Figure Vpon the Threds da & ce hang the bodys d & e. & exactly twixt them hang the spring sbt by a thred soe that it have liberty to move any way. then compresse the spring bs to bt by the thred st. Then cutting | clipping the thred st the spring shall cast both the body d & e from it & they receve alike swiftnes from the spring if there be the same quantity of body in both otherwise the body bo (being fastened to the spring) will move towards the body which hath less body in it. which motion may be observed by compareing the motion of the point (o) to the point p & other points in the resting body qv.
