in which Death is produced by vegetable Poisons. 
Peep. 28. I repeated the last experiment with this differ- 
ence, that after having applied the poison, I made the ligature 
as tight as I could draw it. I removed the ligature at the end 
of an hour and twenty minutes, but the animal was not at all 
affected either before or after the removal of the ligature, and 
on the following day he had recovered the use of the limb. 
Exp . 29. I repeated the experiment a third time, drawing 
the ligature very tight. At the end of forty-five minutes, the 
animal continued perfectly well, and the ligature was re- 
moved. I watched him for three quarters of an hour after- 
wards, but there were no symptoms of his being affected by 
the poison. On the following day the rabbit died, but this 1 
attribute to the injury done to the limb and sciatic nerve by 
the ligature, as there was the appearance of inflammation in 
the parts in the neighbourhood of the ligature. 
These three experiments were made with the greatest care. 
From the mode, in which the poison was applied, from the 
quantity employed, and from my prior experience, I should 
have entertained not the smallest doubt of the poison taking 
effect in every instance in less than twenty minutes, if no liga- 
ture had been applied. In two of the three, the quantity of 
woorara was more than had been used in any former experi- 
ments. 
I have not judged it necessary to make any more experi- 
ments, with the ligature on the limb, because the numerous 
experiments of the Abbe Fontana on the ticunas, coincide 
in their results, with those, which have just been detailed, 
and fully establish the efficacy of the ligature, in preventing 
the action of the poison. It is not to be wondered at, that the 
ligature should sometimes fail in its effects, since these must
