CLI has by mistake an on the 3rd beat of the bar. Probably it was similar also at the beginning of the bar, yet in this situation the copyist realised the mistake and corrected the erroneous note.

b. 9-13

composition: Op. 10 No 2, Etude in A minor

..

The naturals returning a1d2 and f2 in bars 9 and 13 are inaccurately written in some of the sources. In CLI they are totally absent, although in bar 13 the sign returning d2 is before the last semiquaver in the lower voice. In FEcor Chopin added them only in bar 9, yet, eventually, he also added the  returning f2 in bar 13 in FE (→EE2). In GE1 only the sign returning din bar 13 is missing. The remaining sources have the correct notation.

Triad & third/fifth in CLI

Triads in Ap & FE (→GE,EE)

..

The third on the 3rd beat in bar 10 in CLI was probably meant to be a fifth in the original version (Terzverschreibung). In the sources Chopin's hesitation concerning the placement of the cautionary  before cis also reflected.
