smaller and smaller

I practiced calligraphy a little bit tonight, trying to sort out a hand similar to the one used in Florius de Arte Luctandi. That's dip pen, on graph paper ruled at five squares to the inch; I ought to be working even smaller, but that's the finest calligraphy nib I've got right now.

The Florius manuscript has a really interesting abbreviation for word-final ms that looks like a cursive letter z. I need to incorporate it when I do the final draft.
