ties of nutrients and energy procured were notieealily larger for the 

 former. 



The onl}' native American famil}" included in these studies was that 

 in study No. 25a. The}" spent 25 cents per man per day, foi- which 

 they secured 83 grams of protein and 2,861 calories of energy — a diet 

 exactly tlie same in protein and ])ut very little higher in energy than 

 that in stud}^ No. 14a (a German- Jewish familv). which cost 6 cents per 

 dav less. 



Most of the above comparisons of di tie rent diets as regards economy 

 have been made between families of the same nationality. Similar facts 

 are observed in comparing the results with families of different nation- 

 alities. Thus in dietary study No. 24a with the German-American 

 family the cost of the diet was 20.2 cents per man per day, for which 

 150 grams of protein and 5,063 calories of energy were secured, while 

 in dietar}" study No. 2Sa, with an Irish family, the cost per man per day 

 was exactly the same, but only 90 grams of protein and 3,190 calories 

 of energy were secured. The family of Roumanian Jews in dietary 

 study No. 10a spent 21 cents per man per day, a trifle more than the 

 two families just mentioned, and secured 165 grams of protein and 

 3,5(»2 calories of energy; that is, little more pi'otein but nuu h less 

 energy than in the family in study No. 21a. Again, the colored family 

 in dietary study No. l<>a spent 17.2 cents per man per day and secured 

 but SO grams of protein and 1,967 calories of energy, while the Ger- 

 man family in study No. 21a spent 17.3 cents per man per day and 

 secured 118 grams of protein and 3,351 calories of energy. The two 

 most expensive dietaries in the whole number were that of the Italian 

 family in the stud}^ No. 13a and that of the Irish family in study No. 

 26a. The former spent 35.4 cents per man per day and secured 127 

 grams of protein and 2,462 calories of energ}^ while the latter spent 

 35.8 cents per man per day and secured 160 grams of protein and 4,084 

 calories of energy. 



It is interesting to observe that the family in study No. 13a consisted 

 of two women; so also did those in Nos. 25a and 11a. In all three the 

 cost calculated to the basis per man per day was high, but the economy 

 of the diets purchased varied widel3^ 



So few data regarding the occupations of the different families are 

 available that but little can be said concerning the fitness of the diets. 

 Most of the families were without regular incomes, so it may be 

 inferred that they were not engaged in steady work. The average of 

 the 22 studies summarized above agrees practically with the common 

 standard for a man at light to moderate muscular work; the number 

 of studies in which the diet was fairly near the average, however, was 

 small, the larger part of them being either considerabl}" higher or 

 lower than this. The family in study No. 27a was that of a store- 

 keeper. The diet in this study, furnishing 153 grams of protein and
