VEGETABLE POISONS. 61 



EXPERIMENT XXII. 



A small quantity of the upas antiar, prepared 

 as before, was inserted into a wound in the thigh 

 of a young cat. She appeared languid in two 

 minutes after the poison was inserted. The 

 symptoms which took place did not essentially

 be felt, but the respiration had not entirely 

 ceased. On opening the thorax, I found the 

 heart to have ceased contracting. It was much 

 distended with blood: and the blood in the 

 cavities of the left side was of a scarlet colour. 

 There were two full inspirations after the in- 

 cision of the thorax was begun. On irritating 

 the heart with the point of the scalpel, slight 

 contractions took place in the fibres of the ap- 

 pendices of the auricles, but none in any other 

 part. 



EXPERIMENT XXIII. 



The experiment was repeated on a rabbit. 

 The symptoms produced were similar to those in 

 the last experiment ; but the animal did not 

 vomit, and the convulsive motions were less in 

 degree. He died 11 minutes after the poison was
