Here there is neither increase in total carbohydrates in the pres- 
ence of peptone, nor is there any change in the reducing power of 
the sugar solutions after boiling with dilute acid. 
Total carbohy- 
drates, moreover, fall a trifle below the percentage of sugar, although 
the difference is within the limits of error. —
