b. 108

composition: Op. 25 No 10, Etude in B minor

f1 in GC & GE1 (contextual interpretation), EE & GE2 (→GE3)

a1 in FE

FE has an aas the 3rd crotchet of the middle voice in the R.H. It is almost certainly the so-called Terzverschreibung error.
In GC (→GE1) the correct note is an f1. This patent error was corrected in GE2 (→GE3), EE also includes the correct version.

Octave in GC (→GE1)

Chord in FE, EE & GE2 (→GE3)

Lack of the middle note on the 3rd beat of the bar is almost certainly a mistake of GC (→GE1).
In FE the note is present, yet there is no  returning F. EE and GE2 (→GE3) have the correct text.

b. 113

composition: Op. 25 No 10, Etude in B minor

..

In GC (→GE1) and EE, there are no accidentals before the crotchets, so they should read as c and c2. In spite of the fact that the version does not raise any doubts as far as the sound is concerned, the omission of the naturals is proved by:

  • the logic of harmony – this and the previous triplet create an abbreviated version of the motif used in the progression in bars 109-112. In this abbreviated version it is then repeated twice in the further part of bars 113-114. There is no reason to resign from the semi-tone movement of crotchets filling the octaves in one place only;
  • misleading chromatic orthography – change from d to c despite preserving regular notation of the octaves in the F minor key;
  • signs added – probably by Chopin – in the proofreading of FE.

We add cautionary naturals before the d notes at the beginning of the bar after GE2 (→GE3).

b. 116

composition: Op. 25 No 10, Etude in B minor

..

There are no accidentals before the last octave in the R.H. in GC and EE1 (→EE2). Chopin added the overlooked naturals in the proofreading of FE, they are also in GE and EE3.
