IC 1346 and IC 1354 = IC 1350. Javelle found these two galaxies on 7 August 1891. His positions with respect to a star that he called "BD -14deg 5910," however, refer to blank patches of sky. He went over the area again on 26 July 1892, finding only one object, IC 1350. Again, he used the "same" BD star as his comparison star -- but this time, his position for the galaxy falls within 2 arcsec of the GSC position for MCG-02-53-021.

Where are his first two galaxies? If we look at Javelle's relative positions for the two, we find that the relative GSC positions of MCG-02-53-021 and MCG-02-53-019 are exactly the same. If we assume that these are in fact IC 1346 and IC 1354, then the offsets Javelle gives should point to the same star. In fact, they do: The star is GSC 5782-1182, about 5.5 sec preceding and 5.5 arcmin south of BD-14 5910, Javelle's nominal reference star. The position for the more southern star, combined with Javelle's offsets, point to the MCG galaxies as the ones which he actually found. Since his "third" object in the area, IC 1350, is also one of the galaxies, it is clear that it is a repeat observation of IC 1354.
