In the last chord in bars 73 and 77 in the main text we change enharmonically d1 to c
1, considering Chopin proofreading of FE in bar 69 to be valid also in this place. EE1 erroneously swapped the accidentals in this chord (
was placed before d
1, whereas 
before e1). Actually, the sound of the resultant chord does not raise any doubts, yet the notation with the use of two superfluous accidentals is a proof of a patent mistake.
