A does not have any accidentals in this bar – see the adjacent note. In a proofreading of FE (→EE,GE1→GE2) cautionary flats before a
1 and a2 on the 2nd quaver in the bar and before e1 on the 9th quaver (the latter is probably a mistake and we omit it in the main text) were added. In GE3 (→GE4) a 
was added before f3 on the 2nd quaver in the R.H., yet also a instead of a was inserted in the L.H. (a1 instead of a1).
