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.
