DIETARIES AND RATIONS. 29 



been made to adjust the composition of the rations to the work 

 required, for the amounts of the pulse, seaweed, and other 

 vegetables rich in nitrogen, are the same for all the classes, the 

 quantities of rice or rice and barley given being augmented. As 

 the body-weights of the Japanese prisoners do not differ much from 

 those in Indian jails, we may usefully quote here the rations of 

 such a prison as that of Tokio. 



The small quantities of albuminoids and of fat in these rations, 

 and the excessive amount of starch, are very noticeable. In dietary 

 c the nutrient-ratio of i : 8*6 should be contrasted with that of C 

 given on p. 20, namely, i : 4 '66. 



The following are additional standard dietaries, reduced in the 

 case of rations for adults, to a mean body-weight of 105 Ibs. 



Albuminoids. Fat. Starch, etc. Nutrient-ratio. 



I. Children of 6 to 15 years... 27 ... 1-3 ... 87 ... i : 4*33 



II. Ordinary labour 3*12 ... 2-34 ... 10-37 ... i : 5-04 



III. ... 3 >][ 5 ; I>2 r 4' 02 x : 5 33 



The amount of mineral matter, including common salt, required 

 per day, is just under i ounce. 



It should be observed that the amount of oil or fat in the 

 dietary III. just given, is rather lower than is desirable. It 

 could not, however, be increased unless a considerable diminution 

 of the starch, already too high, were also effected ; of course, the 

 amount of albuminoids would then have to be raised as the 

 proportion in which they exist in this dietary is low. 



Many other standard dietaries have been proposed from time 

 to time, in addition to those already given in previous paragraphs. 

 On comparing them with all or nearly all the public dietaries 

 in actual and extensive use, the latter show a deficiency of 

 albuminoids and fat, and an excess of carbohydrates. The great 

 cost of butchers' meat and the difficulty of obtaining regular
