NGC 178 = IC 39. The IC identity is not in doubt. Javelle's micrometric measurement reduces to within a few arcsec of the modern position.

The NGC number, though, comes from one of Ormond Stone's Leander McCormick discoveries with its typically bad RA. Stone's declination is fortunately close, and his description "F, S, mE 0 deg, bM, faint wing sp" fits the galaxy perfectly. The "faint wing" is, in fact, one of the arms of this object. I wonder if this is a superposition of two galaxies, or an interacting system.

Stone has left a sketch of his nebula -- my rather poor copy of it shows the "wing" faintly. Unfortunately, the sketch shows only the galaxy; no nearby stars are included, so the identity is not quite pinned down. At least the galaxy itself is oriented along the north-south axis of the sketch with the "wing" apparently stretching off towards the southwest.

Herbert Howe found the galaxy 1min 37sec following Stone's position, so the corrected position made it into the IC2 Notes. Unfortunately, Dreyer did not notice that the object is the same as IC 39, so the identity of the two numbers was not published until one of the Helwan observers noticed it.
