..

In A Chopin did not restore the bass clef in this place, which renders the notation illogical until the end of the line in bar 270 (at the beginning of a new line, there is a bass clef). The mistake was corrected in GE (→FE,EE,IE).

..

EE1 has an a as the top note of the chord at the beginning of the bar. This is certainly a mistake, as indicated by the text of other sources, the awkward spelling without a cautionary , and a comparison with the analogous bar 68.
