INJURY, RECOVERY, AND DEATH 



The values of M under these conditions are given in Table 

 III (Curve II). Inspection of the table, and of the curves 

 in Fig. 32, shows that at the higher temperature it re-

Curves II, III and IV are derived from Curve I by assuming that the temperature is raised 

 10 C.; if the two reactions have the temperature coefficient 2 we obtain Curve II; if the 

 coefficients are 1.2 and 2 respectively we obtain Curve III; if the coefficients are 2 aud 1.2 



respectively we obtain Curve IV. 



quires just half as long to produce the same amount of 

 chemical action as at the lower. Hence the consecutive 

 reaction appears to behave in this instance like a 

 simple reaction.
