on the 1st at 9h. r>Om. p.m., or 2h. 4m. after sunset, with a 

 southern dechnation of 1° 10', and an apparent equatorial 

 diameter of 1(3" (the major axis of the ring system being 

 37j" in diameter, and the minor 4-7"). On the Slst he 

 sets at 7li. nOm. p.m., or Ih. Hm. after sunset, with a 

 southern dechnation of 2*^ 22', and an apparent equatorial 

 diameter of 15]" (the major axis of the ring system being 

 36" in diameter, and the minor 5"). lapetus is at his 

 greatest eastern elongation on the 11th, and in inferior 

 conjunction on the 80th. A map of the path of Saturn 

 durmg August will be found in the "Face of the Sky" 

 for March. He is in conjunction with the beautiful pair 

 y Virginis shortly after lOh. a.m. on the 7th, the planet 

 being 31' south of the star. 



The above remarks as to the visibility of Saturn apply 

 also to Uranus. He sets on the 1st at lOh. 30m. p.m., 

 with a southern declination of 13° 23', and an apparent 

 diameter of 3-6". On the 31st he sets at 8h. 33m. p.m., 

 with a southern declination of 13° 40'. A map of his path 

 during August will be found in the " Face of the Sky " for 

 April. 



This month is one of the most favourable ones for 

 the observation of shooting stars. The most noted shower is 

 that of the Perseids with a radiant point at the maximum 

 display on August lOth in R.A., 2h. 52m., dec. + 56°. 

 Observation of this region of the heavens with an opera 

 glass will no doubt show stationary meteors, or meteors 

 which shift their positions very slowly. Their place, and 

 the direction of their shift, should be noted for the purpose 

 of determining whether the radiant is a geometrical point, 

 or a circle, or an elliptic area, as suggested with regard to 

 tlie November meteors. (Montldij Xotii-es of t/ic R.A.S., 

 Vol. xlvii., pp. 60-73.) The radiant point soutlis oa the 

 10th at 5h. 37m. a.m. 



The Moon enters her last quarter at 4h. 23m. p.m. on 

 the 5th ; is new at 8b. 48m. p.m. on the 11th ; enters her 

 first quarter at 9h. 52m. a.m. on the 19th, and is full at 

 8h. 43m. A.M. on the 27th. She is in perigee at Oh. p.m. 

 on the 8th (distance from the earth 227,130 miles), and 

 in apogee at 7h. p.m. on the 20th (distance from the earth 

 251,150 miles).

Solution of Jiih/ Problem (G. K. Ansell) : — 



Key-move, 1. R to B5. 

 If 1. . . . KxR, 2. P to Klch. 

 -If 1. . . . PxR, 2, BxPch. 

 If 1. . . . Anything else, 2. RxPch. 



Correct Solutions received from R. B. Cooke, Alpha. 



The defence to 1. Kt (Q5) to Kt6 (or B3, or K3), in Mr. 

 Loyd's problem in the June number, is 1. ... P to Kt8, 

 becoming a Bishop. If then 2. ... B to Q5 lUack is 

 stale-mated. R. I. has taken the hint and discovered this. 



In Mr. Donisthorpe's problem the Bishop must work 

 his way to KKt7, but he must capture the Black Pawn 

 I'll mute should Black play 1. ... B to R8, for otherwise 

 Black will secure a stale-mate by 2. ... P to Kt7. The 

 only key, therefore, is 1. B to K5. 



'This problem is correctly solved by R. I. and Alpha. 



ir. ,/„mr,s.— If 1. Kt (B8) to K7, Black defends himself 

 by checking with the Rook, either at once or on the second 

 move. 



Alpha. — The mysterious defence is given above. Many 

 thanks for the position appended. 



PROBLEM. 



By A. G. Fellows. 

 Black. 



White. 



White to play and mate in three moves. 



The following position from a Sanscrit work (translated 

 in 1818) is contributed by " Alpha." The solution is more 

 showy than difficult ; — 



White.— Is. at KB8, Q at QR2, R at KKt7, Kt at KB6, 



P at KKt5. 

 Black. — K at KRsq, B at QKt8. White to play and 

 mate with the Pawn in four moves. 



The late Mr. Ro3eaba,um once camposed a somewhat neater 

 and certainly more difficult i^roblem, with precisely the 

 same conditions : — 



Whit,-.—li at KR6, R at K7, Kt at QB7, P at K4. 



JUiwk. — E at KBsq. White mates with the Pawn in 

 four moves. 



The following game was played on the Atlantic last 

 month, the players being A. Walbrodt, on his way to 

 Berlin, and Max Judd, the recently appointed U.S. Consul 

 at Vienna. The score is from the lllustnitcd London 

 Neir-s : —
