b. 177

composition: Op. 49, Fantaisie in F minor

..

The bottom note of the minim chord in FE1 is provided with a  (D). The mistake was rectified in FE2 (→EE).

b. 184-186

composition: Op. 49, Fantaisie in F minor

E1 crotchet in b. 186 in A & GE2

No E1 crotchet in GE1

E1 crotchet in b. 184 in FE (→EE)

..

According to us, the most likely explanation for the difference in the placement of the E1 crotchet would be it having been added by Chopin both to A and [FC], although a Chopinesque correction to [FC] is also likely, not to mention a mistake by the copyist, misled by the similarity between the subsequent two-bar phrases. As it is impossible to determine whether Chopin considered one of the versions final, in the main text we give the text of the principal source (A), recommending the FE version as an equal variant.
The absence of E1 in GE1 most probably resulted from the engraver's distraction, who left space for this note while inserting , but eventually did not add it. This is not the only piece of evidence for the engraver's distraction in bar 186 – he also overlooked the first tie to B.

b. 185-187

composition: Op. 49, Fantaisie in F minor

..

There are no accidentals to the chords in the middle of bar 185 and 187 in A (→GE), which, when interpreted literally, results in E chords in both places, with g1 and g2, interfering with the E minor chords from the beginning of the bar, held with pedal. The overlooked flats were added – probably at Chopin's request – in bar 187 in FE1 (with a mistake – a  to e1 instead of to g1) and in bar 185 in FE2 (→EE), but not in GE.
In the main text we omit the  to the g2 quaver at the end of bar 187, unnecessary in the corrected version.

b. 185-186

composition: Op. 49, Fantaisie in F minor

..

The deletions visible in A in the 2nd half of bar 185 and at the beginning of bar 186 reveal that Chopin initially wrote the L.H. part an octave higher (in the treble clef, as it was 2 bars before). He committed a similar mistake in bar 197 as well.

composition: Op. 49, Fantaisie in F minor

In A there is no  to the 2nd quaver in bar 188 (g) and to the 3rd quaver in bar 189, at the same pitch. The patent inaccuracies were corrected in FE (→EE), while GE added only the latter.
