But in this Operation, as well as in Bleed- /« Bleeding 

 in^s a particular Regard ought to be had to '^^^ P^'g^'^g, 

 the Strength of every Plorfe, becaufe the Irri- ^^J ^trevgth 

 tation that this kind of Phyfick makes in the |^^^ arded^ 

 Stomach and Guts, when it is powerful, ^ ^^^"^ 

 occafions fuch diforderly Agitations in the Blood and Spirits, 

 as caufe violent Sicknefs, attended with cold damp Sweats, 

 and fometimes convulfive Motions : And all this I have 

 feen frequently happen to Horfes while under this Opera- 

 tion ; and therefore they ought not only at that Time to 

 be carefully look'd after, but their Phyfick fliould be quali- 

 fy'd with fuch Mixtures as will prevent it from adhering 

 loo clofely to any Parts of the (3uts. 



But what relates to this, and all other Operations, will, 

 I doubt not, be perform'd to the Farrier's Satisfaction in. 

 the Sequel of this Treatife, \vhere all thofe general Rules 

 fhall be juftly and methodically applied.

CHAP, VI, 



Of the Fe'uers of Horfes in general, 



[OST of thofe who have treated of the 'T'-^^ Sleur de 

 Difeafes of Horfes, have defin'd a Fe- Solleyfell'; O- 

 ver to be a preternatural Heat of Blood ; and t'"'^*' ^oTicem- 

 the Sieur de SoUeyJell has compar'd it to the '"^ " ^''''"'^ 

 " Ebullition of Wine in a Cask, where the Liquor being 

 " agitated, heated, dilated, and fermented, and having no 

 " Vent, breaks impetuoufly through all Obllacles, fpread- 

 ** ing its Steams and Vapours all around, and appe:irs fo 

 " muddy, that we cannot difcern the lead Drop of Wins 

 " in the Veflel. But after thefe diforderly Motions, all 

 " the Impurities that were in the Wine are feparated ; the 

 *' Lees fall to the Bottom, a Sort of Scum floats on the 

 " Top, and the Concavity of the Veflel is covered wilh a 

 " Sort of crufliy Subftance". This Comparifon betweca 

 the State of the Blood, and Wine thus pent up in the Cask, 

 is, according to that Author, a true Idea and Reprefenta- 

 tion of a Fever, which, as it is obvious to Senfe, will, no 

 doubt, fatisfy a good many Readers ; but yet, as the A- 

 greement is only in fome few Circumfl:ances, and not in 

 the whole, I fhall therefore give a fliort Account of a Fever, 

 a? it is founded on the Strudure of the Blood, and the Vef- 

 ^els in the which it flows.
