Observations of Nebule and Clusters of Stars. 59 
1851, Jan. 8. Dark ring appeared unbroken all round. 
1851, Jan. 24. Lord R. saw split in f part, but would not have remarked it had 
he not seen it before. 
1851, Nov. 29. Ring seen all round, but most distinctly on s side. 
1852, Jan. 20. Indentation on f side of central part seen by Lord R. 
1855, Jan. 18. Could not see any indentation in f side of central part, but could 
see that the dark ring was broader there by encroaching on the outer neb- 
ring. With } inch single lens [power about 1300], I thought I saw a dark 
space np central *, but it requires confirmation. Could perhaps this dark 
space be a distinct portion of a second dark ring close round the * ?? 
1855, Jan. 20. I have again a vague suspicion of a 2nd dark ring interior to the 
other, certainly a dark space or spaces seen at moments round p and np side 
of *. Dark ring seen just as on Jan. 18. 
1855, Feb. 14. Dark space seen distinctly at times, np the * and susp. all round 
from sp ton. Widening of dark ring f seen as before. 
1856, Feb. 1. Strong suspicion of a 2nd dark ring as last year, * not quite 
central with respect to the supposed ring, but nearest sp side. 
1860, Dec. 16. I think it is a right handed spiral. 
1860, Dec. 19. p side looks brighter. 
1861, Jan. 15. Blue. I think there is a break in the outer B ring nff *. 
Spiral ? 
1861, Feb. 1. B ring is p andf fainter than n ands, dark spacen ands is 
difficult to see (if it exists n 4). 
1862, Jan. 25. Dark ring seen all round except nn f * at 6 and 
I strongly susp. a break in the annulus at a, neb is brightest 
between $ and y, and from a to y is by far the faintest 
portion of annulus. 
1864, Feb. 3. Opening at a seen well, also the darkness p *. 
There is a slight decrease in light in the B annulus spp *, the remaining 
portion of annulus is r, st seen at times in it. I could see no darkness at £, 
so this neb. seems to be a spiral. 
1873, Feb. 20. vS dark vacuity round thestar inside inner neb. ring. Diameter 
of dark ring 211, outside diam. =43'°7.

Diam. ns =47''6 (2). Nucl.=* 10 m., s edge of neb. is the brightest. 
(XX XVII. obs.) 
1867, Feb. 22. Counted 70 st nearly contained in one field 16’ diam., about 10 
of them are of 11 mag., rest smaller. (I. obs.) 
1866, Nov. 13. Not found. 
1867, Jan, 28. I am certain there are no B neb. near this place, many S groups of st. 
1867, Jan. 29. Some S groups of st must have been mistaken for neb., one was 
in fact barely resolved in the finder-eyepiece. (III. obs.) 
[S clusters seen by d’Arrest and Schultz. Why are they entered as bright in the 
G. C.? Bond calls them “Two F nebulae.” | 
1856, Jan. 30. Neat S Cl, nearly R, v8 st closely packed but not running up 
to a blaze. Looks in finder ike ar neb. (I. obs.) 
1857, Jan. 21. F, vS, * 13-14 mag. close to n edge, another * f. (I. obs.) 
1877, March 3. Only 4 st 9... 11 mag. and some fainter ones. I suppose 
there are millions of such clusters. (I. obs.)
