It is reduc'd as the other _Vertebra's_; but its Dressing and Bandage are made with the T perforated at the _Anus_, or else with the H or double T. It is made with a Band two Fingers broad, and long enough to encompass the Body above the Hips; so that to the middle of this Band is fasten'd another Band of the same breadth, and of a sufficient length to pass over the Dressing of the _Os Sacrum_, as also between the Thighs, to be join'd in the fore-part to the first Cincture. The double T is made by fastening two Bands at a Finger's breadth distance one from another, to the Band which ought to be roll'd about the Body; and this sort of Bandage is to be supported with a Scapulary. * * * * * CHAP. IX. _Of the Fracture of the _Coccyx_ or Rump-Bone._ This Bone is usually broken by falls, and sinks into the inside; so that to reduce it, the Fore-finger of one Hand is to be put into the _Anus_ or Fundament as far as the {284} Fracture, to thrust it back again into its place, whilst the other Hand setleth it on the outside. _The Dressing and Bandage._ Are the same with those in the Fracture of the _Os Sacrum_; but the Patient must be oblig'd to lie on one side, and to sit in a perforated Chair, when he hath a mind to rise. If the _Os Innominatum_ be broken, the _Spica_ is to be us'd after it hath been dress'd, of which Bandage we have given an Account in the Fracture of the Clavicle. * * * * * CHAP. X. _Of the Fracture of the _Humerus_ or Arm-Bone._ To set this Bone, a strong Extension is to be made, if the two ends cross one another, to which purpose the Patient is to be plac'd on a little Stool or Seat, and supported by a Servant, two other Assistants being employ'd to draw, one at the upper-part, and the other at the lower, above the Elbow, and not beneath it. In the mean time the Operator reduceth the two Bones, by closing 'em on all sides with the Palms of his Hands, and afterward prepareth {285} _The Dressing and Bandage._
