'For this purpofe, the machine muft take the weight of every fuperior part from the Ipine ; it muft extend the fpine, and at the fame time leave every part between the pelvis and the head entirely at liberty : the machine, therefore, is to have a firm hold of the head, a certain fupport from the pelvis, and, when fixed to thofe parts, it muft be capable of an extenfion till the fpine is become ftraight, and all thofe parts which are attached to it are re- ftored to their natural and relative fituation.
