b. 245-249

composition: Op. 49, Fantaisie in F minor

..

At the end of bar 245 and 249 in the main text we add a cautionary  to g3(2).

b. 246

composition: Op. 49, Fantaisie in F minor

..

In the 2nd half of the bar there are no accidentals in A and FE. Three flats overlooked by Chopin were being added in the remaining editions – in GE1 two were added, to g and g2, while in EE – to g2 and g1. The fully correct text is present only in GE2.

composition: Op. 49, Fantaisie in F minor

The 7th L.H. quaver in FE1 is a B instead of A. The mistake was corrected in FE2 (→EE).

b. 248

composition: Op. 49, Fantaisie in F minor

..

In A Chopin overlooked the  lowering g2 to g2 (yet he wrote a  to the next note!). The patent mistake was repeated only in FE1.

b1 & c2 in FE1

..

FE2 restored – perhaps at Chopin's request – the version of the bottom notes of the first two quavers as it was in A, which is an argument that the FE1 text is almost certainly a double mistake by the engraver.
