In Eui^ope the minimum food value of the diet necessary for 

 the maintenance of physical health and efficiency has been laid 

 down by numerous observers, and in recent years a very close 

 agreement has been reached among investigators in Europe and 

 America. The best figures are, undoubtedly, those of Atwater in 

 Aipertca ' which follow. In accordance with modern ideas of the 

 replaceability of various food constituents, only the albuminoids 

 (protein) and Fuel- value are indicated, it being considered of

The figure obtained for the diet under discussion is, it will 

 be seen, equivalent in albuminoids to that of Atwater's standard 

 of a man with little physical exercise only. In the present
