In JC, there are a few accidentals, unjustified as cautionary accidentals: a 
before e1 at the beginning of the bar, a before bon the 4th quaver of the bar, a 
before the next a and a 
before f1 in the last chord. The first and last of those signs are also in PE. The same applies to bar 95, in those sources marked only as a repetition of bar 59.
