In CLI and Ap the 7th and 15th semiquavers are written as a1. At the same time, the notation of Ap is faultless, whereas in CLI there is no  returning a1 on the 4th beat of the bar. The latter also appears in FEcor, in which Chopin added the , yet only before the last note. It was moved to the correct position only in a later proofreading of FE (→EE2→EE3), which, eventually, displays an entirely correct text.
In GE and EE4 further revisions concerning this section (from the 7th semiquaver to the end of the bar) were performed, adding or removing cautionary accidentals. The modifications do not change the meaning of the text, they only influence its transparency.

The traces of a  visible in the L.H. part in A1 at the beginning of the bar show that Chopin started writing d here, yet he realised it quickly and wrote c.

Our suggestion based on FE

g1 & f1 in GE & EE4
..

In A the last note in the 1st half of bar 32 is f1, after which three naturals follow: before f2 in the next chord and before f1 at the end of this and next bars. In a proofreading of FE (→GE,EE) Chopin changed f1 to g1 and deleted the already unnecessary  before f2. In FE (→EE2→EE3) the accidental before the last note in bar 32 was also removed, however, the remaining traces suggest that it was a  and not a . The assumption is confirmed by f1 appearing in this place in GE (and EE4). In the main text we give the undoubtedly final notation of FE.

composition: Op. 10 No 7, Etude in C major

e1 in A

d1 in FE (→GE,EE)
..

While proofreading FE (→GE,EE), Chopin changed the notation of the bottom note of the 5th and 6th semiquavers from e1 to d1. At the same time, he did not realise that after the change, a  returning d1 in the last pair of semiquavers should be added. The mistake was corrected in GE and EE4.
