In the main text we add a cautionary 
before e on the 2nd quaver. The accidental is written in pencil also in FC; however, it is an addition of Hermann Scholtz, a later owner of the manuscript. In GE, which also includes that , one can see that it was added at the time of proofreading the print version, since there was no place for it at the stage of laying out the text. Therefore, it is an editorial revision.
