Increasing Quantities of Fat in Diet on Metabolism in Dogs. 283 



same, at the same time the quantity of water differs somewhat con- 

 siderably. 



Table X. Normal Dog 2. Showing the Influence of an Increasing- 

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

 the Faeces. 



The percentage of water in this dog was less than the percentage on? 

 the corresponding diet in the first normal dog, being only 63'26 and 

 64-60 per cent. On increasing the fat in the diet, the quantity of 

 faeces, as in the former normal dog, increased, and the total water 

 eliminated also increased. The percentage of water, however, de- 

 creased, so that though the increase of fat in the diet caused in this 

 dog, as in the former, an increased elimination of water in the faeces, 

 this was due to an increased quantity of faeces passed, and not due to 

 any increase of the fluid constituent thereof. 



We now come to the dog in which the large intestine was partially 

 removed, Table XI, and in which, as we have already seen, there was 

 a dilatation of the rectum. In spite of this latter condition the absorp- 

 tion of this dog differed somewhat from the absorption of the normal 

 dog. In this dog, during the three periods analysed, the quantity of 

 faeces fluctuated on different days, and during the first two periods,
