Comments. Phe peripheral levels of blood clenents have shown considerable Mluctuation fron
vear to year, The explanation is not known, One
night speculate that, since upper respiratory and
gastrointestinal tatections are coramon, the tenipotal relationship of the hematolugical examinauions
to periods of bacterial infection might strongly tnfluence the general level of certain elements, par-
ticularly the leukocytes. ftas not knowa whether
the drup in 1960 leukocyte levels was so tntleaenced. As pointed out, the rnfluenza epidemic in
carly L960 apparently spared Rongelap Atoll.
Since hematological examinations were uot done
