SALICYLIC ACID AND SALIC YLATES. 685 



No. 7. 



The quantity of solids found in the food of No. 7 during the fore 

 period is 481 grams daily, during the preservative period 482 grains 

 daily, and during the after period 488 grams daily. Of this there 

 appear in the feces 14 grams daily in the fore period, 11 grams daily 

 in the preservative period, and IT grams daily in the after period. In 

 the urine are found 58 grams daily during the fore period, 54 grams 

 daily during the preservative period, and 49 grams daily during the 

 after period. Expressed in percentages the quantity of solids found 

 in the feces during the fore period is 2.95 per cent daily, in the pre- 

 servative period 2.21 per cent daily, and in the after period 3.44 per 

 cent daily, while in the urine are found during the fore period 12.02 

 per cent daily, in the preservative period 11.12 per cent daily, and in 

 the after period 10.12 per cent daily. The largest balance is in the 

 after period, namely, 422 grams daily, and the smallest in. the fore 

 period, namely, 409 grams daily. The principal effect of the pre- 

 servative in this case is to decrease the amount of solids in the feces 

 during the preservative period, a decrease which is more than regained 

 during the after period. The tendency also appears to be to decrease 

 the quantity of solids in the urine during the preservative period, and 

 this tendency is continued during the after period. 



No. 8. 



The quantity of solids in the food of No. 8 in the fore period is 531 

 grams daily, in the preservative period 575 grams daily, and in the 

 after period 587 grams daily. Of this quantity there are found in the 

 feces 17 grams in the fore period, 19 grams in the preservative period, 

 and 21 grams daily in the after period. In the urine there are found 

 54 grams daily in the fore period, 56 grams daily in the preservative 

 period, and 60 grams daily in the after period. The largest percentage 

 of solids in the feces occurs in the after period, namely, 3.56 per cent, 

 and the smallest in the fore period, namely, 3.14. The largest per 

 centage of solids in the urine occurs in the after period, namely, 10.25 

 and the smallest during the preservative period, namely, 9.71 per cent. 

 The largest balance is found in the after period, namely, 506 grams 

 daily, and the smallest in the fore period, namely, 461 grams daily. 

 There is an apparent tendency in this case for the preservative to 

 increase the quantity of solids in the feces, and this tendency is main- 

 tained through the after period. There is also manifested a tendency 

 on the part of the preservative to increase the actual amount of solids 

 in the urine in the preservative period, and this is continued in the 

 after period. There is, however, a decrease in the percentage amount 

 excreted in the urine in the preservative period.
