SYNONYMES, AND PRIMARY FORMS. 453 



AMPHIBOLE. 



crystallised. An oblique rhombic prism , P on M or M' 3 



103 15'; M on M', 124 30'. 

 fibrous, 

 amorphous. 



The following varieties appear, from the measure- 

 ment of their angles, to belong to this species. 

 Common Hornblende, colour dark green or greenish 



black; Keniphyllite ; Keratophyllite. 

 Carinthin, in colourless, yellowish, and greenish crys- 

 tals. 



Basaltic Hornblende. 

 The foliated Augite of Werner. 

 The blue Hyperstene of Giesecke. 

 The green Diallage of Haiiy ; Smaragdite ; Lotalite. 

 Pargasite, in short green crystals. 

 Actynolite; Actiuote; Strahlite ; the crystals green, 



slender, and sometimes radiating. 



Tremolite ; Grammatite ; the crystals colourless or 

 green, or pink, or brownish and generally imbedded 

 in Dolomite; frequently fibrous; and sometimes ra- 

 diated. 



A transparent and colourless variety occurs with 

 the white Pyroxene at New York. 



Several specimens sent me as white pyroxene were 

 all amphibole except one, which contained two or 

 three imbedded crystals of pyroxene. 

 Amianthoide ; Amianthinite ; Asbestiiiite ; Byssolite ; 

 two separate fibres of this substance have afforded 

 the measurement of 124 30.' 

 Amphigene, see Leucite. 

 ANALCIME ; Cubicite. A cube. 

 the crystals red ; Sarcolite. 

 Anatase, see Titanium, oxide. 

 ANDALUSITE; Micaphyllite ; Stanzaite. A right rhombic 



prism, M on M', 91 20', as measured by W. P. 

 Andreasbergolite, see Harmotome. 

 Anhydrite, see Lime, sulphate, anhydrous. 

 ANTHOPHYLLITE. Cleavage parallel to the lateral planes of 

 a rhombic prism of 125, and to both its diagonals ; and 

 another cleavage apparently perpendicular to the axis 

 of the prism. The bright plane which is generally 

 visible in the specimens, is parallel to the greater 

 diagonal of the prism. 

 Anthracite, see Coal.
