The notation of accidentals is inaccurate in the majority of the sources, which, however, does not cause any difficulties in the interpretation of the text. In the 2nd half of the bar, GC and FE have only one sign: a 
before the last chord in the R.H., whereas in FE it restores f2, while in GC – probably erroneously – it raises g
2 to g2. GE added to the written in GC another one, raising b2 to b2. Only EE includes all necessary signs. Moreover, all sources include a superfluous before d1 in the 3rd crotchet in the L.H. In the main text, we omit this sign, in turn, we add a cautionary before f3 (in the last chord).
