In FC (→GE) the first c2 note is a dotted crotchet. The mistake was probably provoked by the complicated layout of this bar, in which the d1-f1 third of the 2nd L.H. quaver is written on the top stave next to the c1-g1 fifth of the bottom R.H. voice, thus creating an illusion of a third quaver filling c2 of the top R.H. voice.

In FCI and A (→FE,FC→GE1) there is no  raising g to g in the 1st L.H. chord. The patent inaccuracy was corrected in EE and GE2 (→GE3).

A natural before the bottom note of the 1st bottom R.H. voice quaver (e1) is present only in EE, the only one in which this patent inadvertence of Chopin was corrected. Similarly, the  before the bottom note of the 2nd L.H. quaver (b), overlooked in A (→FE,FC→GE), was supplemented only in EE. As far as FCI is concerned, it is difficult to decipher the accidentals here based on the photocopy available to us – it seems that out of 3 necessary accidentals, the top one was overlooked, raising a1 to a1.

On the last quaver in A (→FC→GE1) there are no accidentals before the middle notes of the chords in both hands – a  before b1 and a  before d2. The patent inaccuracies were corrected in FE (only the ) and EE (both). In turn, in GE2 (→GE3) naturals were wrongly added before both notes.
(NB: both correct accidentals are present in FCI.)
