Both Saturn and Uranus are, for the observer's purposes, 

 invisible. 



Neptune is an evening star, and is very well situated for 

 observation. On the 1st he rises at 6h. 10m. p.m., with a 

 northern declination of 21= 8', and an apparent diameter of 

 2-7". On the 30th he rises at 4h. 17m. p.m., with a northern 

 declination of 21= 2'. During November he pursues a 

 retrograde path in Taurus, from the south to the south- 

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

 will be found in the Emjlish Mechmiic for September 7th, 

 1894. At the beginning of the month he is only about 

 20' south of L Tauri. 



November is a very favourable month for shooting stars. 

 The most marked displays are the Leonids on November 

 13th and 14th, the radiant point being in E.A. lOh. Om., 

 and northern declination 23°. The radiant point rises at 

 about lOh. 15m. a.m., but the :\Ioon will be full at the 

 time. The Andromedas occur on the 27th, the radiant point 

 being in R.A. Ih. 40m., and northern declination 43°. 



The Moon enters her first quarter at 3h. 16m. p.m. on the 

 5th ; is fuU at 7h. 49m. a.m. on the 13th ; enters her last 

 quarter at 2h. Sm. a.m. on the 20th ; and is new at 

 8h. 54m. A.M. on the 27th. She is in apogee at lOh. p.m. 

 on the 4th (distance from the earth 251,820 mOes), and 

 in perigee at 8h. p.m. on the 16th (distance from the 

 earth 228,190 mUes). At 4h. 29m. p.m. on the 7th (8m. 

 after sunset) the 6»- magnitude star 70 Aquarii wUl dis- 



appear at an angle of 42°, and reappear at 5h. 42m. p.m. 

 at an angle of 254^". On the evening of the 13th the full 

 Moon will pass through the Pleiades. At 7h. 38m. p.m. 

 the 4^ magnitude star 23 Tauri (Merope) will make a near 

 approach (8' distance) to the northern limb at an angle 

 of 336° ; at 8h. 9m. p.m. the 3rd magnitude star r^ Tauri 

 (Alcyone) will make a near approach (5' distance) to the 

 northern limb at an angle of 336° ; at 8h. 29m. p.m. the 3J 

 magnitude star 27 Tauri (Atlas) will disappear at an angle 

 of 21°, and reappear at 9h. 14m. p.m. at an angle of 290°; 

 at 8h. 50m. p.m. the 5i magnitude star 28 Tauri (Pleione) 

 will disappear at an angle of 347°, and reappear 13m. 

 later at an angle of 324°. At 7h. 9m. p.m. on the 15th 

 the 4| magnitude star 136 Tauri wUl disappear at an 

 angle of 119=, and reappear at 7h. 50m. p.m. at an angle 

 of 224°. At Oh. 3m. a.m. on the 17th the 5i magnitude 

 star 47 Geminorum will disappear at an angle of 162=, and 

 reappear at Ih. 6m. a.m. at an angle of 249°. At 2h. Om. 

 a.m. on the 20th the 6\ magnitude star 84 Leonis wUI dis- 

 appear at an angle of 159°, and reappear at 2h. 40m. a.m. 

 at an angle of 251°. At 5h. 57m. a.m. on the 23rd the 

 5| magnitude star B.A.C. 4531 wiU make a near approach 

 at an angle of 214°.

CoRBECT SoLiTiox received from W. Willby. 



,/. J. A. — Your solution to No. 1 arrived too late to 

 acknowledge last month. The other solution was in- 

 correct. 



J. E. Gore. — Thanks for the problems. In No. 1 the 

 key is too obvious, the piece moved being obviously useless 

 where it stands. Could you not find a better key ? The 

 Pawn at Kt5 seems unnecessary. No. 2 is clearly solved 

 in one move by 1. Kt to B5ch. There is no solution in 

 two moves, on account of the check of the Black Rook. 

 Of course a second key is a fatal defect. The problem 

 referred to was inserted without due examination. 



A. C. Challewjer. — The problems received are good as 

 usual. We shaU be glad to pubUsh them shortly. 



A. G. Fellows. — Many thanks for the two problems, 

 which wUl probably appear in the next number but one. 

 It is to be feared, however, that most of our solvers will 

 I think them too diflicult to attempt.
