this average to the above figures, and assuming with Kellner that 
the protein does not take part in the methane fermentation, we 
have the following:

There is a wide discrepancy between these results and those 
computed on p. 465 from the experiments of Kern & Wattenberg 
upon sheep with conglutin and flesh-meal. Omitting the apparently 
exceptional result of Period II, we have the following as the per- 
centages of the (computed) metabolizable energy of the digested 
proteids which was utilized in those experiments:

While the gain in these cases includes a considerable growth 
of wool, it seems difficult to suppose that this alone can have made 
the conditions so much more favorable for the storing up of: the 
added protein as to account for the great difference between these 
results and Kellner’s, and it must apparently be left to further 
investigation to clear up the matter.
