THE UTILIZATION OF ENERGY. 
485 
Computed by Kellner’s method, the percentage of the metabo- 
lizable energy of the hay which was recovered as gain of tissue was 
as follows, as compared with the results obtained by the writer’s 
method:

Computing the results upon the gross energy of the digested 
matter of the hay, Kellner obtains the following: 
DISTRIBUTION OF ENERGY OF DIGESTED MATTER.

In Urine. In Methane. Assimilation, In Gain.

As in some previous cases, the numerical results of the two 
methods of computation do not vary greatly, but their essentially 
different significance should not be forgotten.
