WITH A FOURTEEN FEET REFLECTOR. 199 



45. Strongly suspected.— \. A slight brightening up of the nebula where 

 enclosed by the line 1^, as if beginning to break up into a still farther subdi- 

 vision. This, if real, subdivides the dark branch a, into two, in its outward 

 course. (Art. 17, Aug. 10.) 



3. The filling up of the clefts with faint nebulosity. 



3. The same between the northern and southern nebula, faintly uniting the 



two. 



46. Slightly suspected.— I. The angular irregularity on the south and fainter 

 side of the part C, rendering it not unhke a shell with a sub-angular margin. 



Nebula h. 2008. 



47. Things certain. — 1. The "resolvable knot" mentioned by Herschel 

 (Art. 58, Phil. Trans. 1833,) near the star 18, is isolated, or nearly so, from 

 the rest of the nebula. (Not seen resolvable by us. See Art. 18, Aug. 10.) 



2. The smaller knot is apparently not affected with this peculiarity. 



3. Of the faint bend or loop at the right hand, the following half is brighter 

 than the preceding. 



4. The bright branch fades gradually away to the left, terminating near the 

 star 36 ; it is convex upwards. 



5. The external angle of the nebula stretches down from the star 17, towards 

 the north, preceding much farther than in Herschel's drawing. (Art. 18, 

 Aug. 10.) 



6. The bend in the drawing of Sir J. Herschel is too large, especially in a 

 vertical direction, when compared with the bright following branch. (Art. 18, 

 Aug. 3 and 14.) 



48. Nearly certain. — 1. The bright branch is more definitely bounded on its 

 upper or southern side, than upon the lower. 



2. From the larger knot at the internal angle of the nebula, a faint ray 

 proceeds as far as star 25. (Art. 18, Aug. 7 and 10.) 



3. The upper margin of this ray is tolerably definite, and thence it spreads 

 downwards till it mingles with the brightness below. (Art. 18, Aug. 10.) 



4. The " resolvable knot " of Herschel has either a second nucleus, or in- 

 volves a faint star (18) in its upper margin. (Art. 18, Aug. 14.) 



5. The partially vacant space in which it is situated is closed in by the ne-
