Next to the bottom note of the 1st sixth in the 2nd half of the bar there is no accidental neither in A nor in GC and FE, which were proofread by Chopin. Therefore, we should accept this note to be d
1, and that is what we give in the main text, supplemented with a cautionary 
. However, it should be noted that Chopin would often forget to cancel an alteration, particularly when, just like here, they were present in another voice (cf., e.g. the Etude in A minor, Op. 10 No. 2, bar 1 and analog., in D
major, Op. 25 No. 8, bar 3, in G minor, Op. 25 No. 6, bar 4 or the Concerto in F minor, Op. 21, 3rd mov., bar 422 and analog.). In this situation, we cannot completely rule out the authenticity of the version with d1, in spite of the fact that Chopin, who almost certainly did not take part in the preparation of EE, could not have added the 
visible in that edition.
