In A Chopin did not check the notation of accidentals in these bars. In each of them the 
returning c4 in the 4th chord is missing, as well as the flats returning e
1 in the 5th chord and b3 in the last one. In FE (→GE,EE) all necessary accidentals were added, same as cautionary naturals before c1 and flats before b. In FE, however, the raising e3 to e3 in bar 49 was overlooked, which was corrected in GE and EE, as well as in FED. Moreover, we add a cautionary before a2 in bar 49; the accidental was already added in GE and EE4 together with a less justified cautionary before a.
