a Butter equals fat plus one-sixth.

c Averages obtained by dividing the total weight of fat by the total weight of milk. 
One hundred and seventy pounds more milk were produced by the corn- 
meal ration than by the vegetable-ivory-meal ration. This excess is not 
pronounced; and while it is possible that the difference may be within 
the limit of experimental error when taken together with the fact that 
the corn-meal ration increased the live weight of the cows, it indicates 
at least that the com meal was somewhat superior to the vegetable- 
ivory meal as a source of nutrition.

The very concisely stated data of Table XVI of this experiment indi¬ 
cate that vegetable-ivory meal possesses a distinct feeding value and 
that, while somewhat inferior to com meal, the difference is not marked. 
As greater difficulty was met with in hydrolizing the carbohydrate of 
the vegetable ivory than the carbohydrate of other feeding materials, it
