302 Broughton on the Influence 



Experiment 3. 



A young rabbit was fed with parsley after a fast of fourteen 

 hours and an half, and the par vagum was immediately divided 

 at half-past eight a.m. At half-past twelve it was couched 

 upon its hind legs, and drawing its breath with difficulty. 

 About four, the difficulty of breathing having increased gra- 

 dually, the animal died. The parsley in the stomach was moist 

 and brown, with a covering of chyme, as before, about the car- 

 diac portion of the stomach. 



The oesophagus was full of bright-green chopped parsley, 

 and the other appearances did not differ from those of the 

 two former rabbits in any material degree. 



Experime:n"t 4. 

 After a fast of sixteen hours, a young rabbit was fed with 

 parsley, and the nerves were divided as before. Early in the 

 day the breathing seemed to be slightly oppressed, but towards 

 the evening it got better. The animal was found dead the next 

 morning. There was no redness of the stomach, and the ap- 

 pearance of the food resembled that of the last experiment, and 

 the oesophagus was full of bright-green chopped parsley. 



Experiment 5. 



The par vagum was divided on each side of the trachea of 

 an old horse, at eight p.m. Before the division a piece of tape 

 was passed loosely round each nerve so as to separate it from 

 its connexions. Instantly the animal seemed very much dis- 

 tressed, and made urgent efforts to draw his breath and vomit. 

 The nerves being divided, he staggered and fell down, rolled 

 about, and continued to breathe with great difficulty, and in an 

 hour he died. The inspirations were distinct and slow, and 

 the expirations sudden and strong. At first the heart's action 

 was increased, and latterly it became slow, feeble, and in- 

 distinct. The lungs were greatly turgescent. He died too 

 soon for any remarks on the state of the food in the stomach.

After fasting sixteen hours two young rabbits were fed with
