Chap, XLI. Of the Yellows or Jaundice. 149 



' by Slime or gritty Matter, or when the Roots of thofe little 

 Dudls that open into that Pipe are ftopt by the like Matter, 

 or comprefs'd by a Plenitude and Fulnefs of the Blood- vef- 

 fels that lie near them^ 



Sometimes that Diflemper proceeds from or accompanies 

 hard and fchirrous Obftrudions in the Liver, and fometimes 

 the Blood will be tindur'd in malignant and peftilential 

 Sicknelles, as the Difeafe mentioned by SolleyfelU which 

 he terms the Spanijh Evil, and which he obferved to be 

 predominant among the Horfes in his Time, for feveral 

 Years together, and to many proved mortal ; fometimes the 

 fame Symptoms will alfo happen upon the Bitp of an Ad- 

 der, or any other venomous Beaft. 



In thefe laft Cafes of Poyfon and Infeftion, the Liver, no 

 doubt, is inflam'd and fwell'd, and by that means bears its 

 proportion, from which the Yellownefs no doubt happens ; 

 but as this is only a Symptom, which may be remov'd by 

 all thofe things that are proper to carry off the Fever ; and 

 as we have already laid down fuch Methods as are proper 

 in Cafes oi A4alignity, we fhall only here confider it as any 

 other Secretion that is obllruded, and provide fuch Mean^ 

 as are proper to open the faid Obllrudions, 



When the Gall-pipe, or rather when the Roots of its 

 common Duds are any ways ftopt up, the Matter which 

 fhould be converted and turned into Gall, is taken up by 

 the V^eins, and carried back again into the Mafs of Blood, 

 giving it a yellow Tinduie ; fo that all the Parts of a Horfe 

 that have a Capacity of (hewing the Colcur, as the Eyes, 

 the Infide of the Lips, and even the Slaver from the Mouth, 

 will appear yellow. But as this Difeafe is contrary to that 

 (ort of Scouring where there is a Profufion of the G2ii\, and 

 there being little or none of it tranfmitted into the Guts, the 

 Excrements will therefore look of a light pale green, as if 

 the Aliment was only wafhed in the Guts. 



It is alfo to be obierv'd, when a Horfe has the Yellows, 

 he turns dull, heavy and fluggifh, low in his Spirits, and 

 faint, efpecially when he is put to the leaft Exercife ; and 

 when the Diftemper has continued fome Time upon him, 

 he lofes his Appetite, and becomes poor, lean and jaded. 



While the Obftrudlions are only in the Gall- pallages, it 

 is ealy enough to be cured ; but when the Liver is indured 

 and harden'd near thofe Pallages, as it fometimes falls out ; 

 or if there happen Impoftumations or Ulcers, the Cure will 

 then be very doubtful 3 for in this Jail Cafe it will have all
