Description. 
May 12, 1858. Close d. neb. 
May 14, 1851. pL; mE. ssp, nnf; has nucleus. 
May 12, 1858. Eather a B. ray ; bM. and mottled. Its p. arm is brighter than the f. one. 
A E. neb. about 2' p. 
May 1, 1854. F ; pL ; no nucleus ; mottled. 
Apr. 3, 1854. 3 neb. in line, and another S. neb. near the f. one. 
May 1, 1854. Has a cuired form between 2 *s, and in contact with them ; there is a 3rd 
smaller * close to the neb. on np. side. 
Mar. 1, 1851. B. in centre; E. 
Apr. 6, 1851. E. p. and f; r. Another vF ; 3' f. 
Apr. 19, 1849. 6 neb. found. 
May 3, 1851. E. 
Mar. 17, 1855. The atmosphere seems to exist. 
Apr. 28, 1848. Think the distance between the 2 neb. greater than in H’s drawing. 
Apr. 11, 1850. The 2 neb. not in a line, and a F. connexion 
siispected. Apr. 17, 1855. These 2 neb. are not in a Ime but 
parallel ; the distance between is considerable, but F. neby. 
suspected connecting them ; they have a very hazy look, and 
the edges are not well defined. May 14, 1855. Seen as on last time. May 8, 1861. 
Sketched; axis not parallel, but inclined at an angle of about 16°. Fig. 31, 
May 3, 1856. A B. S. ray sp, nf ; has nucleus. [Plate XXVIll. 
May 16, 18-55. Looks E. pB ; mbM ; nucleus. 
Apr. 13, 1850. vB; oval; E. np, sf; * in np. end. “Nova” near; vS. 
Apr. 13, 1855. mE. n. and s ; centre vB ; extremities F. 
Apr. 25, 1849. 1911 vS ; * close to right. 1912 rather F 
and vF. 
2 “ novae ” f, apparently comiected. 
Nucleus, and E. 
May 23, 1854. 2 neb. close together, n. and s. 
lC superb cl. 
Apr. 13, 1850. Yerj' remarkable ray, 12' or 15' long ; _ 
a, /3, y, and S are *s, of which a is F ; a long split .====== , 
precedes the nucleus. g 
Spiral ? 
About 15*' 12™ .i'R 1 A pair of new neb, about 15'asunder, np. and sf. The sf. one a pB. ray, 
33° 55' X.P.D. J the other F.and S, but neatly placed at one angle of a triangle of F. *s. 
Apr. 28, 1851. vlbM; E. p. and f.

Mar. 17, 1855. E. np, sf; bM ; not vF. 
F. dash of light. 
Apr. 3, 1854. E ; B. nucleus.

14, 1850. (A) Dark spaces round on either side of nucleus, 
seen at moments ; also a dark line running along the sf. edge, 
splitting off a part of neb, which has a B. knot to s, also some 
El-defined dark space at n. end. Apr. 5, 1851. (A) spiral ; a good 
deal of dark space round the nucleus, branches perhaps like 604.
