ABSTRACT
§. I. IN order to attenuate the Juices, to break the Cohesion of their Parts, to destroy their Viscidity and Glewiness and to make them sufficiently thin, and fit to flow in the small Vessels with Ease, those Medicines are chiefly to be chosen, which either by their own Nature are the most active, by the Figure of their Particles, are the most sharp and dividing, by their Weight are endu'd with the greatest Force and Momentum; or lastly, which by Experience are found (without knowing a Reason why) to be the most effectual for producing these Ends.
