lyophilized, and tritium in the water portion was
counted in a Nuclear-Chicagoliquid scintillation
counter. From these values of total body water,
fat was estimated by the formula % fat =100
—(% TBW/0.72). The % TBW is total body
water (in kg) as percent of gross weight. Lean
body mass (LBM) was taken as the difference between gross weight and fat (kg).
The data are shown in Table 20. According to

Siri (personal communication) the valuesfor total
body water, fat, or lean body mass are not different from averages for Caucasian subjects in the
San Francisco area. Figure 52 showsthe values of
blood volume(liters} and red cell volume (liters)
plotted against total body water. Regression lines
drawn for Caucasians by Moore'’ and Siri (un-
published) disclose that with the exception of one
case the values of Marshallese fall far below those
described by the authors. The average red cell
