492 LIST OF MINERALS, THEIR 



SPINELLANE; Nosin. A rhombic dodecahedron. W. P. 

 SFINKLLE; Ruby. A regular octahedron. 



if black, dark blue, greenish ; Pleonaste. 

 Spinelline, see Titanium, oxide, siliceo-calcareous. 

 Spinthere, see Titanium, oxide, siliceo-calcareous. 

 SPODUMENE; Triphane. Cleavage parallel to the planes, 

 and to both the diagonals, of a rhombic prism of 93" 

 and 87; the bright cleavage plane being parallel to the 

 short diagonal of the prism. No cleavage planes to 

 determine whether the crystal is right or oblique. 



Two substances from the Tyrol have been called 

 Spodumene; one of these resembles the Spodumene 

 from Uto, the other is Zoizite. 

 Spreustein, see Bergmanit. 

 Stahlstein, see Iron, Carbonate. 

 Stanzaite, see Andalusite. 

 Staurolite, see Staurotide. 

 STAUROTIDE; Grenatite ; Staurolite. A right rhombic prism , 



M on M', 129 30'. 

 STEATITE; Speckstein. 



in Pseudomorphous crystals, 

 amorphous. 



Steinheilite, see Dichroite. 

 Steinmark, see Lithomarge, 

 STILBITE. 



foliated, see Heulandite. 



radiated. A right rhombic prism, M on M' 101' 36. 

 This mineral cleaves parallel to the lateral planes 

 of a right rectangular prism, but there is no clea- 

 vage parallel to the terminal planes of Gucha prism. 

 There are, however, in some crystals, indications 

 of cleavage parallel to the planes of a rhombic 

 prism, which have induced me to adopt that as the 

 primary form. 



Stilprio-siderite, see Iron, oxide, hydrous. 

 Stralite, see Amphibole. 



Stromnite, see Strontian, carbonate, barytiferous. 

 STRONTIAN. 

 carbonate. 



crystallised. A right rhombic prism, M on M', 



117^ 32'. 

 fibrous. 



barytiferous ; Stromnite. 

 sulphate ; Celestine. 



crystallised. A right rhombic prism, M on M', 



104". 

 iibrous.
