FURNEAUX, TOBIAS (1735-1781), English navigator, was born at Swilly, near Plymouth. He entered the royal navy, and was employed on the French and African coasts and in the West Indies during the latter part of the Seven Years' War (176o 63) . He served as second lieutenant of the "Dolphin" on her voy age round the globe (Aug. 1766–May 1768), and commanded the "Adventure" which accompanied Captain Cook on his second voyage. On this expedition Furneaux was twice separated from his leader (Feb. 8–May 19, Oct. 22, 1773–July 14, 1774, the date of his return to England). On the former occasion he explored a great part of the south and east coasts of Tasmania, and made the earliest British chart of the same. Most of his names here survive ; Cook, on his third voyage, named after him the islands in Banks strait, opening into Bass's strait, and the group now known as the Low Archipelago. After the "Adventure" was finally separated from the "Resolution" off New Zealand in Oct. 1773, Furneaux returned home alone, bringing with him Omai of Ulaietea. This first South Sea islander seen in the British Isles returned to his home with Cook in 1776-77. Fur neaux was made a captain in 1775, and commanded the "Syren" in the British attack of June 28, 1776, upon Charleston, South Carolina. His successful efforts to introduce domestic animals and potatoes into the South Sea islands are worthy of note. See J. Hawkesworth, An Account of the Voyages undertaken . . . by Captain Wallis, etc. (1773) ; also T. Furneaux's life by Rev. Henry Furneaux in the Dictionary of National Biography.
