Since parenteral therapy with properly calculated dosage of iron-dextran complex should be discontinued when a hematological response has been obtained, as well as when this type of therapy fails or the patient eventually becomes anemic, iron-storage diseases, i. e., hemosiderosis or hemochromatosis, should not occur under these circumstances, because the possibility of iron overload is eliminated. The subject of iron-overload has been discussed in a textbook, "Iron in Clinical Medicine" (edited by Wallerstein and Mettier, Berkeley, University of California Press, 1958). The question of whether hemosiderosis progresses to hemochromatosis has been answered both affirmatively and negatively. Much
