A bright star, with a minute distant companion, on Orion's right shoulder; and it is one of ♅.'s insulated objects. A 2, pale but clear yellow; B 15, grey; a third star precedes by about 34s, in the sp quadrant.

γ Orionis was rejected from the Greenwich List in 1830, there being no fewer than four others of this constellation retained as standards : it is called Bellatrix, or the female warrior, and is the smaller of the two upper stars in Orion. The gender of this star puzzles Hood, who knoweth not why it should be female, "excepte it be this, that women born under this constellation shall have mighty tongues." Bellatrix is the Al-nájid, or subduer, of the Alphonsine Tables; but Ulugh Beigh calls it Al-mirzam al-nájid, though other Asiatic astronomers give the first epithet, Al-mirzam, to α Orionis. Hyde, in his notes on Ulugh Beigh (Syntagma I. 59), explains the Arabic words as signifying "the conquering lion;" but his interpretation is doubtful.

γ Orionis is the north-west star of the four at the corners of this asterism, so to speak; and an ideal line, carried from Sirius over Aldebaran to the Bull's ear, passes over it in the mid-distance; the rhymester then directs,

From Bellatrix now pass a line,
to Betelgeuze the red,
And, to the north, three little stars
will mark Orion's head.

A friend considered my distance as "much too large," and the colour of A to be "reddish." On referring to Mr. Challis, that gentleman examined the object with the great Northumberland equatoreal, pronounced A to be "yellowish," and made the following measures:

    Pos. 148°04'  Dist. 180".46  Ep. 1841.19
   [WDS  144°           178".00      2009   ]

Bellatrix has a small though sensible movement in space; but the doctors differ respecting its amount and direction. Thus the values of those most worthy of attention are the following:

    P....  RA -0".17  Dec. -0".03
    B....     +0".09       +0".01
   [Hipparcos -0".00811    -0".01288]
