Specific gravity of vapor, ST. 371. History.—Iodine was discovered in 1811 by , a chemical manufacturer of Paris. He noticed that a dark-colored liquor, left after the preparation of sodafrom the ashes of sea-weeds, powerfully corroded his kettles, and that whensulphuric acid was added to the liquor, a brown substance separated, whichon the application of heat was converted into a violet-colored vapor. A sub-sequent examination showed that the substance in question was a new cle-ment—Iodine. ***. Natural History —Iodine is widely, but sparingly distributedin nature. In the inorganic kingdom it is a constituent of all sea-water, ofmany mineral springs (Saratoga, Carlsbad, etc.), and also of certain rare min-erals. In the organic kingdom, it exists probably in all marine plants, but Qx
