In normal dog 1, Table IX, are placed together the analyses of the 

 faeces, as influenced by the increase of fat in the diet. The fat is seen 

 iere to cause not only an increase in the quantity of faeces, but also an 

 increase in the total quantity of water excreted in the faeces. While 

 we saw that increasing the fat in the normal dog's diet caused a decrease 

 in the quantity of urine passed, we find here that it causes an increase 

 in the quantity of water eliminated by the faeces, being on the first diet 

 12-79 grams, then 13*79 grams, and on the diet rich in fat no less than 

 14'32 grams. The percentage of water in the total faeces, however, 

 decreases with the increased quantity of fat, as it falls from an average 

 of 70-98 to 67-85 and 67*87 per cent. Thus the increased quantity of 

 water eliminated by the faeces is due to the increased quantity of 

 faeces, and not to an increased percentage of water present.

 Quantity of Fat in the Diet on the Quantity of Faeces and the 

 Water contained in them. 



In dog 2, Table X, we have two periods in which the quantity of 

 fat remained constant. As far as the quantity of faeces was concerned 

 we found during these two periods the quantity pretty nearly the
