A comparison with FE, which is also based on [A], suggests that the earlier division of the slur in GC (→GE) is erroneous. The copyist's momentary distraction is also supported by the misplaced 
hairpin, one bar too early (see the previous note). Irrespective of the position of the division of slur, we consider the interpretation of the sources that reproduced it as coinciding slurs to be inaccurate; in the main text we interpret the first slur as a tenuto-slur and end it still in b. 176. It corresponds to the notation of GC as well as to the slurs of FE in an analogous phrase 4 bars ago.
