26th an ocoultation disappearance of the first satellite at 

 3h. 55m. A.M., and its eclipse reappearance at 6b. 13m. 57s. 

 A.M.; a transit ingress of the second satellite at 5h. 49m. p.m.,

 satellite itself at 8h. 25m. p.m., and a transit egress of the 

 shadow of the satellite at 8h. 37m. p.m. At Gh. p.m. the 

 of magnitude star 3 Geminorum will be 1^' / and 6-0'

 10b. 21m. p.m. ; a transit ingress of the third satellite 

 at lOh. 41m. p.m. ; a transit ingress of its shadow at 

 lib. 11m. p.-M. At 8 p.m. a lOtb magnitude star will be 

 J' south of the limb. On the 28th an eclipse reappearance 

 of the first satellite at Oh. 42m. 43s. a.m. ; a transit

Saturn and Uranus are, for the observer's pm-poses, 

 invisible. 



Neptune is an evening star, and is excellently situated 

 for observation, being in opposition to the Sun on the 6th, 

 at a distance from the earth of about 268 1-|^ millions of 

 miles. He rises on the 1st at 4b. 15m. p.m., with a 

 northern declination of 21^ 2', and an apparent diameter 

 of 2-7". On the 31st he rises at 2b. 10m. p.m., with a 

 northern declination of 20° 57'. A map of the small stars 

 near his path will be found in the Emilkh Mechanic for 

 September 7th, 1894. He describes a retrograde path to 

 the S.W. of I Tauri. 



December is a fairly favourable month for shooting 

 stars, the chief showers being those of the Gemiuids on 

 December 9tb to 12th, the radiant point being in 

 fl.A. 7h. Om., and north declination 32°, rising about 

 4h. 10b. P.M., and setting at lb. 40m. a.m. ; and of the 

 Andromedas, occurring on the evenings of the 26tb and 

 27th, the radiant point being in E.A. Ih. 40m., and 

 north declination 43°, the shower being circumpolar.

 5th ; is fuU at 7h. 46m. p.m. on the 12tb ; enters her last 

 quarter at lib. 16m. a.m. on the 19tb ; and is new at 

 2b. 20m. A.M. on the 27th. She is in apogee at 7h. p.m.
