_ (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.

40r‑40bisv

‘Circulum pro exitu geniture ab utero iuxta verbum Ptholomei 51 rectificare. Sit tempus datum geniture — (40v) figura celi constituatur que erit finaliter rectificata.’

= Albertus de Brudzewo (?), Circulum pro exitu geniture ab utero iuxta verbum Ptolomei 51 rectificare (C.3.17). Substantial glosses by the scribe (Johannes Virdung), which are continued over an added sheet of paper (f. 40bisr-40bisv) and discuss a nativity of 1510. Some of the glosses are perhaps by another hand.

127r‑127v

‘Nature particulares signorum et facierum earum quas ponit Ptho<lomeus> secundo Quadripartiti, c<apitulo> 11, verificate per venerabilem egregiumque virum magistrum Petrum Gaschowicz me<dicine> doc<torem>. Totum signum Arietis facit tonitrua et relampagos (Pisces) faciens grandinem <de natura> Saturni’ (in the form of a table).

= Petrus Gaszowiec, Tabula de naturis particularibus signorum et facierum (C.2.6). No glosses. Followed by two added notes: ‘Item, octava sphera a tempore Ptholomey usque huc mota est 19 gradus et quasi per duas facies recessit octava sphera a nona’ and ‘Nature signorum sunt duplices ista natura loquetur presens tabula.
