b. 34-36

composition: Op. 26 No 2, Polonaise in E♭ minor

..

A has no  rising c1 to c1 in bars 34 and 36. The obvious inaccuracy of Chopin's notation was corrected in FE (→GE1) in bar 36, and in the remaining editions in both bars.

Instances of omitted essential naturals next to notes C in different octaves occur in A repeatedly in the whole section (bars 33-40).

b. 35

composition: Op. 26 No 2, Polonaise in E♭ minor

A has no  rising c to c. The gap was filled in already in FE1. In all sources a  is superfluously repeated next to the demisemiquaver c2; A and EE also have  next to c1 at the end of the arpeggio.
