THE STELLAR UNIVERSE. 



Fig. 45. 



Fig. 46. 



In fig. 46 it is given as shown by Lord Eosse's telescope, 31st 

 March, 1848. Described as a curious nebula, nucleus resolvable, 



having a spiral or annular 

 arrangement about it. It 

 was also observed with the 

 same results on the 1st and 

 3rd April. 



A nebula, situate in E A 

 15 h 2 m , N P D 33 35', is 

 shown in fig. 47, its length 

 being 50" and breadth 

 20". 



This nebula was not 

 figured by Sir John Her- 

 schel ; but is described by 

 him as an object very 

 bright, and growing much 

 brighter towards the 

 middle. The drawing re- 

 presents the object as seen 

 in Lord Eosse's telescope, 

 in April, 1848. It is de- 

 scribed by Lord Eosse as a 

 very bright resolvable ne- 

 bula, but that none of the 

 component stars could be 

 distinctly seen even with 

 a magnifying power of 

 1 000. A perfectly straight 

 longitudinal division ap- 

 pears in the direction of 

 the major axis of the ellipse. 

 Eesolvability was strongly 

 indicated towards the nu- 

 cleus. According to Lord 

 Eosse, the proportion of 

 the major axis to the minor 

 axis was 8 to 1 ; much 

 greater than the estimate 

 of Sir John Herschel. 



In figs. 48, 49 are given 

 two views of the same 

 nebula by Sir J. Herschel 

 and Lord Eosse. Its situa- 

 tion is R A 12 h 33, ra N P D
