and 77.48 per cent. The quantity of dry matter in the feces remains 

 the same for the three periods. The variations in weight, therefore, of 

 the feces are due solely to the differences in the percentages of water, 

 the amount of water being smallest in the fore period and largest in 

 the preservative period. 



The data for No. 5 are, as has before been explained, incomplete. 

 In so far as obtained they show an average daily excretion of 66 

 grams of moist feces in the fore period, 87 grams in the preservative 

 period, and 74 grams in the after period. The content of water in 

 the feces is 76.53 per cent, 77.88 per cent, and 77.43 per cent, respec- 

 tively, for the three periods. The quantity of dry matter excreted 

 is 16 grams, 19 grams, and 17 grams, respectively, for the three periods. 

 These data show a slight increase in the percentage of water in the 

 preservative period and a slight increase in the quantity of dry matter 

 excreted in the feces. 



The observations made on No. 6 show an average daily excretion 

 of 113 grams of moist feces in the fore period, 128 grams in the pre- 

 servative period, and 131 grams in the after period. The quantities 

 of water contained therein are 78.85 per cent, 79.23 per cent, and 80.47 

 per cent, respectively, for the three periods. The weights of dry 

 matter excreted in the feces are 24 grams, 26 grams, and 26 grams, 

 respectively, for the three periods. These data show a slight 

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

 period and another slight increase in the after period. The quantity 

 of dry matter excreted is slightly increased in the preservative and 

 after periods over the fore period. 



For No. 7 the average amount of moist feces excreted in the fore 

 period is 94 grams, and for the first, second, and third subperiods of 

 the preservative period 77 grams; the percentage of water and amount 

 of dry matter are slightly decreased in the preservative period. 

 By reason of the incompleteness of these data a comparison of those 

 secured is not of much value. 



No. 8 has an average daily excretion of moist feces in the fore 

 period of 107 grams, in the preservative period of 113 grams, and in 

 the after period of 144 grams. The percentages of water contained 

 in the feces are for the fore period 77.43, for the preservative period 

 78.08, and for the after period 83.37. The average daily quantities 

 of dry matter excreted are for the fore period 24 grams, for the pre- 

 servative period 25 grams, and A or the after period 24 grams. The 

 percentage of water in the feces is slightly increased in the preserv- 

 ative period and largely increased in the after period. The quantity 

 of dry matter excreted in the feces is slightly increased in the preserva- 

 tive period and is the same in the fore and after periods. 



No. 9 shows an average daily excretion of moist feces in the fore 

 period of 57 grams, in the preservative period of 59 grams, and in the
