THE Reason there are more sick in the Spring than in the Winter, is, that the Pores of the Body being closer shut in Winter, by the Contraction of the Cold, than in any other Season, keeps in the Fire, the Smoke, and Vapour, that should, and would if it could, issue out: But the Parts being stopp'd,
having not a sufficient Vent to transport a proportionable Quan∣tity, it lyes and corrupts; for want of Agitation, the Quantity increasing, it overcharges the Body, that by such time the Spring is arrived, the Body is so distempered, as it falls sick, the Cor∣ruption having bred a Malignity that infects the Noble Parts.
For the Body having more Vapour than the Natural Heat can digest, makes it not onely corrupt, for want of a sufficient Heat to purifie it, but that Corruption quenches out the Natural Heat, which causeth Agues; and begets an Unnatural Heat, which causeth Feavers, and the like Diseases; and the Corruption causeth the Small-Pox, Meazels, Imposthumes, Soar Throats, and many such kinds of Diseases.
But when this Distemper of the Body is joyned to the like Corrupted Vapours drawn from the Earth, it is most commonly deadly, and produceth great Plagues the Summer following, the Body being then like Rotten Wood, which is quickly set on Fire, and soon burnt out.
But if the Body hath a Sufficiency of Natural Heat to clarifie the Vapour, that arises from the Stomack, and Bowels, and to dry up the Superfluous Moysture, the Body is safe from Danger: but if the Body have more Heat than Moysture, it feeds upon the Noble Parts, and causeth Hective Feavers.
But Hective Feavers are seldome cured by the stoppage of the Pores: for the Natural Heat in the Body is like External Fire, which is extinguished if it be stopp'd, and hath not Vent.
But there are several sorts, or kinds, or manners of Unnatural Heat, caused by Obstructions, and other Accidents; as there is a Smothering Heat in the Body, caused by Obstructions; and there is a Smoking Heat of the Body, caused by too violent Ex∣ternal Motions. or such Meats that actually heat; also a Fiery Heat in the Body, caused by too much, and too strong Interior Motion: but these Heats, that are Moyst Heats, and Unnatural, cause Corruption.
