Subtracting the results on the basal ration of Period A from those 
of the other periods, as in previous cases, we have the following:

Strictly speaking, only the first of the above percentages repre- 
sents the net availability for maintenance, since the other two 
include some gain. 
From the difference observed between the 
metabolism of the animal standing and lying, however, it was 
computed approximately what the gains would have been had the 
same position been maintained for the whole twenty-four hours, 
with the following results:
