A broad dark lane runs along the spiral to the east of the nucleus. Most of the
nebular matter is to the west of this lane, there are no prominent condensations
other than the nucleus. See Abs. Eff. 18 s.n. A very compact spiral 2' x 1'; the
nucleus ...

4282 (18) 5866 ( 5) Lane inclined to major axis. 4710 (28) 4402 (11) - 1888 (29)
The narrow, somewhat irregular lane 4244 (12) is lost in the reproduction.
Merging imperceptibly into the group just given are a number of spirals seen
almost but ...

6928 (27) 6690 (35) 4429 (38) Fine narrow lane near nucleus; compare the
similar nebula 4526 (17). 3169 (39) Lane quite clearly defined. 4216 (41) Long
lane, fairly clear cut. 4826 (54) A remarkable case; lane seems absolutely black
