The pitch of the middle note in the penultimate triplet (in both bars) raised doubts of many later editors of Chopin's works. In fact, there are many arguments that make one consider an oversight of the  restoring d2(1) to be likely. However, as the literal interpretation of the text results in a version that perfectly fits into the Chopinesque style, in the main text we leave the source version.

b. 321-322

composition: Op. 2, Variations, complete

..

In A there are no accidentals to the last semiquaver on each beat of the bar – Chopin considered the accidentals written to the earlier notes placed an octave lower to be valid (AsI is slightly more accurate, since it includes a  to c2 in bar 321). In GE1 (→FE,EE) these accidentals were added only just starting from g2, the last semiquaver in bar 321. In GE2 (→FESB) a  to e2 was also added, while in GE3 also a  to c2.
In the main text we give all the omitted accidentals and omit the unnecessarily repeated  to f2 at the beginning of the last R.H. triplet.
There is a similar situation in bars 324-325 and 327-328.
