EAGLE-stone, in Natural History, is a stone by the Greeks called atites, and by the Italians 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. Bausch has an express Latin treatise on the subject. See ÆTITES.
