FE (except for FE4) lacks in five necessary accidentals – naturals before d2 and b and sharps before f
, f2 and g2. This patent inaccuracy certainly has its source in the notation of [A]. Similarly in GC, in which, however, Chopin added a 
raising b
to b. In GC (→GE) there are also no naturals before the last octave in the R.H. – it can be an oversight of the copyist or a later addition in [A]. In the remaining sources the signs were completed (all additions can be attributed to a revision): three were added in EE1 and FE4, four in GE; only EE2 includes the correct notation. Cf. bar 24.
