The sources differ slightly, as far as the position of smorzando is concerned. In EE the indication was erroneously specified as Amorzando.

In EE, starting from the 2nd triplet, there are no stems sustaining the sound of the last notes of particular triplets. Most probably, it is a mistake (cf. bar 28).

The sources differ in the number of accents in the L.H. in bars 29-30. In A, GE2, GE3, EE the accents are in bar 29 over the 5th and 11th quaver (f1) and in bar 30 – over the 5th quaver (e1). In GE1 and GE4 there is only an accent in bar 30 over the 5th quaver (e1). In FE there are no accents at all.

A, FE and EE are lacking the natural next to the 10th quaver in the L.H. The sign was added in GE. The lack of the sign must be considered as an error, as ‒ despite the fact that is has only a cautionary character ‒ it appears in A in all analogous 5 bars (27-28 and 109-111).
