A most delicate double star, in the Unicorn's eye. A 6, yellowish white; B16, dusky. This is indeed a difficult object, B being the minimum visibile of my instrument, and with it only seen by such transient glimpses, that but for a distant pale lOth-magnitude star in the sp quadrant, nearly in the same line of bearing, my estimations must have been much wider. There is also a dusky 12th star in the sf, at about 100" from A; so that the whole forms a wide quadruple object. It is nearly mid-way between Procyon and the three little stars which form Orion's head—and also of a line passed from Castor to α Leporis—in the middle of the Milky Way.
About 2' preceding, and 40' south of this, is a sprinkle of brilliant stars, registered 2 ♅. VII. in 1784, and described as tracing "winding lines around 12 Monocerotis."
