As in bars 2 and 6, in A there are no accidentals to the last hemidemisemiquaver of the 2nd and 4th R.H. figures in bars 18 and 22, a 
(b2) and a 
(b
2), respectively. In AsI these accidentals are not necessary, since in the version of this manuscript, the aforementioned notes are absent. On the other hand, there is no to the 2nd note in the 2nd L.H. figure in bar 18 (b). In this context, the patent inaccuracies do not raise any doubts concerning the text.
