b. 47-49

composition: Op. 10 No 4, Etude in C♯ minor

..

In AI Chopin wrote the 12th semiquaver in bars 47-48 (and in bar 49, marked as repetition of bar 48) as f1. In FE (→GE,EE) the note is written as g1, as a result of which the next note has to be provided with a .

b. 50

composition: Op. 10 No 4, Etude in C♯ minor

..

In the last group of semiquavers, in the place where FE (→GE,EE) has a b1, in AI there is a c2. By introducing this clearly justified correction, Chopin did not check its result precisely – in FE (→GE1GE1a,EE) there is no  before c2, still necessary despite the change of the previous note from c2 to  b1. This patent oversight was corrected in GE2 (→GE3GE4GE5).

b. 54-56

composition: Op. 28 No. 17, Prelude in A♭ major

..

In these bars the version of FCI clearly deviates from the final one – different harmonic rhythm in b. 54 and different shape of the melody in b. 55-56. We can also observe small changes to the arrangement of chords and enharmonic notation.
