b. 115

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

..

In GE, there is no crotchet rest for the lower voice on the last beat, which could be the engraver's oversight (see the complete record in bars 112-114) or a revision – GE omitted the corresponding rest also in the analogous bar 107.

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

In A there is no accidental before the penultimate semiquaver. The flat returning ewas added in the proofreading of GE1 (→FEEE, →GE2), perhaps on Chopin's demand. Moreover, a cautionary  was added before ein the L.H.

Continuous slur in A

2 slurs in GE

..

Division of the slur at the bar line is a typical arbitrary decision of GE (→FEEE), in this case justified by the not entirely clear notation of A at the transition between the pages.
