Musorgsky's unfinished one-act setting of Gogol's 1842 comedy dates from 1868. A note on the front endpaper by Calvocoressi records that this proof copy was given to him in November 1908 by Diaghilev and contains autograph corrections by Rimsky-Korsakov and Glazunov.  There are a number of additions by Rimsky-Korsakov engraved on the plates and identified "Pribavlyeno N.R-K." (pp.49 & 56); a few other passages which diverge from Musorgsky's manuscript are also noted in the score (pp.6 & 10). The corrections by Glazunov can be readily identified here (initialled by him on pp.51 & 54), but, despite Calvocoressi's note, others are too slight to assign to Rimsky-Korsakov with any confidence.
