It rises when the sun sets on August 24th, andculminates at 9 on November loth. Astrologicallyit portends honour and riches. Gamma, or Almaak, a star of nearly the secondmagnitude (2,3), is interesting as being one of the mostbeautiful triple stars in the heavens, producing a finecontrast of colours. It is of a topaz-yellow colour, andhas an emerald-green companion of the fifth magnitudewhich is in itself a double, having an eighth-magnitude. Yerkes Gb.^ Plate XV. The Great Nebula in Andromeda (Of the seventeen novas thus far known to have appeared in spiral nebulas,eleven have been found in this famous spiral. Then, too, the discovery ofnovs in spirals has led some astronomers to regard the latter as independentsystems or island universes. Moreover, recent spectroscopic observationslend support to the belief held by many, that the spiral nebula; are made upof great and infinitely distant clouds of stars, and that they have enormousspace velocities.) 1 The Night-Sky of Autumn 157 companion of a bluish colour. Its duplicity was dis-covered by Johann Mayer in 1788, while WilhelmStruve found its companion to be a close double in principal star is easily separated in an ordinarytelescope. The first and second companions form abinary with a period of about fifty-four years, butrequire a very powerful
