Now according to this description let vs consider how by consent, the principall partes of the bodie may bee affected from the matrix. [Sidenote: _Fernel. pathologiæ li. 6. ca. 16_] [Sidenote: _Forestus lib. 10 obseru: 115: in scholsis._] The partes of our bodie doe suffer by consent[21] two manner of wayes. The one is when they doe recyue some offensiue thing from another parte which is [22]called _Communitas non absoluta_. And this is either a qualitie as in venemous and infectious diseases, where the malignitie creeping from one part to another doth alter the qualitie of the parts as it goeth, and at the last is communicated to the principall parts, as the head, heart, liuer, longs, &c. or a substance which either by manifest conducts, as vaines, nerues, arteries, &c. or by insensible pores (as _Hyppocrates_ saith, our bodies are transpirable, and transmeable) is conuaied from one part to another: whether it be a vapour or a humor, as wee doe commonly obserue in the fits of feuers, where a vapour arising from the part affected, disperseth it selfe through the whole body, and affecteth the sensiue parts with colde or heate, the motiue parts with trembling, the vitall parts with fainting, sounding, inequalitie of pulse, &c. the naturall parts with deiection of appetite, subuersion of the stomacke, &c. vntill nature haue ouercome and discussed it. In these Feuers also many times humors are so plentifully sent vp vnto the braine, as by custome or long continuance they breede some proper affect there.
