Verumquidem est mathematice loquendo radios hos per
circulum hunc paulo magis disporgi debere, cum antea
non ad unum punaum mathemalicum tenderent. Sed
dispersionem hanc tantam non esse, qu’in focum, sive
miminum planum ad quod postra ex vitro egressi ac aercm
transeuntes, tendent, et in quo congregabuntur, propuncto
mechanico habendum sit, simili calculo, aut etiam
mechanice, facile constare potert.
Sed cumplanum supra inuentum; cujus semidiameter est
1N indeterminatum sit, ac propius ad Naccedat aut magit
ab eo remoncatur, prout aportura, aut bF major aut
minor sumitur, determinatum planum ejus loco quavemus.
