In the main text, we add a cautionary 
before the 8th semiquaver, b1. The mark was added both in GE and EE; in both editions, a 
lowering this note to b
1 was initially added. In EE, this routine revision, unsuitable in this context, was detected still before EE1 had been published (probably thanks to Fontana), whereas in GE, the mistake was corrected only just in GE2 (→GE3).
