The cost of the diet per man per day varied in these studies from 

 16.5 cents in the lowest to 41. S cents in the highest, but in most cases 

 the range above or l)elow the average, 26.8 cents, was considerabl}" 

 within these limits. In none of the Chicago studies was the expense 

 as small as in two of the Philadelphia studies, but in three of the for- 

 mer it was larger than the largest among the latter. 



In only three of the Chicago studies was the quantity of protein 

 less than 100 grams per man per day. In two of these it was 94 grams 

 and in one 79 grams. Probably in the latter case the figures should 

 really be larger. One of the two men in the family was ill during 

 the time of the study and doubtless ate less than he would when well, 

 but in the calculations of the results of the study he has been credited 

 with tliree full meals each day. 



Concerning the dietary study No. 51a, with 189 grams of protein 

 per man per day, and study No. 59a, with 209 grams, it has alread}' 

 been mentioned that the results are considered doubtful. Of the 

 remaining studies the results of a few showed fairly large quantities 

 of protein and energy per man per day, but the diet in the majority 

 supplied not very far from the average of all the studies, namely, 127 

 grams of protein per man per day. This is practically the same as 

 that of the commonh' accepted American standard for a man at mod- 

 erate muscular work, i. e., 125 grams per day. The energy of the 

 average, 3,664 calories per man per day, is but 164 calories above 

 that triven bv the standard iust mentioned. 



As in the case of the Philadelphia studies, the data concerning the 

 occupations of the families were so few that but little can be said 

 regarding the adequac}^ of the diet; but it may be inferred that it was 

 sufficient. The families in these studies were more intelligent and were 

 in better circumstances than were those in Philadelphia. They had
