ROUGH ASTRONOMICAL NOTES FOR THE USE OP STAR GAZERS. 1. Mercury will be fairly placed for observation on and about the 27th of the month. It will set nearly two hours after the Sun, somewhat south of his track. Its eastern elongation will be nearly 25|deg. 2. Venus will be well seen towards the end of the month. On the 27th it will set about twenty-five minutes after Mercury, and almost exactly in the same place. N.B.—As the northern declination (or distance north of the celestial equator) of these planets is now very considerable, and as they consequently appear to be only a small distance above the north-west horizon, those of our readers who have not a good horizon in that direction must not be surprised if they fail to aee the planets. 3. Mars is unfavorably situated. 4. Jupiter is still a very bright object, next to the Moon the brightest In the sky. 5. Saturn may be well seen during the whole of this mouth. About the Ist of June at 11 o’clock, it may be seen in the east, some distance above the horizon. It may be known at once by its peculiar golden yellow light. It is about as bright as an ordinary first magnitude star. .6. Uranus and Neptune are not favorably situated. 7. The only new first magnitude stars this month are Altair in the constellation of the JSagle, and Eomalhaut in the Southern Fish. Xncse two stars rise soon after Saturn, and are a long distance from it; Altair, a pale greenish to tlie norfc b, and Fomalhaut, a dead white star, to the south.
