AR'SF.NIC, J. [ aj'enicum , Lat. of a> c g, Gr. man, or

name of arfenic, is a metallic calx, of a glittering white- 
nefs, fometimes of a vitreous appearance; exciting an 
impreflion of an acrid tafte on the tongue ; volatile rvhen 
expofed to fire, in which lituation it rifes in the form of 
a white fume, with a very evident fmell of garlic. But 
although it is mod commonly met witli under this form, 
it may be reduced to the metallic (late by treating it with 
oils, foaps, or charcoal, in clofed veflels. It is fometimes 
found native in flaladtites, or in protuberant depolitions, 
formed of layers more or lefs diftindft and concentric, which 
are feparable from each other like the coats of an onion, 
or the laminae of (hells, from which it has obtained the 
name of teftaceous arfenic. In other inftances the mafles 
are formed of very fmall feales; which renders the fur- 
face of the fpecimen fometimes granulated, and fometimes 
full of fmall cavities: it is then called fcaly arfenic. It 
is alfo found in friable mafles, poflelfing fcarcely any con- 
liflence. It thefe various forms we receive it from Bohe¬ 
mia, Hungary, Saxony, Saint Marie aux Mines, &c. 
Arlenic appears to exift in the metallic Hate in its com¬ 
binations with cobalt in the teflaceous cobalt ore, or with 
iron in milpickel. It is often combined with metals in va-
