b. 186

composition: Op. 16, Rondo in E♭ major

..

We add a cautionary  before B​​​​​​​ in the main text. The accidental is present also in GE and EE3 (it must have been added due to the introduction of B on the last crotchet in the previous bar).

b. 186

composition: Op. 11, Concerto in E minor, Mvt III

..

In FE (→EE), the only accidental before the 1st chord of the 2nd half of the bar is a  before a, unnecessary in this context. In GE1 (→GE2), the accidental was moved to before f; however, a  lowering c​​​​​​​1 to c1 was not added. The latter was introduced only just in GE3.

b. 186

composition: Op. 16, Rondo in E♭ major

..

In the main text, we add a cautionary  before A​​​​​​​. Interestingly, a semiquaver later, the sources feature a cautionary  before a​​​​​​​3.

b. 186

composition: Op. 38, Ballade in F major

c2 in A (→GC,FE,EE)

c2 in GE1 (→GE2)

..

 lowering c2 to c2, added in GE1 (→GE2) in the middle of bar, presents the last of the arbitrary revisions resulting from complete misunderstanding of Chopin's sequence in bars 185-186. The accidental was removed in GE3.

b. 186-187

composition: Op. 22, Polonaise

..

From b. 186 to b. 219, the text of FE, encompassing pp. 17-18, is identical with b. 42-75 (pp. 9-10), since it was only two plates that were used to print these four pages in FE, out of which each was provided with double pagination.
