`_`	(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).

Paper, 341 f. (new foliation in pencil; this foliation jumps from 189 to 200, but nothing is missing there), a single neat hand copied f. 1r-183r and 185r-245v, and three other, sloppier hands copied f. 247r-266r, 267r-272v and 275r-341v. Old foliation and catchwords show that folia are missing (or misplaced) in several places, including at least between current f. 174-175 (20 folia acc. old foliation), somewhere between f. 175 and 185 (9 folia acc. old foliation), and also between 234-235, 283-284, 340-341 and after 341. The exemplar was, apparently, already defective, for the scribe noted after the explicit of Book II (175v): ‘Ex Theone nihil aliud omnino invenitur de secundo ac tertio libro Magnae constructionis’.

Ptolemaica (single text). Blank: 113, 176r, 184v, 246, 266v, 270v, 273v-274v.
