Beroldingen, Francis De

, an eminent mineralogist, was born at St. Gall, Oct. II, 1740, and died March 8, 1798. He was a canon of Hildesheim and Osnaburgh, a member of several literary societies, and had travelled into various countries, to investigate the nature of the soil, the structure of mountains, and their mineral productions. By this means he accumulated a great stock of information which has given a value to his works, notwithstanding his inclination to hypotheses, and the indulgence of certain prejudices. All his works are in German. Their subjects are, 1. “Observations, doubts, and questions on Mineralogy, &c.” 2 vols. 1778 1793, 8vo. 2. "Observations made during a tour to the quicksilver mines of |

the Palatinate, &c.“Berlin, 1788, 8vo. 3.” The Volcanos of ancient and modern times considered physically and mineralogically,“Manheim, 1791, 8vo. 4.” Anew theory on the Basaltes,“printed in Crell’s supplement to the annals of Chemistry. 5.” A description of the fountain of Dribourg," Hildesheim, 1782, 8vo. ¹
