Then he annexed its colonies and thereby extended his dominions to the Polar Ocean and the Ural Mountains.
He proved conclusively that any southern continent that might exist lay under the polar ice.
Also he showed that if such an antenna had its horizontal part swivelled round into various directions the current created in a distant receiver antenna varied with the azimuth, and when plotted out in the form of a polar curve gave a curve of a peculiar figure-of-8 shape.
This voyage of the middle of the 9th century deserves to be held in happy memory, for it unites the first Norwegian polar explorer with the first English collector of travels.
The polar regions travelled a little from west to east relatively to the equatorial, which lagged behind.
