Peter Alphonse, Disciplina Clericalis (English translation… (1919)
“ Than the philosophre saide to the Right: 'Now comaunde yee that the cliere oile of the v ful tonnes be mesured and thow shalt knowe and wite how moche ther be of cliere oile; and in like wise of the v half tonnes and thow (f. 127b) shalt knowe how moche ther be of cliere oile. Than the thikke oyle of the v ful tonnes so measured and thow shalt know how moche thikke oile be in hem, and in like wise of the V half tonnes, if ther be asmoche as in the ful tonnes, know thow for a soth the oile is stolen. ”
