In those latitudes where day and night during the greater part of the year are not even approximately equal, the black and green semicircles are so enlarged or diminished by mechanical means, that the hour of the day or night is represented as accurately as on the Equator itself.
The examination of this establishment occupied us for two or three hours, and when we remounted our carriage it seemed to me only reasonable that Eveena should be weary both in mind and body.
