tion of the lactic acid with the casein ol' the milk on the one hand and the 

 acetic with the. wort constituents on the other. In five daj-s the 5% 

 acetic acid had made available 75% ol" the PoOj; while the acetic germ in 

 fifteen days showed only 53.55%, the acidity of the culture being a little 

 less than 5%. Again, the 1% lactic acid gave 76.13% soluble PoOj in 

 five days while the lactic culture in milk of about the same acidity 

 gave only 23.31% in fifteen days. 



The details and results of these two Series are shown in Tables Nos. 

 13 and 14.
