Among the birds that afford us remedies against serpents, it is the vulture that occupies the highest rank; the black vulture, it has been remarked, being less efficacious than the others. The smell of their feathers, burnt, will repel serpents, they say; and it has been asserted that persons who carry the heart of this bird about them will be safe, not only from serpents, but from wild beasts as well, and will have nothing to fear from the attacks of robbers or from the wrath of kings.
