b. 40

composition: Op. 10 No 11, Etude in E♭ major

..

Before the last chord in A there are no naturals returning c2 and c3. The accidentals were probably added only in the last proofreading of FE (→EE), as they are not included in GE1 (they were added in subsequent GE,s).

composition: Op. 10 No 11, Etude in E♭ major

In the last proofreading of FE (→EE) a cautionary  before was added before the 4th chord (the accidental is absent both in A and GE). We add naturals before d1 and d2 in the 2nd chord instead.
