b. 209-214

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

In the main text, we add cautionary flats before e's (in different octaves) at the end of these bars. These accidentals appear selectively in the sources – only in bar 214 in EE1, and in bars 210, 211 and 214 in GE and EE2.

a-c1-e1 in GC & FE (→EE)

a-e1 in GE

..

The absence of c1 in GE in the last crotchet is most probably the oversight by the engraver, influenced by similar figures in the preceding bars.
