HEAT INCREMEXTS PER KILOGRAM OF DRY MATTER 



The results of the comparisons between periods made by the methods 

 just illustrated are contained in Table X. In those cases in which more 

 than two periods upon the same ration can be compared, the total heat 

 increments per kilogram of dry matter are recorded for each successive

 eaten. Table X shows the total heat increments computed by comparing 

 periods A with B; B with C; C with D; and finally A with D. The
