MARS.
Of this planet we have little to report. He continues his direct motion, which amounts to 9° 30′ 34″. As he and the earth are getting farther apart, his diameter (apparently) diminishes from 10″ to 8″. He rises on the 1st, 15th and 30th at 12:27 p. m., 11:54 a. m., and 11:24 a. m., and sets on the 2d, 16th, and May 1st at 3:09, 2:22, and 1:38 a. m., respectively. On the 4th, at 10:26 a. m., his position is 8° 10′ north of the moon, and on the 1st a little northeast of the nebula Præsepe in Cancer.
JUPITER
Continues to be evening star, coming to the meridian on the 1st, 15th and 30th, at 7:04, 6:13 and 5:20 p. m., and setting on the 2d, 16th, and May 1st at 2:24, 1:32 and 12:38 a. m. His motion, which is direct, amounts during the month to 4° 27′ 33″. His diameter diminishes from 37.8″ to 34.6″, an indication that our distance from him is increasing. On the 3d, at 1:52 p. m., he is 6° north of the moon; and on the 14th, at 7:00 p. m., 90° west of the sun.
SATURN
Continues his position not far from the bright star Aldebaran, in the constellation Taurus, on the 1st being about 2° 53′ west and 3° 32′ north, while on the 30th he will be about 30′ east and 4° 7½′ north of this star. His motion is direct and amounts to 3° 24′. Diameter diminishes from 16.2″ on the 1st to 15.8″ on the 30th. Setting at 10:47, 9:59 and 9:09 p. m. on the 1st, 15th and 30th he will be evening star throughout the month. On the 12th, at 11:00 p. m., is 4° 13′ south of Venus, and on the 27th, at 1:56 p. m., 2° 19′ north of the moon.
URANUS,
Formerly and still sometimes called Herschel, from the name of its discoverer, Dr. Herschel, has made but about one and one-fifth revolutions about the sun, since its discovery in 1781, more than a century ago. It is now near the star Beta Virginis, and making a retrograde motion of about 56′ 30″ in 30 days. Its diameter is 3.8″. It rises at 4:53 p. m., 3:55 p. m. and 2:54 p. m. on the 1st, 15th and 30th, and sets at 5:09 a. m., 4:13 a. m. and 3:13 a. m. on the 2d, 16th, and May 1st. On the 6th, at 6:27 a. m., it is 3° 27′ north of the moon. Is evening star during the month.
NEPTUNE
Is evening star, setting at 9:24, 8:32 and 7:28 p. m. on the 1st, 15th and 30th, respectively. Its motion, 1° 2′ 37″, is direct. Diameter, 2.6″. On the 21st, at 2:00 a. m., 4° 20′ south of Mercury, and on the same day will set about fifteen minutes later than said planet. On the 26th, at 8:27 a. m., 44′ north of moon.
