figure, and capacity to rear their young, as compared with Europeans 

 and Americans, except that we use much less of the leafy foods and 

 much more dairy products. 



Q. Your belief then is that the dairy products contain this vital 

 substance to promote growth to a larger extent than the green leaves ? 



A. Our conclusions are that the use of milk as a food to correct 

 the short comings of all other things that are commonly used as food is 

 a matter of the greatest importance to our welfare and that is a factor 

 of great importance in , determining the standard of public health. The 

 cow consumes relatively enormous amounts of leafy foods in the form 

 of hays and silage and the rest of her diet is a grain diet of by-products 

 in the milling industry; the peculiar qualities of her milk are due to the 

 fact that she herself absorbs so much of the products derived from the 

 leafy portion of her food. 



Q. You feel that the cow's digestive organs are so arranged that 

 she can consume a sufficient quantity of these green leaves to keep her- 

 self in a normally healthy condition? 



A. There is no question about that. 



Q. What do you call these substances? 



A. I have tabulated in my note-books about twenty-five different 

 names that have been given to these three different substances. The first 

 name that appeared and the one which is still most popular, is the term 

 'Vitamine/ 



Q. How do you spell that ? 



A. V-i-t-a-m-i-n-e-s. They have been termed 'Acessory Food Sub- 

 stances/ I gave two of them a name, designation letters of the alphabet, 

 differentiated on the basis of their solubility; one, Tat Soluble A/ and 

 two, 'Water Soluble B.' Now, at that time that was all there were. Later 

 on it became necessary to modify that to designate one that protects 

 against scurvy that is recently denominated as 'Water Soluble C/ 



Q. Which one of these promotes growth in the individual ? 



A. He must have all three of them present in order for growth and 

 health to be maintained. 



Q. Now, is it your idea from these experiments that human beings 

 will do better if they consume the correct amount of butter fat and of 

 milk than they will if they try to maintain their lives on green leaves? 



A. I have been, forced to the conclusion that milk is a better food 

 for the correction of the faults in cereal and meat diet than are the leaves, 

 largely because of the concentrated character of the food. 



Q. You think that the civilized nations of the world then owe their 

 development to the use of dairy products?
