b. 264

composition: Op. 49, Fantaisie in F minor

..

The cautionary  to c2 was added – perhaps at Chopin's request – at the stage of proofreading FE1 (→FE2EE).

b. 265

composition: Op. 49, Fantaisie in F minor

..

In A there are visible traces of corrections to the R.H. triplet. Chopin initially wrote it half a tone lower, as in three analogous bar 94, 98 and 261. A side effect of the correction could have been an oversight of the  restoring g2 in the 2nd half of the bar – in the initial version of this triplet the accidental was not necessary (see note next to this minim).

b. 265

composition: Op. 49, Fantaisie in F minor

..

In A (→GE) there is no  restoring g2 in the middle of the bar. Chopin's patent oversight was corrected in FE (→EE), which could have been done by Chopin himself in [FC] or while proofreading FE1.

Chord with a2 in A (→GE)

Octave in FE (→EE)

..

The absence of a2 in FE (→EE) probably resulted from the inaccurate [FC] notation – notes written down as dots, as it was performed by both Chopin and Fontana, were sometimes very poorly visible at the intersection of a stem and a ledger line.

In EE2 a cautionary  was added to e2 in the last quaver.
