Vapour, which Vapour ascending to the Head, there gathers into Clouds of Water, where dissolving, it falls back again, like Showers of Rain, where it sometimes falls in pouring Showers, other times like mizzling Rain. And the fuller of Moysture the Body is, the greater Showers of Rain fall down. This stopping the Passages of the Throat, causeth a straining and striving in the Throat, as when any thing goeth awry, or Crums or Bones lye in the Throat, or stop the Wind-pipe: for every part of the Body, if it be bound, or hurt, will strive and strain to help it self. But if the Constitution of the Body be Naturally or Accidentally Dry, the Vapour is thinner, and then it ariseth, like a steam in a Still, or Limbeck, where the Head, like the top of a Still or Limbeck, gathers that steam into a Dew, which falleth back in distilling Drops; which Drops trickling down the Throat, as Tears on the Cheeks, do rather tickle the Throat, than stop the Wind-pipe, or strain the Throat: but if the Rheum be sharp, or salt, it causeth a gentle smart, which is of such a kind of touch as tickling is; provokes a faint or weak Cough.
But Coughs that proceed from a decay of Parts, are, when any part of the Body is corrupted it becomes less solid; as from being a Solid Flesh, to be of a Jelly Substance, which dissolves with the least Heat, melting by degrees away; and as it melts, it falls into liquid Drops, which Drops tickle or smart those parts they fall or trickle on: for by reason the Inward Parts are as it were raw, or very thin skinned, they make it sensible of the least touch; besides, there is a faint strife, when the dissolved part falls from the other, which strife tickling, causeth a Cough; but the Cough is more or less, according as the part dissolves. But these tickling Coughs are the most dangerous Coughs, for the one causeth a Consumption, the other is caused by a Consum∣ption: for when these tickling Coughs proceed from the Body, they are caused from a Consuming Part, that melts and dissolves by degrees; but when it is Distillation from the Head, it cor∣rupts Parts by falling thereon, like as Water, with a constant dropping, will penetrate thorow a Stone; much more may a Constant Distillation corrupt a Spungie Matter, as Flesh; and according as the Rheums are fresh, salt, or sharp, the Parts decay flower or faster: for salt, or sharp Rheums, ulcerate the Parts, and destroy them soon.
Also Wind will cause a tickling in the Throat, as a tickling in the Nose, which causeth Coughs; for Sneezing is but a Cough thorow the Nose: but when Wind riseth thorow the Wind∣pipe, it causeth a Chine-cough; for as long as the Wind ascends, the Patient cannot draw in Air, but coughs so long, without drawing in of the Breath, till they are black in the Face, being as it were choak'd or strangled, or rather smothered almost to Death.
As for Remedies, those Coughs that proceed from a Super∣sluity of Moysture, or from Corrupted Humours, there must be
