In FC, the continuous slur written initially by the copyist, encompassing the last 5 bars, was divided into two slurs by Chopin between the 2nd and 3rd beats of this bar. We give this version, undoubtedly Chopinesque and present in the principal source, in the main text. On the other hand, the authenticity of the FE (→EE) version is uncertain, since one can easily imagine that the Chopinesque notation, either in [A] or in the proof copy of FE, could have been misinterpreted. Chopin could have, e.g. written the following, inaccurate slurs: , which in FE were interpreted in accordance with the tendency to adjust marks to regular rhythmic structures, e.g. bars, typical of engravers.
The crossed-out fragment of the initial, continuous slur visible in FC comes from the reviser of GE1, who thus clarified the slurring correction entered by Chopin.

slentando in FC (→GE)

smorz. - - in FE (→EE)

..

Chopin entered slentando into FC (→GE). Similarly, Chopin added the smorz. - - indication present in FE (→EE) probably only just while proofreading this edition.
Therefore, both indications, of a similar meaning, can be regarded as equal variants.
