If these live in one's house, they succeed in removing calamity. The same is the case with cockroaches. If fireflies and vultures and woodpigeons and bees enter a house and live in it, acts of propitiating the celestials should be performed. These are creatures of evil omen, as also ospreys. One should never give out the secrets of great men; one should never have sexual union with a forbidden woman. Nor should one ever have such union with the consort of a king or with women who are the friends of qucens.
