before sunrise, and these should be fully utilized. The 

 radiant point of the shower, being near y Andromeda?, is 

 visible during the whole night. Prof. Abelmann has 

 recently pointed out, as Schulhof had previously done, that 

 a great disturbance of this system will be felt in 1901-2 

 by a near approach to Jupiter. The node will bo decreased 

 6'2 degrees, so that a shower will, for some years there- 

 after, occur on November 17th. In 1904 or 1905 it may 

 be possible to witness the Leonids and Andromedes in 

 simultaneous play. This will provide an interesting event 

 and allow comparisons to be made between the swift streak- 

 leaving meteors and the slow-trained meteors, for the 

 visible aspect of the objects forming the two systems are as 

 widely dissimilar as they can well be. Every meteoric 

 observer will, we are assured, be on the alert on November 

 15th and :i3rd-21th nest, in order to gather as many 

 facts as possible of the phenomena that will be displayed. 

 I am inclined to believe that the Leonids will be best seen 

 soon after midnight on the night following the 11th, while 

 the Andromedes will be most numerous just before sunrise 

 on the 24th, or in the early evening of that date. 



THE FACE OF THE SKY FOR NOVEMBER. 



By A. FoiS'LER, F.R.A.S. 



RECENT experience seems to indicate that the Sun 

 will be well worth careful observation for spots 

 and faculiB, and, in the event of a large spot 

 making its appearance, aurorte may be looked for 

 about the time of its passage across the central 

 meridian. 



Mercury is an evening star throughout the month, but 

 he is too far south for easy observation in our latitudes. 

 He will be at greatest eastern elongation (21°) on December 

 3rd. On November 20th, at 8 a.m., he will be in conjunction 

 with Venus, Mercury being 1^ 18' to the north. 



Venus is an evening star, but, on account of her great 

 southerly declination, is badly placed for observation after 

 sunset. She will be stationary on the 11th at 10 a.m., and 

 will afterwards rapidly approach inferior conjunction, which 

 is due on December 1st at 5 p.m. At the beginning of the 

 month she sets about a hour later than the Sun. 



Mars rises late in the evening in the north-east, and, 

 as will be seen from the diagram given last month, he 

 traverses an eastward path through Cancer. During the 

 month his apparent diameter increases from 8-8'' to 11-2", 

 and his horizontal parallax from 8-4 ' to 10-5". On the 

 8th his distance from us will be the same as that of the 

 sun. At the middle of the month 0-9' of his disc will be 

 illuminated. He will rise about half-past nine on the 1st, 

 and about eight o'clock at the end of the month. 



Jupiter is a morning star, but he is not sufficiently 

 removed from the Sun to permit observations of his satellites 

 before the 12th. At the middle of the month he rises 

 about two and a half hours before the Sun, his apparent 

 diameter being only 28'8". 



Saturn remains an evening star during the month, but 

 the time of conjunction with the Sun is so near that he 

 can scarcely be regarded as observable to those who have 

 not a perfectly clear horizon to the south-west. At the 

 middle of the month he sets about an hour after the Sun. 



Uranus is an evening star until the 25th, when he 

 arrives at the point of conjunction with the Sun. He may 

 be considered as not observable. 



Neptune rises shortly before 7 p.m. at the beginning of 

 the month, and about 5 p.m. towards the end. He is a 

 little more than li° north-east of ? Tauri. 



The Moon will enter her last quarter on the 6th at 



2.28 P.M.; will be new on the 14th twenty-one minutes 

 after midnight ; will enter her first quarter on the 20th at 

 5.5 P.M. ; and will be full on the 28th at 5.32 a.m. The 

 most interesting occultation during the month will be that 

 of 19 Piscium, Mag. 5-2, which will take place at a con- 

 venient time on the 22nd. The disappearance will occur 

 at 7.9 P.M., at a point 25° east of the north point (30° from 

 vertex) ; and the reappearance at 8.13 p.m., at 268° east of 

 the north point (2G0° from vertex). 



Conveniently observable minima of Algol will occur on 

 the 17th at 10.12 p.m. ; and on the 20th at 7 p.m. 



Mira Ceti will probably remain a naked eye star 

 throughout the month. 



Attention may be called to the recent development of 

 the central condensation of the Great Nebula in Andro- 

 meda, which is now well situated for observation. This is 

 not a reappearance of the " new " star of 1885, but is pro- 

 bably a temporarily increased brightness of the central 

 point of the nebula, which is known to be variable.

[The above pair have evidently proved very difficult. 

 One of the most expert of our solvers at first pronounced 

 the two-mover beyond him.]

H. S. Brandreth.— 1. P to B7 is met by K to B5. 



G. F. r.— After 1. Kt to Kt6ch, K to K3 ; 2. Kt to 

 Kt5ch is not mate.

A. C. Chalhnger. — Congratulations on your double
