-
A metal of a bluish-gray colour; fibrous texture; brilliant and fine-grained fracture. Specific gravity 7-600 to 7-800; hard, ductile, malleable, and magnetic. The medicinal virtues of iron are tonic; producing fetid eructations, when it takes effect, owing to its meeting with acid in the stomach, which oxidizes it, and causes the evolution of hydrogen gas. When given in the metallic state, the filings are chiefly used; but the oxides and salts are most commonly employed.
