b. 263-265

composition: Op. 2, Variations, complete

..

In Af the L.H. rhythmic notation is more accurate in this entire fragment that starts here (until bar 267, the last one written in Af) – every half a bar, over each bass note, there is a quaver rest filling the top voice. The absence of those rests in A and the editions is a manifestation of the budding Chopinesque economy of notation, according to which rests the sole function of which is to fill the bar in one of the voices, are worth omitting for the sake of legibility if – as is the case here – it does not disrupt the understanding of the arrangement of voices and their rhythm. Cf. the note on bars 16-17 describing a situation in which a similar procedure turned out incomprehensible and misled the engravers.

b. 263

composition: Op. 49, Fantaisie in F minor

..

In FE1 the 1st quaver in the 2nd half of the bar is a d. The mistake was corrected – perhaps at Chopin's request – in FE2 (→EE).

In  GE1 b2 instead of c3 is mistakenly the upper note of the first dyad in the RH part.

b. 264

composition: Op. 35, Sonata in B♭ minor, Mvt II

Octave in GC (→GE)

Chord in FE (→EE)

The comparison with analogous motifs in a few places of Scherzo proves that the missing g2 note on the last crotchet is almost certainly a mistake of the copyist.
