quiet on the bottom (not to mention an occasional movement) and 
breathing calmly. The duration of the experiments varied; the values 
of table I refer only to those cases when the animal after the experi¬ 
ment behaved quite normally. For in too long continued experiments 
asphyxiation sets in and the 0 2 value becomes too small.

From the publications of Montuori x ), who in different fishes stated 
the diminution of the 0 2 consumption with the temperature of the 
water, I borrow the following scattered figures t*bout Scyllium canicula. 
If from these observations the consumption per M* is calculated 
for the same temperature, we find:
