Sill's" experinientiil study of malnutrition in tlio school cliiM in 

 New York City deserves special mention, as it records experimental 

 data. An improvement in health and f^eneral condition, it is stated, 

 was ohserved when living conditions were made more hygienic and 

 the children were given a generous diet. 



The Starr ("enter Association '' in Philndclphiii has puhlished 

 reports describing the movement which has resulted in supj)lying 

 penny lunches to cliildren in a number of schools in thickly congested 

 districts. 



COST OF LIVING AND OTHER SOCIOLOGICAL DATA. 



Doubtless owing to the increased cost of food and other necessities, 

 not only in the United States but in most coimtries, more attention 

 than usual has been paid during the last year and a half to the cost 

 of living and reports on this subject have been quite numerous. 

 Among other papers may be mentioned a study of the cost of living 

 in New Jersey. *" 



Data on these topics are also included in a report on retail prices 

 of food, 1890 to 1907, published by the United States Bureau of 

 Labor.'^ As the subject is one which is so extended that it requires, 

 independent treatment, no attempt wdll be made here to summarize 

 the numerous similar articles w'hich have appeared in bulletins, 

 periodicals, and other publications. 



A number of sociological studies of workingmen's families which 



include food and nutrition topics and other data have appeared, 



including Chapin's '^ study of living conditions in wage-earners' 



families in New York City. Similar work with farmers' families, 



carried on by the Minnesota Experiment Station in cooperation with 



the Department of Agriculture, has been referred to elsewhere. (See 



p. 386.) 



DIGESTIBILITY OF FOOD. 



During the period included in this summary numerous studies 

 have been made of the thoroughness of digestion of foods under a 

 variety of conditions. 



Many of the experiments made to determine the digestibility of 

 food materials were carried out as special investigations, while some 

 were made in connection wnth studies of other problems. Thus,
