the dry food consumed is almost 1 per cent of the weight of the body, 

 being 0.98 per cent in the fore period, 0.99 in the after period, and 

 0.95 in the preservative period. 



The average weight of No. 2 in the fore period is 70.18 kilograms, in 

 the preservative period 69.61, and in the after period 69.27. The 

 average weight of dry food consumed daily by No. 2 is 664 grams in 

 the fore period, during the preservative period 658 grams, and in the 

 after period 663 grams. The ratio of dry food consumed to the 

 weight of the body is practically constant for No. 2 during the entire 

 period of observation, being 0.95 per cent for the fore period, 0.95 for 

 the preservative period, and 0.96 for the after period. 



The average weight of No. 3 for the fore period is 63.81 kilograms, 

 for the preservative period 64.07, and for the after period 64.50. 

 There is thus seen to be a slight gradual increase in weight during the 

 entire observation. The average weight of dry food consumed daily 

 by No. 3 is very constant, amounting to 660 grams during the fore 

 period, 662 grams during the preservative period, and 683 grams 

 during the after period, representing 1.03, 1.03, and 1.06 per cent, 

 respectively, of the body weight. 



The average weight of No. 4 during the fore period is 62.97 kilo- 

 grams, during the preservative period 62.73, and during the after 

 period 61.88. In this case there is an opposite tendency shown to 

 that of No. 3, namely, a progressive decrease in weight during the 

 period of observation, and this has taken place in connection with a 

 small increase in the weight of dry food consumed daily, which, in 

 the fore period, is 608 grams, in the preservative period 621 grams, 

 and in the after period 631 grams, equivalent to 0.97, 0.99, and 1.02 

 per cent, respectively, of the weight of the body. 



The observations for No. 5 in the fore period are confined to the 

 second subperiod. The data, although they are given in full in so far 

 as obtained, are not of much value, because of the febrile disturbance 

 in the case of No. 5, described in the medical history. 



The data show the average weight for the fore period to be 52.72 

 kilograms, for the preservative period 52.49 kilograms, and for the 

 after period 51 kilograms. The average daily quantity of dry food 

 consumed in the fore period is 626 grams, in the preservative period 

 536 grams, and in the after period 502 grams, equivalent in the fore 

 period to 1.19 percent of the body weight, in the preservative period 

 to 1.02 per cent, and in the 1 after period to 0.98 per cent. 



The average weight of No. 6 during the fore period is 58.74 kilo- 

 grams, during the preservative period 58.66, and during the after 

 period 58.43, showing a slight tendency to a decrease in the weight 

 of the body. The average quantity of dry food consumed daily by 

 No. 6 is 598 grams during the fore period, 614 grams during the pre- 

 servative period, and 642 grams during the after period. Thus, the
