Jan. 20, 1855. I see 2 *s in p. edge with |-inch single lens, The smaller component of 
a double * touches f. edge ; light mottled. On several occasions spirahty suspected,

Mar. 1 0, 1858. (Definition very good.) Nucleus stellar ; the brightest part of the neb. 
looks r. It is pL. and mottled ; suspected spiral.

Sketched 6 times. Spiral. Jan. 29, 1856. Very well seen; previous observations con- 
firmed. I have no doubt the neb. is a spiral. The f. half of neb. is the more ditfi- 
cult to see well. Mar. 10, 1858. WeU seen ; the whole neb. looks vB. and sparkling ; 
part is clearly r; my former conjectures as to its shape confirmed. I used the high- 
est single lenses. Mar. 11, 1858. (Definition very good.) Observed with same 
results as on last night.

-Ian. 10, 1856. Not vS. but wE. and flickering. Eeb. 1, 1856. Nucleus and * close to s. 
side of it, and two very indistinct branches of neby. Erom the tenour of the observa- 
tions no doubt it is a spiral ; the twist of the branches fully confirmed.

Nov. .30, 1850. S. * in its nf. edge, perhaps not connected with the neb. The neb. had a 
brush-like appearance. Eeb. 1, 1851. Dark space f. the between neb. and like 
the “ snowdrop ” neb. (see fig. 10, ‘Transactions’ for 1850).

Dark space suspected in centre, but never fully confirmed. Eemarkable for extreme
