Of purging with Purgation, or Glister.
PVrgations is defined by the Physitians, to be the emptiyng or voiding [ 30] of superfluous humors, annoying the body with their euill quality. For such humors bring euill iuyce and nutriment, called of the Physitians Cacochimia, which when it will not be corrected or holpen with good dy∣et, alteration, nor by the benefit of nature and kindly heat, then it must needes be taken away by purgation, vomit or Glister. But forasmuch as Horsses are not wont to be purged by Vomit, as men be, I will speake heere onely of Gli∣sters and purgations.

For a Glister, by clensing the guts, refresheth the vital parts and prepareth, the way before. And therefore whensoeuer a Horse is surfeted and full of euill humors, needing to be purged and specially being pained in the guts, I would wish you to begin first with a Glister, least by purging him by medicine vppon the sudden, you [ 50] stir vp a multitude of euill humors, which finding no passage downeward because the guts be stopt with wind and dregges, do strike vpwardes, and so perhaps put the horse in great danger.
But now you shall vnderstand that Glisters be made of foure things, that is to say, of de∣coctions, of Drugges, of Oyles, or such like vnctious matters, as butter and soft grease, and fourthly of diuers kindes of salt to prouoke the vertue expulsiue. A decoction is as
