scacueram, ad te venire; cum nova occupatio fregit consiliumment
De honovifico Judicio tuo super mea de momencis dissercatione
acque euclide restiento, mirifficas tibe qracias ago. Hoc unum
superest, ut aliqued ipse dicam de dorcissimis tuis Animaduertio-
nibus, in elementa fauis; non que mea sim defensurus: sedue
raciones aperiam libi, quibui ad ducens sucacr, ea que convens
sum, sacis este posse ad Euclidis vescitucionem, quam milu quo-
posveram. Primum itaque monieum revolo, spreppuum meu
insticucum fuiste, ut ysdem Clemencis eam conciliarem clant
tacem, que esset quammaxime acomodata capeui Tyonum
qui si ipso in vestibule inevicuras figuvas offendant, scacim
confunduneur, acque animocadunt. Hoc factum est, uet Thaleris
demonstrationem, quam pag. 21. exposui, talem reliqueum, qua-
lem suus fecit Auccor, sine terey casus additione; tum quia Terrius
ille casus non dissimili vacione demonstratus; tum eciam, quia cum
hoc in Theovemate sit prema demonsrario negatiua, neque adhui syro
ex
assuecus sit concipere pro semicirculo figuram longe diversam qualis
est nocata AFC, facili negotio confundi is seoruisset:
Ce
id quod minime fit in sequence, mulioque minus in ea
que sequenti succedit; quia assuecus iam concipere
demonsvationem negativam in figuva facilis conscoue
tionis, nullam deinde difficultarem expevitur in aliis
implicatiovibus, ut in pag. 123. ubi nihil obsticie, quominus eundem casam
adderem.
