away by this inveterate Diflemper. By what Steps it 

 proceeds, and how the Matter comes to alter its Colour, 

 I will give you my Opinion. 



" The Mafs of Blood beinp; depraved, either by un- 

 wholfome Food, or by great Colds, or Laftly, by In- 

 fedion from the Air, and from other Horfes ffor this 

 Diftemper is catching) this phlegmatick Matter colled- 

 ed in it, is fpued out of the Ends of the Arteries in the 

 upper Part of the Noftrils, about the fpongy Bones chief- 

 ly; for in an Horfe there is little of this Matter comes 

 out of the Mouth, but it ftill defcends by the Noilrils. 

 This Humour, I fay, diftilling out of the Arteries by 

 the fpongy Bones continually, doth in Procefs of Time 

 fo fill the faid Bones with filthy Matter, that, like a 

 Sink or Channel, being choaked up with Filth, there is 

 not fo free a Paflage for the Humour, as when the Dif- 

 eafe firft began ; fo that the Aiatter by that Means is 

 there ftay'd, and by its Continuance there it acquires fo 

 bad a Quality, that it corrodes and cankers thofe Bones, 

 and indeed ulcerates and gangrenes all the Paflages of 

 the Noftrils, till it has mortify'd and confum'd them (as 

 happens fometimes to Venereal Perfons) and at length de- 

 ftroy'd the Beall ; for indeed it is feldom or never cura- 

 ble, when it is once come truly to be a Canker. 

 " Nov,' by theFoulnefs of thefe Bones (as I have faid) 

 that Matter or Snot which doth defcend by thefe Paf- 

 fages (which indeed doth at length drivel down in a 

 greater Quantity than before, by reafon of the Paflages 

 being widen'd, from the Parts being gnawn afunder by 

 the canker'd Humour) I fay, that Matter or Snot, 

 which defcends after this, is of a contrary Colour to 

 what it ufed to be ; for it is become more black and 

 waterifh, mixed with a little red, and hath a very ill 

 Smell i but this Alteration happens not from the Mat- 

 ter's flowing from a new Part, but is caufed by reafon of 

 the Foulnefs of the Parts through which it palTeth ; for 

 from thence it hath its Dye in a great Degree. 

 " Not but yet there is another Caufe of it, which is the 

 greater Foulnefsofthe Blood ; for as the Beginning of the 

 Diftemper did proceed from the Corruption or Depra- 

 vation of the Blood, which was become, as it were, de- 

 generate from its fpirituous, balfamick, and volatilized 

 Condition, into a flat and vapid State, like to dead Wine ; 

 fo in Procefs of Time, for Want of the Spirits to quicken
