Black Island and Brown Island. To suppose them to be part of a line of continuous land was a very natural mistake.
Ross broke through the pack ice into an unknown sea: he laid down many hundreds of miles of mountainous coast-line, and (with further work completed in 1842) some 400 miles of the Great Ice Barrier: he penetrated in his ships to the extraordinarily high latitude of 78° 11′ S., four degrees farther than Weddell. The scientific work of his expedition was no less worthy of praise. The South Magnetic Pole was fixed with comparative accuracy, though Ross was disappointed in his natural but "perhaps too ambitious hope I had so long cherished of being permitted to plant the flag of my country on both the magnetic Poles of our globe."
Before all things he was at great pains to be accurate, both in his geographical and scientific observations, and his records of meteorology, water temperatures, soundings, as also those concerning the life in the oceans through which he passed, were not only frequent but trustworthy.
When Ross returned to England in 1843 it was impossible not to believe that the case of those who advocated the existence of a South Polar continent was considerably strengthened. At the same time there was no proof that the various blocks of land which had been discovered were connected with one another. Even now in 1921, after twenty years of determined exploration aided by the most modern appliances, the interior of this supposed continent is entirely unknown and uncharted except in the Ross Sea area, while the fringes of the land are only discovered in perhaps a dozen places on a circumference of about eleven thousand miles.
In his Life of Sir Joseph Hooker, Dr. Leonard Huxley has given us some interesting sidelights on this expedition under Ross. Hooker was the botanist of the expedition and assistant surgeon to the Erebus, being 22 years old when he left England in 1839. Natural history came off very badly in the matter of equipment from the Government, who provided twenty-five reams of paper, two botanizing vascula and two cases for bringing home live plants:
