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

 Moifture in the Ulcers and Parts where it is fcated, 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 Breaft, 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 difterent EfFecb of that which 

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

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

 Farcin. In what Manner fuch a Diforder can happen to 

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

 Ihall be (hewn 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 itbeconfider'd that there is an infinite Number 

 of Vefl'els in thofe Parts that are fmaller than Hairs ; and 

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

 contain a Fluid within them, any one may eafily imagine, 

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

 move but very llowly ; 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 conftantly prefs'd upon it by the fucceeding 

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

 be fliretched 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 fl.opt 

 that it cannot move forwards, becaufe of the Obfl:rudtions 

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

 thereby fill'd beyond their Capacity, it burlls forth ; and be- 

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

 acquiringa corrofive malignant quality, it gnaws and feltcrs, 

 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
