b. 179

composition: Op. 12, Variations in B♭ major

..

In FE the  raising c4 to c4 was overlooked, which was noticed and supplemented both in GE and EE.

b. 179

composition: Op. 12, Variations in B♭ major

Wedge in FE

No mark in GE

Staccato dot in EE

..

It seems that the aim of the EE reviser's intervention could have been the standardisation of marks in both parts of hands – the L.H. chord is provided with a dot, as the preceding ones, which makes this mark more reliable than the single wedge in the R.H. in this fragment. However, in the main text we keep the FE markings, as the use of different marks in the parts of both hands can be easily explained by the textural context – the L.H. chord continues the current course, while the R.H. octave does not.
The absence of the mark in GE is most probably an oversight.

b. 181

composition: Op. 12, Variations in B♭ major

..

In the main text we omit the cautionary  to a2, present in all sources. At this stage of this regular progression, an accidental seems superfluous.

..

In the main text we put a reminder  next to e3, as it was done in GE.
