13.6 lbs., but as the amount was much larger at first, it is averaged 
for each four days of the period. The Ist being 18.2 lbs.; 2d, 
13.8 lbs., and the last 8.8 lbs. 
Period III, Mar. 31 to Apr. 9 inclusive. Ration, hay and a mixed 
feed same as period II, except the oil meal. The hay eaten aver- 
aged for the period 12 1-2 lbs. per day. The average for the first

The hay eaten averaged 9 lbs. per day. The average for the first 
three days being 6.3, and for the last three days, 11.7 lbs. 
The analyses of the substances composing these rations are given 
below:

From this is derived the following table, in which is given the 
weight in pounds of each constituent of the ration, except ash, con- 
sumed per day. The water contained in the food is added to that 
drank. The water drank in period I is assumed as 80 Ibs. per day, 
this being the average for this cow in an experiment when the ration 
was similar.
