b. 225

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

in GC (→GE) & FE1 (→FE2,EE1)

e in FE3 (→FE4) & EE2

..

The change of to e is undoubtedly a result of Chopin proofreading of FE3 (→FE4).

b. 228-229

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

No accidentals in GC & FE1 (→FE2EE1)

Naturals in GE, FE3 (→FE4) & EE2

..

The absence of the naturals raising g(1) to g(1) is almost certainly a mistake of Chopin who partially corrected his error in the proofreading of FE3 by adding a  on the 2nd crotchet in bar 228. In FE4 the second necessary  was added, yet both signs are only in GE and EE2.

b. 230-231

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

..

The natural before the 5th quaver in the L.H. in bar 230 (c1) was added only in GE2. The natural before the 1st quaver in bar 231 (d1) is absent in FE; it was added in EE. The sign is also in GC, in which it is added by Chopin's hand (in bar 43), and in GE, which is based on it.

b. 232

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

..

In GC and FE1 (→FE2FE3) there is no  before the top most note of the 3rd crotchet in the R.H. The patent inaccuracy was corrected in GE, EE and FE4. In all sources a  was unnecessarily repeated before g1 in the chord in the L.H.

b. 240

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

..

Similarly as in bar 52, the bottom note of the 1st chord in FE1 (→FE2) is an erroneous a1. The patent mistake was corrected in FE3 (→FE4), EE and GE, which in the case of FE and EE could have been performed by Chopin.
