Of the 4 equivs. carbonic acid, 2 equivs. are retained by 
the lime. 
The following proportions of hydrogen and carbonic acid 
were obtained at different periods of the fermentation 
(accompanied by evolution of hydrogen :) — 
150 H : 169 CO 2 = 4 : 4| 
140 H : 140 CO 2 = 4:4 
108 H : 186 CO 2 = 4:7 
120 H : 220 CO 2 = 4 : 7§ 
111 H : 221 CO 2 = 4:8 
From these relations it may be admitted that the butyric 
acid is produced both from the malic and the succinic acids, 
which would explain the decrease in the amount of the 
latter. 
The following analyses of the products of this process of 
fermentation were made by Mr. Halerow.
