b. 155

composition: Op. 38, Ballade in F major

..

We add cautionary naturals before the G1-G octave in the main text.

b. 155

composition: Op. 26 No 2, Polonaise in E♭ minor

in GE2 (→GE3GE4) & EE2

No marking in FE (→GE1,EE1)

..

The omission of the  indication at the beginning of the bar in FE (→GE1,EE1) can be intentional, hence we do not include it in the main text. In GE2 (→GE3GE4) and EE2 the indication was added, most probably on the basis of comparison with analogous bar 51.

b. 155

composition: Op. 26 No 2, Polonaise in E♭ minor

..

A (→FE) overlooked the flats restoring A and a on the 3rd beat of the bar. In the remaining editions, the inaccuracy was completed.

c2 in FE (→EE), contextual interpretation

..

The structure of the figuration in the entire passage in the L.H. (bars 153-156 and 157-160), and particularly the comparison with analogous bar 159, indicate a mistake of the copyist in this place. The absence of a correction in GE may be attributed to the absent  before this note (although in a similar situation four bars later, a  before the respective note – c2 – was added). The sign is absent also in the majority of the sources featuring the note at the correct pitch – it was added only in EE2

f2-b2 in GC (→GE), FE3 (→FE4) & EE2

g2 instead of f2 at the last quaver of the bar is certainly a mistake of Chopin in [A]. It is proved by the  before the note, present both in FE1 (→FE2) and GC, which originally also included g2. Chopin corrected the mistake in GC and the proofreading of FE3 (→FE4). The erroneous version was passed down to EE1, in which it was revised, by deleting the , which was superfluous before g2.
