similar results, so that we must come to the conclusion, either, that the line of uniform temperature of the ocean in these meridians is nearly half a degree higher temperature than at the places we had previously crossed, or that some inexplicable change to that amount had taken place in our standard thermometer, and which the comparison with the several other thermometers gave me some reason to suppose had occurred. The annexed abstract from the meteorological journal of the Erebus will furnish every information respecting the climate of these regions during the month of March. The mean position of the mercury in the barometer in the higher latitudes of the Antarctic regions was nearly an inch lower than in other parts of the world, and constitutes a most remarkable and interesting phenomenon in terrestrial physics, which I shall have occasion to notice more fully hereafter.
