SALOON, viz. carbonate of iron^ or spathose iron ore, the 
Nat. Hist, primitive form of which is different from that of 
carbonate of lime: crystallized, massive, and 
botryoidal (sphcerosiderite of Hausmann) in ba¬ 
salt.— Arseniate of iron^ or pbarmacosiderite, 
which occurs only crystallized, chiefly in cubes, 
whence Werner’s name of cube ore. [See Bri¬ 
tish Collection: —Cupriferous arseni¬ 
ate. — Scorodite.—Chromate of iron^ among the 
specimens of which is one from Baltimore, in 
which this substance is intermixed with talc 
stained purple by chromic acid.— pyrosma- 
lite, considered by some as a muriate of iron.— > 
Phosphate ofiron^ crystallized (with native gold, 
from Transylvania), massive and pulverulent: 
among the specimens of the latter are. the mass¬ 
ive variety from New Jersey, and several earthy 
varieties, in clay, wood, peat, &c. To these is 
added the ilvait (the yenite or jenite of some 
mineralogists), which is enumerated by Haiiy 
among the ores of iron, under the appellation of 
fer siliceo-calcaire. 
Case 41. In this and the two following cases 
are contained the ores of lead, the most common 
and useful of which is the sulphuret of lead^ or 
galena; the specimens here deposited include 
various modifications of crystals, detached, and 
grouped together, in combination wdth blende, 
pyrites, and many other substances ; galena of 
various grain, massive and disseminated; galena 
of corroded appeai’ance, decomposed and re¬ 
generated ;
