Issues : Authentic corrections of FE

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.

c3 in FE (→GE)

a2 in EE

..

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.

b. 103

composition: Op. 22, Polonaise

..

In EE the last semiquaver of the 1st beat of the bar is written down as F. In the penultimate stage of proofreading of FE (→GE), Chopin decided to change the notation to enharmonically equivalent G (traces of a correction performed in print are visible in FE).

b. 114

composition: Op. 22, Polonaise

..

EE1 is lacking in the cautionary  before a2. The accidental was added in the penultimate stage of proofreading of FE (→GE) and – probably on the basis of GE1 – in EE2.

Dotted rhythm in FE (→GE)

Quavers in EE

..

Two quavers in EE is the initial version, most probably authentic. In FE one can see that the dotted rhythm was introduced only just at the stage of proofreading.
