IE added 4 short 
marks, indicating long accents, as in GE (→FE,EE,IE) in the next bar – see the respective note. According to us, they could have resulted from a mistake – the engraver inserted the marks a bar too early; having realised his mistake, he assumed that the marks did not need to be removed, as they did not disturb the musical course, and he limited his self-corrections to adding the four right marks to bar 233.
