1^4 The Farrier^j" New Guide. Ch. XLVIIL 



The wet and the dry only differ as there is more or lefs 

 Moifture in the Ulcers and Parts where it is feated^ the flying 

 Farcin, which makes its Appearance fometimes in one place, 

 fometimes in another ; and the inward Farcin, which is faid 

 only to be felt on the Bread, but does not elevate the Skin, 

 and is obferved often to difappearof a fudden, and become 

 the immediate Caufe of Sicknefs, though either ofthefe may 

 degenerate to a true Farcin, yet while they are not fixed, 

 but indu'd with Properties altogether foreign to the Farcin, 

 they cannot rightly be brought under that Denomination, 

 but ought rather to be looked upon as refembling thofe E- 

 ruptions on the human Body, which happens in violent 

 Colds, or malignant Diforders, and are curable as fuch. All 

 the other Kinds are only different Effeds of that which 

 makes its firll Appearance like a knotted Cord ; and it is 

 this Sort alone, which, properly fpeaking, conftitutes a true 

 Farcin. In what Manner fuch a Difordcr can happen to 

 a Horfe, and produce thofe Effeds we daily obferve from it, 

 fhall be fhewn anon. 



We have already taken Notice, that the Farcin has its chief 

 Seat in the Skin and thin mufcular Pannicle, which lies 

 under it, and is caufed when the Juices in thofe Parts are 

 become vifcid, and confequently flow and languid in their 

 Motion. If it be confider'd that there is an infinite Number 

 of Veilels in thofe Parts that are fmaller than Hairs j and 

 that thofe Vellels, however fmall, have a Capacity, and 

 contain a Fluid within them, ^ny one may eafily imagine, 

 that in the beft Eftate a Horfe can be in, that Fluid can 

 move but very flowly ; but when it happens to be too thick, 

 or vifcid, it may be then eafily reduc'd to a State of Stagna- 

 tion ; and when it is deny'd a free Paflage thro' thofe fmall 

 Canals, as it is conllantly prefs'd upon it by the fucceeding 

 Fluid, thofe fmall Veflels, where there is a Stagnation, will 

 be llretched out beyond their ufual Dimenfions, and the Part 

 will be elevated and raifed into a Tumour. 



As often as any Part is thus elevated, and the Liquor flopt 

 that it cannot move forwards, becaufe of the Obftrudions 

 and the Compieflions there is on all Sides, the Veflels being 

 thereby fiU'd beyond their Capacity, it burfts forth ; and be- 

 ing now got without the Laws of Circulation, putrifies, and 

 acquiring a corrofive malignant quality, it gnaws and fefters^ 

 until it has form'd a convenient Lodgment for itfelf. 



If the Stagnation be fudden and violent, and accompanied 

 with great Pain and Heat, it will caufe fo great a Deriva- 

 tion of Blood towards the inflam'd Part, that the fubjacent
