A comprehensive study of this method has been made by ROBERT OLESEN, Of the U. S. Public Health Service" (Pub. Health Rep., I927, 42, x355-I367). The physiological requirements of man are satisfied by o.oI milligram of iodine daily. When the water supply contains 5 or more parts of iodine, calculated as sodium iodide, per i,ooo,ooo,ooo, the iodine supply of a region is ample. When the iodine supply is deficient, the deficiency may be overcome by addition of minute amounts of sodium iodide to the water supply. This salt readily dissolves in the water. The addition may be made daily, or less frequently. The dosage, naturally, is governed by its frequency. At the present time, iodization of the drinking water is practised in Rochester, N. Y., and Anaconda, Mont., and in Ilkeston and Heanor, England. It has been practised in Sault Ste. Marie, Mich., and Virginia, Minn. From his study of the subject, Olesen concludes that, while iodization cannot be recommended for wider use until stronger evidence concerning its value is forthcoming, nevertheless. iodized water should not be condemned as worthless.
