CHLORIDE OE IRON.—Earthy. Dull. Brownish-red. Deliquesces when exposed to the air. Sublimes before the blowpipe. Easily soluble in water and in alcohol. i*e 2 ci 3 , chlorine 65*02, iron 34*98. Is found as a sublimate investing other minerals on Vesuvius and in Iceland. CHLORIDE OE VANADIUM.—The only notice we have of this mineral is in a letter from Del Rio, of April, 1837, in which he states that he had named it zimapanio, and that when he first saw it he supposed it to be a reddish- brown ferruginous clay, which it much resembles. W11other it is chloride of vanadium or not, the editors cannot say. It occurs as a thin earthy coating on crystals of vanadiate of lead, and is disseminated in small quantities through the matrix which accompanies the vanadiate. DELVAUXINE. — Amorphous.
