CLI has the erroneous cas the 8th semiquaver in bars 10 and 14. In bar 10 cwas initially printed also in FEcor, in which Chopin changed it to d3.

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

..

In bars 10 and 14 in one of the last proofreadings of FE (→GE,EE) cautionary naturals before c2 in the last triad in the bar were added. According to us, signs in these places are unjustified.

Lack of the  returning b2 on the last semiquaver in bars 10 and 14 is most probably an inaccuracy of notation of CLI. Chopin possibly wrote both signs already in the handwritten base for FE.
