In A there is no 
raising d
1 to d1 on the 4th quaver in bar 313, whereas the signs in bar 314 were added with pencil. In spite of the obvious accuracy of these additions, their authenticity is not certain, since other additions made with pencil in A were added rather by a foreign hand – cf. bar 256 and 310. All sources include a raising d1 to d1 in the last quaver in bar 313. We omit this sign in the main text, since after the oversight on the 4th quaver had been corrected, it became superfluous.
