_ (the underscore) is the placeholder for exactly one character.
% (the percent sign) is the placeholder for no, one or more than one character.
%% (two percent signs) is the placeholder for no, one or more than one character, but not for blank space (so that a search ends at word boundaries).

At the beginning and at the end, these placeholders are superfluous.

I, 1ra-8ra; II, 8ra-12vb (abrupt end in II.9.20 in the middle of a word at the bottom of f. 12v; the catchwords ‘particularia observare’ show that the text was originally more complete). A few short marginal notes by the scribe and perhaps by another hand.
