Coenica rarione densicarum; dataque sphaera actiuitacis,

Tumen videtur esse intensins in minore, quam in maiore; licet non sit

SLumen, quod ex medioraro, superficie spharica terminato, subit in den-
sum medium, nullo modo refrinsitur.

6Lumen, quod praedicto modo, d raro medio eadit in densum, incensius est
in prima illa superficie densi, quam si tancum per medium densum,
secundum eamdem distantiam; vel radis lonsiudinem diffusum esset.

 In hac eadem hyporhest, qua soilicet e sphaera medy rari, subit lamen in
