In JC, there are a few accidentals, unjustified as cautionary accidentals: a  before eat the beginning of the bar, a  before bon the 4th quaver of the bar, a  before the next and a  before fin 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.
