Table 5. — An Aurellia aurita at Tortugas, Florida, warmed from 27.3° to 36.4° C. 



The parabola y = o.o865a(;2 fits the observed facts fairly well. 



Similarly, table 5 and figure 7 show the decline in rate displayed by a 

 specimen of Aurellia aurita, from Tortugas, which was heated from 27.3® 

 to 36.4° C, and the actual conditions are fairly well represented by the curve 

 y = 0•5I5^^ showing that in heating the rate declines about 6 times as
