in GC and FE

in EE

in GE

..

Lack of the cresc. indication in EE is most probably an error (see the note to bar 275). Lack of the dashes delimiting the cresc. scope in GE is an error beyond any doubt.

b. 278

composition: Op. 21, Concerto in F minor, Mvt I

..

In A there is no  restoring a. This patent mistake – cf. analogous bar 130 – remained unnoticed by Chopin both during the proofreading and lessons. Revisers of the editions also did not notice it.

b. 279

composition: Op. 39, Scherzo in C♯ minor

No sign in EE & GC (→GE)

 in FE

..

The  mark, appearing only in FE, seems very much in place from the musical point of view. This is also the only version that is definitely authentic, as the absence of that mark in GC (→GE) may be accidental, and in EE it is almost certainly so (cf. bar 275).

b. 280-282

composition: Op. 39, Scherzo in C♯ minor

No sign in EE

 in GC (→GE) & FE

..

In EE,  the  mark was either omitted (see the note to bar 275), or misread as a L.H. slur.

b. 281

composition: Op. 39, Scherzo in C♯ minor

..

EE does not have the treble clef in this bar, which is an obvious error. The correct clef in placed in bar 283 that opens a new line of text.
