“…Anaemia was constant; it was usually moderate, but in twelve cases the erythrocytes fell below one million per c.mm. In a few cases, as described by Segar and Stoeffler (1932), Bonar and Smith (1933), Abbott andAbbott (1935), andBernheim-Karrer (1936-7), the erythrocytes in the first days of life were over four million per c.mm., and this slight anaemia was unaccompanied by excess of erythroblasts in the blood, but later became severe. Erythroblasts were usually present, and occasionally in large numbers.…”
