starvation. Losses in solids, however, are invariably lower than 
those in body weight and water. This shows that starvation 
in the grasshopper results in a rapid loss in water which has a 
decidedly quick and fatal effect. In striking contrast to such 
a condition, Hatai (13), with medusae, and Morgulis {I4), with 
salamanders, find that during starvation the water content is 
increased rather than decreased, but it must be remembered that 
in these cases we are dealing with aquatic forms. Table 5, 
arranged according to body weight, shows that considerable 
variation in the losses for different-sized individuals exists, but 
that after the first twenty-four hours of starvation, larger animals 
tend to suffer the greater relative losses. This is perhaps due 
to the fact that the lighter individuals are still growing, and as 
pointed out by Donaldson (15) in experiments with rats, the 
loss of water in the nervous system of underfed individuals is
