Abstract
MERCURY AS A MORNING STAR.—Although the present elongation of Mercury—the planet was at greatest western, elongation (20° 20′) at 2h. on Sunday last—is not so favourable for the naked-eye observation of the planet as, those which took place in February and August respectively, tffere is a possibility that during the next day or two observers may be able to pick up this elusive object near the eastern horizon just before dawn. Oil December 6. the planet will rise at 5h. 57m. a.m., the sun at 7h. 51m., whilst on December 8 the respective times will be 6h. 4m. and 7h. 54m.
