In the part of the L.H. in As only the first two crotchets in bar 77 are written out. It most probably means that the remaining four are to be completed after bars 5-6 (according to the numbering of the final version). In the presentation autographs one can see Chopin's hesitation, as far as the first crotchet in each of these bars is concerned; the version of AI is the most distant from the final version.
