During the past two decades, iodine in its relation to the thyroid gland and to the prevention and cure of goiter has been a subject of renewed interest and investigation. The work, especially that of Marine and his associates,1 has demonstrated that simple goiter can be prevented, and has stimulated the undertaking of thyroid surveys in many parts of the world.
Marine2 states that goiter is a term used to describe all thyroid enlargements in animals as well as in man. Although the ultimate cause of thyroid enlargement is still unknown, it is immediately dependent on a relative or absolute deficiency of iodine in the thyroid gland—iodine hunger.
