Seven or eight Days before the Application of the Fire, the Parts must be soften'd either with Baths or Fomentations, such as are mention'd in the Chapters that treat of tyr'd and decay'd Legs, or with softening Remedies, such as are prescrib'd for the Cure of Splents: For thus the Humours are dispos'd to yield to the Operation of the Fire, which finds less Resistance, and more effectually dissipates and dissolves 'em.
The Part being soften'd, you must proceed to give the Fire gently and dexterously, according to the Nature and Situation of the Part, either in the Form of a Feather, Rose, Shield, Palm of the Hand, or any other convenient Figure.
The Fire thus dextrously and lightly given to a Part that is already soften'd, will produce a much more considerable Effect, than the most violent Fire that can be ap∣ply'd, without a due Preparation of the Part by softening Remedies.
After the giving of the Fire you may apply yellow Wax melted, and mixt with black Pitch also melted, with Shavings of Cloth over all; and after nine, ten, or twelve Days, when the Scabs fall away, wash the burnt Part once a day with Brandy. I seldom use Plaisters in these Cases, since the Cure may be effectually perform'd by anointing the burnt Parts once a day with a Mixture of Brandy and Honey, and by washing the Sores with Brandy alone after the Scabs are fall'n. 'Tis true when the Skin is pierc'd, 'tis absolutely necessary to apply a Plaister to concentrate the Heat of the Fire, that it may operate with greater Vigour: But when the Skin is only sear'd, as in the Cure of a Farcin, the Fire does not stand in need of that Assistance. The Scab falls away of it self, and leaves a less visible Mark, than when Wax, Pitch, or any Plaister is apply'd, which commonly brings away such large Pieces of the Skin, that the Place remains ever afterwards mark'd and deform'd.
You must give the Fire with a Knife that has a pretty thin Edge, but rather round than sharp, and always rub it on a piece of Wood when you take it out of the Fire; for the Ashes that stick to it wou'd cut and fester the Skin. You must also observe to follow the Hair, that it may cover the Marks after the Sores are heal'd. Thus, for Example, when you have occasion to give the Fire on the Sinews of the Fore-Legs, you must draw a Line or Rase downwards between the Sinew and the Bone on both sides, and three or four more upon the Sinews at equal Distances, rather than imitate those who draw cross Lines, as if they were going to broil a Fish.
'Tis a needless Piece of Curiosity to apply drying and Restringent Ointments to the burnt Parts, unless when the Skin is pierc'd, and there is Reason to fear a large and unseemly Scar. These Ointments are thus compos'd; Take Tarr and Burgundy Pitch, of each half a Pound; Bole-Armenic and Seal'd-Earth, of each six Ounces; Turpentine and Rosin, of each four Ounces; Powder of Roses an Ounce: Mix and make an Ointment. But Farriers use only black Pitch, because 'tis cheaper, and more easily procur'd.
I will not pretend to restrain any Man from observing this Method; but I believe it may be better omitted, for when a Scab falls away of it self, it leaves the Skin that is next to it entire, and the Scar is less apparent. I acknowledge 'tis necessary to apply a Plaister in some Places, to concentrate the Heat of the Fire, that it may dissolve the Swelling more effectually, especially in such Parts of the Body, where a Scar does not occasion any considerable Deformity. 'Tis also to be observ'd, that those who design to apply a Plaister must draw the Stroaks at a greater distance than 'twou'd other∣wise be necessary to do. Almost every Farrier has a peculiar Method of giving the Fire; some perform the Operation with a Piece of four Pistoles, some with a Silver Knife, and others with one of Copper, which I believe is the most convenient Instru∣ment, for Copper resists Corruption, and cleanses Wounds. Gold is certainly endu'd with many excellent Virtues, but I have often observ'd, that, contrary to the common Opi∣nion, it makes a very large Scab, and leaves and ugly Scar. There is something very soft in Silver, and its Fire is not so sharp and fierce as that of Gold: But to avoid a needless Charge, I have hitherto us'd Copper Knives with very good Success, and I shall always prefer 'em before Gold, tho' not before Silver.
I cannot forbear repeating the important Advice I have already given you, never to make your Knife too hot, and to heat it always in a Charcoal-Fire; for there is a certain Sharpness in Sea or Pit-Coals, which makes a very large Scab.
'Tis to be observ'd that the Fire does not generally produce a very quick Effect; and I have sometimes observ'd that it exerts not its utmost Vigour till six Months after it is given: For 'tis an insensible and slow-pac'd Resolvent, and requires a very considerable space of time, before it can digest and concoct the Humour; and therefore every Man that resolves to have Recourse to this Method, must arm himself with
