Valves for both sexes are grouped for neutrophils and lymphocytes. Detailed annual observations, including blood cell counts, on the Utirik population did not begin until 1973. Leukocyte differentials and platelet counts were not obtained for six and five of the examination years, respectively, but for graphing purposes the 100% line has not been broken at those years. 9
