The notation of the last two quavers is inaccurate in the sources, since Chopin most probably considered the manner in which he wrote the chord on the 4th quaver of the bar – c
1-f
1-a1-e2-a2 – to be sufficient in order to mark the return to the main key of E major. Consequently, there is no accidental before the chord on the 5th quaver in FE (→EE,GE1→GE2), while the last quaver is lacking in the 
restoring B. On the other hand, all sources contain cautionary naturals before d2-d3 in the last R.H. chord, unnecessary if we assume that the preceding chord was interpreted correctly. A revision of this notation was performed only in GE3, and then incomplete, since it was only the restoring b that was added. In the main text we add both necessary flats (restoring b and B); we also add 3 cautionary accidentals – 
of g1 and the flats of b1-b2.
