 planet: — Superior, October 5tli, 6h. 18,jm. p.m., October 

 22nd, 9h. 23m. a.m. ; Inferior, October 14th, 3h. 18m. a.m.,

Saturn is in conjunction with the Sun on the 8th, and 

 Uranus is invisible. 



Neptune is well situated for observation, rising on the 

 1st at 8h. 8m. p.m., with a northern declination of 20° 54', 

 and an apparent diameter of 2-0". On the 31st he rises 

 at 6h. 6m. p.m.. with a northern declination of 20^ 50'. 

 During the month ho describes a short retrograde path 

 in Taurus, in a region barren of conspicuous stars. 



October is a fairly favourable month for shooting stars, 

 the most marl?ed display being that of the Orionids on the 

 18th, the radiant point being in vi.h. 8m. E.A., and 15"^ 

 northern declination. 



The Moon enters her last quarter at 3h. 19m. p.m. on 

 the 2nd ; is new at 8h. 27m. p.m. on the 9th ; enters her 

 first quarter at llh. 20m. p.m. on the 17th ; is fuU at 

 7h. 28m. A.M. on the 25th ; and enters her last quarter at 

 lOh. 42m. P.M. on the 31st. She is in apogee at lOh. a.m. 

 on the 15th (distance from the earth 251,626 miles) ; and 

 in perigee at 7h. a.m. on the 27th (distance fi'om the earth 

 225,040 miles).

Additional Solutions of August Problem received from 

 Alpha and H. S. Brandreth. 



Alpha.— Yoiiv original letter containing the above must 

 have miscarried. 



Poppy. — The Problem (" Sweetness, &c.") arrived safely. 



W. A. Chcaniiion. — The move 1. E to B3 in the Sep- 

 tember Problem is what is technically known as a good 

 " try." As you rightly observe, there is no mate if Black 

 replies 1. . . . Kt to K2. E to B3 cannot, therefore, be 

 the correct key ; you will find the latter given above.
