Description. 
Eeb. 1, 1851. f. division the brighter. 
Mar. 8, 1856. mE ; certainly dark 
SteUar pt. or micleus E. 
Jan. 1850. Probably very remarkable ; bad night. 
Mar. 3, 1851. p. division pretty well seen. 
spaces on each side of nucleus, but not well seen ; that on f. side is the more distinct. 
Sketched roughly 3 times. 
Jan. 21, 1855. pL ; considerably E ; BM, but no nucleus. 
Mar. 28, 1 856. About 3' apart ; both F. and of nearly equable light. The n. one is a 
long narrow ray np, sf ; the other is oval sp, nf. 
A S. comp. dist. about 5' or 6'. 
April 9, 1852. I suspect a dark curved passage sp. centre. Mar. 15, 1855. Light mottled ; 
I suspect a knot in p. and one in f. edge. Has a spiral appearance. 
Mar. 12, 1855. Has a shai-p B. E. nucleus in a disc of F. mottled neby. 
Mar. 17, 1855. Oval; major axis nearly p. and f; nucleus vB. 
Feb. 22, 1857. mE; B. nucleus; anns F ; patchy. Mar. 23, 1857. pL; nucleus vB, and 
has a sensible disc ; arms vF. and patchy. 815 is F, nearly E, IbM. 
E ; gbM. 
Query, is there a F. ring roimd it ? 
Mar. 1, 1854. Query, an oval spiral? 
April 1.3, 1852. Neb. does not appear to reach the *. 
Very like H. 2172. See figure. Mar. 29, 1856. The nucleus projects into the space 
along sp. edge ; outside this dark space there is F. neby, which I see j oining the 
neb. at n. A F. * at the opposite extremity. 
1 3, 1851. Light mottled; vBM ; knot in p. branch. 
April 13, 1850. But one * seen. Feb. 1, 1851. 2nd * not seen; sky milky. March 3, 
1851. 2nd * not seen ; sky milky. March 5, 1851. 2nd * not seen. March 7, 1851. 
2nd * not seen. April 3, 1851. 1st * only seen. Jan. 27, 1852. Only one ^ seen. 
March 12, 1852. Only one * seen. March 13, 1852. Only one * seen. March 20, 
1854. 2nd * not seen, nor any of the F. details. March 30, 1856. 2nd * not seen, 
nor minute details. March 24, 1857. 2nd * not visible. March 8, 1858. 2nd * not 
visible, nor minute details. N.B. The 2nd * has not been seen since March 9, 1850, 
March 17, 1855. mE. p. and f; vB. centre; the n. edge of central part seems sharpest, 
and outside it again I think there is F. neby ; in f. edge. A rough sketch repre- 
sents it like 2172. 
Suspected spiral, but a vF. object. 
844 is a B. nebulous disc in a F. oval neby. 
Mar. 19, 1852. E. np, sf; vB. centre. 
Feb. 18, 1852. vbM ; IE. 
Mar. 29, 1856. S ; pB ; R ; mbM. 
“ Nova ” near ; both are S ; F ; IbM ; and 851 has nucleus. 
Mar. .31, 1848. Curious neb. with B. nucleus at left; a little above and towards the 
right is a streak ; spiral ; resolved very well about the nucleus, but no other part. 
From the right, and apparently .sjjringing from the nucleus, a vF. portion of neb. 
extends for nearly 1.5', gradually melting away. Ajjr. 3, 1848. Observed with the 
same results as on March 31st. April 17, 1849. 2 sfr-s near nucleus, one sp, the 
other sf. it. Feb. 25, 1854. Suspect dark spaces on either side of nucleirs. Mar. 1, 
1854. Neb. mottled ; p. observation confii’med. 
2 neb. found ; the p. one has a sudden vB. nucleus, and is IE. np, sf ; the other is about 
15' f; S; R; pF ; vlbM. 
Suspected darkness on either side of nucleus ; E. See fig. 16, Plate XXYII. 
Apr. 15, 1852. R. disc, BM, with vF. neby. round it of mottled character ; probably it wiU 
be seen as spiral on a fine night. Mar. 30, 1856. Spiral with, I think, two arms, thus : 
these arms arc broken and of unequal light ; there are B. patches at a, ft, (3^^^ 
and y respectively ; a F. p. at S. Apr. 6, 1856. Seen as spiral. The f. 
branch comes douTi past the other, doubtless over it as at a, and seems to s w 
originate from the p. side of nucleus. Mar. 24, 1857. The spiral arms 
are eeF, but there is no doubt of their existence as described in previous 
observations.
