How these two substances by consent may affect the whole bodie according to their seuerall natures, hath beene shewed before: But one scruple remaineth here to be discussed, namely how this venemous matter may lurke so long in our bodies in silence not shewing it self but at certaine times only.
Galen Loc. affect. 6. 5. Petrus Salius de affect. particu. laribus pa. 326 in the former place declareth this by the example of a mad dogge, whose venom being receiued of us, although but by the foame of his mouth, will remaine sometimes sixe moneths within our bodies vndiscouered, and then hauing gotten more strength and ripenes vnto it selfe, Altomarus. and opportunitie of conuaying his euil quallity vnto the parts, breaketh forth to open view by diminishing or peruerting the faculties of those parts. I had once a patient in Kent who feeding vpon a mad hogge which hee had killed for couetousnesse sake, found himselfe distempered therewith at the first, but within fiue or sixe moneths after grew suddenly to be starke madde, and before his death, being by Phisicke restored to some reasonable vnderstanding, he confessed the eating of that hogge to haue beene the true cause of his disease. Diuers reasons may be yeelded of this as well as of the fits of intermittent agues of Epilepsies, of sweating, &c. which oftentimes haue their due recourse by the yeare, moneth, weeke, day or houre, according to the nature of the humor: Ga. loc. affect. 6 Felix Platerus de causis febrium. pag. 63. 65 66. &c.
Mercatus. Fernel. patholog. li. 6, cap. 16 which being crude expecteth his concoction in our bodies and giues no signe of his presence vntill such a proportion of it be digested and resolued into vapours, as for the offẽce therof the part affected is not able to brooke and for the weaknesse of the expulsiue facultie not able to auoide out of the bodie: but filling the vaines, arteries, and the habit of the body, is communicated to the principall parts; diminishing or deprauing their functions so long, vntill that portion of vapours be discussed through naturall heate: and ceasing againe so long vntill by fermentation and concoction, another portion of the corrupt humor shall be digested.
The vniformitie of this humor and of the heate of concoction causeth the vniformitie of fits. And this is the cause of the due periods or circuites which oftentimes are obserued in this disease, whereof wee haue spoken before: 2 according also to the condition of the part affected, which seruing as an euacuatorie to the whole bodie, is accustomed to such kind of humors and therefore can endure them better then other parts can. Quia multum.
Quia prauum.
Quia insuetũ. And this is another cause why this humor giues no signe of his presence vntill it may communicate with the principall partes: which are soone offended either with the plenty of those vapours, or with the malignity, or with the vnwonted and vnaccustomed approach of them.
The externall causes of this disease are either such things as are ordinary and necessary for our life and which we cannot shun, as our meate and drink, motion and rest, sleepe and watching, euacuation and perturbations of the minde: or such things as happen vnto vs accidentally, and may bee shunned by vs, as bathes, ointments, plaisters, cloathes, smelles or vapours, medicines, venus, noyses, riding, swimming, sayling, wounds, contusions, falles, biting of venomous beasts, &c. which may be also referred to the former kindes. These and such like as they are the externall causes of all diseases, our bodies being subiect to be hurt and offended by euery one of them: so they are oftentimes accessary to this particular disease.
The aire which compasseth our bodies and which we breath into our bodies is the occasion of many infirmities in vs, Fernel. li. 1. de morborũ causis. if either it be distempered in quallitie or corrupted in substance, or suddenly altered. And this may be the cause why women are more subiect vnto this disease at one time of the yeare than at another, according to the constitution of the ayre: as in the winter time, by reason of colde and moyst weather the humors of our bodies are increased and made more crude and grose, and our pores stopped, whereby expiration is hindered, &c.
Mathaus de gradi. Mercat. Rondel. cap. 69 But especially wee doe obserue that breathing in of sweete sauours doth commonly procure these fittes, either for that the matrix by a naturall propertie is delighted with sweete sauoures, Hier. Mercuria as the liuer and spleene with sweete meates, or because the animall spirites of the braine beeing thereby stirred vp to motion, doe by consent affect the matrix with the like.

Meate and drinke is the Mother of most diseases, whatsoeuer the Father bee, for the constitution of the humors of our bodies is according to that which feedes vs. And therefore it is reckoned as a principall externall cause of diseases.

The Essex Gentlewoman of whome I spake before, Heurnius de morbis capitis pag. 310. could neuer take any comfortable sustenance, but she was sure to haue a fit of the mother. The reason of this may be the same which we haue alleaged of sweet vapours.
