The _Capeline_ or Head-Bandage, having two Heads, is made with a Band of the same breadth, but somewhat longer. This Band being at first apply'd to the middle of the cut Part or Wound, the Heads are carry'd up above the Knee; and one of the Ends are turn'd backward, to bring it down, and to pass it over the end of the Stump. At every back-fold which is form'd above and below the Knee, a Circumvolution is to be made with the other end of the Band, to strengthen the back-folds, continuing to bring the Band downward and upward, till the whole Stump be cover'd: Then Rollers are made round about the Stump, and the Band is stay'd above the Knee. Afterward the Part may be brought to Suppuration, cleans'd and cicatriz'd. * * * * * {253} CHAP. XXII. _Of the Operation of the _Aneurism_._ This Operation is perform'd when the Surgeon hath prickt an Artery, or when a Tumour ariseth in an Artery. To this purpose the Patient is set in a Chair, and a Servant employ'd in holding his Arm in a Posture proper for the Operation; then a Bolster is to be laid four double, following the Progress of the Artery, to the end that the Ligature may better press the Vessel; and the Arm may be also surrounded with another single Bolster, on which is made a Ligature screw'd up with a _Gripe-Stick_, provided the Arm be not too much swell'd; for in this Case it wou'd be more expedient to deferr the Operation for fear of a Gangrene. The Artery being thus well stopt, the Surgeon lays hold on the Arm with one Hand, below the Tumour, and with the other makes an Incision with his Lancet, beginning at the bottom of the Tumour, and ending on the top along the Progress of the Artery. When the Tumour is open'd, the coagulated Blood may be discharg'd with a Finger; and if there are any Strings at the bottom, they may be cut with a crooked Pair of Sizzers, to the end that all the Clods of Blood, and other extraneous Bodies which are sometimes form'd in _Aneurisms_ when they are very inveterate may be more {254} easily remov'd. But the _Gripe-Stick_ must be loosen'd, to discover the Opening of the Artery with greater facility, and the Artery separated from the Membranes with a Fleam; for it wou'd be dangerous to cut it with a streight Incision-Knife: The Artery must also be supported with a convenient Instrument to divide it from the Nerve and Membranes; and to be assur'd of the Place of its Opening, the _Gripe-Stick_ may be somewhat loosen'd, and afterward screw'd up again. In the mean time the Surgeon gives the Instrument to a Servant to hold, whilst he passeth under the Artery a crooked Needle with a wax'd String, cuts the Thread, and takes away the Needle: Then he begins to make the Ligature beneath the Opening of the Artery, tying at first a single Knot, on which may be put (if you please) a small Bolster, that may be kept steady with two other Knots: It is also necessary that another Ligature be made in the lower part of the
