mido, & poſita inclinata, nec conuertetur ita, ut
axis ipſius ſecũdum perpendicularem ſit, nec ma
nebit inclinata, niſi quãdo axis cum ſuperficie hu
midi angulum fecerit æqualem angulo ſimiliter
ut prius, aſſumpto.

SIT portio, qualis dicta eſt: ponaturq; d b æ qualis axi
portionis: & b _k_ quidem ſit dupla ipſius _k_ d; k r autem
æqualis ei, quæ uſque ad axem: & c b ſeſquialtera b r.
Quam uero proportionem habet portio ad humidum in
grauitate, eam habeat exceſſus, quo quadratum b d exce-
dit quadratum f q, ad ipſum b d quadratum: & ſit f ipſius
