The specificity of liver extract in the pernicious or hyperchromic anemia of pregnancy and of large doses of iron in the secondary or hypochromic type of anemia of pregnancy has greatly increased the interest in this subject and in the deficiency factors in anemia in general. The high incidence of some degree of anemia in pregnancy, when looked for, and the demonstration of food deficiency factors in its etiology also establish the great preventive opportunity in prenatal and health examination work. It has been stated that, next to the urine and blood pressure, a blood count is of the greatest importance during pregnancy. The pernicious form of the anemia, untreated, has had a 65 per cent mortality. In none of 500 cases on record had prenatal care been given. The secondary form of pregnancy anemia, by lowering of resistance, may dispose to a variety of obstetric complications and infections. THE
