But this prouision of nature is oftentimes defectiue: as when it is cut off by violent causes, and the part left destitute of this familiar humor, which should serue both for the comfort of the infant, and of the part it selfe: which finding offence thereby doth communicate it vnto the other partes with which it hath affinitie according to _Hyppocrates_ doctrine. _1. Morborum muliebrium_, and _Aristotle, de generat. animal. cap. 11. vteri euacuati sursum ascendunt & præfocationes faciunt. Cordæus_ giues vs an example of one who by chaunce cutting a vaine in her leg, whereupon she did bleede plentifully, fell into a fit of the Mother, and by moist and nourishing diet was recouered. The reason whereof _Hyppocrates_ referreth to the ouerdrying of those parts through large euacuation of bloud, wherby the matrix doth labour by such motion as it hath to supply it selfe with moysture from other parts of the body: or as _Mercurialis_ doth enterpret it, doth impart by communitie (as is aforesaid) the offensive qualitie vnto the braine, and by that meanes procures convulsions, &c. _Gallen_ refferreth it into the ouercooling of those parts which necessarily must follow a large euacuation of bloud, which coldenesse being very offensive vnto the nerues and neruous partes by consent and compassion offendeth the braine also, and by that meanes may procure the former _Symptoms_. [Sidenote: _Excesses._] [Sidenote: _Gal. loc. affect. 6_ _Pereda in paschalium lib. 1. cap. 58._ _Altomarus._ _Syluius._] And as the want and scarsitie of bloud may procure this griefe, so the abundance & excesse thereof doth more commonly cause it, where the patients do want those monethly euacuatiõs which should discharge their bodies of this superfluitie: as we see in strong and lustie maidens, who hauing ease and good fare inough, haue their vaines filled with plenty of bloud, which wanting sufficient vent distẽdeth them in bulck and thicknes, and so contracteth them in their length, whereby the matrix is drawne vpwards or sidewards, according as the repletion is, whereupon followeth a compression of the neighbour parts, as of the midrif which causeth shortnes of breath, by straightning the instruments of respiration of their due scope. But if this bloud wanting his proper vse doe degenerate into the nature of an excrement, then it offendeth in qualitie as well as in excesse, and being detayned in the bodie, causeth diuers kinds of _Symptoms_, according to the qualitie and degree of the distemperature thereof.
