A DROP OF MILK 



The thousands of different sized round bodies Hke floating bubbles shown in the photograph 

 are the butter fat globules which in churning are packed together and make butter, ihe 

 very small dark bodies are not fat. It is these butter fat globules which contam orie of the 

 essential vitamines (fat soluble A) necessary for the growth of the human body and it is this 

 fat of the cow which the European world is starving for. The Chinese and Japanese have 

 not become dependent upon it and if their cattle were all destroyed they would not suffer as 

 Europeans have. They get their fat soluble A direct from large quantities of fresh vegetables. 

 If the milk were richer, the fat globules would be larger and more closely crowded together. 

 It is both the amount of milk and the quantity of these globules which are taken into consider- 

 ation in grading cows. Photograph enlarged 350 diameters by John Howard Paine, {t ig. 6).
