SUMMARY 
The latest evidence in relation to the determination of the net 
energy of feeds, in accord with Armsby’s conception, having led (1) 
to a new and greatly improved method of correcting the heat produc¬ 
tion of the experimental animal to a standard day, in relation to the 
position of the subject as to standing and lying, and (2) to an impor¬ 
tant change in the method of computation of the net-energy value, 
it has become necessary to recompute and to correct the net-energy 
values of feeds, for the maintenance and body increase of steers, 
which have been published from the Institute of Animal Nutrition 
of the Pennsylvania State College (1 , 2 y 3> 4> 6> 8, 9 ). The corrected 
net-energy values are as assembled in Table VI.
