Si fuerint magnitudines continue proportionales: erit ut terminus rationis major ad terminum rationis minorem, ita differentia compositæ ex ombinbus & minimæ ad differentiam compositæ ex omnibus &
If there are magnitudes in continued proportion, then the ratio of the greatest term to the least will be as the difference between the sum of all and the minimum to the difference between the sum of all and the maximum.
