with the presence of thermal or other . yuries

Marshallese counts remained at similar levels.
The neutrophile count in both the Japanese
gest the early blood response and prolonged
recovery of the Japanese was similar to that
white count. The lymphocyte count in both
groups was depressed early and remained de-

From the 6th week until the termi-

the Japanese for weeks lz to 15 must be sus-
pected of being high for the reasons given
earlier.
Various characteristics of the Japanese

The present findings in the Marshallese are
a) total white cell and neutrophile counts
showed no definite minimum at 4 weeks as evidenced in Japanese groups A to D, but rather
fluctuated during the first weeks with minimum
Ineap counts occurring in the 6th week or later,
b) neutrophile counts were unstable over the
first 5 weeks, and recovery to control levels was
not complete by the 6th month, c) lymphocyte
counts remained depressed throughout the period of observation.
Platelet data in the Japanese are not suffment to allow more than rough qualitative
comparisons, This is nn fortunate since changes
