As to the Former, he shews, in what sorts of Patients, and at what time of the Fever, Phlebotomy, or Vomiting, or both, are to be used; and when and where not: In what space of time the Depuration if nature be not disturbed or hindered in her work, will be perform'd: When Purgatives are to be administred: How that Diarrhea's happen, if the Patient had in the beginning
