No sign in A (→GE)

Pause in FE (→EE)

..

The fermata was added probably by Chopin in the proofreading of FE (→EE). The composer probably paid attention to the clumsy layout of the text, in which the group of small quavers starts directly after the ccrotchet.

2 times  in EE

..

The  signs, present in bars 151 and 153 in A (→GE), are the original version of notation of these ornaments. In analogous bars 155 and 157, Chopin already used mordents; what is more, in the proofreading of FE he changed  to  also in bar 151 (most probably he wanted to do it in bar 153 too, yet the engraver of FE must have deleted , but forgot to insert ). EE repeated  after FE in bar 151 and added  – by analogy – in bar 153.
