In the main text we omit the cautionary  to a, present in all sources, which is totally unjustified here.

b. 187-195

composition: (Op. 4), Sonata in C minor, Mvt IV

..

In A in the ascending passages in bar 187, 193 and 195, Chopin wrote accidentals only in the first half of each of the bars. All the necessary accidentals further on in the passages were added in GE (→FE,EE,IE).

b. 188

composition: (Op. 4), Sonata in C minor, Mvt IV

As in bar 5, in A the  restoring B (the bottom note of the chord in the middle of the bar) is missing. Chopin's patent mistake in this harmonic context was corrected in GE (→FE,EE,IE).

As in bar 7, in the 2nd half of the bar A does not include any accidentals, while the sharps raising all f notes (in various octaves) to f present in GE (→FE,EE,IE) were arbitrarily added during the revision of GE. In the main text we provide the A version, adding only a cautionary  to the first of the discussed notes (f2).
