1neæ ſcilicet KG propior erit,
quàm circumferentia Dk li
neæ DG. quare linea CD
ponderi in D magis renititur,
quàm linea C k ipſi ponde
ri in K. ergo pondus in k
grauius erit, quàm in D.
Similiter oſtendetur pondus,
quò fuerit ipſi F propius, vt
in L, minus grauitare: pro
pius verò ipſi G, vt in H,
grauius eſſe.
