The animals which feed upon poison have been already[1] mentioned. Some of them, which are harmless of themselves, become noxious if fed upon venomous substances. The wild boar of Pamphylia and the mountainous parts of Cilicia, after having devoured a salamander, will become poisonous to those who eat its flesh; and yet the danger is quite imperceptible by reason of any peculiarity in the smell and taste. The sala- mander, too, will poison either water or wine, in which it happens to be drowned; and what is more, if it has only drunk thereof, the liquid becomes poisonous. The same is the case, too, with the frog known to us as the bramble-frog. So nu- merous are the snares that are laid in wait for life! Wasps greedily devour the flesh of the serpent, a nutriment which renders their stings fatal; so vast is the difference to be found between one kind of food and another. In the country, too, of the Ichthyophagi,[2] as we learn from Theophrastus, the oxen are fed upon fish, but only when alive.
