SALICYLIC ACID AND SALICYLATES. 647 



No. 3. 



The data for No. 3 are exhibited without comment by reason of the 

 conditions heretofore stated in connection with this member of the 

 table. 



No. 4. 



The average daily quantity of fat in the food of No. 4 in the fore 

 period is 96.51 grams, in the preservative period 92.77 grams, and in 

 the after period 91.42 grams. The relative amounts appearing in the 

 feces for the three periods daily are as follows: 



For the fore period 2.96 grams, for the preservative period 2.81 

 grams, and for the after period 2.58 grams. Inasmuch as there is a 

 slightly diminished quantity of fat in the food in the after period, as 

 in the previous case, a more comprehensive idea of the amount of fat 

 absorbed from the alimentary canal is found by an inspection of the 

 percentage column. This shows that 3.06 per cent of the fat was 

 excreted in the fore period in the feces, 3.03 per cent in the preserva- 

 tive period, and 2.82 per cent in the after period. These data show 

 practically no influence of the preservative as affecting the absorption 

 of the fat from the alimentary canal, but a considerable increase in 

 this absorption is noticed during the after period. 



No. 5. 



The average daily quantity of fat consumed by No. 5 in the fore 

 period is 96.82 grams, in the preservative period 94.03 grams, and 

 in the after period 91.37 grams. Here again we find a slightly dimin- 

 ishing quantity of fat throughout the three periods. The amounts 

 appearing in the feces during these three periods are, respectively, 

 3 grams, 2.80 grams, and 2.93 grams. Expressed in percentages, it is 

 seen that of the total fat in the food 3.10 per cent is excreted daily in 

 the feces of the fore period, 2.98 per cent in the preservative period, 

 and 3.21 per cent in the after period. 



These data again show the influence of the preservative in increas- 

 ing the absorption of the fatty substances from the alimentary canal. 



No. 6. 



The average daily quantity of fat in the food of No. 6 in the fore 

 period is 96.91 grams, in the preservative period 94.49 grams, and in 

 the after period 92.63 grams. The quantity appearing in tKe feces for 

 the fore period is 3.24 grams, for the preservative period 3.92 grams, 

 and for the after period 3.39 grams, which, expressed in percentages, 

 represents an excretion of fat in the feces in the fore period of 3.34 per 

 cent, in the preservative period 4.14 per cent, and in the after period 

 3.66 per cent. In this case the data are exactly the opposite in sig- 

 nificance from those of the preceding cases, the administration of the
