which means that the rate is a logarithmic function of the reciprocal 

 of temperature, or the logarithm of the rate is a linear function of 

 the reciprocal of temperature. Fig. 14 shows the rate of alcoholic 



fermentation to be a simple logarithmic function of -^^ according to 

 data by Aberson (1903).

In biological literature, the statement is frequently- 

 found that biochemical processes of organisms, such 

 as motility, respiration, growth, etc., follow the same 

 temperature laws as chemical processes. This state- 

 ment has its very great limitations as the following 

 reasoning will readily show: Strept. thermophilus will
