b. 17

composition: Op. 26 No 2, Polonaise in E♭ minor

Crotchets in A

Quavers in FE (→GE,EE)

..

We give the stems extending the sound of the 2nd and 4th quavers in the L.H. after A. All editions omitted them here, in bar 18 and in all their subsequent repetitions, probably due to the engraver's misunderstandig Chopin's notation.

b. 18

composition: Op. 26 No 2, Polonaise in E♭ minor

..

A has no  lowering d1 to d1 on the 3rd beat. The undoubted Chopin's mistake was corrected already in FE1, possibly at his direction.
