Is made thus: The Surgeon having laid a Bolster upon the Orifice, keeps it close with two Fingers, and holds the Band or Fillet with the other Hand; then taking one end of the Fillet with the Middle-Finger, Fore-Finger, and Thumb, and applying it to the Bolster, he makes with the longest end of the Fillet divers Figures in form of the Letters KY in the Fold of the Arm; as also a back-fold with the shorter end of the Fillet, held between three {257} Fingers. Afterward both ends of the Fillet are ty'd beneath the Elbow. If an Inflammation happens after the Operation, the Bolsters are to be dipt in _Oxycratum_: but if the Orifice were so small as to produce a _Rhombus_, it wou'd be requisite to press the Wound often with two Fingers, and immediately to apply a Bolster dipt in _Oxycratum_. * * * * * CHAP. XXIV. _Of the Operation of _Encysted Tumours_._ If the Tumours are small and hanging, and have a narrow bottom, a Ligature may be made with Horse-Hair or Silk, dipt in _Aqua-Fortis_, which will cause 'em to fall off of themselves after some time; or else they may be cut above the Ligature. If the Tumour or Wen be thick, and its bottom large, a Crucial Incision is to be made in the Skin, without impairing the _Cystis_ or Bagg; and when the Incision is finish'd, the Bag may be torn off with the Nails, or with the Handle of a Pen-Knife; but sometimes it is necessary to dissect it. If there be any considerable Vessels at the Root, they may be bound, or else cut; and the Blood may be stopt with Astringents. If any parts of the _Cystis_ remain, they are to be consum'd with Corrosives; and the Lips of the Wound are to be drawn together without a Stitch, making use {258} only of an agglutinative Plaister. But if the Tumour adheres very close to the _Pericranium_, it is most expedient not to meddle with it at all. _Of _Ganglions_._ _Ganglions_ are Tumours arising upon the Tendons and Nervous Parts, which may be cur'd by thrusting 'em violently, and making a very streight Bandage, provided they be very recent; a resolvent Plaister is to be also apply'd to the Part. * * * * * CHAP. XXV. _Of the Operation of the _Hydrocephalus_._ This Operation is perform'd when it is necessary to discharge watry Humours out of the Head: If these Waters lie under the Skin, a very large Opening is to be made with a Lancet, and a small Tube or Pipe left therein to let 'em run out. If the Water be situated between the Brain and the _Dura Mater_, the Membrane is to be perforated with a Lancet, after the Trepan hath been apply'd, according to the usual Method, of which we have already given some account: Cauteries and Scarifications may be also us'd to very good purpose in this Disease. * * * * * {259} CHAP.
