600 262 1848, Dec. 22. <A blue spiral ? 
1849, Jan. 14. Spiral. 
1851, Oct. 29. The central part is flatter on the f side, and outside part vF. 
3 B spots in the outer part, sp, np and nf the Nucleus, are perhaps parts of 
spiral arms ?? 
1851, Nov. 21. Thes knot isa*. The B patches give the neb. the appearance 
of having a dark space all round the B central part. 
1851, Nov. 24. The central part is, I am nearly sure, spiral. 
Phil. Trans. 1861, pl. XXV. fig. 6]. 
1852, Jan. 13. Spiral form of centre seen. 
1856, Nov. 29. Details of drawing seen very well. 
Sketched. [See 
1858, Jan. 10. I can see nothing more than is given in the sketch, which appears 
to me correct, though perhaps it defines too well the edges of the B central disc. 
1862, Nov. 24. The central B portion seems almost quite separate from the 
fainter part.

1855, Oct. 16. Fine oval neb., has Nucl., light mottled, sometimes I 
thought I saw a dark bay n of Nucl., certainly the neb. is brighter 
along n and nf side than in the part intervening between that and 
the Nucleus. <A * at 62?

1874, Dec. 3. Nucleus is sharp, v1 Ens, probably spiral (independent sketches 
by both observers agree). J think there is a dark space in the surrounding 
neby. sf the nucleus. A v F * inv. south, ill defined, may be a second nucleus. 
B* in Pos. 112°-0 (3). Dist. 97’ (1 meas. through clouds). See Pl. I.

another at y. 
1856, Noy. 28. Has ragged edge and mottled look, Lord Rosse thought it a Cl.
