OF SERPENTS. I23 



brought, and as the volatile alkali appeared to have 

 been of fome ufe in the laft experiment, it was de- 

 termined to try it firll: and this experiment, as well 

 as feveral of thofe already related, was conducted by 

 my friend Dr. Moir with attention and accuracy. A 

 dog was accordingly bitten in the ufual place, and 

 the volatile alkali given as in the preceding experi' 

 ment : the dog was dead in eighteen minutes. 



EXPERIMENT X. 



To a dog bitten in the fame place. Immediately 

 after the former, that we might have the m.eans of 

 afcertaining the effects of the remedy, nothing was 

 given, he died in eighteen minutes. 



EXPERIMENT XI. 



^•'Observing in the feventh volume of the medical 

 fa61s publifhed by Dr Simmons, that Cayenne pepper 

 was a powerful remedy for a vegetable poifon obtained 

 from the roots of the Jatropha Manihot, or bitter Cajfada, 

 I determined to make trial of it. Po a dog bitten in 

 the ufual manner, five grain pitls of the pepper were 

 given, and the wounded limb was w^aflied with an in- 

 fufion of it in warm water. Thefe pills had been re- 

 peated four times in the fpace of an hour, when the 

 dog died. 



EXPERIMENT XII. 



A YOUNG puppy was now bitten in the ear, and ex- 

 actly half a minute after the ear was cut off. The 

 wound made by the knife bled treely. The dog con- 

 tinued lively for fome time, but in half an hour, he 

 began to droop, and in half an hour more, died. It 

 is obferved by Fontana, and he fufficiently w^ell 

 accounts for it, that on biting the ears of animals, a 

 drop of venom colle6ts on the ear, at the hole made 

 by the tooth : this was very remarkable in the experi- 

 ment now related : a quantity of venom, like a large 

 drop of } ellow fecum, collected on the ear, and trick- 

 led to the ground.
