m. 1: First rhythm symbol looks like a dotted half, but it has to be 
undotted.
m. 8: "10x" is indicated in original by "Questo primo tempo farassi 
dieci volte" and by a 10-dotted double bar.
m. 24: Instead of a tab number, original has a large 3 (as for a time 
signature) with a half-note rhythm symbol. I've made this III-0; I 
think that's the most plausible choice.
m. 24a: Quarter-note rhythm symbol is over last note; I've interpreted 
it as if it were one note earlier.
mm. 37-38: Barline between these two measures is missing.
m. 41: Original time signature is 3.  It's under the first rhythm 
symbol, but should probably be to the left with space for a rest, and 
I've transcribed it this way. I've supplied an opening repeat bar at 
the beginning of this measure, but quite likely it should go after the 
rest.
mm. 76-77: Barline between these two measures is missing.
m. 79: First chord should possibly be 3--13-, by analogy with several 
similar spots.
