Protein in blank = 1,126 milligrams. 



The results of a series of digestions run at 30" are shown in 

 Table XXIII. 



The results of a series of digestions run at 40" are shown in 

 Table XXIV. 



The results of a series of digestions run at 50° are shown in 

 Table XXV. 



The values obtained closely approximate those given in Table 

 XXIV. There appears to be very little difference in the rate of 

 digestion in the neighborhood of 40"^ to 50^.
