b. 74-76

composition: (Op. 4), Sonata in C minor, Mvt II

..

In A there is only one  to the d2-d3 octave, both in bar 74 and 76. The missing accidentals were added in GE (→FE,EE,IE).

b. 75-76

composition: (Op. 4), Sonata in C minor, Mvt II

Slur to d in A, literal reading 

No slur in GE (→FE,EE,IE)

Slur to B suggested by the editors

..

When interpreted literally, the A slur must be inaccurate – unfinished – as many other slurs in this manuscripts (cf., e.g. mov. I, bars 182-183 or mov. IV, bars 350-351). At the same time, it does not matter whether we regard it as reaching d or c. Therefore, one can understand why the GE engraver did not include this slur (unless it was a mere oversight). In the main text we suggest a slur modelled after analogous bars 73-74.

b. 76

composition: (Op. 4), Sonata in C minor, Mvt II

No slurs in A & EE1

Slurs in GE (→FE,IE) & EE2

..

The slurs added in GE (→FE,IE) after analogous bar 74 can be considered justified. However, as the presence or absence of these slurs is only one of a few differences between bars 73-74 and 75-76 present in A, in the main text we do not include this addition.
The absence of the slurs in EE1 is almost certainly an oversight, corrected in EE2.

b. 77

composition: (Op. 4), Sonata in C minor, Mvt II

..

In A the L.H. part is written in shorthand – only top octave notes and the con 8va - - indication. In the editions it was written in full.
