Same as in analogous bar 16, in FEcor Chopin changed the crotchets in the L.H. to quavers separated with rests. The crotchets, being undoubtedly the original version, also appear in CLI (with erroneously written semiquaver flags next to the 2nd crotchet) and Ap.

In CLI there are no naturals returning c2 and e2, nor the sharp raising g1 to g1. The second of these mistakes – lack of the  before e2 – remained unnoticed also in FEcor.

In CLI there are no naturals returning a1 and d2 in bar 45 and a2 and d3 in bar 46. These patent errors were corrected by Chopin in FEcor. The accidentals – apart from the first one – were overlooked in EE2.

The version of CLI seems to be the earliest shaping stage of the part of the L.H. in the ending of the Etude. However, it cannot be excluded that the notation is incomplete (lack of ties) or erroneous (one-voice notation of bar 47). After considering all possible mistakes and oversights, the version of CLI does not differ from the version of Ap. In any case, Chopin waived dividing the octave in bar 47 already in the base text for FE, which we consider as the final decision.
