Fig. 23. — Temperature coefficients of growth of Bacterium coli (upper curve) 

 and of B. ramosus (lower curve). 



The following table shows the generation times and 

 temperature coefficients of five bacteria at the time of 

 most rapid growth, after Max Muller (1903). The 

 detailed data for Bacterium A will be found in Table 

 48, p. 194. The temperature coefficient is quite evidently 

 not constant, but decreases with increasing temperature. 

 To emphasize this decrease of the temperature coefficient
