Nov. 23, 1848. Coarse, cl. strongly honey- combed. Would probably look annular with 
eccentric eyehole if it were far enough to be a neb. Nov. 21, 1851. The honey- 
combed appearance is caused by the disposition of the brighter *s ; no spiral arrange- 
ment. 
Jan. 17, 1855. r. Nov. 28, 1856. Edge ragged. 
Dec. 16, 1848. A multitude of nebs, knots in the neighbourhood, principally p ; counted 
15 ; many more. Dec. 8, 1855. One of them F ; has a # close sf. and looks like a 
snowdrop. 
Nov. 24, 1854. Two S. E. neb. ; both hM.

Jan. 17, 1855. d. neh. ; both vS. and bM. 
Dec. 26, 1856. The p. one is vF. and light mottled. Oct. 7, 1850. 1st appears divided, 
and preceding part has a minute *. Jan. 22, 1851. f. the 3rd; 14' is “nova.” 
Oct. 31, 1856. A fine d. * in a loose cl. 
Oct. 26, 1854. S; E; bM. 
Cluster. 
Sketched five times. Jan. 13, 1852. New spiral of an annular form round the #, which 
is central. Brightest part is sf. the * ; spirality is vF ; but I have no doubt of its 
existence. Oct. 7, 1855. Annular, but with a break in s. side of annulus, or perhaps 
spiral. Oct. 31, 1856. I feel certain of a dark space nearly p. the central *, but 
the shape of the whole is only conjectural ; there is a * plain np. the neb. Dec. 7, 
1857. Not vF, and the break in the s. side of the ring of neb. quite easily seen; 
between this ring and the central # is not black, but filled with more F. neby. Jan. 
9, 1858. Observed for a sketch ; last observation correct as to shape ; the brightest 
part is sf, and the next brightest is on the opposite side, and with i-inch single 
lens the whole annulus has a mottled look. Jan. 13, 1858. The whole 
ragged and irregular, and the whole neb. much mottled. See fig. 7, Plate XXV. 
Dec. 16, 1854. vF; S; E; IbM. 
Sketched five times. Jan. 2, 1851. Dark space sf. neb. ; though I did not see the F. neby. 
beyond the channel, I conjecture that it exists and fades off imperceptibly, some- 
what like the drawing. Jan. 22, 1851. Observations of Jan. 2n(i confirmed; 
F. neby. seen; B. part r. Nov. 29, 1851. Last season’s observations confii’med as to 
shape. Dee. 22, 1851. Previous observations confirmed. Jan. 13, 1852. eisd; 
^ is the angle of the brightest part. See fig. 8, Plate XXY.
