In A the 
to the 6th quaver in the bar is missing, which, in the face of the lack of an octave sign in the 1st half of the bar, does not impact the pitch of the note (a is present at the same pitch before a1, two notes earlier). Chopin also omitted the to the last quaver (a) and the 
to the bottom note of the 4th L.H. octave (F
). All the accidentals were added in GE (→FE,EE,IE).
