284 Prof. Y. Harley. Influence of Removal of Large Intestine and 



there was occasionally an interval of a day without any faeces being 

 passed. In consequence of this constipation one would .expect the 

 percentage of water to be small ; it is seen that in this dog the per- 

 centage of water during the first period was 50*96, and with a

 in this dog, by increase of fat in the diet, one got not only an increase 

 in the total quantity of water eliminated by the faeces but also an

 of an Increasing Quantity of Fat in the Diet on the Quantity of 

 Faeces and the Water of the Faeces. 



We now come to the dogs in which the total removal of the large 

 intestine is carried out. We have in Table XII two groups of results, 

 which represent two periods during which the dog received 9*71 grams 

 of fat, and two periods in which 29*71 grams of fat were given. As in 

 the normal dogs, we have here also an increase in the quantity of faeces, 

 produced by increasing the quantity of fat, and also an increase in the
