We therefore Publish, by the Divine assistance, these our En∣deavours also, after so many other ingenious and elaborate ones in the same kind; nor can we doubt the approbation of some of our Readers. This at least we can experimentally affirm: That not a few of those to whom these our thoughts were partly pub∣lickly read in Lectures, and partly privately taught (for they were only design'd for Learners) were not a little taken with the Concise brevity and facility of the Demonstrations; so that we may reasonably hope to be acceptable to those, to whom ei∣ther time, or sufficient force of genius is wanting, to run over the vast Volumes of the Ancient Mathematicians, and compre∣hend their prolix Demonstrations, and long series's of far fetch'd Consequences; and as for those who have both leisure and geni∣us to do so, this may serve for an Encouragement towards it; that after they have gone through the chief truths and propo∣sitions

they contain, Demonstrated in a more easie and shorter way, they may so much the more confidently adventure upon those celebrated and ingenious Treatises, from the reading whereof they were before deterr'd by the length and almost insuperable diffi∣culty of their tedious and perplext Demonstrations.
