In AI the part of the L.H. in bars 49-50 is not written out or suggested in any way (similarly in bars 51-63). It is a proof of an increasing draft nature of this manuscript from the middle of the Etude.

b. 51-63

composition: Op. 10 No 9, Etude in F minor

..

In AI all this fragment (from bar 49 on) is written without the part of the L.H. It undoubtedly means the use of figures which are similar to the previous ones to such an extent that the composer considered further notes in this respect to be superfluous. In bars 57-63 one can presume the use of the pattern written in bar 64, yet in the previous bars there are no indications on which possible additions could be based.
