Dietary studies at Purdue University in 1895, W. E. Stone; 

 commeuts by W. O. Atwater aud C. ]). Woods ( T. *S'. JDejJt. Ayr., 

 Office of Experiment Stations Bui. 32, pp, 28). — Two dietary studies, one 

 of a teacher's family and one of a mechanic's family in Indiana, were 

 made in the customary maimer (E. S. If., 7, p. 148). A number of 

 Indiana foods were analyzed. The composition of other foods was com- 

 puted from standard tables. Tables are given showing the amount of 

 food ])urchased, wasted, and eaten, its cost, composition, and fuel value. 

 The results of these studies are briefly summed up in the following 

 table:

Xutrients. 



In the comments on these dietaries the results are compared with 

 results of similar studies made in other localities in the United States 

 and with the generally accepted dietary standards. 



" [These results] show very plainly that the more costly dietary is not necessarily 

 the more attractive or nutritious. It could not be said that the tinner's dietary
