Observations of Nebule and Clusters of Stars. 153 
G. C. | h. & H. | - a 
1851, Aug. 24. Annular, centre very suddenly darker than the rest, vS * in 
np edge of central part. The np edge of neb is very vaguely defined and 
less bright than the other edges ; a pB * outside nf edge. 
1855, Aug. 8. Query, a * on np edge; s edge of neb is the brightest and best 
defined. (VII. obs.) 
4498 2042— | 1854, July 22. An oblong Cl, the brightest of the st form a sort of zigzag line. 
Wil, és (II. obs.) 
4499 2043= | 1851, Aug. 1. 4st in neb, 2 more on p edge. 
VI. 38 | 1855, Aug. 8. p B and of irr outline, 3 st plainly seen, susp more smaller ones. 
1862, July 29. Sketched. (IV. obs.) 
4507 2045— | 1855, Aug. 15. pB, R centre in a disc of F neby, which seems to reach a good 
TIT. 744 distance outwards, involving either a * or a knot spp & a * nnp. A * susp 
closely np centre. Seen through light clouds. (III. obs.) 
4508 2046 | 1854, July 22. L & Ri but very straggling Cl, neighbourhood yv Ri in stars. 
(I. obs.) 
4510 2047= | 1850, Aug. 28. v B, blue planetary neb, edges not sharp, a little darker in the 
IV.51 middle, 
1851, Aug. 1. The dark part is a little np middle. 
1855, Aug. 15. Has a hazy, indistinct outline like h 1970; I thought the 
darkuess in centre was 1E ns. 
1857, Aug. 13. Not seen decidedly annular, but its outer edge is certainly 
brighter than the centre, especially on np side. Not quite R, v1E nearly ns ? 
4511 2048 | 1871, Sept. 4. A most gorgeous Cl, st 12...15m, full of holes. (IV. obs.) 
[Plate V.] 
4512 2049— | 1855, Aug. 8. Loose Cl of a few B st and some smaller ones. (II. obs.) 
VIL. 18 
4513 Il. 878 | 1873, Sept. 15. Probably biN, Pos. 171°-8 (2), Dist. 40-6 (5), s one vF, 
svmbM almost to a * 17m,n one larger and brighter, gbM. A F object 
spp, another ssp; two vF ones farther away sp, np sf of one another. Clouds. 
1875, Aug. 3. pB, irr R with a F * or perhaps a second Nucl closes. Sev F 
objects near, but definition bad, speculum strained. D * (10m & F comp n) 
Pos. 354°-1 (3), Dist. 208”-2 (38). 
1875, Aug. 5. The faint objects sp are certainly stars. The object close s of 
the Nucl is a * inv in neby. The neb looks very r, like a distant Cl, Sev 
eF stp & sp. (III. obs.) 
4514 2050= | 1848, Ang. 23. Seemed JE 325°+, rather less defined and fainter at sides, 
IV. 73 especially n. 
1849, Aug. 17. Annular and gibbous, n edge being flatter ; the dark space not 
very easily seen. 
1850, Aug. 28. A very remarkable object, probably analogous toh 450. The 
dark ring is not easily seen, but there can be no mistake about it, seen by 
Lord R. and myself, my brother [G.J.8.] saw it dark under [p] the central *. 
1851, July 26, and Aug. 22. 8, E npsf, ring like h 450 seen at moments on p 
& s side of Nucl which is stellar. 
1862, Aug. 2.. The * is not central and the nf side seemed more sharply defined 
than the sp one, and I fancied I saw F neby around the latter side ; p the 
Nucl I saw a slight darkness. (VIII. obs.) 
4515 2051= | 1876, Aug. 14. Rich part of the heaven, many 8, P,1C Clusters, none re- 
Wil, 733 markable. (1. obs.) 
4516 | 2052— | 1876, Aug. 22. Cl, L, pRi, about 50 st 1l...m. (I. obs.)
