Efle repellentes vires, atque efletrahentes;
Unde queant motu partes turbante agitari ,
Qui fecus haud certe copflct , nam Lola repellens
Vis fubito quafvis procul in fpatia ampla fugaret ,
Et vis fola trahens denfaret corpus in unugi.
Proin nonhasc rerum, gravium velut, & coeuntum , Lopj
/Eque materiem vis efl diffufa per omnem ,
Ali
agitat varie variam, neque corpore conflat
Mutato: fervet fubito hoc cum corpore corpus
Hoc mixtum, fed non alio fervifccrc cernes,
Lentius aut multo , ac languentius exagitari.

Deinde 1 neque , ut gravitas, vis
hxc
manifefla patelcit
Ante oculos* nobis; quis leges prodidit ejus
