In the Third Section he treats of Intermittent Feavers, or of Agues: Where he discourses of the times of the Cold and Hot fits, and of that of the Separation of the subdued aguish matter: Finds difficulty in giving a satisfactory accompt of the return of Fits: distinguishes Agues into Vernal and Autumnal: Takes notice, that as there are few Continued Feavers, so generally there are only Quotidians and Tertians, in the Spring; and only Tertians and Quartans in Autumn; Of which having offered Reasons, that seem considerable, he proceeds to his Method of curing them; and, laying much weight upon the said difference, he prescribes and urges different ways to be used in that cure: Interserting among other things these notes; First, that the Period of Fermentation in Feavers, both Continued and Intermittent, is (if left to Natures own conduct and well regulated, if need be, by Art) perform'd in about 336. hours or 14 dayes; subducting in Intermittent ones, the hours of intermission, and counting 512 hours for every Paroxism; and imputing the excursion beyond that time to the disturbance given to nature by the error of Practitioners. Secondly, that whoever hath had a Quartan formerly, though many years be pass'd, shall, if he chance to have another, be soon freed from it; and that a Physician knowing that, may confidently predict this.
