LIB. II. 35. 233 



non magis negatum esse igni, vivificare animantia, 

 quam maturare vegetabilia. Etiam inventum illud ce- 

 lebre Fracastorii 97 tie sartagirie acriter calefacta, qua 

 circundant medici capita apoplecticorum desperatorum, 

 expandit manifeste spiritus animales, ab humoribus et 

 obstructionibus cerebri compresses et quasi extinctos ; 

 illosque ad motum excitat, non aliter quam ignis ope- 

 ratur in aquam aut aerem ; et tamen per consequens 

 vivificat. Etiam ova aliquando excluduntur per calo- 

 rem ignis; id quod prorsus imitatur calorem animalem: 

 et complura ejusmodi : ut nemo dubitare possit, quin 

 calor ignis in multis subjectis modificari possit ad ima- 

 ginem caloris coelestium et animalium. 



Similiter sint naturae inquisitae, motus et quies 98 . Vi- 

 detur esse divisio solennis atque ex intima philosopliia, 

 quod corpora naturalia vel rotent, vel ferantur recta, 

 vel stent sive quiescant. Aut enim est motus sine ter- 

 mino, aut statio in termino, aut latio ad terminum. At 

 motus ille perennis rotationis, videtur esse coelestium 

 proprius ; statio, sive quies, videtur competere globo 

 ipsi terrae : at corpora caetera (gravia quae vocant, et 

 levia) extra loca scilicet connaturalitatis suae sita, 

 feruntur recta ad massas sive congregationes similium; 

 levia sursum, versus ambitum coeli ; gravia deorsum, 

 versus terrain. Atque ista pulclira dictu sunt.
