It seems that the second half of the R.H. in this bar was not printed in FE0. It may be a consequence of earlier rhythmic errors (see the previous note). The photocopy of FEG we have at our disposal does not let us state clearly which elements of the score were printed. Chopin certainly added a beam combining two quavers with a semiquaver, a semiquaver rest and a beam for the last semiquaver. Taking into account the rhythmic synchronisation of the hands, in FE0 could already have a quaver on the 2nd beat (misprinted in this place or possibly inaccurately added by Chopin in FEG) and the last semiquaver.
