Abstract 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. SUBJECTS All the subjects lived in or near Portland, Ore., at an elevation of References 1. Mrs. Mable Wilhelm Osgood, Mr. Russell L. Baker and Miss Inez Brownlee collaborated in these studies. 2. Dr. Helen Cary and Dr. Frank Mount cooperated in securing suitable subjects from the schools and orphan asylums. 3. Many reports of so-called normal values have been based on studies of patients with minor illnesses in clinics or hospitals. This practice is to be condemned. It probably accounts for some of the differences between the standards determined by my associates and me and those in general use. 4. Osgood, E. E.; Haskins, H. D.; Trotman, F.

The erythrocyte counts and determination of cell volume were made by Dr. Frank E. Trotman, Mr. Russell L.

Baker and Mr. Howard Johnson. The calculations were all checked several times by Mrs. Mable Wilhelm Osgood, myself and others. 19. Williamson, C.
