 filver, in mafles, or diileminated, fometimtis ftaladlitical or

 mids, or radiated in a llellate manner : jt diiFtrs much in 

 degree of tranfparency, colour, texture, and form : it is 

 iriable or brittle, but (o foft as to be cut with a knife: when 

 broken it has a glaiTy appearance, and when fcraped with a 

 knife the particles appear fcarlet : texture flat conchoidal, or 

 approaching to the foliated : when heated it crackles, and 

 melts yery eafily before the blowpipe, blackening, burning 

 with a blue flame, and giving out a white fmoke with a 

 flight fmell of garlic: it becomes e^edlric by friction, but 

 only when infuUted j and is foluble in nitric scid without 

 efi^ervcfcence : it detonates with nitre when thrown into a 

 red hot crucible, and becomes then capillary fi'.ver: fpecific

 generally imbedded in quartz and other minerals : it contains 

 generally about jq percent, of fiiver, the remainder being 

 iTiude up of fulphur, arfenic, copper, and iron in various 

 proportions: when Icraped it exhibits a brighter furface but 

 pf the fame colour; it breaks into indeterminate fragments, 

 and is of a fiat texture: it is generally found of a common 

 lorm, rarely cryftallized ; is brittle, but fo foft as to be cut
