In these bars Chopin overlooked the naturals lowering g
(1) to g(1). It is proven by the absence of those accidentals in FE (→EE) and by the fact that they were added in print in GE, which is indicated by the gaps between the notes. The authenticity of the additions to GE is not confirmed, yet Chopin's mistake is evidenced by analogous b. 119-120, in which accidentals are present in all sources.
