urable, we shall be afforded an opportunity of witnessing another of
those interesting phenomena--eclipses, at least the latter part of one,
a portion of it only being visible to the inhabitants of this island;
the defect above alluded to is a lunar one. The passage of the moon
through the earth's shadow commences at 3 h. 29 m. 34 s. afternoon; she
rises at Greenwich at 4 h. 45 m. 34 s. with the northern part of her disk
darkened to the extent of nearly 10 digits. The greatest obscuration
will take place at 5 h. 7 m. 42 s. when 10-1/2 digits will be eclipsed; she
then recedes from the earth's shadow, when the sun's light will first be
perceived extending itself on her lower limb towards the east; it will
gradually increase till she entirely emerges from her veil of darkness,
the extreme verge of which leaves her at her upper limb 32 deg. from her
vertex, or highest point of her disc.

We have the following in "Moore," some years ago, on the nature and
causes of eclipses of the sun and moon:--

"Far different sun's and moon's eclipses are,
The moon's are often, but the sun's more rare
The moon's do much deface her beauty bright;
Sol's do not his, but hide from us his sight:
It is the earth the moon's defect procures,
'Tis the moon's shadow that the sun obscures.
Eastward, moon's front beginneth first to lack,
Westward, sun's brows begin their mourning black:
Moon's eclipses come when she most glorious shines,
Sun's in moon's wane, when beauty most declines;
Moon's general, towards heaven and earth together,
Sun's but to earth, nor to all places neither."

The Sun enters _Sagittarius_ on the 23rd, at 1 h. 2 m. morning.

Mercury will be visible on the 10th, in 10 deg. of _Sagittarius_, a
little after sunset, being then at his greatest eastern elongation; he
is stationary on the 20th, and passes his inferior conjunction on the
30th, at 1-3/4 h. afternoon.

Venus is in conjunction with the above planet on the 24th, at 9 h.
evening; she sets on the 1st at 5 h. 7 m., and on the 30th at 4 h. 47 m.
evening.

Jupiter may be seen before sunrise making his appearance above the
horizon about 5 h.; he is not yet distant enough from the sun to render
the eclipses of his satellites visible to us.

A small comet has just been discovered, situated in one of the feet of
_Cassiopea_. It is invisible to the naked eye, and appears
approaching the pole with great rapidity.
