LiCl and distilled water respectively, since the quantity of water 

 in the former is to the latter as 1 : 1.5. 



While the water content at a given temperature markedly 

 affects the diastase formation, it must be borne in mind that an 

 increase in temperature toward the optimum of diastase forma- 

 tion likewise produces an effect. A closer study of the figures 

 in tables 3, 8, and 4 show that a difference of 0.17% in the amount 

 of water contained in the samples of grains suspended over the 

 solution, 1-3, at temperatures of 15°C. and 25°C. respectively, 

 causes a reduction of the time required for conversion of about 

 1^ hours at the latter temperature. In other words the water 

 content (12.45 grams), table 8, at 15°C. is to the water content 



TABLE 9 

 Quantity of water present at 30°C. in grain used for diastase determination 



(12.53 grams) at 25°C. as 12.45 : 12.53. The diastase from the 

 same samples is as 28 : 26.5. Likewise the water content (15.29 

 grams) above a solution, 1-7, at 25°C, is to the water content 

 (14.95 grams) above distilled water at 10°C. as 15.29 : 14.95. 

 The diastase from the same samples is as 23.75 : 24.25. Al- 

 though the difference in the quantity of water contained in the 

 sample of grains above distilled water at 5°C. and that contained 

 in a sample above a solution, 1-3, at 25°C, is rather wide, the 

 time required for conversion in both cases is approximately the 

 same. That is, the water content (13.41 grams) in the first 

 sample is to the water content (12.53 grams) in the second sam- 

 ple as 13.41 : 12.53 while the diastase from the same two samples 

 is as 26 : 26. The results tend to show that temperature does 

 have an effect on the diastase formation.
