DOMAIN X. TRANSILIENT. 



almost metallic, this effect is produced by a thin 

 coating of talc, which covers the fibres of the 

 stone. 



" The cross fracture is extremely unequal and 

 splintry, with a mixture of spangles of a differ- 

 ent sqbstance. This stone is translucent on the 

 edges, to the thickness of four lines, and so soft 

 as to be scratched with the nail, the streak being 

 whitish and of some lustre : it faintly stains cloth 

 with a grey line, is a little flexible, and pretty 

 heavy. Under the blow-pipe it melts into a black 

 globule, not exceeding the tenth part of a line. 



" It is then evidently an intermediate kind be~ 

 tween talc, steatite, and asbestos. 



" The long fibres are intermingled with pris- 

 matic columns, striated lengthwise, white, la 

 minar, very brilliant, but of which I do not 

 know the nature. They are soft, translucent, 

 and soluble in nitrous acid ; but without effer- 

 vescence, and in length of time. They do not 

 crackle under the blow-pipe ; and on charcoal 

 turn brown without melting. They can only 

 be melted on a point of sappare, into brown 

 brilliant glass, without bubbles, and half trans~ 

 parent ; the drop not exceeding the tenth part of 

 a line. This stone is found at Weysler Stoude."*
