In order to cut off a Leg, the Patient is to be set on the side of his Bed, or in a Chair, and supported by divers Assistants; one of 'em being employ'd to hold the Leg at the bottom, and another to draw the Skin upward above the Knee, to the end that the Flesh may cover the Bone again after the Operation. In the mean while a very thick Bolster is laid under the Ham, upon which are made two Ligatures, _viz._ the first above the Knee, to stop the Blood, by screwing it up with the _Tourniquet_ or _Gripe-Stick_; and the second below the Knee, to render the Flesh firm for the Knife. Before the Ligature is drawn close with the _Gripe-Stick_, a little piece of Paste-board is to be put underneath, for fear of pinching the Skin. Thus the Leg being well fixt, the Surgeon placeth himself between both the Legs of the Patient, to make the Incision with a crooked Knife, turning it circularly to the Bone, and laying one Hand upon the Back of the Knife, which must have no Edge. Afterward the _Periosteum_ is to be {250} scrap'd with an Incision-Knife, and the Flesh with the Vessels that lie between the two Bones are to be cut. When the Flesh is thus separated, a Cleft Band is to be laid upon it, with which the Heads are cross'd, to draw the Flesh upward, to the intent that the Bones may be cut farther, and that it may cover 'em after the Amputation, as also to facilitate the Passage of the Saw. Then the Surgeon holds the Leg with his Left-hand, and saweth with his Right, which he lets fall upon the two Bones, to divide 'em asunder at the same time, beginning with the _Perone_ or _Fibula_, and ending with the _Tibia_. But it is necessary to incline the Saw, and to go gently in the beginning, to make way for it, and afterward to work it faster. The Leg being cut off, the Ligature must be unty'd below the Knee, loosening the _Gripe-Stick_, to let the Blood run a little, and to discern the Vessels with greater facility; and then the _Gripe-Stick_ may be twisted again, to stop the Blood; which some Surgeons effect, by laying Pieces of Vitriol upon the Opening of the Arteries, and Astringent Powders, on a large Bolster of Cotton or Tow, to be apply'd to the end of the Stump; but if such a method be us'd, it is requisite that some Person be employ'd to keep on the whole Dressing with his Hand during twenty four Hours. However this Custom hath prevail'd in the Hospital of _Hôtel-Dieu_ at _Paris_.
