In A (→FC,FE) in this bar Chopin inserted cautionary accidentals only before the first notes in both hands – d and b
2. In the main text we also add accidentals before the 2nd quaver and the 2nd beat of the bar. Some of them were already added in EE1 (flats before b-b1 on the 2nd quaver and before e) and in GE and EE2 (the same as in EE1 as well as a 
before a1 and a 
before f2). Moreover, GE and EE2 added a before e2.
All the aforementioned accidentals in the bottom R.H. voice – before a1, before f2 and before e2 – as well as a before e are also to be found in FCI.
