84 EFFECTS OF 



less frequent, and occasionally intermitted. At 

 the end of 35 minutes, the hind legs were pa- 

 ralysed, and he lay in a half sensible state. 

 At the end of 45 minutes he was less sensible, 

 the pupils of the eyes were dilated, the pulse had 

 fallen from 140 to 70 in a minute, and the in- 

 termissions were frequent. After this he became 

 quite insensible, convulsions took place, and, at 

 the end of 50 minutes from the beginning of the 

 experiment, he died. 



On opening the thorax immediately after death, 

 tremulous contractions of the heart were ob- 

 served; but not sufficient to maintain the circu- 

 lation. The stomach and intestines contained a 

 large quantity of mucous fluid, and their internal 

 membrane was highly inflamed. 



These experiments were repeated, and the 

 results, in all essential circumstances, were the 

 same. The symptoms produced were: 1. Pa- 

 ralysis of the hind legs, and afterwards of the 

 other parts of the body ; convulsions ; dilatation 

 of the pupils of the eyes ; insensibility : all of 

 which indicate disturbance of the functions of 

 the brain. 2. A feeble, slow, intermitting pulse, 

 indicating disturbance of the functions of the 

 heart. Where the heart has continued to act 

 after apparent death, I have never, in any one 

 instance, been able to prolong its action by means 

 of artificial respiration. 3. Pain in the region 

 of the abdomen ; preternatural secretion of mucus 

 .from the alimentary canal; sickness and vomiting 

 in those animals which are capable of vomiting ;
