CHAP. XVIII. Of the Vlcers of the Kidneyes and Bladder.
VLcers are caused in the Kidnyes and Bladder, either by the use of acride meates, drinkes, or medicines, as Cantharides; or else by the collection of an acride humor bred in that place, sent or falne thither; or else by the rupture * 1.1 of some vessell, or an abscesse broken and degenerated into an Vlcer, as it sometimes comes to passe. They are discerned by their site, for the paine and heavinesse of Vl∣cers of the Reines comes to the Loynes, and the Pus or matter is evacuated well and * 1.2 throughly mixed with the Vrine.
Neither doth the Pus which flowes from the renies stinke so ill, as that which is cast * 1.3 forth of the bladder; the reason is, for that the bladder being a bloodlesse, fleshlesse & membranous part hath not such power to resist putrefaction; that pus which flowes * 1.4 from the Kidneyes never flowes without water; and although by long keeping in an Vrinall, it at length subsides or falls to the bottome, and may be seene separated; yet when it is first made, you may see it perfectly mixed with the Vrine; but that Pus wch * 1.5 flowes from the bladder is oft times made alone without Vrine; & usually it comes to passe that the Pus, or matter which flowes from the ulcerated Kidnyes, hath in it cer∣taine caruncles, or as it were haires, according to the rule of Hippocrates. Those who in a thicke Vrine have little ca••uncles, and as it were haires come forth together therewith, they come from their Kidnyes; but on the contrarie those who have certaine bran-like scailes come from them in a thicke Vrine, their bladder is scabby or troubled with a scabby Vlcer.
For the cure; it is expedient that the belly be soluble either by nature; or Art and * 1.6 the use of mollifying Glysters. And it is good to vomit sometimes, so to draw backe the humors by whose confluxe into the affected part the Vlcer might bee seed and made more sordide and filthy. You must beware of strong purgations, least the hu∣mors * 1.7 being moved and too much agitated, the matter fit to nourish the Vlcer may fall downe upon the Kidnyes or bladder. The ensuing potion is very effectuall to mundifie those kind of Vlcers.

Let him take one thereof in the morning dissolved in Barly water or Goates milke. Galen bids to mixe honey and diureticke things with medicines made for the Vlcers of the Reines and bladder, for that they gently move * 1.10 Vrine, and are as vehicles to carry the medicines to the part affected. Vlcers of the bladder are either in the bottome thereof, or at the necke and urinary passage.
If they be in the bottome, the paine is almost continuall; if in the necke, the paine * 1.11 then prickes and is most terrible when they make water and presently after. The Vlcer which is is the bottome sends forth certaine scaly or skinny excrements to∣gether with the Vrine; but that which is in the necke, causes almost a continuall Tentigo. Those which are in the bottome are for the most part incurable, both by
