(1788-1844) Traveller, son of Sir James Hall, an eminent man of science, was in the navy, and rose to be captain. He was one of the first to visit Corea, and wrote Voyage of Discovery to Corea (1818), also Travels in North America in 1827-28, a lively work which gave some offence in the U.S., Fragments of Voyages and Travels (1831-40), and some tales and romances. He was latterly insane.
