The "Parte Terza" also has very similar text: 6 divisions* in line, 6 divisions at speed, attack and defence in line, attack and defense at speed.
Comparing to
Le Marchant, we seem to have gained running at heads and lost the "sword arm protect" (in my opinion, a rather poor trade). Le Marchant also addresses (p75) the near side pursuit, which (perhaps due to skimming and very poor italian) I did not find in Weiss.
* I am not sure these are the same exercises: again, it may be poor italian, but Le Marchant gives some individual and 2 vs. 1 exercises while it appears to me that Weiss is always talking about a whole line performing an exercise.
