SALICYLIC ACID AND SALIC YLATES. 667 



No. 10. 



Owing to illness, No. 10 was not under observation during the last 

 half of the after period. 



The calories in the food were greater in the preservative period than 

 in the fore period. Notwithstanding this, however, the calories appear- 

 ing in the feces were somewhat greater in the fore period than in the 

 preservative period. The calories appearing in the urine were prac- 

 tically the same for the two periods. 



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. 



In the case of No. 11 the calories in the food are slightly diminished 

 in the preservative period and still further decreased in the after 

 period. There is also a diminution in the calories in the feces during 

 the same periods, which, as shown by the percentage data, is relatively 

 a larger decrease than the diminution of the calories in the food. It 

 is fair, therefore, to attribute a part of this decrease to the influence 

 of the preservative. There is a slightly smaller number of calories in 

 the urine during the preservative period, corresponding very closely 

 to the diminution of the number in the food, and the same is true of 

 the after period, as is shown by the percentage of elimination. Thus 

 in this case the diminution is somewhat greater than the smaller quan- 

 tity in the food would account for, and the data show a tendency on 

 the part of the preservative to diminish the calories in the feces and 

 also in the urine, and this tendency is more marked in the urine in 

 the after period. 



No. 12. 



In the case of No. 12 there is a rapid diminution in the calories in 

 the food from the fore to the after period. There is a very marked 

 decrease in the calories in the feces in the preservative period, greater 

 than can be accounted for by the diminished calories in the food. In 

 the after period there is a larger quantity of calories in the feces than 

 in the preservative period, although the amount in the food is smaller. 

 The number of calories excreted in the urine during the three periods 

 remains almost the same. The data show a marked effect of the pre- 

 servative in diminishing the calories in the feces during the preserva- 

 tive period with practically* no effect upon the calories in the urine. 

 Inasmuch, however, as the calories in the food are diminished, there is 

 an increase in the percentage eliminated in the urine in the after period.
