LEELITE. 119 



Tetarto-prismatic. Crystallised and massive. 

 Cleavage in three directions, intersecting each other 



at angles of 98 30 7 , 91, and 93 30'. 

 Colour pale red. Hardness, between 5-0 and 6-0. 



Sp. Gr. = 2-8, BROOKE ; = 2 720, GMELIN. 



According to CHILDREN, it fuses before the blowpipe in 

 the platina forceps into a white enamel. With borax it 

 yields a globule, pale amethyst red in the oxidating flame, 

 and colourless in the reducing one. With salt of phospho- 

 rus, a globule with a silica skeleton is obtained, yellow in 

 the oxidating flame, and becoming opake on cooling, trans- 

 parent in the reducing flame. Professor GMELIN of Tu- 

 bingen obtained from two analyses, one of them with car- 

 bonate of baryta, the other with carbonate of soda, the fol- 

 lowing results :
