Primum vobis praesento artium plurimarum Scholae Parisiensis professorem, quem in
hoc ipso loco die hesterno perspicuitate solita disserentem audivistis, virum non modo solis
de lumine in partes suas solvendo, sed etiam orbis terrarum de mole metienda per annos
plurimos praeclare meritum. Lucis in natura explicanda, quanta cum doctrinae elegantia,
quanta cum experimentorum subtilitate, quam diu versatus est. Idem quam accurate
velocitatem illam est dimensus, qua per aeris intervallum immensum lucis simulacra
minutissima transvolitant,
'suppeditatur enim confestim lumine lumen,
et quasi protelo stimulatur fulgere fulgur.'
Lucis transmittendae in Xa/iraî7jcopta quam feliciter lampada a suis sibi traditam ipse
etiam trans aequor Atlanticum alii tradidit.
Duco ad vos ALFREDUM CORNU.
