TABLE 25. 

 ACID PRODUCTION IN SUGAR BROTHS. 



TABLE 26. 

 CORRELATION BETWEEN FERMENTATION OF DEXTROSE AND LACTOSE BROTHS. 



We have noted before that the power of carbohydrate fermenta- 

 tion is specially characteristic of the parasitic cocci, and of those 

 which do not show the packet grouping. The high acidities are 

 also correlated with a positive reaction to the Gram stain and with 

 a faint surface growth on artificial media. 



TABLE 27. 

 CORRELATION BETWEEN FERMENTATION OP DEXTROSE BROTH AND NITRATE REDUCTION. 



Table 27, for the relation between nitrate reduction and acid 

 formation in dextrose broth, shows only that the class of strong
