All _Sweating-Diseases_ are somewhat of the nature of Dropsies; but they are (at least, seem to be) more Exterior, than Interior Dropsies: but, though there be Sweating-Diseases which are Irregular; yet, Regular Sweating is as proper as Regular Breathing; and so healthful, that Sweating extraordinary, in some Diseases, occasions a Cure: for, Sweating is a sort of Purging; so that the evacuation of Sweat, through the Pores, is as necessary as other sorts of evacuation, as Breathing, Urine, Siege, Spitting, Purging through the Nose, and the like. But, Excess of Sweating, is like other sorts of Fluxes, of which, some will scowr to death; others vomit to death; and others the like Fluxes will occasion death; the like is of Sweating: so that the _Sweating-Sickness_ is but like a _Fluxive-Sickness_. But, as I said, Regular Sweating is as necessary as other ordinary Evacuations: and as some are apt to be restringent, others laxative; and sometimes one and the same Man will be laxative, other times, costive; so are Men concerning Sweating: and as some Men take Medicines to purge by Stool, or Vomits, or Urine; so they take Medicines to purge by Sweating. And, as Man hath several sorts of Excremental Humours, so, several sorts of Sweats; as, Clammy Sweats, Cold Sweats, Hot Sweats, and Faint Sweats: and, as all Excess of other sorts of Purgings, causes a Man to be weak and faint; so doth Sweating. CHAP. VIII. Of COVGHS. There are many several sorts of _Coughs_, proceeding from several Causes; as, some Coughs proceed from a Superfluity of Moisture; others from an Unnatural Heat; others from a Corruption of Humors; others from a Decay of the Vital Parts; others from sudden Colds upon Hot Distempers: Some are caused by an Interior Wind; some Coughs proceed from Salt Humors, Bitter, Sharp, and Sweet: some Coughs proceed from Flegm, which Flegm ariseth like a Scum in a Pot, when Meat is boiling on a Fire: for
