..

We add cautionary naturals before b flat1 in the 2nd demisemiquaver triplet and e flat3 in the last one. The first sign was added as early as FE (→EE), probably by Chopin's request, the second one in EE.

a flat1 twice in A (→GE)

f1 in FE (→EE) and GET
..

 A (→GE) has a flat1 as the 2nd and the 4th semiquaver. Chopin changed them to f1 in the proofing of FE (→EE). The relevant correction is also visible in GET.

b. 35

composition: Op. 27 No 2, Nocturne in D♭ major

..

Before the penultimate semiquaver in  A (→GE1) the  raising b flat1 to b1 is missing.  This obvious mistake was corrected in FE (→EE) and GE2.

composition: Op. 27 No 2, Nocturne in D♭ major

..

In A (→GE1) there are no naturals raising e flat to e and E flat to E. The accidentals were supplemented in the proofing of FE (→EE), yet the first one was mistakenly placed before the 6th note. GE2 has the correct text.

When correcting FE (→EE), Chopin added accents under bass notes in the middle of each of those bars. In EE, a vertical accent was used in bar 40, which is characteristic for that edition.
