  b. 33

C-c in A (→FCGE1, →FEEE)

E-c in FED, FEJ, FES & GE2 (→GE3)

The published version of the last L.H. crotchet, a C-c octave, is most probably a result of a correction, which is revealed by the way it was written down in A – the bottom note is at the same pitch as the three E notes in b. 32-34 (as well as the ledger lines of the three D notes), while the ledger line placed above it differs in the thickness from the adjacent ones, which shows that it was added later. Therefore, it was initially an E-c sixth. In this situation, we consider the correction (performed in all three teaching copies bearing traces of being developed, i.e. FED, FEJ and FES) turning the octave back to a sixth to be Chopin's final decision (probably), presumably taken after multiple trials.
The fact that GE2 includes the version passed by Chopin to his pupils might indicate that the publisher had contact with a person from Chopin's circle, someone who knew about that correction – it seems rather unlikely that the reviser introduced such a change without any source indications. However, the octave was perhaps deemed mistaken because in this entire phrase, all the remaining c notes of the upper voice are coupled with an in the lower one.
A similar situation can be found in b. 49.
