The agreement is very satisfactory at the beginning, 

 if we consider that the errors of observation are rather 

 large. This method gives a direct determination of the 

 destruction, and not an indirect one, as do the measure- 

 ments of the electrical conductivity. 



The destruction of rennet increases very rapidly with 

 increasing temperature, as is shown by the following table :
