= Henze IV, p.668ff (on James Clark Ross) and p.677ff (on John Ross); Cat. Nat. Maritime Mus. 850: "As a result of the failure of his voyage in 1818, the Admiralty refused to support Ross in a second attempt. It was not until 1829 that the assistance of Felix Booth, the Sheriff of London, enabled him to set out in the small paddle-steamer Victory, with his nephew, James Clark Ross, as second-in-command. The expedition survived four winters beset in the Arctic, during which James Clark Ross discovered the northern magnetic pole on May 31, 1831. John Ross was knighted on the expedition's return."
