b. 218-219
In both bars in FE0 (→FE,FEG) there is not any lowering g3(2) to g3(2). The flats in bars 217 and 220 prove Chopin's oversights, probably still in [A]. Some of the necessary signs were added in pencil by the composer in FED (both before g3) and in FEJ (at the beginning of bar 219). They were also added in GE and EE (the sign in bar 218 only in GE2 and GE3).
