A, FE, EE lack the flat restoring e2 at the end of the bar. The accidental was added in GE. Omissions of such type belong to the most frequently committed mistakes by Chopin. Cf. bar 71.

In A (→GE1) and EE1 there is no natural restoring g on the last quaver. It is undoubtedly Chopin's oversight, one of his most frequent ones. The sign was added in GE2 (→GE3GE4) and EE2. It can be assumed that also the natural in FE was added during the proofing (it is absent in the analogous bar 98).

On the 8th quaver in A, FE and EE1 there is no natural reinstating f1. Chopin corrected his mistake in FEJ and FES. The sign was also added in GE and EE2.

We add the accidentals returning f2 and e2 on the 10th and 12th notes in the R.H., which were omitted in A, FE and EE. The additions were already made in GE (in GE1 only the natural next to f2) and EE2. It is a typical error of Chopin.

AFE and EE are lacking the flat returning e2 at the end of the bar. This type of oversights are the most frequent errors made by Chopin. Cf. bar 71.
