the month, reaching the point of superior conjunction 

 on the 19th. 



Venus is an evening star, and will reach her greatest 

 brilliancy on October 27th. Throughout the month she 

 sets about an hour after the Sun. On the 15th only one- 

 third of the disc will be illuminated, and as the apparent 

 diameter will then be 34-0'', very small telescopes will 

 sutBce to show the orescent phase. The apparent diameter 

 increases from 2S0" to 43-8" during the month. 



Mars is gradually coming into a more favourable 

 position for observation, but the approaching opposition is 

 by no means a good one for telescopic work. His apparent 

 movement during the next few months, however, will be 

 well worth the attention of young observers, and as a 

 companion to such observations we give a diagram 

 illustrating his path. He will rise shortly after ten on 



Conveniently observable minima of Algol will occur on 

 the 5th at 9. .18 p.m. ; on the 25th at 11.40 p.m. ; and on 

 the 28th at 8.29 p.m. 



Mira Ceti is near a maximum.

the 1st, and about half-past nine towards the end of the 

 month. The planet will be in quadrature on the 17th, 

 and 0'H8" of the disc will then be illuminated, while the 

 apparent diameter will be 8 0". As wiU be seen from the 

 diagram, his path is in Gemini during October. 



Jupiter is in conjunction with the Sun on the 13th, and 

 will not be observable. 



Saturn is still an evening star, but is getting too near 

 the Sun to be well observed. At the beginning of the 

 month he sets about two hours after the Sun, and at the 

 end about one and a half hours after. The apparent minor 

 axis of the ring is still greater than that of the planet, the 

 respective values at the middle of the month being 10" and 

 14-4", while the major axis of the ring is 36'. He may be 

 found about 6 ' north of Antares at the beginning of the 

 month, and afterwards a little to the east of that point. 



Uranus also remains an evening star, but is still nearer 

 the Sun than Saturn, and may be considered as not 

 observable. 



Neptune, in Taurus, rises about 9 p.m. at the beginning, 

 and about 7 p.m. at the end of the month, his apparent 

 diameter being 2.G". He is a little more than 1^° north- 

 east of ? Tauri. 



The Moon enters her last quarter on the 7th at 6.5 p.m. ; 

 is new on the 15th thirty- seven minutes after noon; enters 

 the first quarter on the 22nd at 9.9 a.m. ; and is full on 

 the 29th eighteen minutes after noon. On the 19th she 

 will occult the star B.A.C. 5878, Mag. 6|. The disappear- 

 ance wLU take place at 4.50 p.m., 73^ from the vertex, and 

 the reappearance at 6.1 p.m., 289' from the vertex, the 

 Moon's age being 4d. 4h., and the time of sunset 4.57 p.m. 

 On the 22nd, p Capricomi, Mag. 5, will be occulted ; 

 disappearance at 5.5 p.m., 28° from the vertex, and re- 

 appearance at 5.51 P.M., 303° from the vertex. The Moon's 

 age will be 7 days, and the time of sunset 4.50 p.m.

Correct Solutions of both problems received from 

 Alpha, J. T. Blakemore, H. S. Brandreth, H. Le Jeune. 



Of No. 2 only, from G. G. Beazley, J. M'Robert, W. de 

 P. Crousaz, W. Clugston. 



Mr. J. Nield, the composer of the August problems, 

 points out that No. 2 is rendered sound by the addition of 

 a Black Pawn at K7.
