6h. 21m. P.M., and a transit ingress of its shadow at 

 Bh. 26ni. P.M. On the Gth a transit ingress of the shadow 

 of the second satellite at Sh. 2m. p.m. ; a transit egress of 

 the satellite itself at .'Jh. 10m. p.m. ; and a transit egress of 

 its shadow at 7h. 51m. p.m. On the 8th an occultation 

 disappearance of the first satellite at 8h. 9m. p.m. On the 

 Oth a transit ingress of the first satellite at 5h. 17m. p.m.; 

 of its shadow at Gh. 38m. p.m. ; a transit egress of the 

 satellite at 7h. 36m. p.m., and of its shadow at 8h. 55m. p.m. 

 This transit should be carefully watched, as the satellite 

 may possibly appear to be double. On the 10th an eclipse 

 -reappearance of the first satellite at 6h. 13m. 53s. p.m. 

 On the 11th an occultation disappearance of the second 

 satellite at 9h. 46m. p.m. On the 12tli a transit ingress of 

 the third satellite at 6h. 59m. p. si., and of the fourth 

 satellite at 7h. 20m. p.m. This will be a very interesting 

 phenomenon. On the 13th a transit ingress of the second 

 satellite at 4h. 57m. p.m. ; of its shadow at 7h. 39m. p.m. ; 

 and a transit egress of the satellite itself 11m. later. On 

 the 16th an eclipse reappearance of the third satellite at 

 5h. 36m. 44s. p.m. ; a transit ingress of the first satellite 

 at 7h. 14m. p.m. ; of its shadow at 8h. 34m. p.m. ; and a 

 transit egress of the satellite itself at 9h. 33m. p.m. On 

 the 17th an eclipse reappearance of the first satellite at 

 8h. 9m. 26s. p.m. On the 18th a transit egress of the 

 shadow of the first satellite at 5h. 20m. p.m. On the 20th 

 a transit ingress of the second satellite at 7h. 38m. p.m. On 

 the 21st an eclipse reappearance of the fourth satellite 

 at 6h. 41m. 48s. p.m. On the 22nd an eclipse reappear- 

 ance of the second satellite at 7h. 12m. 51s. On the 

 23rd an eclipse disappearance of the third satellite at 

 6h. 37m. 2s. p.m., and a transit ingress of the first satellite 

 at 9h. 13m. p.m. On the 24th an occultation disappear- 

 ance of the first satellite at 6h. 34m. p.m. On the 25th a 

 transit ingress of the shadow of the first satellite at 4h. 

 69m. P.M. ; a transit egress of the satellite itself at 6h. Im. 

 P.M. ; and of its shadow at 7h. 16m. p.m. On the 29th a 

 transit egress of the fourth satellite at 6h. 42m. p.m. On 

 the 30th an occultation disappearance of the third satellite 

 at 5h. 31m. p.m. On the 31st an egress of the shadow 

 of the second sateUite at 5h. Om. p.m., and an occulta- 

 tion disappearance of the first satellite at 8h. 83m. p.m. 

 During the month .Jupiter describes a direct path in 

 Aquarius, but without approaching any naked eye star 

 very closely. 



Neptune is excellently situated for observation, rising as 

 he does on the 1st at 3h. 38m. p.m., with a northern de- 

 clination of 19° 58', and an apparent diameter of 2-7". On 

 the 31st he rises at Ih. 50m. p.m., with a northern de- 

 clination of 19" 51'. During the month he describes a 

 short retrograde path to the north of s Tauri. A map 

 of the stars down to 10^ magnitude near his path 

 will be found m the Kmilish Mechanic for October 16th, 

 1891. 



December is a fairly favourable month for shooting 

 stars, the chief shower being that of the Geminids on 

 December 9th-12th, the radiant point being in II. A. 

 7h. Om., and north declination 32°, rising about 4h. 10m. 

 P.M., and setting at Ih. 40m. a.m. 



The Moon enters her first quarter at 5h. 13m. p.m. on 

 the 8th ; is full at Oh. 53m. a.m. on the 15th; enters her 

 last quarter at 5h. 38^m. on the 23rd ; and is new at 

 8h. 20m. A.M. on the 31st. She is in perigee at 6-lh. 

 p.m. on the 11th (distance from the earth, 228,540 miles) ; 

 and is in apogee at 6-Oh. p.m. on the 23rd (distance 

 from the earth, 241,300 miles). The greatest eastern 

 librations arc at Ih. 7m. p.m. on the 3rd, and at Ih. 30m. j 

 A.M. on the 30tii ; and the greatest western at 4h. 18m. p.m. I 

 on the 17th. j
