..

In GC the part of the R.H. is written in this bar one octave lower, as the copyist forgot to end the octave sign in the new line of the text. All the remaining sources include the correct text.

GC (→GE)

FE1 (→FE2)

..

According to us, the first half of the bar has only one authentic version, written in [A] and conveyed by EE and FESch. The versions of GC and FE1, hence sources based on [A], were probably a result of its misinterpretation by the copyist and the engraver of FE. Chopin restored the correct text, by amending the mistake in FE2 and FESch and – most probably – in the base text to EE. The versions of FE3 and FE4 are most probably a result of mistakes at the time of proofreading FE2 and FE3 respectively.

4 slurs in GC

3 slurs in FE (→EE) & GE2

3 slurs in GE1

..

The notation of this bar is an example of Gutmann's carelessness, who would sometimes put other signs and slurs more or less accurately, without controlling their actual compatibility both with [A] and the music sense. The slurs were partially repeated in GE1 and corrected only in GE2.

At the beginning of the bar GC has a C1-E tenth. It is certainly a mistake, which is proved by, among others, the  before the bottom note, which does not make any sense before C1. All the remaining sources include an E1-E octave.

No slur in GC (→GE)

Slur in FE (→EE)

..

There are no reasons to doubt the authenticity of the slur of FE (→EE), although it is not certain whether it was overlooked in GC or added in [A] already after the copy had been prepared.
