510 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



0.95 per cent, respectively, of the weight of the body. The average 

 weight of No. 5 for the fore period is 59.76, for the preservative 

 period 59.71, and for the after period 59.33 kilograms. There is 

 scarcely any change of weight between the fore period and the pre- 

 servative period, but a decided loss during the after period, in spite 

 of a slightly increased quantity of food. 



The average quantity of moist food consumed daily during the fore 

 period by No. 6 is 2,289 grams, corresponding to 537 grams of dry 

 material, equivalent to 3.94 and 0.92 per cent, respectively, of the 

 weight of the body. During the preservative period the mean daily 

 quantity of moist food consumed is 2,372 grams, corresponding to 556 

 grams of dry material, equivalent to 4.17 and 0.98 per cent, respec- 

 tive h r , of the weight of the body. During the after period the quan- 

 tity of moist food consumed daily is 2,275 grams, corresponding to 

 561 grams of dry material, equivalent to 4.07 and 1 per cent, respec- 

 tively of the weight of the body. The mean daily weight of No. 6 

 during the fore period is 58.06, for the preservative period 56.94, 

 and for the after period 55.87 kilograms. These data show a very 

 decided loss of weight during the preservative period, although the 

 quantity of dry food consumed was somewhat greater than in the 

 fore period. This loss of weight was continued through the after 

 period and the total decrease was considerable, namely 2.19 kilograms. 

 The amount of dry food consumed increased throughout the series. 



The quantity of moist food consumed daily by No. 7 during the fore 

 period is 2,203 grams, corresponding to 481 grams of dry material, 

 equivalent to 3.24 and 0.71 per cent, respectively, of the weight of the 

 body. During the preservative period the daily quantity of moist 

 food consumed is 2,333 grams, corresponding to 482 grams of dry 

 material, equivalent to 3.47 and 0.72 per cent, respectively, of the 

 weight of the body. During the after period the quantity of moist 

 food consumed daily by No. 7 is 2,261 grams, corresponding to 488 

 grams of dry material, equivalent to 3.41 and 0.74 per cent, respect- 

 ively, of the weight of the body. The average weight of No. 7 during 

 the fore period is 67.91, during the preservative period 67.28, and 

 during the after period 66.33 kilograms. There is thus observed a 

 considerable loss of weight during the preservative period as com- 

 pared with the fore period (630 grams), and an increased loss of weight 

 during the after period (950 grams). The respective quantities of food 

 consumed are almost the same for the three periods. There is, how- 

 ever, an increase of 7 grams of dry food daily in the after period over 

 the fore period, and of 6 grams daily in the after period over the pre- 

 servative period. This continued loss of weight, attended as it is with 

 a slight increase of the weight of food consumed, can only be attri- 

 buted to the persistent effects of the preservative upon the metabolic 

 processes.
