The nucleus is almost stellar; there are a few condensations. Moderately bright. 5 s.n. Minute oval patch 0:2 long. Vol. VIII, Plate 51. Very bright, 3' x 1' in p.a. 125°. No spiral structure is discernible, but it appears to be a spiral of the Andromeda type seen edgewise. Its most striking feature is a narrow, clear-cut dark lane along the middle, making a slight angle with the major axis. See Abs. Eff. 37 s.n. Almost stellar. A faint oval 0:8 long; probably spiral.

A rather bright spiral of S-shape, 18 long. The whorls are rather irregular, with numerous condensations, which are not stellar.

Of globular type? 0 s.n. A wonderful example of a dark nebula, lying in a remarkably dense region of the Milky Way. Discovered by Professor Barnard in 1883. Of rather irregular contour, about 6' x 4'. The most striking portion of this object is the roughly circular protuberance at the southwest corner; here the edges are defined with almost perfect sharpness, and there is an astonishingly abrupt transition from a region filled with faint stars to one absolutely blank. At this point one can really "see" the sharp edge of the dark body. On the eastern edge the transition is somewhat less abrupt. See Abs. Eff. 0 s.n.
