238 EXPERIMENTAL PHYSIOLOGY. 



placed in a bath of physiological saline at about 33-35 C, contained 

 in a tank of suitable size and the intestines allowed to float out in 

 the saline. The pendular movements are very conspicuous and 

 the loops should be closely examined with the object of ascertaining 

 which of the muscular coats are contracting. If no peristaltic 

 waves are observed, they may be set up by pinching the intestine. 

 Observe closely the characteristics of these waves. 



The effect produced on the movements by stimulation of the 

 peripheral end of the splanchnic nerve is now studied. 



Records of the movements may be secured by the balloon 

 method already described for the oesophagus. 



Finally, if the animal is still in suitable condition, the effect 

 produced on the intestinal movements by injections into the jugular 

 vein of epinephrin (1-10,000 adrenalin chloride) and of atropine 

 are observed.
