CXXIV. PROBLEMA.
Magnitudinem ampliatae speciei artificiose aestimare.
Dirigatur sinister oculus in rem visibilem sine instru∣mento liber; dexter vero trans lentes eandem aspiciat. Cum igitur sinister sit in visibile directus, dexter autem sinistro sponte sua semper maneat parallelus, si tegatur ut jam instrumento legitur, quippe parallela oculorum directio est naturalis per LVII. dexter igitur quasi in visibile ipsum directus erit, sive ei species Instrumenta∣ria humilior, sive altior videatur re ipsa per oculum sini∣strum visa. Nam per LXII, videbit quidem dexter o∣culus speciem ampliatam rei illius, in quam rem ipse per associationem sinistri dirigitur; sed non ideo videbit illam eadem semper sui particula, qua sui particula sinister eam videt.
Quando ergo situ discrepare videbuntur species, lente con∣vexa instrumenti huc illuc mota, interdum & concava paulo aliter oculo applicata, facile efficietur ut species utraque visibilis ejusdem inter se situ congruant. Tunc igitur ap∣parebit excessus alterius supra alteram, applicatis invicem speciebus.
