According to us, the missing staccato dots over the chords in b. 766 and 768 are a result of inattention of the copyist and the engraver of FE. The dots do appear in A, yet their perception is hampered by other elements of notation bordering on them, i.e. a deletion (b. 766) and one of the dashes marking the range of the indication più mosso (b. 768).
