What's the difference between hematite and hepatite?
Hematite
Definition:
(n.) An important ore of iron, the sesquioxide, so called because of the red color of the powder. It occurs in splendent rhombohedral crystals, and in massive and earthy forms; -- the last called red ocher. Called also specular iron, oligist iron, rhombohedral iron ore, and bloodstone. See Brown hematite, under Brown.

Hepatite
Definition:
(n.) A variety of barite emitting a fetid odor when rubbed or heated.
