In A the sign above the 4th quaver in the L.H. is deleted - it is probably an accent, although it could also have been the head of c1.

Our suggestion

..

In the main text we give the title and dedication in accordance with the title page of the entire opus in A (we develop the Mme and Csse abbreviations used in A) and FE. In A (→GE) and FE, the particular etudes are provided with an additional title, Etude, with a corresponding ordinal number, which we represent through the number preceding the score. In EE, the numbering includes 12 Etudes, Op. 10, hence this etude is No. 13.
In GE and EE, the title includes the number of etudes in the entire Op. 25, which could be related to the division of the entire opus into two books, 6 etudes each, performed in these editions. Nothing indicates that Chopin considered this information to be important, although in other opuses including groups of pieces (MazurkasNocturnesPolonaisesPreludesWaltzes), he would generally give the number of pieces.
EE2 omits the dedication, as the individual title page was replaced with a collective one, common for all Chopin pieces published by Wessel; in EE3, the dedication was added above the score on the 1st page.

Long accent in AI

  in FE

  in GE2 (→GE3)

..

The long accent under f2 at the beginning of bar 2 in #AW is the original concept of dynamic markings in these bars. In A one can see that Chopin rejected the accent (placed above this note) in favour of a pair of   hairpins. The hairpins were incorrectly reproduced in GE1 (→GE1a), yet only the fact of beginning diminuendo in GE2 (→GE3) from the beginning of bar 2 may be considered as a quite significant change. In FE and EE, diminuendo immediately follows crescendo. In the main text we reproduce the signs of A, the only ones written undoubtedly by Chopin's hand.
