Juramentum

nullus custos alicujus cistae in praedicta universitate fundatae vel deinceps fundandae, libros aliquos, in papiro scriptos vel impressos, pro cautione sive parte cautionis quovis modo deinceps recipiat sub poena unius marcae universitati applicandae; et ad hoc statutum volumus singulos custodes in suis admissionibus corporale praebere juramentum. [no keeper of any money box into which money goes in or out in the aforementioned university shall receive any books written or printed on paper as a pledge or as part of a pledge in any manner under penalty of one demerit and to this statute we wish all guardians of the treasury to offer a bodily oath.] (40.)

Pierre Jonin notes that the equivocal oath--an oath designed to be ambiguous--was known during the Middle Ages under the name of juramentum dolosum.
