QVoniam nedum in hyperbola, ſed etiam in ellipſi quadratum A C ad ſum-
mam quadratorum ex I L, &
ex N O eandem proportionem habet, quã
A H ad ſummam ipſarum H E, &
E G, atque quadratorum ex I
L, &
ex N O ſumma ad eorundem quadratorum differentiam eandem propor-
tionem habet, quàm ipſarum H E, &
E G ſumma ad earundem differentiam;
387[Figure 387] evgo ex æquali quadratum A C ad quadratorum ex I L, & ex N O differen-
tiam eandem proportionem habet, quàm C G, ſiue H A ad ipſarum H E, &

E G differentiam;
ſed in ellipſi ipſarum H E, & E G differentia æqualis eſt
duplo E D;
igitur in ellipſi quadratum A C ad quadratorum ex I L, & ex
N O differentiam eandem proportionem habebit, quàm præſecta C G ad duplum
inuerſæ E D.
Notæ in Propoſit. XXVII.
ET oſtenſum iam eſt, quod I L in hyperbola maior eſt, quàm A C;
11C ergo differentia A C, & illius coniugati maior eſt, quàm differen-
tia homologorum ſuorum à ſuis coniugatis, &
differentia proximioris ho-
mologi ad ſuam coniugatam maior eſt differentia remotioris à ſua coniu-
gata, &
c. Hoc autem ſic demonſtrabitur. In diametris A C, & I L produca-
tur A M æqualis Q R, &
I K æqualis N O, & ab ijsdem ſecentur A S æqua-
lis Q R, &
I T æqualis N O. Quoniam M S bifariam ſecatur in A, & e
