130 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



These data, in respect of the elimination of nitrogen, tend to show 

 a diminished absorption of the nitrogenous foods during the passage 

 of the food through the alimentary canal, which is opposite to the 

 conclusion derived from a study of the data of the first subject, and a 

 slight!} 7 increased absorption of the phosphatic elements of the food, 

 which is in harmony with the data obtained on subject No. 1. 



No. 3 W. S. 0. 



These data also will be considered only en bloc. Again there is seen 

 in the case of No. 3 a tendency on the part of the preservative to 

 increase slightly the percentage of water in the feces, that of the fore 

 period being 79, of the preservative period 80.72, and of the after 

 period 77.39. In respect of nitrogen eliminated, we see an agreement 

 with No. 2, the data showing a less complete absorption of the nitrog- 

 enous elements of the food during its passage through the alimentary 

 canal, the percentage of nitrogen excreted in the feces during the 

 fore period being 7.6, for the preservative period 9.3, and for the 

 after period 7.6. The percentage of phosphoric acid excreted in the 

 fore period is 25.4, in the preservative period 30.1, and in the after 

 period 24.7. 



These data show a very much larger absorption of the phosphatic 

 elements of the food in passing through the alimentary canal than in 

 the cases of Nos. 1 and 2. The preservative in this case, however, 

 does tend to decrease the amount of the phosphatic elements absorbed. 



No. 4 W. L. D. 



We find in the case of No. 4 again a slight tendency on the part of 

 the preservative to increase the amount of water in the feces, the per- 

 centage for the fore period being 78, for the preservative period 81.89, 

 and for the after period 81.04. The percentage of nitrogen eliminated 

 in the feces in the case of No. 4 is 8.4 for the fore period, 7.9 for the 

 preservative period, and 10.6 for the after period. Here there seems 

 to be a tendency on the part of the preservative to increase the absorp- 

 tion of the nitrogenous elements of the food from the alimentary 

 canal. The percentage of phosphoric acid eliminated in the fore period 

 is 30.7, for the preservative period 27.2, and for the after period 34.5. 

 In this instance the preservative has an apparent tendency to increase 

 the absorption of the phosphatic elements of the foods during their 

 passage through the alimentary canal. 



No. 5R. V. F. 



Again in this case we see a slight tendency manifest on the part of 

 the preservative to increase the percentage of water in the feces, the 

 quantity in the fore period being 77.55, in the preservative period 

 80.04, and in the after period 79.56. The percentage of nitrogen eliin-
