Suppose this earth were A, which was to move in the circle C, D. and let the bullet be supposed at B. within its proper verge; I say, whether this earth did stand stil or move swiftly towards D, yet the bullet would still keepe at the same distance by reason of that Magneticke vertue of the center (if I may so speake) whereby all things within its spheare are attracted with it. So that the violence to the bullet, being nothing else but that whereby ’tis removed from its center, therefore an equall violence can carry a body from its proper place, but at an equall distance whether or no the center stand still or move. The impartiall Reader may finde sufficient satisfaction for this and such other arguments as may be urged against the motion of that earth in the writings of _Capernicus_ and his followers, unto whom for brevities sake I will referre them. Proposition 9. _That there are high Mountaines, deepe vallies, and spacious plains in the body of the Moone._ Though there are some who thinke Mountaines to bee a deformity in the earth, as if they were either beate up by the flood, or else cast up like so many heaps of rubbish left at the creation, yet if well considered, they will be found as much to conduce to the beauty and conveniency of the universe as any of the other parts. Nature (saith _Pliny_[1]) purposely framed them for many excellent uses: partly to tame the violence of greater Rivers, to strengthen certaine joynts within the veines and bowels of the earth, to breake the force of the Seas inundation, and for the safety of the earths inhabitants, whether beasts or men. That they make much for the protection of beasts the Psalmist[2] testifies, _The highest hils are a refuge for the wilde Goats, and the rockes for Conies_. The Kingly Prophet had learned the safety of these by his owne experience, when he also was faine to make a mountaine his refuge from the fury of his Master _Saul_, who persecuted him in the wildernesse.
