LOGARITHMIC ORDER OF DEATH 



TABLE 7 



Death rate constants at successive time intervals for various 

 organisms killed by heat or by poisons. (The original values of the 

 death rate constants K are multiplied by 1000.)

liibit the increasing mortality rate with the progress of 

 time which has been observed by Levine and his asso- 

 ciates for spores. In our experiments, values for K (the 

 coefficient for the rate of reduction per unit of time)
