of the results given on pp. 304 and 306 for the digested crude fiber 
and nitrogen-free extract of coarse fodders, viz., 4.226 Cals. per 
gram. 
As a whole, the figures given on p. 329 show a tendency 
toward an increased production of methane with an increase in 
the proportion of crude fiber, but considerable variations are 
found in individual cases. 
It is evident, therefore, from these 
results, as well as from those already cited in connection with the 
experiments upon starch and upon molasses, that a variety of 
factors influence the extent of this fermentation. _
