Sit AB Atylus rectuo, cuguo per in plano
horoloqus eot punctum B, apex vero est punitum
A, extra peanum horologus in aere: sintque
C, D, F, tria umbrae punita in eodem plano
horologis, profecta ab apice styla A, quacunq
anni die, et qua cunque quodem diec hora.
Ilo positis, si a styer apice A, ad tua
umbra puncta data C, D, F, ducantur tres
rectae AC, AD, AF, Dico ipsas esie in illa
superficce, quam umora apucis styli eo die
deveribit.
Cum enim umbra, quae a styer apice A
procedit, duffundatar tota per lincam acctam
Ergo dicta umbra, eo ipso tempore quo obsernata
a
2. ax. 14 fuerunt tuo ipous puncta, c, D, E, diffundibatur
tota per rectao AC, AD, AF., ac proinde idem
spatium cum ipsis tunc occupabat: et quia
eadem umbra toto illo die reperta fuit in
ill’a super ficce quam ipon descripsit; ergo
et rectae AC, AD, AF, cum quibuo conjunitam
fuit, in eadem quoque superfuce reperiri
debent. Z. E. D.
Schoecum.
Obseruandum est, vel unum eexe tubus
umbrae punctio datio v. g. D. vicinrus esse
Atger apier A, quam duo reliqua, C, F; vel
duo puncta cidem apier viciniora C, D,
aequaliter ab ipio orstare; vel denique, omnia
dictaumbrae puncta, C, D, F., ab eodem apice
aequaliter es. remota; quibus sinqulis cacibus
omnes sequentes propoones ex ordine reopondebunt.
