||Primary source abstract:"This study was designed to examine the validity of a new gas dilution method (GD) for measuring human body volume and to compare its accuracy with the results obtained by the underwater weighing method (UW)." Value is average of the 2 methods (see comments section below)
||P.466 left column 2nd paragraph: "The human body mean volume has been calculated by (primary source) by two different physical methods: the obtained values were 63.83 and 66.61 L. Considering the average value, the
resulting cell number [in the human body] is 1.63×10^13 cells."
