Zeelna, traversing in twelve hours only one-fifth of the visible hemisphere, while crossing in the same time 144 deg.

on the zodiac--twelve degrees per hour, or our Moon's diameter in two minutes and a half--was left behind by the stars; and fixing what I may call the ocular attention on her, she seemed to stand still while they slowly passed her; thus making their revolution perceptible to sense as it never is on Earth, for lack of a similar standard.

Caulna, rising in the west and moving eastwards, crossed the visible sky in five hours, and passed through the stars at the rate of 48 deg.

per hour, so that she seemed to sail past them like a golden cloudlet or celestial vessel driven by a slow wind.

It happened this night that she passed over the star Fomalhaut--an occultation which I watched with great interest through an excellent field-glass, but which lasted only for about half a minute.
