All counting was done with an Anton end-window: geiger tube,

RESULTS AND DISCUSSION
The ratio of wet to dry weight and the fat content of the liver samples
are presented in Table 1.
The fat constituted an average of 47 percent by
weight on a wet basis with a standard deviation of 9.71, and 74 percent by
weight on a dry weight basis with a standard deviation of 9.29.
