SALICYLIC ACID AND SALIC YLATES. 665 



No. 3. 



The sheet for No. 3 is offered without comment on account of the 

 illness and consequent interruption of the normal functions during a 

 part of the period of observation. 



In the case of No. 4 it is seen that the average daily calories in the 

 food number 2,769 in the fore period, 2,833 in the preservative period, 

 and 2,904 in the after period, showing a progressive increase in the 

 calories of the food. There is a corresponding decrease in the average 

 daily calories in the feces, falling from 94 in the fore period to 91 in 

 the preservative period and 85 in the after period. In the urine the 

 quantity of calories in the preservative period is slightly less than 

 during the fore period and the after period, being practically identical 

 for these two periods. In this connection, however, the increase in 

 the calories in the food in both the preservative and after periods 

 must be remembered. The largest balance is found in the after period 

 and the smallest in the fore period. The decrease in the calories in 

 the feces and their almost constant value in the urine do not corre- 

 spond to the increase of the calories in the food. The data therefore 

 show an increased consumption of the heat values of the foods during 

 the administration of the preservative and in the after period. 



No. 5. 



The quantity of calories in the food of No. 5 is almost the same for 

 all three periods, being identical for the fore and preservative periods 

 and only 8 calories less for the after period. The calories in the feces 

 are greatest in the fore period, namely, 116, and decrease throughout, 

 being least in the after period. There is but little change in the cal- 

 ories in the urine, a slightly larger number appearing in the preserva- 

 tive period and the after period than in the fore period. The balances 

 are almost the same for all the periods, increasing very slightly in the 

 preservative and after periods. The data show again a tendency to 

 diminish the calories in the feces by the administration of the pre- 

 servative, although a corresponding decrease is not observed in the 

 urine. This indicates an increased consumption of the heat values of 

 the food during the preservative period, and this tendency is continued 

 in the after period. 



No. 6. 



The calories in the food for No. "6 are somewhat greater in the pre- 

 servative period and in the after period than in the fore period. The 

 quantity appearing in the feces is almost the same for the fore and
