figures is essentially different, as already explained. From the re- 
sults last given, assuming the gain of energy to have been entirely 
in the form of fat, Kellner * computes that the conversion of starch 
into fat in cattle takes place according to the following scheme:

Oil.—Applying to Kellner’s three experiments upon the addition 
of oil to a basal ration the same method of computation which was 
used for the starch—that is, computing the apparent utilization— 
we have the results shown in the two following tables:
