The bottom voice in the R.H. is written in A with a rhythmic error: 
. We assume that Chopin wrote a dot extending the f1 quaver by mistake ("in a flow" after a few other dotted rhythms in bars 201-202); afterwards, he noticed his mistake and left two quavers, expecting that the poorly visible dot would not mislead the engraver. The quavers correspond to the rhythm in the 1st violin part in Morch and they are compatible with a similar motif two bars earlier. The version of the editions, whose compliance with Chopin's intention cannot be entirely excluded, can be considered an alternative to the interpretation adopted in the main text.
