this quantity there appear in the feces in the fore period 3.82 grams 

 and in the preservative period 2. 74 grams. Expressed as percentage of 

 the total amount of fat in the food, No. 10 excreted 3.92 per cent 

 during the fore period and 2.99 per cent during the preservative period. 

 Owing to illness, No. 10 was absent from the table during the after 

 period. 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 average daily quantity of fat in the food 

 in the fore period is 97.67 grams, in the preservative period 95.03. 

 grams, and in the after period 93.26 grams. Of this quantity there 

 appear in the feces of the fore period 3.49 grams, in the preservative 

 period 3.04 grams, and in the after period 2.64 grams. Expressed in 

 percentages of the total quantity of fat in the food there was excreted 

 in the feces of the fore period 3. 58 per cent, of the preservative period 

 3.20 per cent, and of the after period 2.83 per cent. These data show 

 a tendency on the part of the preservative to increase the absorption 

 of the fatty substances from the alimentar} 7 canal and diminish the 

 quantity excreted in the feces. This tendency is continued in the 



after period. 



No. 12. 



The average daily quantity of fat in the food of No. 12 in the fore 

 period is 117.22 grams, in the preservative period 119.10 grams, and 

 in the after period 113.74 grams. Of this quantity there appear in 

 the feces of the fore period 5.03 grams, of the preservative period 2.55 

 grams, and of the after period 3.11 grams. Expressed as percentages 

 of the total quantity of fat in the food there appear in the feces of the 

 fore period 4.29 per cent, of the preservative period 2.14 per cent, and 

 of the after period 2.73 per cent. These data show a very marked 

 tendency on the part of the preservative to increase the absorption of 

 the fatty substances from the alimentary canal and to decrease the 

 quantity appearing in the feces. This tendency is only partially cor- 

 rected during the after period.
