b. 14

composition: Op. 28 No. 14, Prelude in E♭ minor

..

No sources except FC include accidentals before the 8th quaver in the bar; FC features  's restoring e-e1, written most probably in pencil. As was the case with a number of other similar additions, those accidentals were added by H. Scholtz, who introduced them also into the 1879 Peters edition he edited. An analogous change can also be found in many other subsequent editions of the Preludes. A possible oversight of the flats restoring e-e1 would not be unusual here, since similar mistakes are among the most frequently committed by Chopin; however, the very possibility of a mistake does not mean that the mistake was actually committed, particularly since there are no musical reasons to consider the version written in the sources to be erroneous.

In CLI and FEcor there is no  returning d3 on the 3rd beat of the bar. Chopin corrected his oversight in one of later proofreadings of FE (→GE,EE).

The  returning g, without a doubt omitted in A by mistake, was added in a proofreading of FE (→GE,EE).

composition: Op. 2, Variations, complete

The  restoring b1 in the 2nd half of the bar is absent in all sources. It must be Chopin's mistake, one of his most frequent errors.

b. 16

composition: Op. 29, Impromptu in A♭ major

..

In A (→GE1) and EE1 there is no natural restoring g on the last quaver. It is undoubtedly Chopin's oversight, one of his most frequent ones. The sign was added in GE2 (→GE3GE4) and EE2. It can be assumed that also the natural in FE was added during the proofing (it is absent in the analogous bar 98).
