The slur of A is most probably unfinished due to ink flow problems; however, it is unclear where it should end. Two possibilities are involved: the beginning of b. 723, which is supported by the slurs in the analogous situations in b. 718-719, 758-759 and 762-763, or the end of b. 722, as it was interpreted by the copyist and which is indicated by the bend of the right-hand ending of the slur (or its visible, written part). In the main text we adopt the former, yet we consider the latter to be equivalent.
