b. 8

composition: Op. 25 No 4, Etude in A minor

..

In EE there is no  returning f2 (despite the presence of – as in the remaining sources – cautionary  before g2). It is most probably an oversight of the engraver or copyist performing the base text to EE.

b. 26

composition: Op. 25 No 4, Etude in A minor

..

The cautionary  before d2 at the end of bar 26 is in all sources. A respective sign in the L.H. was added only in GE and EE2 (→EE3).
