SALOON, lysed ;—the muriate of silver, called also corneous 
Nat. Hist, silver ail'd hom'ore, of various colours, amorphous, 
botryoidal, in laminpe, and cr}'stallized in minute 
cubes and octohedrons ;—the very scarce carbonate 
of silver, also called grey silver ore, from Alt-Wol- 
fach in Suabia, &:c.—In this case begin the nume¬ 
rous copper ores : among the specimens of native 
copper (vAiich, like the native silver, presents a great 
variety of forms, besides the cr^'Stallized, such as 
dendritic,'filiform, &c.) maybe specified the mass 
from Hudson’s Bay, found by Mr. Hearne and de¬ 
scribed by him in his journal. 
(Case 32.) Ores of copper continued; common 
sulphuret of copper or vitreous copper, variously 
crystallized, foliated, compact, &c. To this are also 
commonly referred the oblong, scaly, secondar}^ fos¬ 
sils, knoum by the name of Frankenherg corn ears, 
which occur in the bituminous marl-slate of Fran- 
kenberg in Hessia, and are principally composed of 
vitreous and grey copper.—The variegated copper 
ore, easily known by the reddish colour of its frac¬ 
tured planes, massive and foliated.— Thegreg cop- 
per ore (fahl ore), crystallized, massive, and disse¬ 
minated in various substances. 
(Case 33.) Ores of copper continued: yellow 
copper or copper pyrites, the most common of all 
the ores of this metal: among these is also the pale 
yellow, fine grained variety, called hematitiform 
and blistered copper pyrites.— Red or ruby copper 
ore.
