13 c.c. of fluid were recovered from the intestine. It was alkaline in reaction and gave 

 a fair precipitate with silver nitrate. It did not contain any appreciable amount of mucin. 

 Weight of the intestines 108 grams.

An endeavour was made to test the further question whether the 

 absorption of peptone involved activity of the cells; in this Halli- 

 burton (5) and Miss Cullis took part. Their experiments showed that 

 such an activity took place in the experiments, it is not however clear 

 that the activity was greater than during the absorption of a corre- 

 sponding quantity of the normal saline in which the peptone was 

 dissolved. 



We may now pass to the other phase of the question, namely the 

 investigation of what happens when the fluid passes from the blood 

 to the lumen of the intestine. This of course is a matter of great 

 interest to the pharmacologist, and inasmuch as it was performed 

 from his point of view, the presence of a strong solution of magnesium 

 sulphate in the intestine was used for the purpose of evoking a flow 

 of fluid. The result of the experiment seemed to show that in this 

 case the activity of the cells was not invoked but that the action of 

 the magnesium sulphate was a purely mechanical one. 



Dog of 14 kilos weight. Intestines washed out with warm saline. Artificial respiration 

 maintained throughout the experiment.
