At this period it was killed, and another also which had 

 taken food at the same time, that we might with more cor- 

 rectness compare the influence of opium, 



Dissection. Examination of the rabbit which had been 

 subjected to the effects of opium. The stomach was full, 

 containing a dark green vegetable mass, imperfectly con- 

 cocted. The contents of the large intestines did not ex- 

 hibit their ordinary changes ; they were rough, and rather 

 of a firm consistence ; the other viscera were healthy. 



The stomach of the sound rabbit was less distended than 

 the other ; but the mass was less perfectly digested, aris- 

 ing apparently from recent vegetable food which it had 

 taken. The contents of the large intestines were smooth, 

 soft, and completely changed in their vegetable character.
