During the 12-vear survey, counts were done

Differential counts showed neutrophils and lymphocytes to have very nearly the same meanlevel

years. Graphic treatmentof these elementsis presented in Figures 49 through 54. Thesimilarity of
counts between the two groupsis probably best
seen in the cumulative percentdistribution curves
(Figure 55). The levels of eosinophils, monocytes,
and basophils were not remarkably different between the exposed and unexposed groups and
were similar to the levels in past surveys.
