Fetivicarem aurem ab Obliquicate, de Snelinatione, (quamquam ex una reli-
qua dependeane,) diltinsuere necesse duxi; quoniam Obliquitas  Incli-
natio Angulis menturari tolene; Ea rero Dessivilatis racio mihi cractanda vide

rudine aequalium proporcionalia, vel in reciproca ratione Reclarum Alcicudinc
raqualium, in segiencibus deprehendentur.
