b. 158-161

composition: Op. 23, Ballade in G minor

..

Having returned to the key of E major at the beginning of b. 158, Chopin inserted and then deleted in A the naturals to a in this bar (in the right and left hands) and to a1 in b. 159. By contrast, he left the cautionary  to a2 in the R.H. in b. 161. This version was repeated by all editions. In the main text we add cautionary naturals to a1 in b. 159 and a2 in b. 160-161 and cautionary flats to the L.H. e1/2/3 notes in b. 158-161.

In A, the flats lowering a1 to a1 in b. 181 and 184-187 and a to a in b. 183 and 186-187 are missing. These patent inaccuracies were already corrected by FE (→GE,EE).

b. 228-229

composition: Op. 23, Ballade in G minor

..

The chromatic notation of A is inaccurate in a peculiar way – Chopin overlooked the  to the bottom note of the 1st octave in b. 228 (B1) and the accidentals to the bottom notes of the sixths on the 4th quaver in both bars (a2 and f2, respectively). It is also noteworthy that there is a cautionary  to f2, but not a quaver earlier to f1. FE added only a  to B1.
GE and EE added the remaining necessary accidentals to the version of FE, while GE also added cautionary naturals to f1 and f3. The former was also added by EE2 (→EE3), which results in a version adopted to the main text.
See also the notes in the next bar.
