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 diameters of the planets 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. The inferior conjunction will not take place this year. Mars is most brilliant about the time of his opposition to the Sun, being then also nearest the Earth; in which position he will be in March and April, 1856.
