A neat double star in the Galaxy, over the aplustre of the Argo's poop; where a line sent from Pollux through Procyon, and 28° beyond, will hit it; as will a cross line from Orion's sword-cluster carried through Sirius, and 14° into the south-east quarter. A and B, both 6, and both topaz-tinted. This appears to be No. 19 of ♅.'s 145, registered in 1784; and though the results of Piazzi's circle observations do not quite coincide with my micrometer measures, the star here noted as B, adjusting the quadrant, must be his No. 147 of Hora VII. Sir James South, No. 552, gives these data:

    Pos. 284° 53'  Dist. 9".01  Ep. 1825.01
   [WDS  118°            9".90      2016   ]
