FOODS— HUMAN NUTRITION. 



Dietary studies in public institutions {E. *S'. Dcpt. Agr., Office Expt. Stas. 

 Bui. 223, pp. OS). — This bulletin contains two papers, namely. Dietary Studies 

 in Public Institutions in Philadelphia. Pa., by Emma Smedley and R. D. Milner, 

 and Dietary Studies in Public Institutions in Baltimore, Md., by H. L. Knight, 

 H. A. Pratt, and C. F. Langworthy. 



In the first of these papers the results are reported of a dietary study in a 

 home for old ladies and of one in an orphan asylum, and of the data obtained 

 regarding the selection of food, methods of preparation, and other questions of 

 institution management. On an average, the food consumed per woman per 

 day by the inmates of the old ladies' home supplied 58 gm. protein and 1,882 

 calories of energy, the cost being IS cts. per woman per day. In the orphan 

 asylum the food supplied G7.G gm. protein and 1,SG7 calories per child per day.
