different varieties of compact red iron stone , and 
of red hematite. 
(Case 39-) Ores of iron continued :— hydrous 
oxides of iron, comprehending Werner’s ochrey 
and compact brown iron stone, and brown hema¬ 
tite,together with several varieties of argillaceous 
or clay iron stone, such as common, columnar, 
pisiform, reniform clay iron stone, meadow ore, 
&c .—Carbonate of iron, or spathose iron ore, the 
primitive form of which has lately been ascertain¬ 
ed, by Dr. Wollaston, to be different from that of 
carbonate of lime : crystallized, massive, in com¬ 
bination with other substances. 
(Case 40.) Contains the remaining ores of iron 
and those of manganese, a metal which stands in 
close geognostical relation with iron.— Arseniate of 
iron, which occurs only crystallized, chiefly in 
cubes, whence Werner’s name of cube ore.— 
Chromate of iron, among the specimens of which 
is one from Baltimore, in which this substance is 
intermixed with talc coloured purple by chromic 
acid.— Muriate of iron, called pyrosmalite, from 
Sweden— Phosphate of iron, crystallized, massive, 
and pulverulent: among the specimens of the lat¬ 
ter, are, the masssive variety from New Jersey, 
and several earthy varieties, in clay, wood, peat, 
&c.—The pitchy iron ore of Werner, from Li¬ 
moges, may be referred to phosphate of manga, 
nese.— Ores of manganese :—radiated grey manga¬ 
nese, from Ihlefeld, &c. some varieties of which
