(Case 39.) Ores of iron continued:— hydrous 
oxides ofiroii^ comprehending Werner’s ochrey and 
compact brown iron-stone, and brown hematite, to- 
- gether with several varieties of argillaceous or clay 
iron-stone, such as common, columnar, pisiform, 
reniform clay iron-stone, meadow ore, &c.— Carbo¬ 
nate of iron, or spathose iron ore, the primitive 
form' of which has lately been ascertained, by Dr.

i^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. [See 
British Collection: Cornwall]— Chromate of iron, 
among the specimens of which is one from Balti¬ 
more, in which this substance is intermixed with 
talc coloured purple by chromic acid.— Muriate 
of iron, called pyrosmalite, from Sweden.— Phos¬ 
phate of iron, crystallized, massive, and 'pulveru¬ 
lent: among the specimens of the latter are, the 
massive variety from New Jersey, and several earthy 
varieties, in clay, wood, peat, &c.—The pitchy iron 
ore of Werner, from Limoges, may be referred to 
. phosphate of manganese.— Ores of manganese: ra¬
