508 INFLUENCE OF FOOD PKESEEVATIVES ON HEALTH. 



The data showing the average effect produced on the nine men 

 completing the series are plotted in the chart shown in fig. 2. It is 

 evident that this effect is toward a loss of weight during the pre- 

 servative period and an increased loss during the after period. In 

 other words, the larger relative loss produced during the after period 

 is due doubtless to the momentum, as it may be called, of the effects 

 produced during the preservative period. 



RATIO OF FOOD WEIGHT TO BODY WEIGHT. 



In Table IV are shown the results of the study made of the quantity 

 of food consumed as compared with the body weight. 



The average weight of No. 1 for the fore period is 53.38 kilograms, 

 for the preservative period 52.99 kilograms, and for the after period 

 52.37 kilograms. It is seen that there is a slight loss of weight during 

 the preservative period and a slightly greater loss during the after 

 period. The average weight of moist food administered during the 

 fore period is 2,427 grams and of dry food 467 grams. The daily 

 weight of moist food consumed is 4.55 per cent and of the dry food 

 0.87 per cent of the weight of the body. During the preservative 

 period the average daily quantity of moist food consumed is 2,421 and 

 of dry food 474 grams. The moist food consumed daily is 4.57 per 

 cent and the dry food 0.89 per cent of the weight of the body. Dur- 

 ing the after period the quantity of moist food consumed daily is 2,345 

 grams and of dry food 476 grams. The moist food consumed is 4.48 

 per cent and the dry food 0.91 per cent of the weight of the body. 

 It will be noticed that the quantity of dry food consumed during the 

 various periods is almost constant, being least in the fore period and 

 greatest in the after period. The loss of weight therefore can not be 

 ascribed to any diminution of the quantity- of food, the latter having 

 been slightly increased. 



In the case of No. 2 the average quantity oi; moist food consumed 

 during the fore period is 2,669 grams and of dry food 604 grams, 

 being 3.91 per cent and 0.88 per cent, respectively, of the weight of 

 the body. During the preservative period the quantity of moist food 

 consumed by No. 2 is 2,908 grams and of dry food 598 grams, being 

 4.30 and 0.88 per cent, respectively, of the weight of the body. Dur- 

 ing the after period the average quantity of moist food consumed by 

 No. 2 is 2,876 grams and of dry food 612 grams daily, being 4.30 and 

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



The average weight of No. 2 during the fore period is 68.32, during 

 the preservative period 67.66, and during the after period 66.91 kilo- 

 grams. There is thus seen a progressive loss of weight which con- 

 tinued through the after, period, although the quantity of food 

 remained practically the same, but was diminished by a few grams
