464 LIST OF MINERALS, THEIR 



Crichtonite, see Titanium. 



Crispite, see Titanium, Rutile. 



Crocalite, see Mesotype, red, globular radiated. 



CRUNSTEDIT, is said by Leonhard to crystallise in hexagonal 



prisms. 



Crucite, see Chiastolite. 

 CRYOLITE. Cleavage parallel to the planes of a square or 



rectangular prism. 

 Cubicite, see Analcime. 

 CYANITE ; Disthene ; Kyanite ; Rhetizite ; Sappare. A 



doubly oblique prism, P onM, 93 15'; P onT, 100 50'; 



M on T, 106 15', measured by W. P. on cleavage 



planes. 

 Cymophane, see Chrysoberil.

Datholite, see Lime, borate, siliceous. 

 Daurite, see Tourmaline, red. 

 Dapeche, see Bitumen. 

 Delphinite, see Epidote. 

 Deodalite, see Pitchstone. 

 DESMINE. 



Devonite, see Alumine phosphate. 

 Diallage. 



geeen, see Amphibole. 



metalloide, foliated, see Schiller spar. 



fibrous, see Bronzite. 

 Dialogite, see Manganese, carbonate. 

 DIAMOND. A regular octahedron. 

 Diaspore, see Alumine, hydrate. 

 DiciiRoiTi:; Cordierite; Jolite ; Peliome ; Steinheilite. 



crystallised. A regular hexagonal prism. M on a 

 plane of mod. c, 137 46', as measured by W. P. 

 Diopside, see Pyroxene. 

 Dioptase, see Copper, carbonate, siliceous. 

 DIPYRE; Leucolite. From a very minute crystal in my 



possession, I suppose the primary form to be a regular 



hexagonal prism, but the planes are too imperfect to 



determine this point by measurement. 

 Disthene, see Cyanite. 

 Dolomite, see Lime, carbonate, magnesian. 

 Dragonite, see Quartz, crystallised. 

 Dysodile, see Coal.
