Quod calybe igncfccntc vides, &, fcpc metalli
Fufi in fupremo faciei cortice, quadam

Incipiet pollquam nutivo frigore ftringi.

Fortior eft, quam qui de pellucentibus extra
Lamellis rcfilit, fic multo fortior idem eft
Lxfilicns fronte a quavis fplendente metalli,
Quam vitrea de fronte , undofaque, aeriaque.
Nec videas, cur non poffint, denfiffima qux funt
Corpora, fi partes habuere repulfibus aptas ,
Lumen id omne, quod incurrit, reflectere, proinde
Lucenti mage, quam quidquam, candore nitere;
Dcnfi ubi quandoquidem refringens corporis eft vis

Hile reflexorum; facies proin fplendida longe.
Multaque prxtcrea funt, queis hxc vincere poflis
Conjcdans, fufis liquefada metalla metallis
