b. 265-269

composition: (Op. 4), Sonata in C minor, Mvt IV

..

In A there is not a single  to the bottom note of the octaves (D) in these bars (as well as in the next ones, until bar 274). The patent inaccuracy was corrected in GE (→FE,EE,IE).

b. 265

composition: (Op. 4), Sonata in C minor, Mvt IV

..

In A Chopin did not restore the bass clef in this place, which renders the notation illogical until the end of the line in bar 270 (at the beginning of a new line, there is a bass clef). The mistake was corrected in GE (→FE,EE,IE).

in A

 in GE (→FE,EE,IE)

..

The  mark seems absolutely clear in A; however, the engraver could have been confused by the delicate trace of the first, failed attempt to write it – it was only the second time that there was enough ink for an entire mark.

b. 266

composition: Op. 39, Scherzo in C♯ minor

No sign in EE

Arpeggio in GC (→GE) & FE

..

The absence of the arpeggio wavy line in EE is probably an error, yet we cannot rule out the possibility that this was the initial version of the notation here.

Pedalling in EE and FE

No markings in GC (→GE)

..

GC (→GE) has no pedal marks in this bar. This is almost certainly the mistake of the copyist (see also notes to bars 260-265 and 265-266).
