EAGLE-stone, in Natural History, is a stone by the Greeks called aites, and by the Italian pietra d'aquila, as being supposed to be sometimes found in the eagle's nest. It is of famous traditional virtue, either for forwarding or preventing the delivery of women in labour, according as it is applied above or below the womb. Matthiolus tells us, that birds of prey could never hatch their young without it, and that they go in search of it as far as the East Indies. Bauch has an express Latin treatise on the subject. See ÆTITES.
