 demonstrated that normal growth of certain higher animals, and 

 probably also of man, requires a diet which must be sufficient 

 in certain accessory foods or vitamines.

tamines in the various natural foods. It is important to know 

 roughly whether a certain food like milk or barley is relatively 

 rich or poor in vitamines. Unfortunately we do not possess at 

 the present time a quantitative method for estimating the vi- 

 tamine content of a given food. The preceding table (Table 1) 

 illustrates the relative vitamine content of foods, beginning with 

 those richest in vitamines. I do not pretend that this table is 

 a very accurate compilation, but in our present state of knowl- 

 edge it will probably be found of some use in deciding questions 

 as to what constitutes a satisfactory diet from this point of view. 

 It is fortunate that most people, on account of their dietary 

 habits, live on a mixed diet containing enough of these accessory
