Are made with a Plaister cut in form of a _Malta_ Cross, which is apply'd at the middle to the end of the Finger, the Heads being cross'd round about. The Bolsters must be also cut in the shape of the _Malta_ Cross, or of a plain Cross only; the Band being a Finger's breadth {264} wide, and long enough to be roll'd about the whole Dressing: It must be pierc'd at one of its ends, and cut the length of three Fingers at the other; so that the two Heads may pass thro' the Hole, to surround the Finger with small Rollers. * * * * * CHAP. XXXI. _Of the Reduction of the falling of the _Anus_._ To reduce the _Anus_ to its proper place when it is fallen, the Patient being laid upon his Belly, with his Buttocks higher than his Head, the Operator gently thrusts back the Roll that forms the _Anus_ with his Fingers dipt in the Oil of Roses: Then he applies the Bolsters steept in some Astringent Liquor, and causeth 'em to be supported with a sort of Bandage, the Nature of which we shall shew in treating of the Fracture of the _Coccyx_, that is to say, the T. the double T. or else the Sling with four Heads. * * * * * {265} CHAP. XXXII. _Of the Reduction of the falling of the _Matrix_._ In this Operation, the Patient being laid upon her Back, with her Buttocks rais'd up, Fomentations are to be apply'd to the Part; a Linnen Cloth is to be laid upon the Neck of the fallen _Matrix_; and it is to be thrust very gently with the Fingers, without using much force. If the _Matrix_ shou'd fall out again, it wou'd be requisite to convey a Pessary into it, after it hath been reduc'd; and to enjoyn the Patient to lie on her Back with her legs a-cross. * * * * * CHAP. XXXIII. _Of the Application of the _Cautery_._ The Cautery is an Ulcer which is made in the Skin, by applying Causticks to it, after this manner: The Surgeon having moisten'd the Skin for a while with Spittle, or else having caus'd a light Friction to be made with a warm Cloth, applies a perforated Plaister to the Part, and breaks the Cautery-Stone, to be laid in {266} the little Hole, leaving it for a longer or shorter time, accordingly as he knows its Efficacy, or as the Skin is more or less Fine. Afterward he scarifieth the Burn with his Lancet, and puts a Suppurative, or piece of fresh Butter into the Part, till the Escar be fallen off. _The Dressing and Bandage._
