The author, who discovered the north magnetic pole on an earlier expedition, here describes his Antarctic voyages, in part in search for the south magnetic pole, in the ships Erebus and Terror. 'Ross' experience, daring and good luck combined to provide the first detailed, close-up and prolonged examination of Antarctica. . . He penetrated 7 degrees further south than Cook and 4 degrees further south than Weddell. Scott, Shackleton, Amundsen and Byrd all followed in his large footsteps. . . These men were heroes.' Joseph Hooker was aboard as naturalist and John Edward Davis was responsible for many of the illustrations.
