Derby House, Canon Row, Westminster. A stately house, described by Stow, in 1598, as "now in building, by William Earl of Derby ; "t surrendered to Parliament in the reign of Charles I., and made use of by the members of the House for committee meetings and State purposes. John Pym died here, (1643), and here his body was publicly exposed "to confute the lying assertions of his enemies, that it had been eaten with lice." J Here, in the early part of Charles II.'s reign, was the office of the Lord High Admiral. § The name still lingers in Derby-court.
