Description. 
appendage is broadest and brightest. The ray is 12' or 14' long, and there is a F. # 
at a (Mr. Sto^tey was with me). April 6, 1856. 15' long, perhaps even longer ; the 
* opposite the nucleus is about two-thirds the breadth of the neb. distant.

April 14, 1852. A curious d. neb ; some other nebs. p. 
March 19, 1857. E ; bM ; L. but F ; * involved in p. edge. 
Looked for twice ; not found. Query, Is this 1358 and 1359 ? 
May 3, 1851. gmbM ; IE. sp, nf ; edges fade oif very gradually. 
April 24, 1854. pB ; has nucleus ; E ; F. ray f. April 25, 1854. Seen as last night, also 
the F. ray f ; about 50' p. is a B, E, pL. neb. f. a B. *. 
Sketched 3 times. April 10, 1855. Somewhat curved, like 2205. The s. branch is 
patchy, having 2 B. spots (see fig. 25. Plate XXVIII.) ; the n. branch is much the 
brighter. A S. p. the neb. About 6' or 7' n. of 1385 and a little f. is 1392, not so 
F. as Herschel describes it ; the brightest part seems eccentric, being nearer the nf. 
edge. From this B. part I suspect a curve round n. to sp. April 13, 1855. Seen as 
before. March 8, 1856. The comp. n. (1392) I suspect, as before, to be a F. spiral. 
March 27, 1856. Better seen than on any previous occasion ; the F. branch to the 
left extends round as far as the p. extremity of the B. branch. The comp. neb. 
suspected to have a twist in it, as before ; sketched. 
April 11, 1852. gvbM; E. np, sf. 
See the ‘Transactions’ for 1850. 
March 1, 1854. d. neb ; F. neby. connects them. 
April 22, 1854. A remarkable object; spiral? 
April 5, 1851. L; vB; comp. neb. pB. 
March 7, 1856. IE. nearly p. and f. 
Feb. 26, 1851. p. part is broadened out ; light imequal ; night bad. 
April 26, 1851. Herschel’s two neb. form one, the joining part in middle F, and vF. 
production of neb, as in sketch. April 9, 1852. Last year’s observation confirmed ; 
like a caterpillar on a leaf. April 20, 1857. I can confirm former observations in 
every particular, and think there are two additional *s in f. part. See fig. 26, 
Spiral? [Plate XXVIII. 
April 13, 1852. gvmbM ; S. * involved in f. part. 
April 15, 1852. gvmbM ; oval. 
Feb. 16, 1855. vB. ray; a dark band across on each side of nucleus, separating it from 
the extremities. Feb. 17, 1855. Sketched. Feb. 19, 1855. The dark spaces which 
are visible in finder are not black, but only portions of fainter neby. April 6, 1855. 
Seen as before ; dark lines very plain in finder. April 16, 1855. My sketch exagge- 
rates the dark lines ; they should be broader, and not so well defined. Mr. Stoney 
remarked a second dark fine across the n. branch near its extremity. Mar. 7, 1856. 
Observed. Mar. 18, 1857. Dark spaces far apart, and not absolutely dark ; suspect 
a dark space to right-hand side of nucleus. See fig. 27, Plate XXVIII. 
March 9, 1850. Another spiral; another neb. 15' p. Feb. 26, 1851. Spiral; 2 arms, and 
some *s in f. arm ; centre is B. 12' p. and a httle s. is another neb, E ; and 30' nf. is 
a 3rd, E. n. and s. April 15, 1858. vL. and vB. The centre itself is like anE. neb, 
with nucleus ; this centre is enveloped in an irreg. ring or rings 
of nebulou.s light, as in the accompanying rude sketch, which 
does not contain aU the details, sp. this object there is a S. » , _ . 
neb. E. np, sf. and very patchy, and I suspect it to have a F. ^ 
nucleus. May 3, 1858. I saw aU the details in last observation, 
except that there was only one * visible s. of nucleus instead of- ■ — 
two, but this is not quite so good a night. The surrounding 
ring of neby. is of irreg. shape ; it curves gently at S, but bends more sharply at y, where 
it is brightest. The centre seems to reach up to and blend with the neby. at S. 
April 9, 1852. Spiral; bears great resemblance to 1111. April 14, 1852.^ F. neby; 2' 
radius extends all round, in which I think I see traces of spirality which exist cer- 
tainly in the central part (Note by Mr. B. Stoney). A good night and speculum in 
good order would probably show this object distinctly. April 13, 1855. vlE. p. 
and f ; dark ring round the nucleus ; then B. ring exterior to this. The annulus, 
however, is not perfect, but broken up and patchy, and the object wiU probably turn 
out to be a spiral. There is much F. outlying neby. March 8, 1856. Annular at 
first look, but ring not perfect; centre vB.
