The hemoglobin-bearing cells are undergoing more or less continual disintegration in health as well as in disease. The characteristic ferruginous compound thus is markedly altered or destroyed. A number of products of such disintegration or change have become familiar, but their precise origin and their ultimate fate continue to be a matter of speculation.
