Saturn is an evening star, rising on the 1st at lOh. 10m. 

 P.M., with a soTitheru decHnation of 2° 40', and an apparent 

 equatorial diameter of 17'1" (the major axis of the ring 

 system being 41 w" in diameter, and the minor 6^"). On 

 the 28th he rises at 8h. 16m. p.m., with a northern 

 declination of 2° 8', and an apparent equatorial diameter 

 of 17'9 ' (the major axis of the ring system being 48" in 

 diameter, and the minor 6i"). Titan is at his greatest 

 eastern elongation at 2-3h. p.m. on the 6th, and at 0-7h. 

 P.M. on the 22nd. lapetus is at superior conjunction at 

 l-.5b. A.M. on the 14th. The accompanying map* (based 

 upon Cottam's smaller star charts, with a few minor 

 alterations) shows the path of the planet in the con- 

 stellation Yirgo (and the principal stars and nebulre near) 

 from February 1st to September 1st, the position of the 

 planet on the first day of each month being marked with 

 a cross. The magnitude of the principal stars are : 

 y Virginis (binary), 3-1 ; S Virginis, 3-5 ; ij Virginis, 4-0; 

 10 Virginis, 5-5 ; 13, 143 P. xii., 38, 44, and 46 Virginis, 

 6-0. All the other stars are below the 6th magnitude. 

 The numbers attached to the nebube are fi-om Dreyer's 

 new General Catalogue. On the evening of the 3rd a 9-3 

 magnitude star will be occulted by the planet, the central 

 occultation taking place at about 8h. .50m. p.m. On the 

 evening of the 23rd the planet will be about |° north of 

 38 Virginis. 



As Uranus does not rise till after llh. p.m. on the last 

 day of the month, we defer an ephemeris of him till March. 



Neptune is still well situated for observation. He rise= on 

 the 1st at llh. 44m. a.m., with a northern declination of 

 20° 12', and an apparent diameter of 2-6'. On the 28th 

 he rises at 9h. 58m. a..m., with a northern declination of 

 20° 13'. He is almost stationary in Taurus, to the W.N.W. 

 of the 5| magnitude star, Weisse's Bessel-, iv. 650. A 

 map of the small stars near his path will be found in the 

 EnriUs/i Merhanir for October 28th, 1892. 



■rhere are no well-marked showers of shooting stars in 

 February. The zodiacal light should be looked for in the 

 west shortly after sunset on the nights from the 3rd to the 

 21st, v.'hen the Moon will not interfere with observation. 



The Moon is full at 2h. 11m. a.m. on the 1st ; enters 

 her last quarter at 8h. 12m. p.m. on the Sth ; is new at 

 4h. 17m. p.m. on the 16th ; and enters her first quarter at 

 2h. 14m. P.M. ou the 23rd. She is in apogee at 4h. a.m. 

 on the 9th (distance from the earth 251,230 miles), and in 

 perigee at 8h. p.m. on the 21st (distance from the earth 

 229,710 miles).

[Mr. S. Loyd, one of the judges, describes the above as 

 "a remarkably difficult, original and well-constructed 

 position, commencing with an excellent key, followed by 

 fine strategy." The other judges were even more 

 enthusiastic]
