in the females. For the other organs the range 
of V is from 10 to 17. 
For the intervals the difference seems to be 
somewhat more marked, the values of V being 
greater in the female series. However, the small 
number of females influences the value of o-. 
Furthermore, the quotient D/ <r D is never higher 
than 2.3. This figure is found for the variability 
of Cs (the distance from the left kidney to the 
cloaca) in both sexes. 
CORRELATIONS: The length of tail has al- 
ready been discussed above (Table 4). The 
coefficient of correlation is of the same value 
in the two sexes. Supporting figures are given in 
Table 12, both for the symbol r and for its 
transposition in Z. 
The correlation between the length of the 
body and the weight of the animals seems to 
be low in the male group. The average weight 
is of nearly the same value in both sexes. There
