Alleon, Dulac John Lewis

was born at Lyons, and fora long time was a practitioner there at the bar. He united, however, a knowledge of the law with a taste for natural history, which last induced him to retire from business to St. Etienne in Forez, where he could more conveniently pursue his inquiries into the properties of fossils and mineralogy in general. He accordingly published “Memoires pour servir a l'histoire naturelle du Lyonnois, Forez, et Beaujolais,” 2 vols. 12mo, 1765; and “Melanges d'histoire naturelle,” which first appeared in 1763, 2 vols. 12mo, but afterwards there was a new edition in 6 vols. He died at St. Etienne in 1768. ²
