when the Stomack is distemperedly hot, the Humors in the Stomack boyl as Liquid Substances on the Fire; those boiling Motions bearing up the gross Humors beyond the Mouth of the Stomack, and, causing a Dispute between the Breath and Humors, produce the Effect of Straining, or Reaching upwards towards the Mouth, much like the Nature and Motions of Vomiting: but, by reason those Motions are not so strong in Coughing, as in Vomiting, the Coughing Motions bring up only pieces or parts of superfluous Flegm, or gross Spittle. The like for corrupt Humors. Other Coughs proceed from Unnatural or Distempered Heats; which Heats cause Unnecessary Vapours, and those Vapours ascending up from the Bowels, or Stomack, to the Head, and finding a Depression, are converted or changed into a Watry Substance; which Watry Substance falls down, like mizling or small Rain, or in bigger drops, through the passage of the Throat and Wind-pipe: which being opprest, and the Breath hindered, causes a Strife; which Striving, is a Straining; like as when Crumbs of Bread, or Drops of Drink, go not rightly through the Throat, but trouble and obstruct the Wind-pipe, or when any such Matter sticks in the passage of the Throat: for, when any Part of the Body is obstructed, it endeavours to release it self from those Obstructions: Also, when the Vapour that arises, arises in very Thin and Rarified Vapour, that Rarified Vapour thickens or condenses not so suddenly, being farther from the degree of Water; but when condensed into Water, it falls down by drops; which drops trickling down the Throat, (like as Tears from the Eyes trickle down the Cheeks of the Face) the Cough is not so violent, but more frequent: but if the Rheum be salt or sharp, that trickles down the Throat, it causes a gentle or soft smart, which is much like the touch of Tickling or Itching, which provokes a faint or weak Strain or Cough. Also, Wind will provoke to Strain or Cough: The Motion of Wind is like as if Hair should tickle the Nose. Or, Wind will cause a tickling in the Nose, which causes the Effect of Sneezing: for, Sneezing is nothing but a Cough through the Nose; I may say, It is a Nose-Cough. And Hickops are but Stomach-Coughs, Wind causing the Stomack to strain. Also, the Guts have Coughs, which are caused by the Wind, which makes a strife in the Guts and Bowels. Other Coughs are produced from Decayed Parts: for, when any Part is corrupted, it becomes less Solid than naturally it should be: As for example, The Flesh of the Body, when corrupted, becomes from Dense Flesh, to a Slimy Substance; thence, into a Watry Substance, which falls into Parts, or changes from Flesh, into a Mixt Corrupted Matter, which falls into Parts. The several Mixtures, or Distempered Substances,
