¶Of the Feauer putrida. Cap. 36.

FEbris putrida, & rotted feauer hath that name of rotted humours, of the which it is bred. And Isaac saith, yt this rottennes cōmeth in this manner: of euil humors & of superfluitie thereof gathered in some part, by strange heate & vnkind, yt cōmeth by some chance, ther is a man∣ner distroubling & mouing of these hu∣mours, Page  100 and by that straunge heate, the humours boile and be not defied, neither departing is made betweene the euill parts and the good. And so the good parts be not cleansed, but medled with ye euill partes by such boiling. And therefore needes the parts be corrupt and ros••ed. Then when thicke matter and grease and gleamye, so ioyned in the bodye, mooueth by heate, it needeth that it bee resolued and shedde into vapour, the which vapoure entereth into the thing that is moyst and thicke, and bideth there, and mooueth and biteth it selfe, and may not fréelye passe out for great∣nesse and thicknes of matter that letteth it: And so it is corrupt and rotten. And to this manner rotting, the complection of young folke is disposed, namely their complection is hot and moyst, and bée not disposed thereto, when the heate and moysture passeth. And colde com∣plection and dry is not so disposed to rot∣tennesse. And therefore selde olde men haue rotted feauers, for drinesse of com∣plection drieth and ioyneth humource, and letteth and withstandeth the depar∣ting and shedding of matter that is and bee meame disposition to rottennesse. For coldness fresheth, and letteth the heart that maketh boiling and seething. Then it is openlye knowne, that the cause that maketh rottennesse is moy∣sture, that disposeth, and heate that moo∣neth humours, and maketh them boile: And the dregges thereof bée not depar∣ted nor cleansed, but alwaye medled to∣gether, as Isaac sayth. Therefore néedes they bee disposed to rottennesse, and namely straightnes and closing of pores in the bodye, helpeth to this rottennesse. For when the poores bée straight and stopped, the superfluitie may not bée re∣solued nor departed, nor passe out. And therefore it néedeth that the more moo∣uing of humours be made by heate, and more mouing and corruption: namelye, when such heat is vnkinde, & ruleth not kind but corumpeth it. Also these causes of rotting haue other causes without▪ yt helpe them in working, as vnmoderate dyet and trauayle and also inordinate medicines, & other such, that worke and bring to corruption and 〈…〉 wards, when they be take 〈…〉 warde to the body in v••ue manner and vnce∣uenable time. Then of moisture, so cor∣rupt in some part of the body is resol∣ued a hotte, and a corrupt smoake that goeth to the heart, and distempereth and grieueth the heart, & then this smoake theddeth it selfe into the veyns, and bree∣deth in the body and pipes a retted fea∣uer, as Isaac saith and Constantine al∣so. Then such rotted matter that is cause of a rotted feauer, is either conteined in some hollownesse of the bodie, as in the stomacke or in the liuer, or some where cise, and then it is cause of a feauer that is called Interpolata, ye commeth & go∣eth: or it is cōteined in ye veines or pipes, & then it is cause of a feauer continuall. The cause of the continuance of a rot∣ted feauer is corruption of a humour, & constraining of a vapour, that inflameth & burneth in pipes & veines. And so the cause & the solution of al rotted feuers is knowne in generall, whther they bée continuall or discontinuall.
