We go on to read of swift little beasts called _Pyrigoni_ who are generated from fire and live in it, of salamanders who extinguish flames, of the remedies used by the tortoise against snakes, of the chastity of doves whose marriages never result in divorce, and of the incontinence of the partridge.[1447] Also of the jealousies of certain animals like the stag which hides its right horn, the lizard who devours its cast-off skin, and the mare who eats the hippomanes from its colt, lest men obtain these precious substances.[1448] Of the care taken by storks, herons, and pelicans of their aged parents.[1449] How the swallow by the virtue of an herb gives sight to its young who are born blind, and how a hoopoe found an herb whose virtue dissolved the mud with which the caretaker of a building had plugged up the hole in the wall which it used for its nest.[1450] How the lion and basilisk fear the cock, and of a lake without fish in a place where the cocks do not crow.[1451] How elephants venerate the waxing moon; how the weasel eats rue when about to fight the snake; and of the jealousy of the hedgehog and lynx, the latter concealing his precious urine, the other watering his own hide when he is captured in order to spoil it.[1452] How the Indians fight griffins when collecting gold.[1453] How the presence of a cock aids a woman’s delivery.[1454] Of unnamed beasts in Libya who know how to count and leave an eleventh part of their prey untouched.[1455] That the sea dragon is easily captured with the left hand but not with the right.[1456] Dragons know the force of herbs and cure themselves with some and increase their venom with others.[1457] How dogs, cows, and other animals sense a famine or plague beforehand.[1458] How the Egyptians by their magic charm birds from the sky and snakes from their holes.[1459] When it rains in Egypt, mice are born from the small drops and plague the country. Traps and fences and ditches are of no avail against them, as they can leap over trenches and walls. Consequently the Egyptians are forced to pray God to end the calamity,[1460]—an interesting variant on the Old Testament account of the plagues of Egypt.
