After you have pierc'd the Swelling with a hot Iron, as for Hurts in the Withers, draw out the Tents twice a Day, syrenge the Holes with the Waters for Gun-shot-Wounds, and besmear the Tents with the Duke's Ointment, chafing the whole Tu∣mour with the same Ointment, and covering it with a Woolly Lamb-Skin, to secure the Wound against the Injuries of the Air or Wind. But if the Swelling have no vent, as it happens not unfrequently, you cannot make a perfect Cure, and therefore you must immediately make an Incision, as in the Withers, piercing to the Bottom of the Sore, and taking away all the dead and rotten Flesh. After you have wip'd off the Blood, apply hot Embers to the Wound, and the next Day wash it with warm Wine, Urine, or a convenient Lye, renewing the Application of the hot Embers three or four times after the same manner, and dressing the Wound like a Hurt in the Withers. If the Tumour tend to Separation, and cannot be dissolv'd, the best way is to rub the lower part of it with a Retoire, which opens the Swelling, and draws forth a red Water, and afterwards hastens the Generation of the Matter. If the first Application of the Retoire increase the Tumour considerably, there will be no need of a second: But if the Swelling be not much augmented, you most proceed to a second Application. If you have no Retoire, open the Swelling in the lower part with a red hot Iron, if the Matter be already form'd. If the Matter that runs out be bloody, or only a red Water, you may conclude that the Swelling is too soon open'd; but if it be white, the Sore will heal of it self, and your only care must be to keep the Hole open, and renew the Application of the red-hot Iron in case of Necessity. We are oftentimes oblig'd, if the Matter take up a large space, to make several Holes with a red-hot Iron, that we may have the Conveniency of thrusting a Tent from one Hole to another, for the more speedy uniting of the Skin to the Flesh.
If the Matter that runs out be Black, you have reason to fear a Gangrene, and must immediately search the bottom of the Sore with your Probe; for 'tis a certain Sign that the Seat of the Matter is remote, and the surest way is to make a large Incision to the bottom of the Sore, with a Razor, and so dip the Bolsters of Flax in the Vulnerary Water or Lime-Water with Sublimate, stopping the Wound with Tents, and anointing all the external parts of it with the Duke's Ointment. If you perceive the Matter that runs out next Day to be very stinking, 'tis a sign of great Corru∣ption, and therefore you must cut away all the corrupt Flesh, till it appear fair and clean; strew the Sore with Salt, and afterwards for the greater Security wash it with the Vulnerary Water, or the Yellow-Water, as before, applying the Duke's Ointment about the Sore to all the parts from whence you suspect the Matter may come. Afterwards when you perceive no more dead or rotten Flesh, strew the inside of the Sore with Salt, and apply a Detersive, such as the Neat-herd's Ointment for Gauling, or Aegyptia∣cum mixt with Aqua-fortis; and when it begins to grow of a fair red Colour, dress it with Schmit's or the Doctor's Ointment, using your utmost Diligence to prevent a Gan∣grene in the Summer; for during the Winter Wounds are not so much subject to that fatal inconveniency.
Lapis Mirabilis is good to resist Corruption, as also the above-mention'd Vulnerary-Water, and for want of that the Yellow-Water; but the Spirits of Vitriol or Salt are bet∣ter, besides several others; all these Remedies ought to be apply'd in case of Ne∣cessity, when the Matter that runs out appears of a Black Colour, which is one of the greatest signs of Corruption.
If you cannot stop the Blood after the opening of an Abscess, sear the part; for besides the conveniency of stanching the Flux of Blood, the falling away of the Scab will promote the Cure; and at last when 'tis time to compleat the Cure, the regular application of the Hermit's Ointment will quickly perform the Work.
An excellent Digestive.
Take fine Turpentine and Honey of each two Ounces, the Yolks of four Eggs, half an Ounce of Myrrh, and an Ounce of Alloes in Powder; mix all the Ingredients cold, and you will have a Digestive that hinders the Corruption of the Flesh, and takes away all the Pain occasion'd by the violence of the preceding Reme∣dies.
The usual Digestive of Farriers is compos'd of Turpentine incorporated with the Yolks of Eggs to the thickness of an Ointment, of a pale Citron Colour, which is a good Remedy, but inferior to the former.
