Francisco Benito Jero-Nimo Feyjoo Y Montenegro, a Spanish reformer, born probably at Car-damiro, Oct. 8, 1676, died in Oviedo, May 16, 1764. He was a Benedictine monk, and became professor of divinity at Oviedo, abbot, and eventually general of the Benedictine order. He resided the greater part of his life in the monastery at Oviedo, devoted to literary, philosophical, and scientific labors. He opposed the philosophical system then taught in Spain, maintaining Bacon's principle of induction in the physical sciences, and ridiculing the prevailing fallacies in regard to astronomy and astrology. He published his dissertations under the title of Teatro crltico universal, b dis-cursos varies en todo genero tie materia, para desengaho tie errores comunes (l73G-'42), and continued them under the title of Cartas erutli-tas (1742-'G0). His works have gone through many editions, and selections from them were translated into French by D'Hermilly (Paris, 1745), and into English by John Brett (London, 1770-'80).
