b. 14

composition: Op. 26 No 2, Polonaise in E♭ minor

..

There are no naturals rising a and d1 to a and d1 in A. Chopin's mistake resulted supposedly from a hasty correction—the composer initially marked the L.H. part in this bar as a repetition of the previous bar, and only after having spotted the diffrence on the 2. quavers of both bars wrote it out in full. The accidentals were added in FE1 and all the subsequent editions.

b. 15

composition: Op. 26 No 2, Polonaise in E♭ minor

..

A (→FEEE1) has no  rising g1 to g1 on 4th L.H. quaver. The obvious oversight was corrected in GE and EE2. Similarly in bars 63, 119 and 167.

b. 16-17

composition: Op. 26 No 2, Polonaise in E♭ minor

..

In the main text we omit the cautionary flats, present in the sources, next to c3 in the R.H. (in A in bar 17 before both notes; similarly in bar 18). It is an obvious example of Chopin's insecurity concerning the issue of presence of particular accidentals in the key signature. Cf. the note on c2 in the L.H. in bar 17.
