SALICYLIC ACID AND SALIC YLATES. 509 



during the preservative period and increased by a few grams during 

 the after period. 



The data for No. 3 are only fragmentary, as has already been 

 explained, and therefore are of little value for experimental purposes. 

 During the second subperiod of the fore period the quantity of moist 

 food consumed daily by No. 3 is 2,610 grams, equivalent to 530 grams 

 of dry material, or 5.18 and 1.05 per cent, respectively, of the weight 

 of the body. For five subperiods of the preservative period the weight 

 of moist food consumed daily is 2,568 grams, equivalent to 592 grams 

 of the dry material, corresponding to 5.04 and 1.16 per cent, respec- 

 tively, of the weight of the body. During the after period the quan- 

 tity of moist food daily consumed is 2,524 grams, equivalent to 621 

 grams of dry food, 4.89 and 1.20 per cent, respectively, of the body 

 weight. The average weight of. No. 3 during his fore period (five 

 days) is 50.42 kilograms, during the five subperiods of the preservative 

 period 50.93 kilograms, and during the after period 51.66 kilograms. 

 No. 3 therefore presents a progressive gain in weight and also an 

 increased quantity of dry food consumed. The explanation of this 

 condition in connection with the illness of the subject has already been 

 discussed under bod} 7 weights. 



The average weight of moist food consumed daily by No. 4 in the 

 fore period is 2,311 grams, equivalent to 535 grams of dry material, 

 these data corresponding to 3.80 and 0.88 per cent, respectively, of 

 the weight of the body. For the preservative period the average 

 quantity of moist food consumed daily is 2,378 grams, equivalent to 

 556 grams of dry material, corresponding to 3.92 and 0.92 per cent, 

 respectively, of the weight of the body. For the after period the 

 quantity of moist food consumed daily is 2,408 grams, corresponding 

 to 569 grams of dry material, equivalent to 3.98 and 0.94 per cent, 

 respectively, of the weight of the body. The mean weight of No. 4 

 for the fore period is 60.73, for the preservative period 60.67, and 

 for the after period 60.43 kilograms. The loss of weight is practically 

 negligible during the preservative period, and becomes a small though 

 noticeable quantity for the after period, notwithstanding the slightty 

 increased quantity of food. 



The quantity of moist food consumed daily by No. 5 during the 

 fore period is 2,357 grams, corresponding to 558 grams of dry mate- 

 rial. These data represent 3.94 and 0.93 per cent, respectively, of 

 the body weight. For the entire preservative period the average 

 daily quantity of moist food consumed is 2,346 grams, equivalent to 

 563 grams of dry material and corresponding to 3.93 and 0.94 per 

 cent, respectively, of the weight of the body. During the after 

 period the average daily quantity of food consumed is 2,382 grams, 

 corresponding to 564 grams of dry material, equivalent to 4.01 and
