INFLUENCE OF THE PLANE OF NUTRITION UPON MILK 69 



At the end of thirty days' underfeeding the saponificatioii 

 number was 222.1 ; after fourteen days on a normal ration it 

 was 225.7. During the same interval the iodin number de- 

 creased from 42.62 to 34.15; the Reichert-Meissl increased 

 from 21.43 to 24.2, and the melting point declined from 

 36.35 to 33.60. 



A summary of the results of twenty-three experiments is 

 given in Table VI. The plane of nutrition as indicated in 

 percentage is calculated on the basis of the requirements of 

 the animal in question calculated according to the Armsby 

 Feeding Standard. 



The data presented in Table VI have several striking feat- 

 ures. The most striking is the fact that without exception all
