The Viper has always been so remarkable for its venom, that the most remote antiquity made it an emblem of what is hurtful and destructive. Nay, so terrible was the nature of these creatures, that they were very commonly thought to be sent as executioners of divine vengeance upon mankind for enormous crimes, which had escaped the common course of justice.

We resolved to end our poison-enquiries by tasting the venomous liquor. According, having diluted a quantity of it, with a very little warm water, several of us ventured to put some of it upon the tip of our tongues. We all agreed, that it tasted very sharp and fiery, as if the tongue had been struck through with something scalding or burning. This sensation went off in two or three hours: and one gentleman, who would not be satisfied without trying a large drop undiluted, found his tongue swelled with a little inflammation and the soreness lasted two days. But neither his nor our boldness was attended with any ill consequence.

Venomous animals, when they bite or sting, inflict a wound, and instil into it a drop or more of liquor, which infects the fluid of the nerves, and by this means inflames the membranes: hereupon a swelling arises, sometimes to a degree of mortification, which spreads to the neighbouring parts.
