In 1769 the Scottish geographer Alexander Dalrymple, was translating Spanish letters found in the Philippines in 1762. He read Luis Váez de Torres' letter about a passage south of New Guinea. Dalrymple wrote a book, the "Historical Collection of the Several Voyages and Discoveries in the South Pacific Ocean" in 1770-1771. This book caused a lot of interest in the idea of an unknown continent. Dalrymple named the strait after Torres. This led Captain James Cook to go on another voyage into the South Pacific. Dalrymple was angry that it was Captain Cook and not him who was put in charge of the expedition which led in 1770 to the discovery of the east coast of Australia. In 1770 Cook sailed through the strait after sailing up the east coast of Australia. He landed on Possession Island and claimed all the land of Australia for Britain.
