 Minima of Algol may l)e observed on the 10th at 

 1.21 A.M., 12th at 1(1.9 P.M., and on the 1.5th at 6.58 p.m. 



Telescopic Objkcts. — Nebulae. — Orion Nebula, situ- 

 ated in the sword of Orion, and surrounding the niulti[>le 

 stiir $, is the finest of all nebulsB, and is so bright that it 

 can lie discerned with the naked eye ; with a 'S or 4-iuch 

 telescope, it is best observed when low powers are em- 

 ployed. 



Crab Nebula (M 1), in Taurus, situated about lj° 

 north-west of K Tauri in R.A. 5h. 29m., Dec. 21° 58' N. 



Clusters. — il 37, situated in Auriga, is one of the finest 

 clusters, and verv compact ; its position is R.A. 5h. 46m., 

 Dec. 32^ 32' N. " 



Double Stars. — j3 Orionis (Rigelj, mags. 1 and 9, 

 separation 9". On account of the brightness of the prin- 

 cipal star, this double is a fair test for a good object- 

 glass of about 3.inch aperture. 



S Orionis, mags. 2 and 7, se]iaration 53" ; easy double. 



K Orionis, triple, mags. 3, 6, and 10, separation 2"5 and 

 50" ; rather difficult in a 3-inch telescope. 



A Orionis, mags. 4 and 6, sepai-ation 4"'5 ; pretty 

 double. 



o" Orionis, triple, mags. 4, 8 and 7, separation 12"'5 and 

 42". There are several other small stars near, and the 



Diagram of c Orionis. 



detection of the fainter ones is looked upon as a good test 

 of the light-gathering power of the telescope. With a 

 3-inch, one can see up to number 7, though 4 is very 

 difficult.

Result op Solution Tourney, 1903. 



Winner of the Knowledge Challenge Trophy. — C. 

 Johnston, 83. 



Winner of Second Prize (15s.). — ^" Looker-ou " (G. J. 

 Slater, Bolton), 82. 



Winner of Third Prize (Knowledge for 12 months). 

 —J. W. Dixon, 81. 



These are closely followed by W. Nash and " Quidam," 

 80. Other scores worthy of mention being : G. W. 

 Middleton, 73; "Alpha," 68; H. F. Cuhuer, 64; G. A. 

 Forde (Major), 62 ; and T. Dale, 58. Mr, Dale did not 

 compete iluring tlio first three months, or he would 

 evidently have taken a much higher place. 



The above award will remain open for one month. 



The sct)res of the first five show the closeness of the 

 competition, the ri'sult of which was in doubt till tlie last. 

 Last year Mr. " W. Jay " came out with a clear lead of 

 four points. In the present competition the liolder of the 

 trophy retired early, and Mr. C. Johnston, who tied for 

 fourth place last year — 20 points behind Mr. .lay — scores 

 a well-<ieserved success and becomes the second holder of 

 the Challenge Trophy, "Looker-on" (Mr. G. J. Slater, the 

 well-known composerj once more taking the .second place. 

 Mr. Di.xon, winner of the third prize, did not compete last 

 year. The same applies to " Quidam " ; Mr. W. Nash is 

 a place lower.
