A neat double star, on the Dog's right ear; where a line through Orion's belt will meet it, at nearly 4° north-east of Sirius. A 5½, topaz yellow; B 9½, grey. This elegant object was discovered by Σ., and is No. 997 of the Dorpat Catalogue; but the earliest measures I met with are those of H., with his 7-foot telescope, which formed the only comparison until the arrival of Σ.'s great work, when the results were found to run thus:

    H. Pos. 341° 17' Dist. 3".63 Ep. 1830.18
    Σ.      343° 31'       3".22     1831.20
   [WDS     343°           2".90				 2017   ]
