FE and GE did not use the abridged notation of the 2nd and 4th beats of the bar applied in A (→FC); however, none of the accidentals was repeated on those beats in FE1, which resulted in a mistake in the 4th R.H. group – first, c3 was not raised to c
3, and then c3 was not restored. It was corrected in FE2 (→EE) by adding respective accidentals (the traces in some copies might be regarded as indicating that initially a 
was also added before e3). In turn, GE repeated all accidentals in both hands, which is not a mistake, but it unnecessarily makes the notation denser.
