occursu medii minus resistentis seu densioris

Alia ergo ratione exilicanda videtur refractio
ut appareat non tantum cur radius inflectatur. d
cum in medium rarius incidit, sed et postea cur in medium
densius ingressis rectituatur
Fermatius assumsit contrariam Hypothesin Cartesiane
nam Cartesius poinit medium rarius magis resistere et ita
explicat refractionem eo modo quem dixi, et quem imperfectum
esse Ostendi. At Fermatius contra ponit medium densius magis
resistere: atque ita procedit: Videri naturam radium  ex
