What does the word iodine mean?

-
It is contained in the mother waters of certain fuci, and is obtained by pouring an excess of concentrated sulphuric acid on the water obtained by burning different fuci, lixiviating the ashes and concentrating the liquor. The mixture is placed in a retort to which a receiver is attached, and is boiled. The iodine passes over and is condensed. It is solid, in the form of plates; of a bluish gray colour, of a metallic brightness, and smell similar to that of the chloride of sulphur. Its s. g. is 4. 946. When heated, it becomes volatilized, and affords the vapour which characterizes it. With oxygen it forms Iodic acid, and with hydrogen Hydriodic acid. The tincture of iodine and the iodides have been employed with great success in the treatment of goitre and of some scrofulous affections. It must be administered in a very small dose and for a long period. It is said to be apt, however, to induce cholera morbus, signs of great nervous irritability, and emaciation of the mammae. When these symptoms, collectively termed I'odism, Iodo'sis, and Iodin'ia, are urgent, the dose may be diminished, or it may be wholly discontinued, and afterwards resumed. Various preparations of iodine are employed in medicine.
