Great River, South Africa, &c. 
(Cases 39 and 40*) contain the different va¬ 
rieties of compact red iron-stone and red hema¬ 
tite , and of hydrous oocides of iron , the latter, com¬ 
prehending Werner’s ochrey and compact brown

several varieties of argillaceous or clay iron-stone , 
such as common, columnar, pisiform, reniform 
clay iron-stone, meadow-ore, &c.—Salts of iron ; 
viz. carbonate of iron , or spathose iron ore, the 
primitive form of which is different from that of 
carbonate of lime : crystallized, massive, and 
botryoidal ( sphaerosiderite of Hausmann) in ba¬ 
salt.— Arseniate of iron, or pharmacosiderite, 
which occurs only crystallized, chiefly in cubes, 
whence Werner’s name of cube ore. [See Bri¬ 
tish Collection: Cornwall.]— 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.—The pyrosma- 
lite considered by some as a muriate of iron.— 
Phosphate of iron , 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
