AQ LORS May 24, 1966 Leo M. Meyer, M.D. The Long Island Jewish Hospital Queens Hospital Center Affiliation §2-68 16hth Street Jamaica, New York 11432 Dear Leo: The results of our assays of tritium and estimates of total taady water (TSW) in your subjects are enclosed. In addition to tabulating the data, we have plotted your blood volumes and red cell volumes againat TBW. The dashed and solid lines on the chart are regression lines that Francis Moore and I independently derived from our own normal subjects. About half of your subjects are clustered about my "normal" regression line. The other half lie significantly below the lines because of relatively emall red cell volumes, Plasma volumes appear to lie within the range of my normal values. Sincerely, William E.
