after period of 109 grams. The percentages of water contained in the 

 feces are 68.73 for the fore period, 67.51 for the preservative period, 

 and 73.87 for the after period. The quantities of dry matter excreted 

 in the feces are 18 grams for the fore period, 19 grams for the pre- 

 servative period, and 28 grams for the after period. These data 

 are apparently abnormal, as indicated by the large increase in the 

 feces excreted during the after period. 



The average daily quantities of moist feces excreted by No. 10 

 are 71 grams for the fore period, 108 grams for the preservative 

 period, and 104 grams for the after period. The percentages of mois- 

 ture contained therein are 75.35 for the fore period, 79.38 for the 

 preservative period, and 74.86 for the after period. The quantities 

 of dry matter in the feces are 17 grams for the fore period, 22 grams 

 for the preservative period, and 26 grams for the after period. In 

 this case there is a marked increase in water content in the pre- 

 servative period, accompanied by a considerable increase in dry 

 matter, which continues in the after period, through the water content 

 markedly decreases. 



The data for No. 11 show an average daily quantity of moist 

 feces in the fore period of 112 grams, in the preservative period of 

 126 grams, and in the after period of 105 grams. The percentages of 

 water contained therein are 75.53 for the fore period, 77.19 for the 

 preservative period, and 76.36 for the after period. The average 

 quantity of dry matter excreted in the feces during the fore period 

 is 28 grams, during the preservative period 29 grams, and during the 

 after period 25 grams. In this instance both the quantity of water 

 in the feces and the amount of dry matter excreted are largest in the 

 preservative period. 



The data for No. 12 show a daily excretion of 84 grams of moist feces 

 for the fore period, 97 grams for the preservative period, and 75 grams 

 for the after period. The percentages of moisture contained therein 

 are 71.62 in the fore period, 74.34 in the preservative period, and 73.36 

 in the after period. The average daily quantities of dry matter 

 excreted are for the fore period 24 grams, for the preservative period 

 25 grams, and for the after period 20 grams. In this case also the 

 percentage of water in the feces and the amount of dry matter excreted 

 are greatest in the preservative period.

In the summary for Nos. 1 to 6, inclusive, who received sodium 

 sulphite, the following results are obtained : The average daily quan- 

 tity of moist feces excreted in the fore period is 82 grams, during the 

 first, second, and third subperiods of the preservative period 103 

 grams, and during the after period 85 grams. The average percentage
