To be sure the cows gave less milk during the third period, after 

 the larger ration was restored than in the previous period on a 

 smaller hay ration, but it was easy for the experimenter to sc •^hat 

 the animals were using their food to recover from the depr ing 

 effect of an insufficient food supply. It is also noteworthy that 

 during the last half of the third period the cows had not only 

 recovered their loss of weight but had begun to gain in milk yield. 

 The writer cannot resist the temptation to call the attention of 

 those who believe that the ration largely controls the quality of the 

 milk to the fact that although the cows lost flesh and diminished 

 greatly in their product, the quality of the milk seems not to have 

 been influenced. 



Attention is also directed to the great variations that occurred 

 from day to day in the quality of the milk, although no changes 

 occurred in the food.
