Woekingman's Model PIomb. 425 



snmed is very slightly in excess of both the American and German 

 standards. The carbohydrates are considerably in excess of tlie Amer- 

 ican standard, while the fats fall below. This may be l)ecause the 

 experiment was conducted through the hot weather of July. Though 

 the fats fall somewhat below the American standard they are largely 

 in excess of the German. The calories, or lieat and mechanical energy 

 values of the food consumed, are up to tlie standard. 



The health of the fa,mily throughout the month was good. The 

 physician looked in upon tliem occasionally, from interest in the exper- 

 iment, but there was no need of his professional services. The man 

 and woman both declared themselves perfectly content with the quan- 

 tity and qnality of the food they had been given, the man adding 

 that he would be willing to live on sncli a diet indefinitely, provided he 

 might have a little more fresh fruit in the hot weather. 



The physician's examination at the end of the experiment showed 

 that the family were in as good health at the end as at the beginning 

 of the month. Unfortunately, the examination, including the re-weigh- 

 ing, could not take place at the same hour of the day as the original 

 weighing. The latter took place on July second at one p. m. imme- 

 diately after a hearty dinner. The former was unavoidably delayed 

 until six p. M. of July thirty-first, nearly six hours having elapsed since 

 a meal. The same clothing was worn on both occasions. The second 

 weighing gave the result : Man, 185^ pounds ; woman, 99^ pounds ; 

 boy of eight, 53f pounds ; girl of six, lof pounds ; boy of five, 40f 

 pounds. 



The man showed a considerable gain. If the woman had lost more 

 than the record shows it would not have been remarkable considering 

 the circumstances under which she worked during the month. All the 

 housework for a family of five persons, cooking, washing and ironing, 

 etc., was necessarily carried on in the presence of from 500 to 2,000 

 persons daily. This was a strain to which she was unaccustomed, and 

 it speaks well for the diet that she did not loose more. The children 

 held their own, though the experimenter was disappointed that there 

 was no perceptible gain, since they were broken during the month of 

 their bad habits of eating'. Though previously well fed, they had been 

 accustomed to eating between meals when they felt hungry, and had 

 been given injudicious quantities of cake and candy. It is likely 

 that another month of simple diet and regular hours would have 

 resulted in a visible gain. 



The average cost per day of the food was fifty-four cents, one cent 

 less than was estimated. In the bills of fare fractions of a cent are 

 given. This is perfectly fair as will be seen if one takes for example 

 the case of sugar. JSToiie was wasted, and if only two or three ounces 

 were used each day it is obviously proper to use the fraction of the 

 cost per pound. 



Under other conditions it would have been possible to do more scien- 

 tific work in such an experiment. At the same time it must be remem- 

 bered that the very conditions that hampered in one way were those 

 necessary for the success of the experiment in another, as the chief
