INFLUENCE OF TEMPERATURE 51 



serum, the spontaneous decomposition of vibriolysin 

 and the coagulation (by heat) of haemoglobin, which 

 process may also be regarded as due to a spon- 

 taneous decomposition (with hydration), the value 

 (log K t log K ) as a function of temperature may 

 be represented by a straight line. In these cases 

 the observed interval of temperature is only about

9 C. or less. In the next diagram (Fig. 10) the 

 range of temperature is greater, 2O-3O C. Here 

 the straight line does not fit so well ; the general 

 formula given above represents the observations 

 better. The values calculated from this formula 

 are given by the lines drawn in the diagram. These 

 are dotted for the heterogeneous systems, which 

 behave just as the homogeneous ones.
