Rules of Proportions.

FIrst, Euery Proportion is either taken away by the comming of his con∣trary proportion, or is broken by the interposition of a signe. As by the comming of a subduple, a dupla is taken away, and so of others.

2 Euery Proportion respecteth both Rests and Notes.

3 Euery Proportion of the great Inequalitie doth diminish the Notes and Rests with his naturall power: but the Proportion of the lesse Inequa∣litie doth increase them.

4 Alteration and Imperfection are onely in those Proportions, which are in perfect degrees, neither are they in all figures, but in those onely, which those degrees doe respect with their perfection, or to which these accidents besides the Proportion doe belong.

5 The sesquialtera Proportion doth exclude the Ternarie perfection of figures, vnlesse they haue it from a signe. Wherefore when the signe denies it; they receiue neither Alteration, nor Imperfection.
