Many are the Experiments I could relate to evince the Truth of this Reasoning concerning the Viperine Venom, which do entirely agree with those made by S^r _Redi_, whose Judgment and Sincerity in Observations of this Nature no Body ever called in Question, till Monsieur _Charas_ having espous’d a Notion, that this Poison does not lie in the Yellow Liquor of the Gums, but in the enraged Spirits of the Viper, rais’d new Difficulties about the Success of some Trials made in _France_, endeavouring thereby to invalidate the Force and Authority of those made in _Italy_. I shall therefore, in order to put this Matter out of all doubt, mention Two or Three Experiments made by Dr. _Areskine_, when at _Paris_, that it may appear how defective those of Mr. _Charas_ are, and that the Difference of the Climate does not (as some began to imagine (16)) make any considerable Alteration in the Effects of this Venom, or its manner of Killing. First then, having got a large Female Viper, he made it to Bite Six Pigeons, one after another; the First and Second that were bit, died within about half an Hour, one a little Time before the other; the third liv’d about two Hours; the Fourth seem’d to be very sick, but recovered; the Fifth and Sixth were no more hurt than if they had been prick’d with a Pin or Needle. Then he cut off the Head of a brisk Viper, and let it lie twenty four Hours, with the Fangs of which he wounded One Pigeon in the Breast, and another in the Thigh, which both expired as soon after, as if they had been biten by a living Viper. After this, having got a great many Vipers together, he made them bite upon a peice of Glass of a Cylindrical Figure, by this means preserving the Yellow Juice which they emitted, and slightly wounding two Pigeons, he first let the Bleeding be stopt, then put some of this Liquor into the Wounds, upon which both the Pigeons died about two Hours after. The same Ingenious Person tells me, that Monsieur _du Verney_ made not only These, but also several other Experiments of the same Nature, in the _Royal Acamy_, with the like Success. These Proofs are so convincing and full, that no one, I think, can desire more; but they will receive yet a farther Confirmation from the _Apparatus_ or Mechanism of the Organs, with admirable Nicety contrived for the Discharge of this Venom, of which more by and by.
