b. 142

composition: Op. 22, Polonaise

..

There are no accidentals before the 4th and 8th semiquavers in FE (→EE,GE). The natural put before c4, the last note in the bar, proves that Chopin considered the  from before the 1st quaver of the bar to be valid up until this place, thus regarding the aforementioned notes as c2 and c3 (cf. a similar situation in b. 144). In accordance with the contemporary rules of chromatic orthography, we provide the discussed notes with sharps.
