b. 57

composition: Op. 22, Polonaise

..

In the main text we add a  before e2, the 10th note from the end of the bar. Due to the previous  before e3, this accidental was sometimes considered superfluous – it is absent in FE (→GE1) – yet it was added in EE and GE2 (→GE3). Moreover, we add a cautionary  before b2 by the end of the run.

b. 57

composition: Op. 22, Polonaise

..

The sources are lacking in the accidental before the 2nd played note of the run. It must be Chopin's mistake (one of the most frequent ones – oversight of an alteration's cancellation), since a2 would have suggested a turn towards B major (G minor), and not F minor, whose dominant we are about to hear. Due to the absence of this accidental, a2 should also be in the ending of the run.

b. 59-60

composition: Op. 22, Polonaise

..

EE1 is lacking in the accidentals before the last semiquaver in b. 59 and the 4th note of the quintuplet in b. 60. These are patent mistakes – cf. the  lowering d2 to d2 in analogous b. 21 – probably committed still in [A], from which they got into EE1 through a proof copy of FE. In the very FE (→GE) Chopin not only added both flats in the last stage of proofreading, but also a cautionary  before d3 at the end of b. 60. All 3 accidentals were also added in EE2.
The same in b. 203-204.

b. 61

composition: Op. 22, Polonaise

..

FE (→GE,EE) are lacking in the  restoring d2 on the 6th note of the run. In EE it is also the  restoring e2 two notes later that is missing. In practice, these mistakes are of no major significance, since there is no doubt that we are dealing with a chromatic sequence. See also b. 205.

The version of EE is most probably the original version adopted from FE (or merely a Terzverschreibung), corrected in the very FE (→GE) in the last stage of proofreading. The same in b. 206.
