Abstract
OF the two aspects of iodine and its chemistry which are here surveyed, the first is that of the part played by the element in terrestrial economy, whether inorganic or organic or both. In the total make-up of the earth, iodine is not one of the fourteen elements which compose 99·95 per cent of the mass, but is one of the rarest of the non-metallic elements. Nevertheless, it is scattered almost everywhere, in minute traces ; a ton of average rock contains some 300 milligrams, a ton of sea water about 17 milligrams.
