LECTURE XXVIII. 



In the table on page 645 are given the results of a few observations 

 with regard to the amount of nourishment taken by different classes of 

 people. 



Atwater has published the following values for the different classes in 

 the United States. 1 



C. Voit and Max Rubner 3 compute the total food consumption per day 

 for adults to be per head: 



1 W. O. Atwater: Storr's Agricul. Experim. Station, Storr's Conn. Ann. Report, 9, 152 

 (1896) (1891-1896). 



2 The numbers in parenthesis represent the number of dietary studies upon which 

 these average values are based. In several cases experiments were made with a family 

 in the fall and spring of the year, thus making two dietary studies with one family. Thus 

 in the first case there were five farmers' families which were under observation. (Trans- 

 lator.)

 Leyden, Part 1, 154 (1857), and Konig: loc ciL
