Quisumbing: Determination of Glucose and Starch 591 
of oxidation of glucose, using 0.1 N alkaline potassium perman- 
ganate solution. The total number of cubic centimeters of 0.1 
N potassium permanganate used for oxidation was obtained by 
heating the alkaline potassium permanganate mixtures of the 
same composition to different temperatures, and. for different 
lengths of time after 95° C. had been reached. The results are 
given in Tables 2, 3, and 4. 
Table 2. — Glucose oxidation by potassium permanganate at various tenv- 
peratures rising from 29° to 95° C. in four minutes. 
[For final volume of mixture of 60 cubic centimeters.] 
Table 3 . — Glucose oxidation by potassium permanganate at various tem- 
peratures rising from 29° to 95° C. in two minutes. 
[For final volume of mixture of 60 cubic centimeters.] 
Length of time after 95° C. had been reached.
