The practice of pediatrics . which there is frequently a chlorotic con-dition of the blood. Pathology.—Cases rarely come to autopsy. Those that do haveusually died of a complicating tuberculosis, ulcer of the stomach, or ofsome other intercurrent affection. The right ventricle is usually dilatedand the left hypertrophied. The blood condition is very characteristic. The hemoglobin is verylow, twenty, thirty, or forty being common finds according to thecustomary von Fleischl scale. In very severe cases it may go even belowthat. The blood as drawn seems almost colorless in these very severecases.

DISEASES OF THE BLOOD §21 that in severe cases the number of red cells may fall to two or threemillion per cubic millimetre. The color index of the cell , however,lowered. The size and shape of the cell are altered and these are moremarked in the severe than in the mild cases. Some of the cells mayhave so little hemoglobin as to look like faint round shadows. Othercells are somewhat smaller than normal and there may be poikilo-cytosis. Normoblasts may be seen sometimes in the severe cases. Theleukocytes are, as a rule, normal, but there may occasionally be a slightleukocytosis. (See Plate XXIV.) Symptomatology.—The symptoms are much like those of a simpleanemia, but there is no emaciation, the well-nourished appearancebeing in striking contrast to the
