COMA BERENICES (kō'-ma ber-e-ni'-sez)-BERENICE'S HAIR.

LOCATION-A line drawn from Regulus to Zosma, in Leo, and prolonged an equal distance, strikes this fine cluster, which is 18 degrees northeast of Zosma.

The group lies well within a triangle formed by Denebola, Arcturus in Boötes, and Cor Caroli in Canes Venatici, which triangle is the upper half of the Diamond of Virgo.

Twenty or thirty stars in this group can be counted with an opera-glass, and the group can be easily distinguished with the naked eye, when the moon is not visible.

CANIS MINOR (kā′-nis mī′-nor)—THE LESSER DOG. (Face

West.)

LOCATION-Procyon, the little dog star, lies about 23 degrees south of Pollux, in Gemini. A line drawn from Nath, in Auriga, to Alhena in Gemini, and prolonged about 18 degrees, reaches Procyon.

Procyon is equidistant from Betelgeuze in Orion, and Sirius in Canis Major, and forms with them an equilateral triangle. It forms a large right-angled triangle with Pollux and Betelgeuze. The light from Procyon is golden yellow. Four degrees northwest of it is the third-magnitude star Gomeisa. The glass shows two small stars forming a right-angled triangle with it. Procyon was distinctly mentioned by Ptolemy.

CORVUS (kôr′-vus)—THE CROW. (Face South.)

LOCATION.-A line drawn from the Bee Hive, in Cancer, through Regulus in Leo, and prolonged about 40 degrees, ends near the conspicuous quadrilateral which distinguishes Corvus. The brightest star in this region of the sky is Spica in Virgo. It lies about 10 degrees northeast of Algorab.

() is a double star for an opera-glass. A faint pair of stars lie close below and to the west of (ß). The Crow is represented as standing on, and pecking at, the coils of Hydra. The star Al Chiba is in the Crow's bill.

Corvus was known as the Raven in Chaucer's time.
