  b. 48-52

In the autographs there are no sharps returning f1 and f3 at the 6th semiquaver in bar 49. From the harmonic point of view, f1 and f3 could be possible here, yet taking into account the regularity of the figuration's structure, one can assume this omission as a clear oversight. The signs were added – probably by Chopin – in a proofreading of FE (→GE,EE; in GE1 and GE1a there is no  in the L.H.).

In bars 48-52, AI still lacks several accidentals, yet due to the octave doublings between the parts of both hands, it does not lead to any text doubts.
In GE1, before the top note of the 5th semiquaver in the R.H. in bar 49 there is an erroneous  instead of . The error was also in the proofreading copies of FE1, yet it was corrected in the last proofreading.
In FE1 (→GE1,EE2EE3) there is no  lowering f3 to f3 in the 5th semiquaver in bar 51.
