Leland, Thomas D.D., an English divine, was born at Dublin in 1722, and was educated at Trinity College in that city. He became senior fellow of the college, and was made a professor of poetry there in 1763; afterwards vicar of Bray, and later chaplain to the lord lieutenant of Ireland. He died in 1785. Leland was a profound scholar and a most eloquent preacher. He published the Orations of Demosthenes, Latin version and notes (London, 1754, 2 vols. 12mo), in conjunnction with Dr. John Stokes: — the Orations  of Demosthenes, in English (1756-61-70, 3 vols. 4to; last ed. 1831, 12mo): — Hist. of the Life and Reign of Philip, King of Macedon (1758, 2 vols. 4to; last ed. 1820, 2 vols. 8vo): — Dissertation on the Principles of Human Eloquence, etc. (1764, 4to), elicited by bishop Warburton's Discourse on the Doctrine of Grace: answered (anonymously) by Hurd, on behalf of Warburton, in a very petulant letter. Answer to a letter to him, etc., 1764, 4to. This is a reply to Hurd. Leland answered for himself, and. in the opinion of all the world, completely demolished his antagonist.
