In the _Second Section_, he treats of the _Symptoms_, accompanying _Continued_ Feavers; as _Phrensies_, _Pleurisies_, _Coughs_, _Hicoughs_, _Fluxes_, &c. Shewing, both whence they are caused, and how they are to be cured: Where having inserted a considerable _Paragraph_, touching a certain _Symptomatical_ Feaver in the _Spring_, to be cured like Plurisies; he mentions among many Observables, this, as a chief one, that _Laudanum_, or any other _Narcotick_ given against the _Phrensy_, in the beginning, progress, or height of a Feaver, does rather hurt, than good, but in the declination thereof, is used with good success. To all which he subjoins a particular {212} accompt of the _Iliac Passion_ (esteem'd by him to be sometimes a _Symptome_ also of Feavers;) not only discoursing of its cause (a preposterous inversion of the Intestins, proceeding either from Obstruction, or Irritation,) but adding also a very plain way of Curing the same; and that not by the use of _Quick-silver_ or _Bullets_ (by him judged to be frequently noxious) but only by _Mint-water_; and the application of a Whelp to the Patients stomach; to strengthen the same, and to reduce it again to its natural motion. 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 51/2 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_. {213}
