b. 24-27

composition: Op. 26 No 1, Polonaise in C♯ minor

Continuous slur in A (→FEEE)

New slur from bar 27 in GE1

New slur from 2nd beat of bar 26 in GE2 (→GE3GE4GE5)

..

The phrasing slur at the transition to a new line between bars 26 and 27 was erroneously broken in GE1. In GE2 (→GE3GE4GE5) the moment of the slur's division was moved two crotchets earlier. Although such a division of the slur is pianistically justified, it was deleted by Chopin in A (one can see a connection of the slurs in this place).

b. 27

composition: Op. 26 No 1, Polonaise in C♯ minor

Quaver b in the sources

Crotchet suggested by the editors

..

We add a crotchet stem for b1. The absence of correction in FE can be considered to be Chopin's oversight or the engraver's inaccuracy in the interpretation of correction.

b. 29

composition: Op. 26 No 1, Polonaise in C♯ minor

Minim & crotchet in FE (→GE,EE)

Dotted minim in A

..

The g1 dotted minim present in A in the top voice of the L.H. is the original version – Chopin changed it in the proofreading of FE1 to an a1 minim and a g1 crotchet.
