The missing   marks are one of a few patent oversights of Fontana – cf., e.g. b. 4-7.

e1 in GE

As was the case with b. 5, the version of GE is most probably a mistake of the engraver.

b. 25

composition: Op. 28 No. 24, Prelude in D minor

..

In A there are no naturals raising b to b. The patent inaccuracy was corrected in FC (→GE) by adding a  only before the grace note, while in FE (→EE) in the way adopted in the main text.

b. 26-42

composition: Op. 28 No. 24, Prelude in D minor

..

In b. 26, 27 and 40, the L.H. part in A (→FC) is marked with / as repetition of the preceding bar. Abridged notation is used in the manuscripts also to mark the 2nd half of the bar in b. 29-37, 39 and 41-42. Out of the editions, in was only FE that used a similar notation, although to a lesser extent – in all the aforementioned bars, their second halves were marked with a / mark.

b. 26

composition: Op. 28 No. 24, Prelude in D minor

..

The crossings-out visible in A reveal that the initial motif of this phrase (from c1 to b1) was initially provided with shorter slurs, adjusted to the earlier rhythmic version. The a1 quaver and the c2 semiquaver were separated by a semiquaver rest (as it is in b. 8), and the slurs encompassed three notes before the rest and two after the rest.
