b. 52

composition: Op. 35, Sonata in B♭ minor, Mvt II

..

In FE1 and GC the bottom note of the 1st chord in the R.H. is an erroneous a1. The erroneous notation must have been in [A], which is confirmed by an identical mistake in the recapitulation (bar 240). The patent mistake was corrected in the subsequent FE (→EE) and GE, which can be almost certainly ascribed to the revisers.

composition: Op. 35, Sonata in B♭ minor, Mvt II

No sharps in GC (→GE) & FE1 (→FE2EE1)

Sharps in FE3 (→FE4) & EE2

..

In the main text, we include the added in the proofreading of FE3 (→FE4) – most probably by Chopin – sharps raising the f1-f2 grace note to f1-f2. According to us, it was probably a correction of a mistake. Similarly in the recapitulation – bar 242

b. 56

composition: Op. 35, Sonata in B♭ minor, Mvt II

..

Before the octaves on the 2nd and 3rd crotchet of the bar in FE1 (→FE2FE3) there are no accidentals. The patent inaccuracy of the composer was corrected to a varied extent in EE1 (the naturals of and C) and FE4 (the naturals of and C1-C). The totally correct notation is included in GE and EE2. Same in bar 244.

b. 57

composition: Op. 35, Sonata in B♭ minor, Mvt II

Chord with c2 in GC & FE1 (→FE2EE1)

Chord with c2 in GE, FE3 (→FE4) & EE2

..

The chord with c2, although completely possible from the harmonic point of view, is, however, most probably a result of Chopin's mistake, as the d-f-a-c (a-c-e-g) diminished four-note-chord introduces the B minor key, which Chopin indicated with an enharmonic change in the previous bar. In this context, an omission of a  is highly likely – cf. the note in bar 56. The natural added – probably by Chopin – in FE3 (→FE4) is, therefore, probably a correction of a mistake.

b. 95

composition: Op. 35, Sonata in B♭ minor, Mvt II

..

In GC (→GE) and FE1 (→FE2EE) there is no accidental before the top most note of the last chord. This patent inaccuracy of Chopin notation was corrected in FE3 (→FE4), at the same time, however, the  raising a1 to awas overlooked.
