composition: Op. 12, Variations in B♭ major

The last R.H. chord is devoid of accidentals, which results in c2-e()2-f2-a2. This is a patent mistake, as there is no doubt that it is a typical dominant seventh chord in B that should be used here. Both necessary naturals, to the outermost notes (c2 and a2), were added in GE, while in EE only the bottom one.
