b. 37

composition: Op. 35, Sonata in B♭ minor, Mvt I

Minim without dot in GC (→GE1)

Dotted minim in FE (→ EE) and GE2

..

This is probably the copyist's omission, repeated in GE1 and corrected in GE2.

b. 39

composition: Op. 25 No 11, Etude in A minor

No fingering digit in GC (→GE)

'1' in FE & EE

..

Lack of the fingering numeral over the 6th semiquaver in GC (→GE) is a result of a patent oversight of the copyist.

b. 39

composition: Op. 25 No 11, Etude in A minor

..

There is no accidental before the penultimate semiquaver in GC (→GE1), FE and EE. The missing  returning d3 is undoubtedly an oversight of Chopin, corrected in GE2 (→GE3).

b. 40

composition: Op. 25 No 3, Etude in F major

..

In GC, FE and EE1, there are no naturals before the 1st semiquaver and 2nd quaver in the R.H. (g1 and d2). Both patent inaccuracies were corrected in GE, whereas in EE2 (→EE3) and FES, only the first of the signs was added, the  lowering g1 to g1.

b. 40-41

composition: Op. 35, Sonata in B♭ minor, Mvt II

No accidentals in GC & FE1 (→FE2EE1)

Naturals in GE, FE3 (→FE4) & EE2

..

The absence of accidentals on the 2nd and 3rd beat of bar 40 and 2nd beat of bar 41 in GC and FE1 (→FE2EE1) is almost certainly Chopin's mistake. It is confirmed by naturals raising g1 to g1 in bar 40 and g to g in bar 41, added in the most probably authentic proofreading of FE3 (completed with the last missing  in FE4). Similarly in bars 228-229.
