CHARLES, Esq. a very singular person, whose great erudition was so concealed by his modesty, that his name is known to very few, though his publications are many. He was born in 1678, and became distinguished in 1724 by A Treatise of Fluxions, folio; the only work to which he ever set his name. In 1710, came out a small 4to pamphlet of 19 pages, entitled, A new and easy Method to find out the Longitude, from observing the Altitudes of the Celestial Bodies: and in 1723, The Moon, a Philosophical Dialogue; tending to shew, that the moon is not an opaque body, but has original light of her own. During a long course of years, the management of the late Royal African Company lay in a manner wholly upon Mr Hayes, he being annually either sub-governor or deputy-governor; notwithstanding which, he continued his pursuit after general knowledge. To a skill in the Greek and Latin as well as modern languages, he added the knowledge of the Hebrew: and published several pieces relating to the translation and chronology of the Scriptures. The African Company being dissolved in 1752, he retired to Down in Kent, where he gave himself up to study. May 1753, he began to compile in Latin his Chronographia Asiae et Aegyptiaca, which he lived to finish but not to publish; which, however, was published afterwards. August 1758, he left his house in Kent, and took chambers in Gray's Inn, where he died, Dec. 18, 1760, in his 82d year. The title of his posthumous works runs thus: Chronographiae Asiae et Aegyptiacae Specimen; in quo, 1. Origo Chronologic LXX Interpretum incofugitur. 2. Con- spefus totius operis exhibetur, 8vo.
