nebula ; they are extended in the parallel of the equator 

 nearly. 



No. 486. R. Asc. 18^ 39™ 20^ S. Pol. Dist. 47° 44'. 



A very singular body resembling a star, with a very faint di- 

 luted atmosphere, 8" or 10" diameter; it is paler than a star 

 of the same magnitude, and precedes a pretty bright star. 

 No. 501. K. Asc. 17*^ 37"^ 48^ S. Pol. Dist. 48" 4P. 



Two very small stars, with a small nebula between them ; 

 both the stars are involved in the nebula, but the nebula is not 

 in a line between the stars. 



No. 507. R. Asc. 0^ 6™ 50^ S. Pol. Dist. 49° 50'. 



A beautiful long nebula, about 25" in length ; position north 

 preceding, and south following, a little brighter towards the 

 middle, but extremely faint and diluted to the extremities. I 

 see several minute points or stars in it, as it were through the 

 nebula : the nebulous matter of the south extremity is ex- 

 tremely rare, and of a delicate bluish hue. This is a beauti- 

 ful object. 



No. 508. R. Asc. 5^ 7"^ 0^ S. Pol. Dist. W 45'. 



An exceedingly bright, round, well-defined nebula, about 1|' 

 diameter, exceedingly condensed, almost to the very margin. 

 This is the brightest small nebula that I have seen. I tried 

 several magnifying powers on this beautiful globe ; a considera- 

 ble portion round the margin is resolvable, but the compres- 

 sion to the centre is so great, that I cannot reasonably expect 

 to separate the stars. I coxipared this with the 68 Conn, des 

 Terns, and this nebula greatly exceeds the 68 in condensation 

 and brightness. 



No. 564. R. Asc. 9'^ 8"^ IT. S. Pol. Dist. 53° 53'. 



A pretty large faint nebula of a round figure, & or 8^ dia- 

 meter ; the nebulosity is faintly diffused to a considerable ex- 

 tent. There is a small nebula in the north preceding side, 

 which is probably a condensation of the faint diffused nebulous 

 matter ; the large nebula is resolvable into stars with nebula 

 remaining. 



No. 573. R. Asc. 18^^ 49" 15«. S. Pol. Dist. 53° 10^ 



A beautiful bright round nebula, about Sy diameter, mo- 

 derately and gradually condensed to the centre. This is re- 

 solvable. The moderate condensation, and the bluish colour
