Percentage Composition of Mill: 



Haiiiiniiii(l and Ha\vk(ii), ami otluTs, liavc shown that an inverse 

 relationship exists between the percentage of fat and the daily volume. 

 This was well brou<;ht out, but it may be seen from ¥\'^. 1 that the 

 percentage of protein also varied inversely as the volume with a regu- 

 larity at least equal to that of the fat, though the extent of the variation 

 was less marked. The percentage of lactose maintained a very constant 

 level, varying between M!) per cent, and A-'M) ))er cent. Tiic percentage 

 of ash, which varied from 0-94 per cent, to 1-(I8 per cent., may l)e seen 

 from the analytical data to have shown a tendency to rise with the fall 

 in volume towards tlie end of the e.xperuiient .

Experiment II. (Analytical Data, Table II.) 



The fluctuations in volume from day to day having been compara- 

 tively slight in the preceding experiment, advantage was taken in this 

 case of the decrease in yield brought about by an absence of food, and 

 the increase which follows the resumption of feeding. 



A goat was fed for eight days on an unrestricted diet of hay and 

 oatmeal, and on the 9th and 10th days no food was taken. PVom the 

 11 til dav onward the feeding was resumed.
