b. 46

composition: Op. 10 No 4, Etude in C♯ minor

..

In AI there are no naturals before the 4th and 12th semiquavers (in both hands). The signs in the 1st half of the bar are of cautionary significance, yet in the 2nd half of the bar they are necessary. Moreover, the  lowering d1 to dwas omitted. All the aforementioned signs appear in FE (→GE,EE).

b. 72-74

composition: Op. 10 No 4, Etude in C♯ minor

..

We add cautionary sharps before d2 in bars 72 and 74. The signs were already added in GE, while the second of them also in EE4. In bar 74 FE (→GE1,EE) has an additional unjustified  before the 12th semiquaver (c3). This probably erroneous sign was removed in subsequent GE,s.
