The sting of the asp takes deadly effect by causing torpor and drowsiness. Of all serpents, injuries inflicted by the asp are the most incurable; and their venom, if it comes in contact with the blood or a recent wound, produces instantaneous death. If, on the other hand, it touches an old sore, its fatal effects are not so immediate. Taken internally, in however large a quantity, the venom is not injurious,[1] as it has no corrosive properties; for which reason it is that the flesh of animals killed by it may be eaten with impunity.

I should hesitate in giving circulation to a prescription for injuries inflicted by the asp, were it not that M. Varro, then in the eighty-third year of his age, has left a statement to the effect that it is a most efficient remedy for wounds inflicted by this reptile, for the person stung to drink his own urine.
