THE PREFACE. _The Generality of Men, have for a long time had too Narrow Thoughts of Physick, as if it were in a manner Confin’d to little more than Internals, without allowing themselves the Liberty of common Reasoning, by which they easily might have found that the Humane Body is liable to, and requires several Administrations of a very Different Nature, and that it is very unreasonable to suppose, that since there are so many ways for Diseases to enter upon us, there should be so few for Health to return by. Internals do indeed make up the far greatest part of the Means of Cure, but yet there are Considerable Cases, where the very Nature of the thing requires other Methods; and this would appear very obvious, if it were not for our too Partial Consideration of the Body of Man, by attributing too much to the Fluids, and too little to the Solids, both which, tho’ they have a Mutual Dependance upon one another, yet have each of ’em some Proprieties, and if out of Order, require something particular in the Application to restore ’em again. Consent in the Solids, answers to Mixture in the Fluids; and as an ill Ferment, as soon as it comes into the Blood, diffuses and mixes it self with the whole Mass, and cannot often be extirpated, till the Medicine given for that end, has been taken so long as to be diffus’d and intimately mix’d with the Blood likewise; so a Violent Seizure in one of the Solid Parts, commonly draws all the rest into Consent, and a particular Application to the Place primarily affected shall do no good, when a Universal one shall Cure; and a thing which would be trivial and Vain, if us’d as a Topick, shall by a Universal Administration prove of the greatest Importance. We see Contraries often prove Remedies to one another in the
