686 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



No. 9. 



The daily quantity of solids in the food of No. 9 is 634 grams in the 

 fore period, 624 grams in the preservative period, and 623 grams in 

 after period. Of this quantity there are found in the feces 16 grams 

 in the fore period, 23 grams in the preservative period, and 18 grams 

 in the after period. In the urine there are found 66 grams in the fore 

 period, 71 grams in the preservative period, and 72 grams in the after 

 period. 



The largest percentage of solids in the feces occurs in the preserva- 

 tive period, namely, 3.75 per cent, and the smallest in the fore period, 

 namely, 2.44 per cent. The largest percentage of solids in the urine 

 occurs in the after period 11.55 per cent and the smallest in the fore 

 period 10.48 per cent. The balance was positive in all cases, the mag- 

 nitude being greatest in the fore period and least in the preservative 

 period. 



For reasons given elsewhere (p. 587), the results obtained with this 

 subject are not included in the summaries. They are stated here, 

 however, as a matter of record. 



No. 10. 



Owing to illness this subject was not connected with the experiment 

 during the second half of the after period. The daily quantity of 

 solids in the food of No. 10 in the fore period was 660 grams and in 

 the preservative period 676 grams. Of this quantity there are found 

 daily in the feces 21 and 18 grams, respectively, and in the urine 54 

 and 56 grams, respectively. 



Expressed in the form of percentage, we have in the feces the elimi- 

 nation of 3.20 and 2.68 per cent, respectively, and in the urine 8.11 

 and 8.27 per cent, respectively. 



The balance is somewhat increased in the preservative period. Not- 

 withstanding the slightly increased consumption of solids in the pre- 

 servative period, the solids eliminated in the feces are slightly less 

 during the preservative period than in the fore period. The solids 

 eliminated in the urine are approximately the same. 



For reasons given elsewhere (p. 587), this subject is omitted from the 

 summaries. The results are given here, however, as a matter of record. 



No. 11. 



The total quantity of solids in the food of No. 11 in the fore period 

 amounts to 621 grams daily, in the preservative period 622 grams 

 daily, and in the after period 615 grams daily. It is thus seen that 

 there is very little variation in the quantity of solids during the whole 

 course of the observation. Of this amount 25 grams daily appear in
