On the 21st, a ninth magnitude star will be situated a few 

 seconds of arc north of the planet, actual conjunction with 

 the centre taking place at about 5h. p.m. On the 22nd, a 

 transit ingress of the first satellite at 6h. 56m. p.m., of its 

 shadow at 8h. 18m. p.m. ; a transit egress of the satellite 

 at 9h. 15m. p.m., and of its shadow at lOh. 35m. p.m. 

 On the 24th, an eclipse reappearance of the first satellite 

 at 7h. 53m. 43s. p.m. ; and an occultation disappearance 

 of the third satellite at 8h. 48m. p.m. On the 25th, a 

 transit egress of the shadow of the first satellite at oh. 4m. 

 P.M. ; and a transit ingress of the second satellite at 

 lOh. 22m. p.m. On the 2fjth, a transit egress of the shadow 

 of the fourth satellite at 6h. 18m. p.m. On the 27th, an 

 eclipse reappearance of the second satellite at lOli. Om. 45s. 

 p.m. On the 28th, a transit egress of the shadow of the 

 third satellite at 7h. 40m. p.m. On the 29th, a transit 

 egress of the shadow of the second satellite at 5h. 14m. 

 p.m. On the 30th, a transit ingress of the first satellite at 

 Hh. 52m. P.M., and of its shadow at lOh. 13m. p.m. .Jupiter 

 is stationary on the 3rd, and after that pursues a short 

 direct path in Aquarius, but without approaching any naked

Neptune is admirably situated for observation, coming 

 into opposition with the Sun on the last day of the month 

 at a distance from the earth of about 2680^ millions of 

 miles. He rises on the 1st at 5h. 53m. p.m., with a 

 northern declination of 20° 6' and an apparent diameter of 

 2-7". On the 3t)th he rises at 3h. 51m. p.m., with a 

 northern declination of 19° 59'. He describes a short re- 

 trograde path in Taurus, to the N.W. of s Tauri. A map 

 of the stars down to 10| magnitude near his path will be 

 found in the Kw/lisli Mechanic for October 16th, 1891. 



November is a very favourable month for shooting stars. 

 The most marked displays are the Lcaiiids on November 

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

 northern declination 23°. The radiant point rises at about 

 lOh. 15m. P.M. The Andromedes occur on the 27th, the 

 radiant point being in R.A. Ih. 40m., northern declina- 

 tion 4.3°. 



The Moon is new at 6h. 33m. p.m. on the 1st ; enters 

 her first quarter at 8h. 46m. a.m. on the 9th ; is full at 

 Oh. 16m. A.M. on the 16th ; and enters her last quarter at 

 8h. 26m. A.M. on the 23rd. She is in perigee at l-2h. 

 A.M. on the 14th (distance from the earth, 225,015 miles), 

 and in apogee at 8-8h. p.m. on the 25th (distance from 

 the earth, 251,690 miles). The greatest eastern libration 

 is at 3h. Om. a.m. on the 7th, and the greatest western 

 at 7h. 16m. p.m. on the 9th. There will be a very line 

 total eclipse of the Moon on the night of the 15th and 

 early morning of the 16th. The first contact with the 

 penumbra is at 9h. 37m. p.m. on the 15th ; with the shadow 

 (at 55° from the northernmost point of the Moon's limb 

 towards the east, direct image) at lOh. 35m. p.m. ; begin- 

 ning of total phase, llh. 37m. p.m. on the 15th ; middle of 

 the eclipse. Oh. 19m. a.m. on the 16th ; end of total phase, 

 Ih. Om. A.M. on the 16th ; last contact with the shadow 

 (at 95° from the northernmost point towards the west) at 

 2h. 3m. A.M. on the 16th ; last contact with the penumbra 

 at 3h. Im. a.m. on the 16th. The magnitude of the 

 eclipse (Moon's diameter — 1), 1-386.

T. — Your solution is counted correct, though it is barely 

 legible. Could you not rectify this in future ? 



C. T. lHunshiird.—'M&ny thanks ; but got your letter too 

 late to make use of ticket. 



G. F. — The Centre Counter Gambit is undoubtedly the 

 best defence when receiving the odds of QKt. 



C'. ,S'. — The revised position is a great improvement, but 

 there seems to be no mate after 1. . . B to Ksq. Should 

 be glad to insert when sound.

 equally good after 1 ... P to Kt3.

The attention of competitors is called to the following 

 amended rule : — " Should a problem admit of more than 

 one key-move, ticit additional points will be awarded for 

 each discovery of such key-move in the case of two-move 

 problems, and four additional points in the case of other 

 problems. The same number of marks will be deducted 

 should any such claim prove incorrect."
