rough, and by no means minutely divided as in those cases 

 in which digestion had gone on well. The lungs were 

 very much congested. The posterior surface exhibited 

 dark patches and effused blood. From these well mark- 

 ed appearances, it was not thought necessary to kill a 

 sound rabbit for the purpose of comparing the results.

Dissection. The rabbits were not opened till ten o'clock 

 next morning. The stomach of the one which had taken 

 opium was very large, and slightly distended with air. 

 The cardiac and pyloric orifices exhibited a vegetable mass 

 of two different colours and states of digestion. At the 

 cardiac the vegetable was little if at all changed, of a dark 

 green colour, emitting a strong vegetable smell. The 

 whole was covered over with a coating of gastric juice. At 

 the pyloric extremity the vegetable had undergone a slight 

 change, the green colour had almost disappeared, and the 

 vegetable texture was less evident. The large intestines 

 were distended with vegetable matter, presenting a rough, 

 imperfectly concocted, appearance. The lungs were much 

 inflamed at their posterior surface ; the inferior parts of 

 the lobes were very much congested and discoloured. 



The sound rabbit, which was killed at the sametime as 

 the preceding, was now opened.
