The 4th page of A (bars 50-65) is less carefully written; in fact only two octaves in the R.H. (also among these being a part of the chords), requiring cautionary accidentals, are correctly written (the octave in bar 50 and the chord at the beginning of bar 55). The remaining 13 either do not have any accidentals (bars 55 and 65, discussed separately) or they have an accidental only next to one of the notes. In the editions all these patent oversights were completed.
