b. 278-279

composition: Op. 39, Scherzo in C♯ minor

New slur in EE and GC

One slur in FE and GE

..

Both versions of the slurring may be authentic, and the version of FE is probably later. However, the fact that GE - the source that was, after all, based on GC - has a continuous slur shows how easy it was for the engraver of FE to misread the manuscript. Bearing that in mind, we take the slurs of EE and GC as our main text. The practical difference in performance is very slight anyway.

b. 278

composition: Op. 39, Scherzo in C♯ minor

..

In GC, this bar is marked as the repetition of the previous one, which must reflect the notation of the autograph.

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.
