MICA. The crystalline form of the brpwn Mica from Vesu- 

 vius is an oblique rhombic prism, P on M or M', 98 40'; 

 M on M', 100, as determined by W. P, from measure- 

 ment of some brilliant crystals. From the analyses of 

 different substances which have been denominated Mica, 

 it appears probable that different species of minerals 

 have been comprehended under that name, and that 

 among these there may be different crystalline forms. 

 One of these varieties appears, from the direction of 

 some of its cleavages, to crystalline in right prisms, 

 which are probably hexagonal. 

 Micaphyllite, see Andalusite.
