A second-grade Greenwich star, in the Whale's mouth, and closely double. A 3, pale yellow; B 7, lucid blue, the colours finely contrasted. With my instrument this beautiful object is certainly not so very difficult to measure, as the above discordancies would indicate; so leaving the unravelment of the anomaly to future inquiry on comparing my results with those of Σ. H. and D., I consider its fixity established. The amount of proper motion through space assigned to A, has been thus valued:
P.... RA -0".35 Dec. -0".20The Arabian astronomers applied the name of Kaff-al-jidhma, the maimed hand, to a group of stars forming the Whale's head; and which, though limited by Ideler to α Cet, δ Cet, λ Cet, μ Cet, and ξ Ceti, has been latterly applied exclusively to γ Cet. There are vestiges shewing that the Orientals had a large asterism here in very early times, probably before Cepheus and the Ethiopian plague were thought of. A line from β Andromedae through β Arietis, the centre of the three stars in the Ram's head, points nearly upon γ Ceti at about 25° beyond, or as far again; and it is nearly in mid-distance between Algenib and Rigel.
