ECLIPSES OF THE SATELLITES OF JUPITER IN 1848. Visible in the United States, Mean Time at Washington Observatory.

A Table showing the Illuminated Portions of the Discs of Venus and Mars.

The numbers in this table are the versed sines of that portion of the Discs, which to an observer on the Earth, will appear to be illuminated, the apparent diameter of the planet at the time being considered as unity.

To a spectator on the Earth, Venus appears most brilliant when her elongation is about 45°, and she is approaching her inferior conjunction, or receding from it; in which positions she will not be this year. Mars is

most brilliant about the time of his opposition to the Sun, being then also nearest to the Earth, in which position he will not be this year.

Position and Magnitude of the Rings of Saturn, according to Bessel and Struve, for every fortieth day in the year, at 7 hours in the morning.
