    If a body be projected upward with the velo¬ city it acquired in any time by descending freely, it will lose all its velocity in an equal time, and will ascend just to the same height from whence it fell, describing equal spaces in equal times, both in rising and falling, but in an inverse order; and it will have equal velocities at any one and the same point of the line described, both in ascending and descending. If bodies be projected upward with any velo¬ cities, the height ascended to will be as the squares of those velocities, or as the squares of the times of ascending, till they lose all their velocities ; thus confirming the laws of Sir Isaac Newton, viz., that there was a law in nature, by virtue of which every particle of matter, that is, everything of which the earth is composed, draws towards it every other particle of matter with a force proportioned to its force and distance. Now the globe of the earth is a prodigious mass of matter, to which nothing near it can bear any comparison. It draws, therefore, with great force everything within its reach, which is the cause of bodies falling; and this is called gravita¬ tion or weight. Therefore it is to motion we are indebted to our remaining on this earth; for if the Creator of this wonderful universe were to
