inclined to Wantonness by reason of his Youth, or sly Countenance, then the fore-mention'd Disease is to be call'd the Pox. In most Diseases of Women, they accuse the Mother. In Children, their Guess seems far more fallible; for a Child within the six Months being taken ill, restless, and froward, if there appear no evident Disease, he ever affirms it's troubled with Gripes; upon which he prognosticates, that if not speedily remedied, the Child will fall into Convulsion-Fits; but this not happening according to his Prediction, to prevent the Forfeiture of his Skill and Repute, endeavours to possess the Mother, and rest of the Gossips, it had inward Fits. The Child being past six Months, and falling indispos'd, then instead of Gripes, it is discompos'd by breeding of Teeth; but having bred all his Teeth, and being surpriz'd with any kind of Illness, the Doctor then avouches it is troubled with Worms: In short, take away these three Words, Obstruction, Consumption, and Scurvy, and there will remain three dumb Doctors, the Hackney Physician, the Prescribing Surgeon, and the Practicing Apothecary.
