The natural raising a1 to a1 in bar 7 and the  returning d1 in bar 8, omitted in A, were added in a proofreading of FE (→GE,EE).

b. 7-8

composition: Op. 25 No 8, Etude in D♭ major

..

In A, FE and EE1 there is no cancellation of a few previously raised notes in chromatic passages:

  • in A and FE there is no  returning f2 at the end of bar 7 and two flats in bar 8 – returning a2 in the 8th sixth and e3 in the 10th sixth;
  • EE is missing the above three and flats returning g2 in the 10th sixth and d3 in the 12th sixth in bar 8.

The remaining editions introduced additions to these patent oversights (some of all):

  • GE1 added the  returning a2 in the 8th sixth in bar 8, while GE2 (→GE3) also the rest of the overlooked signs;
  • EE2 (→EE3) added the flats returning a2 in the 8th sixth, g2 in the 10th sixth and d3 in the 12th sixth in bar 8, which resulted in the same text as in GE1.

b. 7

composition: Op. 28 No. 8, Prelude in F♯ minor

..

There are no accidentals before the last pair of demisemiquavers in A. Therefore, they should be interpreted as c2 and c3 (the  before the 5th demisemiquaver of the bar is in force), which is, of course, impossible. In this Prelude Chopin took it for granted that the second and last demisemiquavers in each group are an octave higher than the preceding melodic note, thus he marked precisely only the pitch of the melodic notes (cf. b. 1-4). Therefore, there are no doubts that it is the bottom note that is written correctly, c2, and the inaccuracy concerns the top note, which must be a c3. Interestingly enough, the absence of a  restoring c3 was not noticed in any of the remaining sources, even in GE2, in which a cautionary  was added before c2.

In CLI there is no  returning don the 5th semiquaver in the upper voice. It must be a mistake.

b. 8

composition: Op. 10 No 6, Etude in E♭ minor

..

In A there is no  returning don the penultimate semiquaver in the R.H. The natural next to the subsequent note proves that Chopin forgot about the existence of d1 at the beginning of the bar. The sign was added in a proofreading of FE (→GE,EE).
