The air made but slight resistance.

The aeronef was like an aerostat, which drifts with the fluid masses in which it is plunged.
Is the domain of the southern pole a continent or an archipelago?
Or is it a palaeocrystic sea, whose ice melts not even during the long summer?
We know not.

But what we do know is that the southern pole is colder than the northern one--a phenomenon due to the position of the earth in its orbit during winter in the antarctic regions.
During this day there was nothing to show that the storm was abating.
It was by the seventy-fifth meridian to the west that the "Albatross" crossed into the circumpolar region.

By what meridian would she come out--if she ever came out?
As she descended more to the south the length of the day diminished.
Before long she would be plunged in that continuous night which is illuminated only by the rays of the moon or the pale streamers of the aurora.

But the moon was then new, and the companions of Robur might see nothing of the regions whose secret has hitherto defied human curiosity, There was not much inconvenience on board from the cold, for the temperature was not nearly so low as was expected.
It seemed as though the hurricane was a sort of Gulf Stream, carrying a certain amount of heat along with it.
Great was the regret that the whole region was in such profound obscurity.
