Tlie following table gives the results of one of the series of ex- 

 periments made. 



TABLE VII. 



This series of experiments shows the quantity of enterokinase to 

 decrease gradually dotnward, a result ayreehuj ivith that obtained 

 by ÜHErowALNiKow, Delezenne, Prodin and Falloise. 



I shall not discuss the experiments here, which show that in the 

 digestion of albumen by trypsin the presence of agar has a retarding 

 influence, nor the influence which the time during which the agar 

 has been in contact with the intestinal mucous membrane, has on 

 the transition of the enterokinase. These questions will be further 

 discussed in a more explicit account. 



One experiment remains to be mentioned, showing how the 

 enterokinase diffused into the agar, distributes itself over agar and 

 water, after the agar has been cut up and mixed with water. 



5 cc. of liquid agar are mixed with 2 cc. of watery extract of the intestinal 

 mucous membrane. Of this mixture 2X3 cc. are taken and poured into the 

 above mentioned cylindrical tubes. When the agar has become solid it is cut 

 fine and mixed each time with 2 cc. of water. The mixture remains for an hour 

 exposed to the temperature of the body in order to enable the agar to give up 

 enterokinase. 



After cooling down it is filtrated, twice 1 cc. is taken and mixed with 2 cc. of 

 inactive pancreatic juice. In both mixtures I and II albumen tubes are placed. 



Besides this experiment another one identical with it, is made; only instead of 

 5 cc. of agar, 5 cc. of water are taken of course. Gutting up is out of the ques- 

 tion here. The quantities, however, remain the same.
