MONOCEROS (mō-nos'-e-ros)—THE UNICORN. (Face South.) LOCATION.-Monoceros is to be found east of Orion between Canis Major and Canis Minor. Three of its stars of the fourth magnitude form a straight line northeast and southwest, about 9 degrees east of Betelgeuze, and about the same distance south of Alhena, in Gemini. The region around the stars (8), (13), (17) is particularly rich when viewed with an opera-glass. The clusters (50 M) and (2) are well worth observing. ERIDANUS (ē-rid’-a-nus)—OR THE RIVER PO. (Face Southwest.) LOCATION. Three degrees north and two degrees west of Rigel, in Orion, lies (ß) Eridani, the source of the River. Thence it flows west till it reaches (7) Ceti, then drops south 5 degrees, thence east southeast, its total length being about 130 degrees. The great curve the river takes, just east of the Whale, resembles a horseshoe. Acherna, the first-magnitude star in Eridanus, is too far south to be seen in this latitude. Note the pretty star group around (ß) and a pair of stars of an orange hue below (v). The asterism known as "The Brandenburg Scepte consisting of four stars of the fourth and fifth magnitude, an be First seen standing in a straight line north and south below the bend in the River, just west of Lepus.
