** The Angles are reckoned towards the right hand round the circumference of the Moon's image as seen in an inverting telescope. For direct image, take the opposite points; that is, in numbers, add or subtract 180°. The Angles from North Point and Vertex" will also indicate the position of the meridian; thus, if the larger angle be that in the left-hand column, the objects will be situated on the left of the meridian; and vice versa. The "Sidereal Times" are given for the use of those having observatories and astronomical Sidereal clocks. General readers will take the times of "disappearance" and "reappearance" from the columns headed "Mean Time," and they will bear in mind that they are always counted from noon. When the time stated is less than 12h it therefore denotes the time in the afternoon: when it exceeds the 12h, by rejecting the 12h the remainder will indicate the time on the following morning; and, in each case, according to Greenwich mean time, which is now uniformly exhibited by railway and public clocks in the United Kingdom.

visible to the whole of Europe, Africa,
and South America, the more western
parts of Asia, and on the Atlantic and
Southern Oceans.
September 7. SUN partially eclipsed,
invisible. Begins on the earth generally
at 11h 100m A.M., mean time at Green-
wich; ends on the earth generally at
2h 27-0m P.M. Greatest eclipse. Mag-
nitude 0.639 (sun's diameter = 1) at
Oh 48.5m P.M., in longitude 91° 48' W.,
and latitude 61° 22 S. The eclipse
will be chiefly visible to the southern
parts of South America and on the
Southern Ocean.

VENUS will be a morning star until May 7, the time of her superior conjunction with the Sun; and she will be an evening star after that date.

MARS will be in opposition to the Sun on September 5.

JUPITER will be in opposition to the Sun on June 19.

SATURN will be in opposition to the Sun on September 9. The splendid rings of the planet, from change of position with respect to the earth, are almost closed, and they will eventually disappear for a time in the course of the year 1878, after which the opposite sides will become visible.

NOTE.-In Great Britain, at all places, Greenwich or Railway time is used in common, so that the eclipses of the Moon will not require any correction for longitude.

IN THE SEVERAL COUNTIES OF ENGLAND AND WALES.

By the Act 1 Will. IV. c. 70, it is enacted that "in the year 1831, and afterwards, the Justices of the Peace in every county, riding, or division, for which Quarter Sessions of the Peace by law ought to be held, shall hold their general Quarter Sessions of the Peace in the first whole week after the 11th October, in the first week after the 28th of December, in the first week after the 31st of March, and in the first week after the 24th of June." The following list has been computed according to this rule.

The Act 4 and 5 Will. IV. cap. 47, allows a discretionary power to the Justices of Peace as to the time of holding the Spring Quarter Sessions, and empowers them to alter the day for holding the Sessions, so as not to be earlier than the 7th of March, nor later than the 22nd of April. The dates given below are, therefore, only provisionally fixed, and may be altered.
