dilations. There has been a rather steady small increase in total 

 gross food consumption, but this has been very closely proportional 

 to the increase in the population. 



In the seven-year period here discussed the greatest relative 

 advance in consumption was in respect of fat, and the least relative 

 advance in respect of protein. Carbohydrate content and calories 

 increased in the seven years in amount consumed to a degree inter- 

 mediate between fat and protein. The protein relative line falls 

 below the population relative line each year after 1913-14. This 

 means that since 1913-14 somewhat less protein has been consumed 

 in gross in proportion to the population. The relative line for fat 

 was below the population line till 1914-15, and thereafter followed 

 it closely. 



The relative figures from which Fig. i is plotted are given in 

 Table III. 



With such gratifying assurance of the smoothness of the con- 

 sumption results we may proceed to an analytical discussion of the 

 numerous highly interesting problems which center about human 

 food consumption, and for which data have hitherto been lacking.
