INDIVIDUAL DATA. 



The average weight of the moist feces for No. 1 for the fore period 

 is 66 grams, containing 69.68 per cent of water and 20 grams of dry 

 matter. For the preservative period the average weight of the feces 

 is 89 grams, containing 79.95 per cent of moisture and 18 grams of dry 

 substance. For the after period the average weight of the moist feces 

 is 37 grams, containing 65.14 per cent of water and 13 grams of dry 

 substance. These data show a very complete absorption of the ingested 

 material throughout and consequently a small excretion of feces. There 

 is a marked increase in the water content of the feces in the preserva- 

 tive period and a slight decrease in the quantity of dry matter 

 excreted. In the after period there is a decrease in the quantity of 

 water in the feces, as compared with the fore period, and a marked 

 decrease in the quantity of dry matter excreted. 



The data for No. 2 show in the fore period that the average weight 

 of the feces is 87 grams, containing 68.74 per cent of water and 27 

 grains of dry matter. For the preservative period the mean quantity 

 of moist feces is 99 grams, containing 69.72 per cent of water and 30 

 grams of dry matter. For the after period the average quantity of 

 feces excreted is 100 grams, containing 73.03 per cent of water and 

 27 grams of dry matter. These data show little change in the fecal 

 excretion during the three periods of observation. There is a slight 

 increase in the percentage of water in the preservative period and a 

 still greater increase in the after period. The quantity of dry matter 

 in the feces during the preservative period is increased by 3 grams 

 per day, while the quantity of dry matter in the fore period and after 

 period is the same. 



In the case of No. 3 there is found in the feces during the fore period 

 55 grams of moist feces daily, containing 64.62 per cent of water and 

 20 grams of dry matter. During the preservative period the average 

 daily excretion of moist feces is 78 grams, containing 65.49 per cent of 

 water and 27 grams of dry matter. In the after period the average 

 daily quantity of feces is 60 grams, containing 68.38 per cent of water 

 and 19 grams of dry matter. In this case the percentage of water in 

 the feces does not vary much during the period of observation, though 

 it is slightly increased in the preservative period and again increased 

 in the after period. The quantity of dry matter in the feces is very 

 markedly larger in the preservative period, the increase amounting 

 to 35 per cent, while the quantity of dry matter excreted during the 

 after period is almost exactly the same as in the fore period. 



In the case of No. 4 the average quantity of moist feces excreted daily 

 is 96 grams in the fore period, 121 grams in the preservative period, and 

 110 grams in the after period. The quantities of water in the feces 

 for the three periods, respectively, are 73.54 per cent, 79.02 per cent,
