The result of this study may quite properly be compared with those 

 of studies with attendants reported in this publication; that is, Nos. 

 365, 369, and 370. As regards food eaten the present study, averaging 

 140 grams of protein and 8,522 calories of energy per man per day, 

 shows the maximum as regards protein, being 9 grams higher than No. 

 370 and 40 grams higher than No. 369. In respect to amount of fat 

 eaten it was moderate, and was next to the lowest in respect to car- 

 bohydrates. The energy was lower than in the case of No. 370, which, 

 however, was extremely high, owing to the large amount of butter and 

 sugar eaten. 



A comparison of the food consumption of the persons here studied 

 with any dietary standard is almost impossible, because the group in- 

 cluded employees of both sexes and of varying degrees of muscular ac- 

 tivity. Moreover, some worked only from 8 a. m. to 5 p. m., while 

 others were on duty continuously from 8 a. m. to 9 p. m. It hardly 

 seems probable, however, that the demands of these persons for nutri- 

 ents and energy would be on the average any larger than are called for 

 by the previously mentioned dietary standard for a man at light to 

 moderate muscular work, namely, 112 grams of protein and 3,050 

 calories of energy per day. It is interesting to note that the results 

 of the study are considerably higher than the standard in respect to 

 both protein and energy. It is reasonably certain, therefore, that 

 these persons had amply sufficient or more than sufficient nourishment. 



The amount of food rejected in this study was sufficient to supply
