The Balance follows the Virgin. Its scales, marked by two stars of
second magnitude, are situated a little to the East of Spica.
We next come to the eighth constellation of the Zodiac, which is one of
the most beautiful of this belt of stars. Antares, a red star of first
magnitude, occupies the heart of the venomous and accursed Scorpion. It
is situated on the prolongation of a line joining Regulus to Spica, and
forms with Vega of the Lyre, and Arcturus of the Herdsman, a great
isosceles triangle, of which this latter star is the apex.
The Scorpion, held to be a sign of ill luck, has been prejudicial to the
Archer, which follows it, and traces an oblique trapezium in the sky, a
little to the east of Antares. These two southernmost constellations
never rise much above the horizon for France and England. In fable, the
Archer is Chiron, the preceptor of Jason, Achilles and Æsculapius.
Capricorn lies to the south of Altaïr, on the prolongation of a line
from the Lyre to the Eagle. It is hardly noticeable save for the stars
[alpha] and [beta] of third magnitude, which scintillate on its
forehead.
The Water-Carrier pours his streams toward the horizon. He is not rich
in stars, exhibiting only three of third magnitude that form a very
flattened triangle.
Lastly the Fishes, concluding sign of the Zodiac, are found to the
south of Andromeda and Pegasus. Save for [alpha], of third magnitude,
this constellation consists of small stars that are hardly visible.
These twelve zodiacal constellations will be recognized on examining the
chart (Figs. 10-11).
We must now visit the stars of the Southern Heavens, some of which are
equally deserving of admiration.

It should in the first place be noted that the signs of the Zodiac and
the Southern Constellations are not, like those which are circumpolar,
perpetually visible at all periods of the year. Their visibility depends
on the time of year and the hour of the night.[4]
In order to admire the fine constellations of the North, as described
above, we have only to open our windows on a clear summer's evening, or
walk round the garden in the mysterious light of these inaccessible
suns, while we look up at the immense fields in which each star is like
the head of a celestial spear.
But the summer is over, autumn is upon us, and then, too soon, comes
winter clothed in hoar-frost. The days are short and cold, dark and
dreary; but as a compensation the night is much longer, and adorns
herself with her most beautiful jewels, offering us the contemplation of
her inexhaustible treasures.

spring; Crab, Twins, Bull, Ram, Fishes, Water-Carrier.]
First, let us do homage to the magnificent Orion, most splendid of all
the constellations: he advances like a colossal giant, and confronts the
Bull.
