b. 24

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

..

In A there is no  before the topmost note. It is a result of an oversight in the change of notation of this chord from f1-c1-f2 to e1-c2-e2. The accidental was already added in FE (→GE,EE).

Our variant suggestion

..

Same as in bars 1-14, the omission of the hairpins in bars 25-26 and 28 in the editions may be – independently from the reason – considered as accepted by Chopin. Also in this case the musical image with only one pair of marks in bar 27 is logical and convincing. In the main text we give additional marks of A in brackets, which, according to us, will offer the performer the richest palette of performance possibilities.

The wedge visible in A over the 1st chord in the R.H. was omitted in FE. In the remaining sources a dot was added here.

The sources differ in the combination of cautionary accidentals used in this bar. A (→FE) has a  before d1 in the 1st chord and a  before e1 on the 5th quaver in the bar. In GE the  was omitted, while in EE – the . Moreover, in GE2 (→GE3GE4) and EE4 was added before a1 on the 2nd quaver. In the main text we also add a  before g2 on the 5th quaver.

b. 25

d1 in A (→FEGE)

c1 in EE

..

The change of d1 to c1 in the chord on the 3rd quaver in the bar introduced in EE (there are visible traces of correction in print) is certainly an arbitrary change of the reviser who, presumably, followed the analogy from bars 27 and 29.
