sake of completeness. Those upon peanut oil have been omitted, 
since the varying effect upon digestibility and upon the methane 
fermentation makes the results as computed in this way appear 
of questionable significance. 
SummMary.—The average results upon the various materials 
experimented with are summarized on the opposite page. 
As appears from the figures of the table, the apparent metabo- 
lizable energy of the digestible organic matter of the different coarse 
fodders is quite uniform. At first sight it appears somewhat sur- 
prising that oat straw should show more favorable results than hay, 
but the reason is readily seen in the smaller loss which takes place 
in the urine; in wheat straw this loss is somewhat larger, while that
