When two forces act upon a body at the same time ittakes a direction intermediate. This is known as The enormous by the heavenlybodies will be treated of later. We will first Shoclc communicated by elasticity. There are several experiments relating to the subject ofInertia which may be performed. I once witnessed onequite accidentally when taking a walk. I was one day passing the Observatory at Paris, whenI noticed a number of people collected round a professor,who after executing several juggling tricks, proceeded toperform the curious experiment I am about to took a broomstick and placed it horizontally, passingthe ends through two paper rings. He then asked two 52 SOLID BODIES.
