b. 636

composition: Op. 11, Concerto in E minor, Mvt I

..

A sharp raising c2 to c​​​​​​​2 appears in FE (→GE1GE2,→EE1EE2) only just before the 4th quaver of the bottom voice. Chopin would write an accidental too late on a few occasions (e.g. in the Etude in F Major, Op. 10 No. 8, bar 43). An accidental at the beginning of the bar was added in EE3 and GE3, yet it was only GE3 that removed the  in the middle of the bar, unnecessary in this situation.

Slurs in FE (→EE)

Slurs in GE

..

The slurs of FE (→EE) are probably inaccurate, since it is difficult to find a reason that would justify their different range – cf. bars 621-629 and the remaining ones in this fragment. However, it has to be said that if it were not for the ratio of the number of one type of the slurs to the other, it would be the slurs of FE, encompassing the entire motifs, that could be considered to be more accurate.

b. 636

composition: Op. 31, Scherzo in B♭ minor

in A (→FEEE)

No sign in FC (→GE)

..

In both manuscripts, this bar is a literal repetition of b. 185 (it is not written out in full), and like there, the oversight of a  sign in FC resulted in GE lacking it.
