The more light there is the blinder this creature becomes; as those who gaze most at the sun become most dazzled.--For Vice, that cannot remain where Virtue appears. THE PARTRIDGE. This bird changes from the female into the male and forgets its former sex; and out of envy it steals the eggs from others and hatches them, but the young ones follow the true mother. This bird gives sight to its blind young ones by means of celandine. THE OYSTER.--FOR TREACHERY. This creature, when the moon is full opens itself wide, and when the crab looks in he throws in a piece of rock or seaweed and the oyster cannot close again, whereby it serves for food to that crab. This is what happens to him who opens his mouth to tell his secret. He becomes the prey of the treacherous hearer. THE BASILISK.--CRUELTY. All snakes flie from this creature; but the weasel attacks it by means of rue and kills it. This carries instantaneous death in its fangs; and, that it may not hear the charmer it stops its ears with its tail. This creature entangles itself in the legs of the elephant which falls upon it, and so both die, and in its death it is avenged. She, in pairing opens her mouth and at last clenches her teeth and kills her husband. Then the young ones, growing within her body rend her open and kill their mother.
