P.M. 



Saturn is an evening star and is getting into a favourable 

 position for observation, though he does not rise to any 

 very great altitude above the horizon. On the 1st he rises 

 at 8h. 28m. p.m., or about two hours after sunset, with a 

 southern declination of 10" 51', and an apparent equatorial 

 diameter of 18|" (the major axis of the ring-system being 

 43^" in diameter, and the minor 13J"). On the 11th he 

 rises at 7h. 45m. p.m., or one hour after the Sun, with a 

 southern declination of 10" 36', and an apparent equatorial 

 diameter of 19" (the major axis of the ring-system being 

 43j" in diameter, and the minor 13"). On the 20th he 

 rises at 7h. 5m. p.m., or about sunset, with a southern 

 declination of 10" 23', and an apparent equatorial diameter 

 of 19" (the major axis of the ring-system being 43i-" in 

 diameter, and the minor 13"). On the 30th he rises at 

 6h. 23m. P.M., with a southern declination of 10° 7', and 

 an apparent equatorial drameter of 19" (the major axis of 

 the ring-system being 43 1" in diameter, and the minor 

 12|"). Titan is at his greatest eastern elongation at 6h. 

 P.M. on the 15th ; and lapetus at western elongation about 

 llh. A.M. on the 3rd, and in superior conjunction at 3h. 

 p. Jr. on the 23rd. During April, Saturn pursues a short 

 retrograde path in Virgo, without approaching any con- 

 spicuous star. 



Uranus is an evening star, and but for his great southern 

 declination would be well situated for observation. He rises 

 on the 1st at 9h. 54m. p.m., with a southern declination 

 of 17|°, and an apparent diameter of 3-8 '. On the 30th 

 he rises at 7h. 53m. p.m., with a southern declination of 

 16° 56'. During April he describes a short retrograde 

 path in Libra. 



Neptune is still an evening star, but must be looked for 

 as soon after sunset as possible. He sets on the 1st at 

 lOh. 10m. A.M., with a northern declination of 20° 59', 

 and an apparent diameter of 2-6". On the 30th he sets 

 at lOh. 20m. p.m., with a northern declination of 21° 6'. 

 During the month he describes a short direct path to the 

 south-west of t Tauri. A map of the small stars near his 



path will be found in the English Mechanic for September 

 7th, 1894. 



Shooting stars are fairly plentiful in April, the best- 

 marked shower being that of the Lyrids, with a radiant 

 point in E.A. 18h. + 38°. The radiant point rises on the 

 evenings of the 19th and 20th, when the maximum occurs, 

 at about 6h. 27m. p.m., and souths at 4h. 8m. a.m. 



The Moon enters her first quarter at Oh. 28m. p.m. on the 

 2nd ; is full at Ih. 43m. p.m. on the 0th ; enters her last 

 quarter at llh. 22m. p.m. on the 16th; and is new at 

 Ih. 11m. A.M. on the 25th. She is in perigee at 5h. a.m. 

 on the 7th (distance from the earth 226,220 miles), and 

 in apogee at Ih. a.m. on the 10th (distance from the earth 

 251,370 miles). 



Erratum. — In " Face of the Sky " for February and 

 Jlarch the equatorial semi-diameters of Saturn were 

 inadvertently given for the equatorial diameters.
