SALICYLIC ACID AND SALICYLATES. 631 



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. 



On account of illness this subject did not complete the experiment, 

 but left the table during the after period. For reasons given else- 

 where (p. 587) this subject is omitted from the summaries. The results 

 are given here as a matter of record. 



The amount of sulphur consumed in the food by No. 10 is 1.086 and 

 1.186 grams, daily, for the fore and preservative periods, respectively. 

 Of this amount 0.125 and 0.118 gram, respectively, appear in the feces, 

 and 0.852 and 0.840 gram, respectively, in the urine. Expressed in 

 percentages, of the total sulphur contained in the food there appear 

 for the fore period and preservative period in the feces 11.53 and 

 9.93 per cent, and in the urine 78.41 and 70.77 per cent, respectively. 



The balance is positive in both periods, its magnitude being increased 

 in the preservative period. 



No. 11. 



The quantities of sulphur in the food of No. 11 for the three periods 

 are 1.217 grams, 1.168 grams, and 1.153 grams, respectively. Of this 

 there appear in the feces 0. 1 52 gram, 0. 154 gram, and 0. 133 gram, respec- 

 tively, for the three periods, -and in the urine 1.000 gram, 0.985 gram, 

 and 0.963 gram, respectively, for the three periods. Expressed in 

 percentages, of the total amount of sulphur contained in the food 

 there appear for the three periods in the feces 12.48 per cent, 13.21 

 per cent, and 11.56 per cent, respectively, and in the urine 82.13 per 

 cent, 84.34 per cent, and 83.54 per cent, respectively. The balance 

 is slightly positive in all cases, but its magnitude is considerably 

 diminished during the preservative period. The preservative in this 

 case appears to have slightly increased the percentage both of non- 

 metabolized and metabolized sulphur excreted. 



The quantity of sulphur which is contained in the food of No. 12 

 for the three periods is 1.114, 1.146, and 1.098 grams, respectively. 

 Of this amount there appear in the feces 0.139, 0.115, and 0.122 gram, 

 respectively, for the three.periods, and in the urine 1.008, 0.972, and 

 1.016 grams, respectively. Expressed in percentages of the total 

 amount of sulphur in the food there appear in the feces 12.51, 10.03, 

 and 11.15 per cent respectively, for the three periods, and in the urine 

 90.53, 84.76, and 92.54 per cent, respectively, for the three periods. 

 The balance is slightly negative in the fore period and after period
