This paper presents a summary of the results of a series of hematologic studies, including all the commonly used procedures, on over 500 healthy persons of both sexes ranging from young children to adults. Details of these studies1 together with reviews of the literature will appear elsewhere. The development of a uniform system of methods for the hematologic study of oxalated venous blood made this investigation possible. These methods are simple enough for routine clinical use, but they approach research methods in accuracy. Erythrocyte counts, hemoglobin values, hemoglobin coefficients and color indexes are reported for 626 persons; cell volumes, volume coefficients and volume and saturation indexes, for 583; reticulocyte counts, for 476; leukocyte and differential counts, for 597, and sedimentation rates, for 853. The ages of the subjects ranged from 4 years to past 30.
