In the sources, a cautionary 
was repeated before the 2nd grace note in bar 186, which, according to us, is not necessary. In bar 190 in FE (→EE), there are no naturals before any of the grace notes, which the engraver of GE considered to be an inaccuracy requiring an intervention. In the main text, we suggest naturals before the first grace note in each of these bars.
