In the proofreading of FE1 Chopin changed the b-f1 fifth on the last quaver in the L.H. into a b-d1 third. The absence of a respective correction in analogous bar 82 can be considered to be Chopin's oversight or, which is more likely, the engraver's mistake. Similar changes were also introduced by Chopin in the next bar – cf. annotations to the first, fourth and fifth L.H. quaver in bar 51.
