Such are [mu] Draconis, a beautiful miniature of Castor; [gamma]^{1} and [gamma]^{2} Draconis, a wide double, the distance between the components being nearly 62" (both grey); and [gamma]^{1} and [gamma]^{2} Coronae, a naked-eye double, the components being 6' apart, and each double with a good 3-inch telescope.
We turn, however, to another region of the sky.

Low down, towards the south is seen the small constellation Corvus, recognised by its irregular quadrilateral of stars.

Of the two upper stars, the left-hand one is Algorab, a wide double, the components placed as in Plate 3, 23".5 apart, the larger of magnitude 3, the smaller 8-1/2, the colours pale yellow and purple.
There is a red star in this neighbourhood which is well worth looking for.

To the right of Corvus is the constellation Crater, easily recognised as forming a tolerably well-marked small group.

The star Alkes, or [alpha] Crateris, must first be found.
