In the Fourth Section, the Author, in conformity to the Custom of those that write of Feavers, discourses of the Small-pox; and First, examining the cattle of this sickness and its universality, delivers his peculiar opinion of the bloud's endeavouring a Renovation or a New Texture (once at least in a Mans life) and is inclin'd to preferr the same to the received doctrine of its malignity. Then, having laid down, for a foundation of the Cure, the two times, of Separation and Expulsion, he argues as well against too high an Ebullition or too hasty a separation (by a hot diet or high Cordials) as against too languid a one (by Blooding, Purges, and Cooling medicines.) The like he does to the Time of Expulsion, forbidding both immoderate Heat (whereby Natures expelling operation is disturbed by a precipitated and too thick a crowd of the protruded pustuls,) and too much Cooling, whereby due Expulsion is hindred. In short, he advises, to permit Nature to do her own work, requiring nothing of the Physician, but to regulate her, when she is exorbitant, and to fortifie her, when she is too weak. He concludes all, with delivering a Model of the Method, he would use for his own only Son, if he should fall into this Sickness.
