In GC and FE there is no  lowering a to a. The mistake was corrected in GE, EE also includes the correct text. The natural was also added in FED.

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.

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.
