Prof. R. M. Washburn, formerly of the Vermont Experi- 

 ment Station, in a recent lecture before the Massachusetts 

 State Board of Agriculture, said: "In order to compare one 

 food with another it is necessary to compare foods which 

 have a similar nutritive ratio, and are either both of animal 

 or both of vegetable origin, for the digestibility of milk and 

 meat products is very materially greater than that of cereals 

 and garden vegetables." 



In the following tables, by the same authority, the foods 

 are grouped so that those of approximately like nutritive 

 ratios are compared against each other.
