684 INFLUENCE OF FOOD PKESEKVATIVES ON HEALTH. 



in the preservative and after periods, and this increase is only slightly 

 greater than the increase in the quantity of solids in the food consumed, 

 as shown by the percentages for the three periods, namely, 11. 72, 

 12.06, and 12.27. The largest percentage of solids in the feces is 

 found during the fore period and the smallest in the after period, and 

 this must be considered in connection with the increasing amount of 

 food, from which it might be expected that the solids in the feces would 

 increase proportionately, but this is not the case. 



No. 5. 



The total solids consumed daity in the food is 558 grams in the fore 

 period, 563 grains in the preservative period, and 564 grams in the 

 after period, showing a very small variation during the entire period 

 of observation. There appear in the feces during the fore period 25 

 grams of solids daily, in the preservative period 21 grams, and in the 

 after period 18 grams. IQ the urine there appear daily 57 grams of 

 solids in the fore period, 62 grams in the preservative period, and 62 

 grams in the after period. The largest percentage of solids in the 

 feces is in the fore period, namely, 4.53, and the smallest in the after 

 period, namely, 3.17. The largest percentage of solids in the urine is 

 found in the after period, namely, 11.03, and the smallest is found in the 

 fore period, namely, 10.23. The largest balance is in the after period, 

 namely, 484 grams, and the smallest in the fore period, namely, 476 

 grams. The apparent tendency of the preservative in this case is to 

 diminish the percentage of solids in the feces, and this tendency is 

 continued through the after period. On the other hand, there is a 

 slight tendency to increase the quantity of solids in the urine. 



No. 6. 



In the case of No. 6 the average daily quantity of solids in the food 

 is 537 grams in the fore period, 556 grams in the preservative period, 

 and 561 grams in the after period. Of this quantity there appear in 

 the feces during the fore period 26 grams daily of solids, during the 

 preservative period 25 grams daily, and during the after period 24 

 grams daily. There also appear in the urine 49 grams daily in the 

 fore period, 57 grams daily in the preservative period, and 56 grams 

 daily in the after period. Expressed in percentages, 4.84 per cent of 

 the solids appear in the feces in the fore period, 4.53 per cent in the 

 preservative period, and 4.28 in the after period. In the urine there 

 are found 9.20 per cent of solids in the fore period, 10.33 per cent 'in 

 the preservative period, and 9.98 per cent in the after period. There 

 is an apparent tendency in this case to slightly decrease the quantity 

 of solids in the feces, and this is continued through the after period, 

 and to slightly increase the quantity of solids in the urine during the 

 preservative period, and this is only slightly diminished in the after 

 period.
