VEGETABLE POISONS. 67 



EXPEBIMENT XXIX. 



I made the experiment a third time on a rabbit, 

 drawing the ligature very tight. At the end 

 of 45 minutes, he continued perfectly well, 

 and the ligature was removed. I watched him 

 for three quarters of an hour afterwards, but 

 there were no symptoms of his being affected 

 by the poison. On the following day he died, 

 but this I attribute to the mechanical injury 

 done to the limb and sciatic nerve, 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 

 20 minutes, if no ligature 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 experiments 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 pre- 

 venting the action of the poison. It is not to be 

 wondered at, that the ligature should sometimes
