Geometria Agrimensoria
Euclides problema: in data recta infinita
alteri dutae aequalem ost poneres solvit
nobis in praxi pro postulato haberi potest
Omnia problemata simplicia solvuntur
intersectione rectarum. Ju campo unius tantum
rectae ductu opus est, et punctum intersectionis
cum alia ita invenietur; quae datis punctis
A et C, rectisque indernite
Positione datis interminatis
AB, Cd. quaeritur punctum
intersectionis E. Ducatur
alterutra, ut AB catena
scilicet vel fune protenso
ex pato in A defixo. Intrrca observa
for in C oculis intentis in D per piami
lam seu dioptram intentis, ubi primum
hunc qui funem vel catenam protendit pro-
gredientem praeterire ac sibi suis oculis
objici sive quod idem est punctum D tegere
videt, illic eum signo dato quiescere jubeat
et locus quietis erit punctum quaesitum
Omnia problemata planus solvuntur
intersectione circuli et rectae ut ergo
solius rectae ductu opus sit sic efficiemus:
sit recta AB secans circulum positione
et magnitudine datum in puncto C. quaeritur
punctum datum sine circuli descriptione
progrediatur observatur in ducta AB donec
cicculi centrum, D vident prumu ex dioptra
normali, quod fiet in puncto 2, quo invento
fatile invenientur F et G. visue et ambulatium
defigantur paxilli in Fet G. et observatur
