_By an accident, the remarks relating to_ SPRING _were inserted under_ MARCH 6, _instead of this day_: and as the error is thus _particularly_ noticed, in order as far as possible to rectify it, the reader will please to consider all that has been said on the _sixth_ of March as applicable to the _twentieth_ alone. The editor, while acknowledging, and craving pardon for a vexatious and unpurposed misrepresentation, will endeavour to set a watch upon himself in future, to guard against a similar accident. Aries, or the ram, as a zodiacal sign, is said to have been derived by the Greeks from the golden fleece brought from Colchis by Jason, about 1263 years before Christ; but as it is a hieroglyphic on Egyptian monuments, it is of higher antiquity, and symbolizes that season when sheep yean their lambs. The people of Thebes slew a ram in honour of Jupiter Ammon, who personifies the sun in Aries, and is represented by ancient sculpture and coins with the horns of a ram on his head. The Hebrews at this season sacrifice a lamb, to commemorate their deliverance from Egypt. Aries, or the ram, was the ensign of Gad, one of their leaders. [Illustration: ~Aries.~] VERNAL EQUINOX. The remarks on the _Vernal Equinox_, immediately following, are communicated by a respected scientific friend to the editor. This is a day of great consequence in the year, and one that must excite many associations in the mind of the astronomer, and of every one who entertains a due reverence for our sacred records. The sun on this day passes the imaginary line in the heavens, called the equator, or equinoctial; it being the middle circle equally distant in every part from the north or the south poles. The line is passed to an observer on Greenwich hill, at ten minutes past nine in the morning; and, consequently, when it is on the meridian, or its highest point at noon, it will appear to every observer in the united kingdom at some distance from the equator. It is commonly said, that at this time the day is equal to the night all the world over; but this is a vulgar error. The day is not equal to the night in this country; that is, the sun appears for more than twelve hours above the horizon, and, consequently, a less time than twelve hours elapses before it shines again to us in the morning. Besides, the fallacy of this common saying is perceived at once by any one who considers, that the inhabitant of the north pole, if there is any inhabitant there, has already seen for some days the sun above his horizon, and it will not set to him for above six months. The day then is not equal to the night, either in the united kingdom, or at the north pole. We will leave to the astronomer to determine at what part of the earth this circumstance really takes place; in the investigation of the problem he may encounter some difficulties, of which at present he is probably not aware. The sun crosses the equinoctial line at ten minutes past nine; it was therefore at its
