Note 81 — OF THE Intermitting Fever, or Ague.
Reading edition
The common Account given of the Cause of Agues, and of the regular Return of their Paroxysms, has been: That the Ague takes its Rise from some Sort of Matter, bilious, or whatever it may be, either mixed with the Blood, or lodged in the Bowels, or in some other Part of the Body; that a great Part of this Matter is thrown out of the Body, in the Time of the Paroxysm; but that so much remains as serves by Way of a Ferment to assimilate other Particles to its own Nature; which, when collected in a certain Quantity, produce a new Fit; and, according to the Time that it takes to produce this Quantity, the Disorder assumes the Form of a Quotidian, Tertian, or Quartan Ague.
