in which Death is produced, hy vegetable Poisons. igp 
At eight minutes after the poison was inserted, she lay on one 
side, motionless and insensible, the heart could not be felt, but 
the respiration had not entirely ceased. On opening into 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 in- 
spirations after the incision of the thorax was begun. On 
irritating the heart with the point of the scalpel, slight con- 
tractions took place in the fibres of the appendices of the 
auricles, but none in any other part. 
Exp. 23. The experiment was repeated on a rabbit. The 
symptoms produced were similar to those in the last experi- 
ment ; but the animal did not vomit, and the convulsive mo- 
tions were in a less degree : he died eleven minutes after the 
poison was inserted. On opening the chest, the heart was 
found to have entirely ceased contracting ; it was much dis- 
tended with blood ; and the blood in the cavities of the left 
side was of a scarlet colour. On irritating the heart with the 
point of the scalpel, the ventricles contracted, but not suffi™ 
ciently to restore the circulation. 
Exp. 24,. About a grain of the upas antiar was inserted into 
a wound in the side of rabbit. He was affected with symptoms 
similar to those before described, and died in ten minutes after 
the poison was applied. On opening the thorax immediately 
after death, the heart was found to have ceased contracting, 
and the blood in the cavities of the left side was of a scarlet 
colour. 
It appears from these experiments, that the upas antiar, when 
inserted into a wound, produces death (as infusion of tobacco 
does when injected into the intestine) by rendering the heart
