In A (→FC,FE) accidentals were inserted very inaccurately – in total, 4 sharps and 12 naturals are missing – which, however, does not impede the determination of the correct text. Accidentals were being added in GE and EE, although it is only in EE2 that the notation is totally correct. The naturals before the b-b1 octave in b. 44 were also added in FED.
Interestingly enough, the notation of FCI is more accurate than the one of A – only one 
and 5 naturals are missing.
