The following case of anemia in a new-born infant is the sixth to be reported.1 All six cases are characterized by pallor, moderate or severe, noticed within the first twelve days of life. The number of red cells varied from 2,500,000 to 980,000; the hemoglobin content from 48 per cent to 20 per cent; the hemoglobin index from 0.64 to 1.3, and the number of white cells from 10,600 to 68,400. The morphology of the white cells was normal except for an occasional myelocyte. The ratio of lymphocytes to leukocytes was normal, reduced or increased. Myelocytes, though few in number, were seen in most cases. The red cells generally showed achromia, polychromatophilia, anisocytosis and poikilocytosis to a marked or moderate degree. The coagulation time was normal, but the bleeding time was increased slightly in three cases. In two cases the platelet count was reported and was within normal limits,
