790 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



decrease in weight is associated with a very slight increase in the 

 quantity of food consumed, amounting to 16 grams a day in the pre- 

 servative period and 44 grams per day in the after period, as com- 

 pared with the fore period. The weight of the dry food consumed 

 in the fore period is 1.02 per cent of the weight of the body, in the 

 preservative period 1.05 per cent, and in the after period 1.10 per 

 cent. 



The average weight of No. 7 during the fore period is 70.46 kilo- 

 grams, and the average weight of dry food consumed is 560 grams, 

 amounting to 0.79 per cent of the weight of the body. The data for 

 the remainder of the observation in the case of No. 7 are incomplete 

 for the reasons given in the medical history. In this case we undoubt- 

 edly find an illustration of the results of a vivid imagination in con- 

 nection with the symptoms produced by the preservative period, which 

 finally led the subject into a state of susceptibility which rendered it 

 inadvisable to continue the experimental work with him. 



The average weight of No. 8 during the fore period is 61.68 kilo- 

 grams, during the preservative period 61.73, and during the after 

 period 61.83. The average quantity of dry food consumed by No. 8 

 during the fore period is 647 grams, during the preservative period 

 641 grams, and during the after period 661 grams. The percentage 

 of dry food consumed compared with body weight is 1.05 in the fore 

 period, 1.04 in the preservative period, and 1.07 in the after period. 



These data show a very slight increase of weight during the pre- 

 servative period, although the quantity of food consumed is 6 grams 

 less per day. During the after period, when the quantity of food 

 consumed was 14 grams per day larger than in the fore period, the 

 average increase in weight amounted to 100 grams over the preserv- 

 ative period. 



The average weight of No. 9 during the fore period is 62.23 kilo- 

 grams, during the preservative period 62.50, and during the after 

 period 62.37. The average quantity of dry food consumed daily is 

 550 grams in the fore period, 548 grams in the preservative period, 

 and 549 grams in the after period. These data show a very slight 

 increase in the weight of the body during the preservative period and 

 an almost constant quantity of dry food consumed. The percentage 

 of dry food consumed, based on the weight of the body, is 0.88 for each 

 of the three periods. 



The average weight of No. 10 during the fore period is 57.09 kilo- 

 grams, during the preservative period 57.17, and during the after 

 period 57.42. The average quantity of dry food consumed daily by 

 No. 10 is 593 grams in the fore period, 600 grams in the preservative 

 period, and 589 grams in the after period. The percentage of body 

 weight consumed as dry food is 1.04 in the fore period, 1.05 in the 

 preservative period, and 1.03 in the after period. These data show a
