Having given the average results of the several trials and the 
analytical data obtained, we may now briefly discuss the points 
under consideration. 
INFLUENCE OF FOOD ON THE MILK. 
With Jem and Meg under hay feed, the lowest milk yield per 
day was had, but the addition of corn meal to the ration increased 
markedly the flow of milk. In the two periods following the corn 
meal, with linseed meal and with wheat bran, there was a oradual 
diminution in the milk flow. Similar results followed in the trial 
with Ceres and Juno, but the figures for Juno should not enter 
into the comparison, although given, since she refused to eat her 
ration of linseed meal or of wheat bran, except in small quantities, 
which probably did not average more than one pound per day for 
the period. | 
The analysis of the milk shows somewhat the influence of the 
food, but it is only in the absolute amounts of solids and fat per 
day that we can trace fully the influence. Although the milk yield 
fell off considerably in periods three and four over that of period 
two, yet the absolute amount of fat per day was greatest in period 
three under linseed meal feed. Particularly is this the case with 
Ceres. We can not, however, attribute the increased fat to the 
peculiar properties of any particular feed, since the ration in
