Edmond Halley was already a well-known astronomer, mathematician and natural philosopher when, in 1698, he took command of His Majesty's Ship Paramore. The purpose of Halley's fist two voyages was to test his geomagnetical theories; in the third voyage he investigated tidal phenomena. These voyaged, which received royal approval, support from the Navy, and sponsorship by the Royal Society have been regarded as the first sea journeys undertaken for purely scientific purposes. In this book the journals of Halley's three voyages are published in full from manuscripts now in the British Library. The work also contains well over one hundred documents relating to the voyages, many published for the first time. The two most original but now rare maps arising from these journeys, the Atlantic Chart and the Channel Chart (in two sheets), are reprinted in facsimile for the portfolio.
