-Chapelle. 



The proportion of iron being very vari- 

 able, Monlieim, who has analysed several 

 specimens of this mineral, does 'not consider 

 it to be a distinct species, and proposes the 

 name Ferruginous Zinc-spar for the light- 

 green varieties, which contain a large amount 

 of zinc ; and Zinc-iron Spar for the dark- 

 green varieties, and those which become 

 brown by the oxidation of the iron.

BB gives off fumes of sulphurous acid, 

 and a grey slag, with a globule of bismuth. 



Name. After Mr. Karelin, by whom it 

 was brought from Siberia.

BB intumesces and fuses readily to a 

 black shining slag. With borax yields an 

 iron-coloured glass, which, in the inner 

 flame, becomes blood -red. 



Soluble in muriatic acid. 



Locality. Buon, about 1^ mile from 

 Arendal, in Norway, in a felspathic rock.

Kenngottite. a mineral somewhat re- 

 sembling Miargyrite, but containing a larger 

 amount of silver. It is found in irregularly 

 grouped crystals, of an iron-black, to a lead- 

 grey colour, at Felsobanya, in Hungary. 



Name. After Kenngott, Professor of 

 mineralogy at Zurich. 



Keramohalite, J. Jurashy. A mineral 

 with the same composition as Alunogen, oc- 

 curring in crystalline crusts, and also in 

 six-sided tables, with Iron Vitriol, near 

 Konigsberg, in Hungary. Oblique. S.G. 

 1-6 to 1-7.

 Kerargyre, Beudant; Kerargyrite, 

 Dana. Oblique: primary form the cube- 

 Occurs crystallized in small cubes and acicu- 

 lar prisms, generally massive, and looking 

 like wax; sometimes columnar; often in 

 crusts, investing other substances. Colour 

 most frequently pearl-grey, sometimes green- 

 ish or violet-blue. Acquires a brownish 

 tarnish on exposure.. Feebly translucent or 

 opaque. Lustre resinous. Yields to the 

 nail, and is malleable and sectile. Streak 

 white and shining. No cleavage. Fracture 

 imperfect flat-conchoidal. II. 1 to 1-5. S,G» 

 5-562.

Comp. Protochloride of silver, or Ag, CI = 

 silver 75-3, chlorine 24-7 = 100. 



BB on charcoal yields metallic silver, 

 with evolution of an odour of muriatic acid. 

 Rubbed on a plate of mcustened iron, the 

 surface becomes covered with a thin film of 

 metallic silver ; on the addition of oxide o*" 

 copper, the flame becomes blue.
