IC 4600 may be the small asterism of three stars which I've noted in the position table; it is close to the nominal position. Or the IC object may be the small, round galaxy 2min, 10sec of time preceding the nominal position. This suggestion comes from ESO-B, and was picked up by Wolfgang Steinicke as well. There is also a linear asterism of three stars north of the nominal position that I've put into the position table. Or IC 4600 may be a defect on the 4.5-hour Bruce plate. Hopefully the plate still exists so that it can be checked someday.

The only other object which Stewart found on this particular plate is IC 4596. That is at its nominal position, and matches Stewart's description very well.
